How to choose a dishwasher. Features, functionality, types and selection criteria

Modes and their duration

Let's also talk about the modes that are most often found in dishwashers, and see how long each of them lasts. Most dishwashers have 4 main washing programs:

• Quick wash - assumes that the machine washes the dishes at 35C, rinses them twice, which takes about 30 minutes.
• Normal wash - includes pre-rinse, dishwashing at 65C, triple rinsing and drying, this takes about 104 minutes.
• Economical washing - includes pre-rinse, dishwashing at 50C, double rinsing and drying, the mode is designed for 155 minutes.
• Intensive wash - includes pre-rinse, dishwashing at 70C, four rinsing stages and drying, the process takes 109 minutes.

Some dishwashers also have the following programs:

• “Eat-Load-Run” - a mode that involves loading dishes immediately after eating, the machine washes the dishes at 65C, rinses and dries them, completing all stages in just 30 minutes;
• Delicate – washing items at 45C made from materials such as porcelain, crystal, glass;
• Car wash - this program recognizes the degree of contamination of dishes and automatically sets the required amount of water, powder and the duration of the washing cycle.

In addition, modern dishwashers, for example Bosch machines, have a Time Saving function (Varlo Speed), which, depending on the selected mode, allows you to save from 20 to 50% of the time on washing dishes.

strong>However, when washing time decreases, energy consumption increases. Here you can choose whether it is more profitable to wash for a long time, about two hours with reduced energy consumption, or 1 hour, but consume more electricity.

Dishwasher models: mode duration

Let's look at several different models of dishwashers from different brands and the cleaning time for these machines.

ELECTROLUX ESF 9451 LOW

• Quick wash – lasts 30 minutes.
• Intensive - lasts 65-75 minutes.
• The main one is 100-110 minutes.
• Economical - 120-130 minutes.

AEG OKO FAVORIT 5270i

• Quick wash – lasts 30 minutes.
• Intensive - lasts 100-110 minutes.
• Main – 89-99 minutes.
• Bioprogram - 87-97 minutes.

HANSA ZWM 4677 IEH

• Quick wash – 40 minutes;
• Express 60 – 1 hour;
• Gentle wash – 110 minutes;
• ECO – 165 minutes;
• Regular – 155 minutes;
• Intensive – 130 minutes.

Gorenje GS52214W(X)

• Standard wash – 155 minutes;
• Intensive wash – 130 minutes;
• Delicate wash – 110 minutes;
• Economical washing – 165 minutes;
• Quick wash – 40 minutes;
• Hot rinse – 60 minutes;
• Cold rinse – 8 minutes.

So, in general, the duration of the dishwashing cycle in machines of different brands, for example Bosch, Siemens, Hansa, etc., is practically the same. Look at the display when selecting a program or in the instructions for the equipment for exactly how long it takes to wash the machine. No matter how long she washes, you can calmly go about your business during this time.

Dishwasher interior

At first glance, the operation of a dishwasher seems simple: install the unit, connect it, put detergents in the right places, arrange the utensils, select a program, start the equipment. Then you can forget about the dishes for a while and do something more enjoyable.

But I wonder what is happening inside the dishwasher at this time? After starting the machine, water flows into a special tray through an open valve. Enriched with detergents and regenerating salt, it heats up to the temperature you set.

The process itself is identical to washing dishes by hand. The structure and operating principle of dishwashing equipment are described in detail here. We recommend that you read this very useful information.

It depends on the program you have installed and consists of three to four stages:

• soaking if the dishes are very dirty;
• washing;
• rinsing;
• drying.

The duration of these periods is influenced by the initially set water heating temperature. The higher the threshold you set, the longer you will have to wait for the cycle to end.

The dishwasher unit consists of the following elements: control panel (1), sprayer blocks - upper and lower (2, 3), float valve (4), drain hose (5), power cable (6), supply hose (7), filter (8), intake valve (9), engine (10), pump (11), heating element (12), gasket (13), button (13), latch (14)

When soaking, which is sometimes called a pre-wash, the main dirt is washed off from the dishes with cold water without the use of chemicals from the main container. This function is convenient if dishes are loaded into the machine in stages as they accumulate. It will prevent dirt from sticking tightly to previously loaded kitchen items.

The washing itself involves treating the dishes with hot water at about 80ºC. You can simply increase the washing time, but the advantage of the first option is that no detergent components are used.

The diagram shows the process taking place inside the dishwasher. It is important to load high-quality washing products and select the correct mode before starting

Water along with the chemical composition is sprayed using special tubes located at the top or bottom of the body. The rocker washes dishes more efficiently. During rotation, it sprays water jets in all directions under powerful pressure.

At the end of the washing stage, the PMM automatically turns on the next one - rinsing and drying.

Experts do not consider pre-rinsing a mandatory procedure if the PMM is not started immediately. It is enough to simply remove residues from plates and pots so as not to clog the machine with them.

Rinsing in a dishwasher, similar to a washing machine, involves two stages. This is the only way to completely remove detergents from all surfaces of washed dishes.

Standard operating modes

Dishwasher programs are a sequence of operations that the microprocessor performs.

The main parameters are:

1. Presence or absence of pre-soaking mode.
2. Water heating temperature.
3. Duration of the program.

After repeated use of the PMM, it will be easy to recognize how it functions and detect malfunctions by ear.

