Pros and cons of an inverter motor in a dishwasher
The device has a number of differences and disadvantages from a standard electric motor. The advantages of the motor include:
- saving electricity;
- long engine life;
- automatic determination of energy consumption depending on the load on the machine;
- noiselessness.
In addition to the advantages, dishwashers with an inverter motor also have a number of disadvantages:
- The high cost of equipment, as well as expensive engine repairs if it breaks down.
- Maintaining constant voltage in the network. If changed, the electric motor does not work or quickly fails.
- Limited selection.
The motor was invented in Korea for air conditioners and microwave ovens in order to save energy resources. Nowadays such a device is found not only in dishwashers, but also in washing machines and refrigerators.
PROCESS CONTROL
95% of modern dishwashers are electronically controlled. The user sets the required program by pressing the appropriate buttons to set one or another mode and enable additional functions. Models with touch controls (Samsung DMM 39 AHC) are extremely rare.
Machines with electronic control are equipped with a display that displays information about the program’s operation and the time remaining until the wash is completed. Also, information about errors may appear there if there is a malfunction (if the machine has a self-diagnosis function).
Naturally, all the operating features of the device are reported by the indication.
Indicators inform you about the selected program, its progress and the time until its end. They control the consumption of salt and rinse aid, and report the end of these products.
The Floor Beam indicator is only used on fully built-in models. Found in AEG F 88400 VI, Electrolux ESL 4300 RO, Zanussi ZDV 15001 FA, Zigmund & Shtain DW89.4503X, BEKO DIS 5630 and many others.
Some models are so quiet that only the LED indicator can indicate the end of the program. The same task - to inform about the end of work - is solved by a sound signal, which can be turned off, for example, like in the Miele G 4760 SCVi, if the machine is working at night or the noise in the apartment is undesirable. According to the Holodilnik.ru consultant, the sound signal can be turned off in any car that has it, and this can be done according to the instructions when installing the equipment. This feature is a valid factory setting. But there is no special button on the remote control.
Rating of the best models
Without a doubt, Bosch is considered the best and most reliable company. Non-built-in and built-in dishwashers with inverter motors are distinguished by their reliability, capacity and cleaning quality. The only drawback of this equipment is its price, which includes not only the cost of the dishwasher itself and the markup of sellers, but also the overpayment for the brand itself. Therefore, below is a rating of budget and reliable dishwashers that are not inferior in quality to Beauchamps.
The choice of dishwashers with inverter motors in large stores across the country is not so wide. Representatives of Polish companies are considered identical in their functionality and characteristics: Electrolux, Indesit, Hotpoint-Ariston, Whirlpool. The equipment warranty is 1 year.
The cars are practically no different. Some of them have a special compartment for cutlery, automatic door opening, and complete protection against leaks. Additional features increase the price.
The rating is based on dishwashers in the price range not exceeding 35,000 rubles:
Disadvantages of this PMM: lack of complete protection against leaks, it does not dry well enough. Moreover, this drawback is found in almost all machines from this company.
The machine has additional functions, such as automatic door opening, full protection against leaks, and an enhanced washing mode. The remaining characteristics are similar to other representatives at an affordable price.
Fully recessed or simply recessed
The difference is simple: a fully built-in dishwasher is covered on the front side with a furniture panel and looks like another kitchen cabinet. The control panel of such machines is located on the edge of the hinged door. Fully built-in models include Siemens SR 66T090, Hotpoint-Ariston LST 1149, Whirpool ADG 145. For partially built-in models, the control panel located on the external panel remains partially open, like Smeg PLA4525X, Kaiser S 45 U 71 XL, Bomann GSPE 774.1, Miele G 4700 SCi.
A special feature of built-in dishwashers is the use of a metal plate on the countertop to protect against steam.
The number of companies producing dishwashers of this size is huge. These are well-known brands: Miele, Bosch, Neff, AEG, Zanussi, Whirlpool, Indesit, Candy, Flavia, Wader, Korting, Ilvito. There will be a dozen more names.