Types of drying in PMM

Drying completes the washing cycle. It comes in three types: blowing with heated air (turbo-drying), an intensive process with a heat exchanger, and condensation.

The first method involves blowing warm jets of air over the treated dishes. The implementation of the process is possible thanks to the presence of a fan built into the design. Drying occurs faster, but energy consumption is increased.

Enhanced drying is carried out due to the independent movement of air inside the housing as a result of the pressure difference. This method gives good results with more economical consumption of electricity.

The drying phase completes the operation of the machine. PMMs equipped with turbo drying are expensive, others are somewhat cheaper; when choosing, you should consider what is more important for you - a shorter drying stage or higher electricity bills

During condensation drying, drops of water evaporating from the surface of the dishes are transformed into condensation and settle on the walls, then flow down. This drying method takes a lot of time, but if there is nowhere to rush, then this method is the best.

Standard cycle time

Modes for different PMM models may differ. Still, there are four basic washing modes in a dishwasher, which each manufacturer includes in its program. These modes are called fast, normal, economical, intensive. Let's consider each of them as guidelines for choosing a dishwasher.

When choosing a quick wash, the pre-wash and dry function is no longer required. The process lasts about half an hour. In the instructions for some models, this type of dishwashing is called rinsing. This mode is used when a small amount of not very dirty dishes has accumulated.

In normal mode, which includes a fully completed cycle, the dishwasher runs for an average of two hours, of which:

• Rinse - from 5 to 10 minutes.
• Main wash – up to 50 minutes. at a water temperature of 65⁰.
• Rinse in three steps - up to 10 minutes.
• Drying - the rest of the time.

Economy mode significantly reduces time by increasing temperature and pressure. This results in less water being wasted, but energy consumption increases. The program contains a preliminary rinse, a wash at 50⁰, a double rinse, and drying.

Very dirty dishes are washed using an intensive mode for 2-3 hours. This program includes pre-rinsing, washing at 70⁰, rinsing in four steps, drying.

For efficient operation of the unit, it is necessary to place the very dirty surface of the dishes closer to the washer fluid sprayer. Knives in a dishwasher that is not equipped with a special container are placed with the blades down, and forks are placed with the teeth up

It is better to wash pans and pots in the “pre-soak” mode. Particularly greasy kitchen utensils should be kept in the sink under very hot running water before loading. This will help the dishwasher do a better job.

Some models are also equipped with the following programs:

1. EatLoad-Run , which allows you to load dishes directly from the dining table. There is a quick wash at 65⁰, then rinsing and drying, and all this in 30 minutes.
2. Wash delicate at 45⁰ . Used for crystal, porcelain, glass. Duration: 110 minutes.
3. Car wash (Auto) - this program, without outside intervention, determines the degree of contamination and automatically sets the required amount of water, detergent and the duration of the process. The usual water temperature in this mode is from 45 to 65⁰, duration is 2 hours 40 minutes.

The latest PMM models have the Varlo Speed , which allows you to reduce time by up to 50%. Not everything is so simple here - while saving time, electricity consumption increases. When choosing a mode, you need to calculate what is more profitable for you - saving time or energy.

Floor-standing models that hold a minimum of eight sets have a half-load mode . This means that only one of the available two baskets is loaded. At the same time, the washing time is not reduced, but the volume of water, detergents, and electricity used decreases.

The variable washing program provides for simultaneous processes - washing dishes in intensive mode and soaking. These two jobs happen in different baskets. Using the program allows you to save about 25% of water while maintaining excellent washing quality.

To start the dishwasher, you need to correctly decipher the icons on the panel. Sometimes they are signed, but in the language of the country of origin

“Delay Start” function is very relevant . With its help, you can move the start by 1 – 24 hours. If you have a double tariff for electricity, this is very convenient.

Additional functions of PMM

In parallel with dishwasher modes, they can also have additional functions. Almost all of them are equipped with leakage protection. If there are small children in the house, you need a unit with the ability to lock the control panel or door.

The ability to add forgotten dishes after starting the machine is also a very convenient feature. Elite models are equipped with loading sensors. In this mode, the PMM selects both the volume of water and the time spent on the cycle.

Some models have additional elements - sensors for monitoring water purity and hardness. A sensor for monitoring the degree of water purity forces the unit to rinse everything loaded into the machine until the liquid becomes perfectly clean. If the water is very hard, the machine will determine how much softening salt to add.

The panel for launching additional functions for built-in PMM models is located at the end of the door

Built-in units in working condition project a red beam onto the floor plane. When the process is completed, it disappears or its color changes to green. This is very convenient, because... makes it possible to monitor the operation of the built-in dishwasher.

Control of washing modes

All modes in the PMM are coordinated in two ways: electromechanical and electronic. The second method is more comfortable, and all modern models are equipped with it. The first provides for the presence of buttons, switches and keys on the body, and they are controlled manually.

Control of some PMM models is simplified due to the presence of clear symbols in the designation of standard programs. These are glasses, pots and other items (+)

With electronic control, both the washing mode and other programs are set using commands. If the PMM board fails, only a specialist can repair it. Experience shows that most often the programmer will have to be changed.

The final stage of machine operation

At the end of the cycle, the contaminated liquid goes down the drain. This is followed by a drying stage. It can end in 30 minutes or last more than an hour.

A special signal sent by the device will notify you of the end of the program. The sound volume is adjusted using convenient indicators placed by the manufacturer on the control panel. With their help, you can completely disable the alert function if you plan to load the machine overnight.

When the unit stops completely, press the on/off button. Then the door is opened slightly to allow the dishes to cool faster.

After drying, a high temperature remains inside the unit, so it is not recommended to immediately empty it of its contents. In addition, cookware made from certain materials becomes very fragile when hot.

After the beep sounds indicating the end of the wash, you should wait a while before removing the dishes.

It happens that the cycle is completed, but the dishwasher does not turn off. The most likely cause is an electronic problem. This may also be a consequence of blockage of the drain hole with food debris. The machine cannot shut down correctly.

Program duration for some models

Let's see how the duration of the modes differs for individual PMM models. For this purpose, we will analyze several popular examples of dishwashers of different brands and the duration of washing with these machines.

In practice, different manufacturers set the cycle duration values ​​to be identical. The exact time can be seen in the instructions or on the display (+)

Based on reviews from many users, we can conclude that the most frequently used modes are fast and intensive.

A couple of tips

The “half full” function of the equipment does not mean that in this case the use of water and electricity by this kitchen appliance will be at the optimal level. In most cases, the water consumption of a dishwasher is 60% of the usual amount. The situation is the same with electricity; in addition, overly dirty dishes may simply not be washed.

Systematic and intelligent stacking of dishes will allow you to fill the dishwasher as much as possible. This will make it possible not only to save water and electricity, but also to ensure perfectly clean dishes at the end. Usually, any product comes with instructions with detailed pictures and recommendations on how to lay out kitchen utensils.

It is necessary to take into account that a volumetric dishwasher is more profitable, based on the calculation of water consumption for one full load. But she will use water according to the program, regardless of the number of dirty dishes.

Low noise level

Noise level is one of the important parameters that determine the quality and price segment of modern dishwasher models. Of course, the more expensive the model, the lower the noise level during its operation. Most often, this figure does not exceed 44 dB, and in the most advanced dishwashers the level is no more than 40 dB, which is comparable to the volume of ordinary human speech. In addition, the installation method also plays an important role. A fully built-in model, the body of which is completely located in the niche of the kitchen unit, will be much quieter than a free-standing model located simply on the floor or work surface.

In addition to the operational characteristics of a particular model, the problem of reducing noise levels is also solved using software. For this purpose, special “night modes” are provided, implying a special order of washing stages. You can also turn off the sound signal when the program ends.

How does water consumption depend on washing modes?

Fluid consumption is affected by the presence and use of additional modes. Thus, thanks to “half load”, costs are reduced by 20–30%. Savings are also achieved due to the function of “intelligent assessment” of the load: the device itself decides how much liquid is needed for the cycle in order to wash the dishes efficiently and effectively. Premium models of all types are usually equipped with similar functions - full-size, narrow, compact.

The set of functions and programs for each modification is determined by the manufacturer. The following modes affect water consumption:

1. Economy mode. Wash at 50 degrees. Consumption - 8–9 l.
2. Auto mode. Suitable for both tableware and frying pans. Involves pre-washing, rinsing and drying. Consumption - 6–11 l.
3. Intensive wash. Costs rise to 10–11 liters.
4. Light contamination. Only 7 liters are spent.

How to repair a dishwasher (video)

Whatever malfunction you encounter, remember that you can do repairs yourself only when you clearly know what exactly should be done in a particular situation. Otherwise, you will still have to call professional repairmen, but it is not a fact that the final cost after your actions will remain the same.

Washing dishes in a car is modern, practical, and hygienic. Thanks to the higher temperature of the water and the special agents included in the tablets and powders, no bacteria remain on the dishes. Financial question: should I use tablets or powder? Tablets are multifunctional, but are more expensive. If funds do not allow, use detergent powder, rinse aid and salt.

Those of us who own such a magical household assistant as a dishwasher

, sometimes face her whims. The reasons may be different. If the equipment does not work, you must definitely call a specialist. But there are problems that the hostess can easily cope with on her own. What could be the reasons for this?

A dishwasher is similar in many ways to a washing machine and the problems that arise with it are similar. The most serious ones are scale on the heating element and clogs. In general, this device, with proper use, is designed to last 12 years.

work.

If the dishwasher breaks during operation, plug in an appliance of similar power (a kettle, for example) into the same outlet. If the same thing happens to him, you need an electrician. If the problem is only with the dishwasher, the heating element has probably burned out. Call a specialist.

Ion exchanger with salt - principle of operation and purpose

Some dishwasher owners mistakenly believe that sodium regenerating salt and detergent are the same thing.
However, these compositions perform different functions, and in addition, they are poured into different containers. The powder is poured into a container located in the hatch of the device, salt is added to the reservoir located at the bottom of the washing chamber. Of course, you can find special “tablets” that already contain the required amount of salt. This product is placed in the dishwasher lid reservoir. But if the tap water is too hard and contains a large amount of calcium and magnesium, then it is advisable to use a special salt composition for the ion exchanger. Otherwise, the device will fail quite quickly.

Every dishwasher has an ion exchanger. It contains a resin consisting of sodium chloride. Water intended for washing dishes from the water supply first enters the ion exchanger, where sodium ions replace calcium and magnesium contained in the liquid. This chemical reaction allows you to avoid the formation of scale on machine parts, as well as the appearance of stains on washed dishes.