Some manufacturers offer either only built-in equipment, or only free-standing machines. But the majority is trying to bring to the market such a variety of both models, so that any buyer’s request can be satisfied. Remember, like Raikin:
– White top, black bottom?
– Black top, white bottom?
Inverter motor in a dishwasher
There are many models of dishwashers from different manufacturers on the modern market. Not least important is equipment with an inverter motor. What is the difference between a conventional motor and innovative technology, we will find out in this article.
A LITTLE ABOUT PRICE
It is worth noting the fact that the presence of a heat exchanger in the car does not affect the average cost of the equipment. Increasing the number of cookware sets from 9 to 10 increases its cost by $70. The higher the noise level and parameters of water and electricity consumption, the fewer the number of programs and additional functions, the simpler the start timer and the internal organization of the space of the dishwasher, the cheaper it is.
Under equal conditions, narrow cars are cheaper than full-size ones by an average of 3,000-7,000 rubles.
What it is?
A modern premium dishwasher will most likely have an inverter motor. If you go back to your school physics course, it will become clear that such a motor is capable of converting direct current into alternating current. At the same time, a change in the voltage indicator occurs. There is no usual noise that is typical for cheaper built-in dishwashers.
Drying dishes
Drying dishes after washing can also be considered a very important option, which should be present in any standard machine. Typically, this mode is carried out in several ways and involves two technologies:
- hygienic condensation drying, in which all devices are rinsed with very hot water, after which it evaporates from their surface;
- active turbo drying, which gives better results due to the presence of a fan inside the device body.
The first option is typical for inexpensive models; it uses less resources, but takes more time. The second type of drying option can most often be seen in expensive devices, and it requires greater power consumption.
Advantages and disadvantages
When talking about such an innovative technology, one cannot help but touch on the existing advantages and disadvantages.
The following indicators stand out among the advantages:
- saving;
- long service life of equipment;
- the machine automatically determines the required energy consumption;
- no noise during operation.
But inverter-type motors also have some disadvantages:
- the cost of such equipment is much higher, however, the user will have to pay more for repairs;
- the network will need to maintain a constant voltage - if this condition is not met, then the equipment stops functioning normally or even breaks down quickly;
- the choice is strictly limited.
At the very beginning of development, this type of motor began to be widely used in the design of microwave ovens and air conditioners. This is exactly how they tried to solve the problem of saving energy resources.
Tips for choosing
- The best option for a small family and a small kitchen is a narrow or small-sized model with a load of 6 sets of dishes. For example, the budget Electrolux ESF 2400 OW or the middle class Siemens SK 76M544;
- For those who like to receive guests and large families, it is worth taking a closer look at devices with a capacity of 10 sets or more. Asko D 5436 W will be an excellent solution;
- Pay attention to the presence of energy- and water-saving parameters and functions that increase safety;
- If ease of use is your first priority, it is better to give preference to a partially built-in installation; if you prefer aesthetics, choose a fully built-in one;
- If you have a variety of or expensive dishes, you need to take care of a large number of programs, including a delicate washing mode.

How is it different from usual?
The standard motor in a dishwasher runs at the same speed. In this case, the load level is not taken into account by the equipment. Accordingly, even with a minimal amount of dishes, the same amount of energy is consumed as with a full load.
The inverter regulates the operating speed and energy consumption, taking into account the described indicator. Depending on how loaded the equipment is, the optimal operating mode is automatically selected using a sensor. Thus, there is no waste of electricity.
On the other hand, conventional engines, in which gears and belts are installed, produce a lot of noise. Despite the fact that the inverter motor is larger in size, it is quieter because it has no moving parts.
Household appliances with this type of motor are now actively supplied to the market by LG, Samsung, Midea, IFB, Whirlpool and Bosch.
CUTE OPTIONS
Additional features always add to the attractiveness of a technology.