As the device operates, the sodium salt is gradually washed out of the unit. In this case, it is necessary to use special dishwashing compounds in which the NaCl content exceeds 99% to add a new portion. The use of ordinary table salt is prohibited.

The consumption of sodium salt depends on the operating mode of the machine. Most often it can be configured manually. However, in the future you will have to constantly monitor the composition of the water and, if necessary, make additional adjustments.

You might be wondering: how to choose a dishwasher.

Operating modes

After loading all the dishes, you need to add detergent and rinse aid to the special compartments of the dishwasher. The washing program is selected.

The basic modes for all types of these household appliances are basically the same. They can differ only in name. The standard set of programs is as follows:

1. Soaking or pre-washing should be turned on for heavily soiled items, for example, with burnt food residues.
2. High-intensity washing allows you to wash very dirty and greasy dishes without pre-soaking. Suitable for heat-resistant cookware only.
3. Standard wash is the most common program that effectively cleans dishes with moderate consumption of water and electricity.
4. Economy mode consumes little energy and water. Recommended for lightly soiled items.
5. The quick cycle washes dishes quickly, but does not dry them. This mode will not cope with heavily soiled dishes.
6. Delicate washing is used for glass and crystal products.

How long does it take for a car to wash properly?

The duration of this process depends on several factors, but the main thing is the washing mode you choose. Machine washing of dishes is not much different from hand washing, and it consists of several familiar steps. It often starts with soaking if the dishes are too dirty or you are trying to wash off any remaining grease or burnt food. This is followed by direct washing and rinsing, and this cycle ends with drying. Each of these stages requires its own time, which also depends on the mode you have chosen. In addition, the temperature required for washing according to a particular program plays an important role: the higher it is, the longer the washing process itself will be.

As a rule, one stage of operation of a Bosch dishwasher, as well as devices from many other manufacturers, takes from fifteen minutes to half an hour. Different machines may differ not only in their size and functionality, but also in their washing modes. Today, the work of many manufacturers is aimed at producing units for your kitchen that would cope with a large amount of dishes not only as efficiently as possible, but also quickly enough. If you compare about ten models of dishwashers from different manufacturers at the same time, the average washing time will be about half an hour.

Possibility of embedding

All machines are divided into three types:

• fully built-in (Electrolux ESL 94200 LO, Beko DIS 25010, Bosch SPV25CX01R);
• partially built-in (Electrolux ESF 2300 DW, BBK 45‑DW202D, Bosch SPI25CS00E);
• free-standing (Candy CDP 2L952 W‑07, Hansa ZWM 416 WH, Midea MCFD‑0606).

If you are designing a kitchen from scratch in a new house or apartment, it makes sense to pay attention to the first option. These are dishwashers that can be completely hidden behind the kitchen facade without disturbing the design of the room. If the furniture has been installed for a long time, but you are ready to sacrifice some cabinetry, you can choose a partially built-in machine. As a rule, they are placed under the tabletop: the front panel is visible, but the tabletop on top remains unified. And if the machine cannot be inserted into the existing kitchen set, you can choose a free-standing option, which is often called compact or tabletop.

The location of the machine, as well as the sink, in most cases depends on the connection to the water supply and sewerage system. The closer to the water supply and drainage points, the better.

Water consumption

One of the main questions of the consumer is how much water does a dishwasher consume per cycle? Are the savings really happening?

In the machine, the water is not drained until the end of the work; it only passes through special filters and is returned clean to the top for rinsing the dishes. Additional savings are also generated due to the fact that washing occurs with the help of sprayers, that is, the dishes are washed not with a jet, as with manual washing, but with small splashes. You can reduce water consumption by 20-30% by choosing economical operating modes. It is worth noting that the size of the device does not play a special role.

Pay attention to the level of efficiency before purchasing; as a rule, it is indicated by letters:

1. A, B, C - dishwashers that consume from 9 to 16 liters are called highly economical machines;
2. D, E - machines that use water in a volume of up to 20 liters are classified as average economic;
3. F, G - dishwashers that consume water up to 26 liters per cycle are low-efficiency.

Class A dishwashers not only save water, but are also leaders in minimal energy consumption.

What to look for when purchasing?

Before purchasing, you should know how many dishes you plan to put in the machine; pay attention to the number of baskets for this. The size and type of dishwasher depend on the intended installation location; one buyer prefers built-in appliances, another prefers a tabletop option

Notice how quiet the dishwasher cycle is. The control panel should be clear and convenient

It is better to abandon complex technology if you are unable to disassemble most of the buttons

The control panel should be clear and convenient. It is better to abandon complex technology if you are unable to disassemble most of the buttons.

Entrust the installation and connection of the dishwasher to professionals, this will give you an additional guarantee and confidence in the correct operation of the machine. Ask them to run the machine once in front of you to ensure that the equipment is working properly.

Distinctive features of some dishwasher models

Some dishwashers have distinctive features. For example:

1. Availability of a heat exchanger. This significantly reduces energy costs during drying, but takes time.
2. Availability of a sensor. It determines how clean the water entering the machine is.
3. The presence of a sensor that determines whether there is detergent.
4. The presence of a drying sensor. It determines the level of dryness and humidity of washed dishes.
5. Availability of fasteners for fragile dishes and glasses.
6. Availability of a turbo drying system. It provides ultra-fast drying of dishes.
7. The presence of backlight when opening the door.
8. Durable transparent glass. Used as a decorative element.
9. Projecting on the floor information about the remaining time.

You can additionally wash root vegetables in the dishwasher without using detergent. It is possible to wash various combs, rubber shoes, children's toys, and even cook food by simmering or steaming.

Water saving and other benefits

In addition to significant savings in water resources, modern dishwashers have a lot of other advantages. Firstly, the quality of washing a dishwasher is incomparable to the manual method of cleaning dirty dishes. This is affected by special detergents, as well as high water temperature. After all, an ordinary person will not wash dishes at 75 degrees in a liquid environment. Secondly, it is calculated that a dishwasher saves the owner time in a year, comparable to an employee’s monthly stay at work.

Such kitchen equipment can be successfully used not only for washing dishes. Many owners of modern appliances manage to wash all kinds of gas burners, barbecue grills and even refrigerator shelves in the dishwasher. And only our people could think of effectively using dishwashers to wash potatoes and other vegetables; even rubber boots are used.

Salt indicator

One of the most common causes of malfunctions in any dishwasher is scale. Poor quality of tap water and a large amount of impurities lead to the formation of limescale deposits that settle on the heating element, as well as other internal surfaces of the device. Ultimately, this leads to clogging of the filters, as well as burnout of the heating element. It is in order to soften the effects of hard water that special salt tablets are added to it. Softened water ensures more effective dissolution of detergents, and also eliminates the possibility of white, unsightly stains and deposits on dishes. Salt tablets are loaded into a special container where a sensor is located that determines their remainder. If the salt runs out, the sensor gives a signal and the corresponding indicator lights up on the display or control panel. In this case, it is necessary to replenish the supply of tablets immediately before starting a new wash cycle.

Four main washing programs

Washing and drying cycles range from 0.5 to 2.5 hours. During this time, several sets of cutlery will be washed. You can also wash pots and pans in them. True, you will have to spend your time cleaning the dishes from large leftover food, but at the same time, the rest of the time that would have to be spent on washing the plates will be freed up. The duration of the dishwasher cycle depends on the specified program, which may include:

1. pre-soaking dirty dishes;
2. direct washing;
3. rinsing with or without conditioner;
4. drying.

The cycle in which the dishes are directly washed lasts on average from 15 to 25 minutes, and rinsing lasts the same amount of time. At the end, with a given program, the machine dries the washed dishes. This takes about 20 more minutes.

Often machines have 4 washing modes, that is, 4 programs:

• Quick wash - no pre-wash, program time - 30 minutes. In several models this mode is called rinsing.
• 70 degree mode - long mode - 2 hours 20 minutes, short mode - (Bosch machines have a Time Saving function (Vario Speed) - 1 hour 30 minutes.
• Eco 50 degrees is the most optimal mode, long mode - 2 hours, shortened mode (Vario Speed) - 1 hour 20 minutes.
• Auto - 45-65 degrees - 2 hours 40 minutes.

Bosch dishwasher operating programs.

The fastest program has a low temperature (about 35 degrees). Its duration does not exceed 30 minutes. A regular wash takes 1.5 hours, and the water heats up to 65 degrees. At this time, triple rinsing and drying is started.

An economical program consists of pre-soaking cutlery, washing at a temperature of 50 degrees, rinsing with a double change of water and final drying of the dishes. You will have to wait longer for this program to finish—about 2.5 hours.

Duration of the program (washing) using the example of the Hotpoint-Ariston LTF 11M121 dishwasher.

For the dirtiest dishes, use the automatic intensive wash mode. In this case, the dishes are soaked and then washed at 70 degrees. After this, rinsing occurs four times, and at the end of the regime, the dishes are dried. The duration of such a program is a little more than 2.5 hours.

Some machines, for example, from Bosch, have other modes:

1. Quick wash immediately after eating. The duration of the mode is 30 minutes.
2. Delicate washing of cutlery made of crystal, porcelain or glass at a temperature of 45 degrees.
3. Automatic washing, in which the machine itself determines the degree of soiling of the dishes, calculates the consumption of water and powder, and also programs the cycle duration.
4. The time saving function reduces it by up to half, however, this increases energy consumption.
5. Express mode involves incomplete loading of the machine, in which drying is not provided. The entire washing process takes 15-20 minutes.
6. For example: at 65 degrees in a Bosch SPS 40E42 machine, drying and washing take exactly 1.5 hours.

Having a dishwasher is especially important after celebrations and large feasts. The housewife will not have to wash dirty dishes until late at night. Simply load your appliances onto the racks and come out in the morning clean and sparkling, including pots, pans and baking trays.

The nuances of the dishwasher

If you have just purchased a car, it is better to test run the device. It will help get rid of lubricants that may remain on the product. In addition, this will help check the quality of installation of the dishwasher structure. Check the speed at which the water flows, how it heats up, and whether liquid is spilling out of the device. All problems can be removed at this stage.

In order to carry it out, you need to use a special salt or detergent, which is usually included in the kit. First you need to find out what the hardness of your water is. This will not be difficult for a working Bosch dishwasher. They are equipped with special strips that will help determine water hardness. Just put one of them in the liquid and check it with the plate, which is also included in the kit. Hardness affects what salt consumption should be set in the device.