Thus, the VarioSpeed Plus function in some models from Bosch, NEFF, Siemens allows you to wash and dry dishes twice as fast and even with a full load, maintain washing and drying classes. The function is included in addition to almost any washing program, except for pre-rinse and quick wash. When large quantities of dishes need to be washed quickly, such as after family meals, VarioSpeed Plus reduces dishwasher runtime by 65% without compromising cleanliness and drying quality. Built-in dishwasher 45 cm Siemens SR65M081RU, Siemens SR 65M035, built-in Neff (S58M43X1RU)
The IntensiveZone function allows you to wash heavily soiled pots and pans in the lower basket, while at the same time washing less soiled dishes and dishes that require delicate care in the upper basket. This is made possible by new technology that supplies water to the lower basket at a higher pressure and temperature than the upper basket, as well as additional cycles.
The Hygiene Plus function ensures disinfection by rinsing dishes with 70°C water for 10 minutes. Ideal for families with small children and people with allergies.
The half-load function is present on every second machine (Hansa ZIM 436 EH, Indesit DSG 573, Flavia BI 45 IVELA Light, Zigmund & Shtain DW69.4508X). In this case, one of the two dish baskets is loaded. This is taken into account by the machine’s sensors and is reflected in the consumption of water, detergents and electricity. But time is not saved. For some machines, the Economy program is an alternative to this function.
Rating of models with inverter motor
The rating of inverter built-in dishwashers includes not only full-size ones, but also models with a cabinet width of 45 cm.
Bosch Serie 8 SMI88TS00R
This model features 8 basic dishwashing programs and has 5 additional functions. Even when fully loaded, the plates are perfectly clean.
There is an AquaSensor - a sensor that is designed to determine the level of contamination at the beginning of the cycle. Subsequently, it sets the optimal time required to wash dishes. If necessary, starts pre-cleaning.
The chamber holds up to 14 complete sets. Water consumption is 9.5 liters - this is how much is required for one cycle. If necessary, half load mode is started.
The design of the unit has an inverter motor. The equipment operates almost silently. There is a display on the panel and the ability to activate parental controls.
Advantages:
- you can postpone washing for the required time;
- easily recognizes the cleaning agent used;
- there is a built-in shelf where espresso cups are placed;
- You can activate the self-cleaning program.
- fingerprints remain permanently on the touchpad;
- the cost is not available to every user.
Electrolux ESF9552LOW
Non-built-in appliances with the ability to load 13 sets of dishes. After the end of the cycle, this model opens the door on its own. There are 6 operating modes, delayed start can be activated.
There is a small mesh inside for cutlery. The basket can be adjusted in height if necessary. The manufacturer has installed a special sensor in the design of the model, which determines the required consumption of water and electricity.
Additional benefits:
- water flow is regulated automatically;
- There is an indicator for determining the detergent.
- The dimensions are too large, so it can be difficult to find a place for equipment.
WASH EVERYTHING
The vast majority of machines are equipped with 5-6 washing programs. Their main set is: Automatic, Normal, Economy, Fast and Pre-soak/Rinse. This type of wash, such as Delicate, is not available on all cars.
The programs may include a Bioprogram, which uses special bioadditives that are part of modern detergents. Dietary additives quickly break down and remove fat, as well as protein contaminants, and are able to work only at low temperatures, which means that the dishwashing program in this case should be low temperature.
The automated dishwashing mode allows the machine to select the optimal washing option; you just need to indicate the degree of soiling of the dishes. But many modern models determine the amount of dishes and the degree of contamination automatically using special sensors. So the loading sensor allows you to set a more economical option for the amount of water for the loaded amount of dishes.
Smart Bosch machines use sensors to recognize the degree of water contamination (AquaSensor), while saving both water and energy. 2/3 of the dishwasher market is equipped with similar sensors.
Economy mode with a temperature of 50-55 °C is suitable for medium and lightly soiled dishes, which will save 20% of resources.
Quick wash is used for lightly soiled dishes and lasts for 30 minutes. Candy CDP 4709, for example, calls it this: “Ultra Fast 24 min. 50°C.” Informative.
The pre-rinse mode consists of rinsing the dishes with cold water and, thanks to the seal of the dishwasher, remaining wet for a long time. The rinse can be used each time a new batch of dishes is added to prevent food residue from sticking to the plates until there are enough dishes to wash.