The salt compartment must be filled completely with water. It needs to be poured there once, just before the test run. In order to place salt in this compartment, you need to use a special watering can. It needs to be visible through the hole. If a little water spills out, it's not a big deal. When you close the compartment with the lid, simply wipe it off.

For the device to operate effectively, you need to acquire a special rinse aid, tablet or powder detergent and salt that softens the water (this is exactly the salt that is needed for a test run). You can buy all of these products separately. But it is better to take ready-made kits from one manufacturer. As a rule, in this case they have components that fit perfectly and complement each other during operation.

How long does it take to wash dishes?

The operating time of the dishwasher depends on which mode you choose and the model of the device. For example, if you choose a program with soaking and pre-rinsing, then be prepared for the unit to work 20 minutes longer. You should select a mode depending on how dirty the dishes are to be washed.

The operating time of the unit is also affected by the temperature of the water required for washing. For example, if you choose a mode that requires water at 70 degrees, you will have to wait another 20 minutes longer. The dishwasher can run from half an hour to three hours.

Here are some of the most popular modes and the time during which you will get clean dishes:

1. The intensive mode is used to wash very dirty dishes using water at a temperature of 70 degrees. The wash lasts 60 minutes.
2. The normal mode involves drying and additional rinsing. In this case, the wash will last 100 minutes.
3. A quick wash is needed to deal with light stains and lasts half an hour.
4. Economy mode is used to save resources and wash standard stains. This mode lasts 120 minutes.

These are the most standard modes. Most devices have many more with additional features. For example, a fairly common additional mode is delicate. It is needed to wash fragile dishes made of crystal, glass or porcelain. As a rule, the duration of operation of the device in this mode is almost two hours. But if you can’t find the names of these modes on the device, then use the temperature as a guide. The mode at 35-45 degrees will work for an hour and a half, at 45-65 degrees - 165 minutes, at 65-75 degrees - 145 minutes, quick wash - a little more than half an hour, pre-rinse - 15 minutes.

Factors that affect wash time

The dishwasher procedure follows the same steps as for manual cleaning. If the dishes are too dirty, pre-soaking is required. After this comes the main stage, rinsing and drying. Each stage of work lasts a certain time in accordance with the selected washing program. The higher the water temperature, the longer it will take to wash dishes. As a result, a full cycle of washing dishes in a machine lasts from 32 minutes to two hours.

Soak

If the dishes are very dirty, there are old stains and dried pieces of food, it is better to use the soaking program. The duration of the procedure is 16-19 minutes.

the washing up

Immediately after soaking (if this function was initially installed), the dishwashing process begins. It assumes the following scheme of work:

• As soon as the household appliance has taken the required amount of water, it begins heating it to the temperature of the specified function. The washing process begins.
• The machine then uses detergent.
• After these steps, water and detergent flow into the spray nozzles located at the top and bottom of the device.
• The sprayers rotate at high speed and supply hot water under pressure to soiled cutlery items that are placed on the shelves.
• After the main washing stage, the dirty water is drained into the sewer, and the next stage begins - rinsing.

On average, a wash cycle lasts 17-24 minutes. If the heating device is in a faulty condition, the machine may not start.

Rinse

This cycle is necessary to get rid of any remaining detergent powder. The cleaning product may be harmful to human health. The rinsing process lasts 18 minutes. Rinse aid is used instead of detergent, and the water does not heat up.

Drying

Many dishwasher models have a drying program. It takes 16-19 minutes for items to dry thoroughly. In cheaper models of dishwashers, a standard type of drying is assumed. Expensive models are equipped with turbo drying. Wet objects are blown with hot air.

Detergents

Liquid dishwashing gel is not needed, because... Dishwashers use completely different chemicals.

As standard, the dishwasher has three compartments for:

• detergent – ​​removes dirt;
• conditioner-rinse aid - prevents clouding and streaks;
• salt – softens tap water and extends the life of equipment.

The detergent comes in the form of a “3 in 1” capsule; such a tablet contains all the necessary components, and when using it, there is no need to add other substances to the compartments. At the same time, manufacturers manage to offer products for dishwashers “5 in 1”, “7 in 1”, “10 in 1”. Usually three main components are enough, the rest are additional substances, additives, and bleaches for specific types of dishes.

Advice! The shortened programs “Half Load” and “Quick Wash”, despite the shortened cycle, dissolve the entire capsule of the detergent component. To save money, you can divide the capsules in half and use half for short programs.

It is necessary to replenish containers with detergents on time and dose the amount of salt based on the hardness of the water. In this case, not food salt, but special technical salt is used.

Attention! There is an opinion that you can use a dishwasher without salt, replacing it with baking soda or soda. In this case, there is a high probability of equipment failure, and repairs may be denied under warranty. Food additives or neglect of operating rules negatively affect the operation of the machine, and white stains may remain on the dishes.

Breakdowns and clogs in the dishwasher

If stains on your dishes after using the dishwasher have become a constant occurrence, then most likely you need to clean them. Yes, yes, like any other household appliance, a dishwasher can get dirty and therefore work worse. In any washing unit, regardless of type and model, there are several places where you should look regularly:

• mesh filter for food debris;
• filling filter;
• sprinklers;
• Heating element and tank.

First, use the owner's manual to locate the food filter in your dishwasher. If your dishwasher doesn't clean well, it's most likely dirty. Usually the filter is located at the bottom of the unit and is a fine mesh. It needs to be cleaned and washed at least once every 10 days.

If you have not very clean and soft water flowing from the pipes in your apartment, then be sure to regularly change the coarse filter core, which is located at the entrance to the dishwasher. If this filter is clogged, the water pressure entering the unit will be significantly weakened. Weak water pressure is another reason why the machine does not wash dishes well and leaves residue on them.

The nozzles, heating element and tank of your assistant may suffer from the presence of limescale, in other words - scale. To prevent this, purchase a special anti-scale agent that matches the type of dishwasher you have. Run it in “idle” mode at least once a month. Use a product that dissolves and washes away scale.

If you notice that your dishwasher is not washing dishes well, take a closer look - the reason may lie in the use of low-quality powder or other detergent. If you recently changed your detergent and began to notice residue and streaks on your mugs and plates, rest assured, this is the reason. It's easy to fix the problem - buy the right product and your dishwasher will clean better.

If you use the same product as before, but the machine begins to wash dishes worse, then perhaps the problem is different:

• on seemingly clean dishes you can see a gray coating and streaks have appeared - there is clearly not enough rinse aid in the water, you need to adjust its consumption;
• the machine does not wash away traces of tea, coffee and lipstick well - the detergent contains little bleach; to improve the result, purchase the appropriate additives or change the detergent;
• For some reason, white streaks remain on the pans - the salt lid is not closed tightly; salt powder gets inside the machine and a white coating is obtained;
• plastic dishes remain greasy - there is not enough fat-dissolving substance; change detergent or add additives manually.

If your dishwasher has started leaving greasy residue and streaks on your plates, remember the last time you used special salt. The reason may be that due to excessively hard water, the ion exchanger has failed and detergents have become poorly soluble in the liquid. Resume using salt and your dishwasher will work better over time.

Leak protection

Any modern household appliances, the functioning of which is connected to a water supply system, is equipped with various leakage protection systems, allowing to avoid serious consequences and expensive repairs. The cause of leaks during operation of the dishwasher can be clogs in the filter elements, breakdown of the pump and inlet valve, as well as errors made during the installation and connection process. That is why most dishwashers are equipped with the AquaStop system, which protects your appliances from the consequences of leaks.

The principle of operation of the AquaStop system is the same for both washing machines and dishwashers. The technology is as simple as possible and at the same time effective. It consists of a special pan with a water level control sensor, as well as a safety valve. When the water level in the pan exceeds the set level, the sensor float rises and closes the contact. From this moment on, the system instantly stops the access of electricity to the safety valve, which allows you to quickly shut off the water supply. The washing program is also paused, after which water begins to drain from the cooking chamber.

There are two main types of leakage protection systems, namely complete and partial. The first option is considered more acceptable due to the presence of a special tank and a float sensor at both ends of the hose. As soon as the signal from the float is triggered, the system automatically blocks the water supply to the faulty dishwasher. As a result, your bathroom or kitchen will not be flooded with water, and the internal elements will not short out due to moisture.

Washing nuances

Many consumers wonder why significant water savings occur when using a dishwasher? The main reason is that modern devices use special technology in the process of washing kitchen utensils. The volume of water already collected from the water supply system is used by dishwashing equipment several times. The liquid solves the following problems:

1. Used for pre-spraying.
2. Washing with special detergents.
3. Rinse.

Having completed one operation, smart equipment does not discharge water into the sewer, but passes it through filters and uses it in the next production cycle. During the process of washing dirty dishes, the liquid is partially drained, and a fresh portion of water comes from the water supply. Thin streams of water under strong pressure are ejected from the sprinklers, which also contributes to significant water savings.

On average, a full cycle of washing and drying kitchen utensils lasts about 2 hours. But if you take into account that with this water consumption a decent amount of dishes are washed, besides, when using 4 - 5 sets, you can wash several pots and pans, which is also a significant plus. An experienced housewife can cope with such a volume in just 30 minutes. On the other hand, even our time on vacation is worth a lot. However, you will still have to spend some time cleaning dirty plates from hard or stuck food debris. But compared to manual washing - insignificant.

Product benefits

Of course, for bachelors, buying miracle equipment may not be such a pressing issue, because there is a lot of advice on the Internet, including putting a disposable plastic bag on a plate. But for at least a small family, purchasing such a product is a real way out of the situation. In addition, a modern dishwasher can significantly save money on the use of water resources.

Consumption

What is the approximate consumption of a dishwasher? Of course, it will be slightly different depending on the brand, model and year of manufacture. But even outdated dishwashers are unlikely to consume more than 20 liters of water. Almost all manufacturers indicate in the technical characteristics of the product the main parameters of water consumption by washing equipment. It is divided, depending on the dimensions, into full-size and narrow. These purchase criteria show how many dishes a particular machine can hold, and how many items it can thoroughly wash in one wash.

13 – 14 regular sets of dishes can bring a full-sized product to shine. The maximum water consumption will not exceed 15 liters. Compact size machines (narrow) capable of processing from 6 to 9 sets. In this case, the equipment will take no more than 10 liters of water from the water supply system.

Saving

And yet, does a dishwasher save our water? According to experiments and consumer reviews, when washing dishes by hand in an amount corresponding to 1 dishwasher load, hot water consumption reaches about 70 liters, and cold water consumes about 30. It turns out that modern household washing equipment can significantly reduce the water supply meter readings.

So how much water exactly does a dishwasher use? Here's an example:

Bosch SPV63M50 (compact) - loading up to 9 sets, consumption 8 l;

Siemens SN66M094 (regular) - loading up to 14 sets, consumption 10 l;

Smeg BLV2VE (full size) - 13 rooms, 8.5 l.

For a small family and pensioners, a compact model is quite enough, otherwise you will have to spend excess water on washing just a few plates and you won’t be able to save money. Or, as an option, long-term accumulation of dishes to fully load the machine. The leaders in terms of savings at this stage are European brands. It is these machines that should be given preference if the factor of saving water resources is significant for the consumer

Well-known brands such as Electrolux, Bosch, Siemens pay special attention not only to saving tap water, but also electricity

The models presented in the example are premium products. The average power consumption ranges from 0.7 to 0.9 kW, depending on the size of the equipment. Many modern models have a half-load function; its use allows you to save up to 30% of water. The undoubted leader, according to consumer reviews, constantly tops the list of the best dishwashers, is Bosch.

Half load

When purchasing a dishwasher, be prepared to increase the number of dishes in your home. 10-12 sets is quite an impressive amount, and it is recommended to load the device completely. Therefore, for each meal you will need a new set of dishes. The dirty one, meanwhile, goes to the dishwasher, where it waits in the wings.

However, there are situations when there is no time to wait until the required amount of dishes accumulates. For example, if you have a holiday and you need to refresh the plates before the next change of dishes. Or you are categorically against long-term storage of dirty dishes. For such cases, some dishwasher models have a half-load function. It can be used in any washing mode.

Half loading has several advantages. You can wash dishes without waiting for the required amount to be collected. This saves water, which requires less, and electricity for heating it. But, unfortunately, the savings will not be 50%, as many hope, but about 20-30%.

This mode is present in most models of the middle and high price categories. Of course, even if there is no half-load function, you can run the machine to wash several dishes, but in this case there can be no talk of any savings.

In some expensive models, manufacturers replaced the half mode by installing special sensors. They are able to determine the weight of loaded dishes and the degree of contamination, calculating the required resource costs.

Is a half load necessary in a dishwasher? If you have a small family and you are not used to putting off washing dishes “for later,” then it will bring a lot of benefits. But if you are used to loading the dishwasher to the top, the option will most likely remain unclaimed.

The “1/2” function also has some disadvantages. For example, dishwasher tablets are designed for a full cycle, and not for a shortened program, so they often do not have time to completely dissolve. In order not to waste an expensive product, it is recommended to dose the amount manually by cutting the tablet. Do this with a sharp knife so that it does not crumble - its components should fall into the water in stages.

When the dishwasher is half loaded, the correct placement of the dishes is of great importance. For each model, the manufacturer defines its own rules. They are described in the instructions for the device. In some machines you only need to load the upper basket, in others - the lower one. Sometimes devices have to be distributed evenly at all levels. It is necessary to provide maximum free space between containers to improve the quality of washing.

It is recommended that large cutlery (spatulas, ladles, whisks, etc.) be placed crosswise horizontally in the front of the basket. Spoons and forks are placed in a vertical position. To prevent fragile glasses or glasses from breaking during washing, they should not come into contact with each other. It is better to place large containers evenly throughout the entire volume of the baskets.

Rule No. 2 – choose the right washing mode

A standard dishwasher cycle includes pre-wash (rinsing off food residues with cold water), wash (directly washing with hot water using detergent), rinse (rinsing off detergent) and drying.

In addition, in dishwashers there are such programs as intensive washing (very high tº - up to 75 degrees), a program for fragile dishes (water tº - from 30 to 40 degrees), quick wash (when you need to rinse the dishes after liquid food and immediately after meals) and others.

In addition, dishwashers of the middle and highest price categories have a “pre-soak” function. But it is much easier and more economical to manually clean off dried-on food residues from them before loading the plates into the machine. The same thing with “burnt” pots and pans.

What items can be washed in a dishwasher?

Ceramic and metal objects can be washed in any mode. Aluminum is a rather capricious substance and contact with hot water and substances used for washing dishes can have a detrimental effect on it. In this case, there is a high probability of corrosion stains appearing. We strongly do not recommend washing aluminum spoons, pots, plates and meat grinders in the dishwasher, since in this case there is a high probability of dark spots appearing on the surface of the dishes. After this, the use of utensils becomes harmful - aluminum particles entering the body have a detrimental effect on internal organs.

If you do wash your aluminum cookware in the dishwasher and find dark spots, it’s time to treat it. Any means will do here: from toothpaste to rust solvent. The safest way is to keep the dishes in a soapy solution. Add a few drops of liquid tar soap to warm, but not boiling, water. Afterwards, dip the darkened objects into the solution. There's no time limit here, so you don't have to worry about adding too little or too much soap to the water.

The method of rubbing with soda is no less popular. A thin layer of baking soda is applied to the damp surface and, after half a minute, you can begin to rub. Remember: under no circumstances boil dishes in a soda solution. This can only worsen the condition of aluminum cookware and accelerate the processes of oxidation and corrosion.

Therefore, to avoid such situations, it is better to wash aluminum items by hand. It may take you some time, but you can avoid corrosion and extend the life of your cookware.
