How to choose the optimal power for your dishwasher

Many buyers, when choosing equipment, do not pay attention to the power consumption of the dishwasher (hereinafter also referred to as PMM, dishwasher). They are more interested in the version of the PMM (built-in, free-standing or tabletop), the design and the number of dishes that the device can wash at one time.

The energy efficiency of large household appliances is improving year after year.

The electricity consumption of a dishwasher is one of the important characteristics that must be taken into account when purchasing a PMM, since utility tariffs are increasing from year to year.

Power and energy consumption: what's the difference?

Most people confuse these two indicators. In fact, there is a big difference between them. Energy consumption is the amount of energy that the dishwasher uses in one hour of operation . At the same time, individual parts of the PMM do not work continuously during this time.

For example, a tubular electric heater (hereinafter also referred to as a heating element) turns off after heating the water to the desired temperature. This will take him, for example, 10 to 15 minutes. The drain pump runs for a maximum of half an hour. At different stages of the operating cycle, different PMM nodes are involved, therefore the average energy consumption per hour of operation is determined. The calculation is carried out in kilowatt-hours (kW/h).

The energy consumption level is divided into classes - from A to G

Power is the amount of energy that the dishwasher takes from the electrical network in the event of simultaneous operation of all its components . How much electricity does a dishwasher use compared to its power? It turns out that the difference between the PMM power indicator and the energy consumption is very significant. Power is 2-3 times higher than the level of energy consumption, and its unit of measurement - kilowatt (kW) - is not tied to time . The cross-section of the electrical cable supplying electricity to the device depends precisely on the power that the dishwasher has.

Let's calculate the consumption of electricity and water

We have figured out the approximate characteristics of dishwashers, now let's do the calculations and calculate how much you will have to pay for water and electricity when using the dishwasher.

To calculate, we take the average figures for 1 kilowatt of electricity = 4 rubles. For 1 cube of cold water = 15 rubles. (mostly this is a number from 10 to 30 rubles in Russia). Let's take into account that the sink will be turned on daily.

For 1 dishwashing cycle we spend:

Dishwashers for 6 sets: For electricity - 0.62 * 4 = 2 rubles. 48 kopecks For water - 0.008 * 15 rub. = 12 kopecks Total: 2 rub. 60 kopecks

Dishwashers for 9-12 sets: For electricity - 0.95 * 4 = 3 rubles. 80 kop. For water - 0.01 * 15 rub. = 15 kopecks Total: 3 rub. 95 kopecks

For 1 month of use:

Dishwashers for 6 sets: 0.62*30 = 18.6 kW (kilowatt for 1 month) 0.008*30 = 0.24 cubic meters of water for 1 month For electricity - 18.6 * 4 = 74 rubles. 40 kopecks For water - 0.24 * 15 rubles. = 3 rub. 60 kopecks Total: 78 rubles

Dishwashers for 9-12 sets: 0.95 * 30 = 28.5 kW (kilowatt for 1 month) 0.01 * 30 = 0.3 cubic meters of water for 1 month For electricity - 28.5 * 4 = 114 rubles. For water - 0.3 * 15 rubles. = 4 rub. 50 kopecks Total: 118 rubles 50 kopecks

For 1 year of use:

Dishwashers for 6 sets: 0.62*365 = 226.3 kW (kilowatts for 1 year) 0.008*365 = 2.92 cubic meters of water for 1 year For electricity - 226.3 * 4 = 905 rubles. 20 kopecks For water - 2.92 * 15 rubles. = 43 rub. 80 kop. Total: 949 rubles

Dishwashers for 9-12 sets: 0.95*365 = 346.75 kW (kilowatt for 1 year) 0.01*365 = 3.65 cubic meters of water for 1 year For electricity - 346.75 * 4 = 1387 rubles. For water - 3.65 * 15 rubles. = 54 rub. 75 kop. Total: 1441 rubles 75 kopecks.

Electricity consumption classification

PMMs are classified not by power, but by energy consumption. All large household appliances have labels that indicate the level of energy efficiency of models of various brands - Bosch, Siemens, Electrolux and many others. The information on the tags of almost all products is systematized in the same way (see figure).

The sticker contains comprehensive information about the technical characteristics and operating efficiency of dishwashers

Interesting fact: such an indicator as power is not on the tags. There are energy efficiency classes. The most energy-efficient products are assigned classes A+++, A++, A+, and A.

Depending on the class, electricity consumption increases as follows:

• A+++ – 0.63 kW/h and less;
• A++ – from 0.65 to 0.75 kW/h;
• A+ – from 0.75 to 0.85 kW/h;
• A – from 0.85 to 1.05 kW/h;
• B – around 1.05–1.2 kW/h;
• C – in the range of 1.2–1.5 kW/h;
• D, E – from 1.5 to 2.3 kW/h.

Information about classes F and G is no longer relevant today. Most buyers choose products with classes from A to A+++.

The power of household appliances is the main criterion for its selection. A decrease in indicator does not always cause a decrease in efficiency and functionality. Manufacturers are constantly working to develop energy saving technologies. The use of these methods allows you to reduce energy costs.

What components and parts affect energy consumption?

Each dishwasher consists of a certain set of components and parts. They all consume a certain amount of energy. The level of its consumption depends on the following components:

1. The heating element is the most energy-consuming element. The power of this device that heats water for washing dishes varies widely and can exceed 2 kW. Its operating time depends on the water temperature level that is set in the selected program. The temperature range is quite wide - from +30...35 ℃ to +70...80 ℃. PMM models with forced drying have another heater that increases the air temperature, as well as a fan. Unlike devices with convection drying, such dishwashers have a higher energy consumption level.
2. Circulation pump - pumps liquid into the nozzles of the spray arms, and also ensures the reuse of water in order to save it. The power of this pump is low, approximately 100 W. The longer the dishwashing program lasts, the more energy the appliance consumes.
3. Drain pump - pushes waste fluid into the sewer. Pump power – from 30 to 40 W. The duration of its operation depends on the amount of dirty water that needs to be removed from the PMM.

Dishwasher drain and circulation pumps (bottom view)

Energy consumption indicators depend on several other factors:

1. The amount of liquid consumed per washing cycle. The indicator ranges from 7-15 liters. The more water, the longer it needs to be heated. The operating time of the drain pump also depends on the volume of water.
2. Duration of the washing process. The time depends on the program selected by the user and varies widely - from 40 minutes to 4 hours. This indicator affects the total energy consumption of the circulation pump.
3. Basket sizes. This indicator determines the number of tableware that can be washed in one cycle, and affects all others. If we compare narrow and full-size PMMs, the latter will require more water to operate, as well as a more powerful electric heater and pump for sprinklers. The units of small tabletop dishwashers have the lowest energy consumption and power.

The countertop dishwasher is the least productive, but the most economical of all types of PMM

How else can you save on utility bills?

It is also possible to save energy consumed by PM under certain operating conditions. Below are tips to help you reduce your costs.

• Electricity tariffs in some regions may vary depending on the time of day. If you wash dishes at night, you will pay less for electricity at the end of the month. Buy dishwashers with a “delayed start” function, which will allow the appliance to start working on its own at the right time.
• Take care of your equipment regularly: clean the heating elements from scale. Deposits on the heating elements cause the dishwasher to spend more energy heating.
• Pre-soak dishes with dried mud.
• If the dishes are not very dirty, then wash them in the machine at a temperature of 300. This is quite enough to wash off food residues and at the same time save a lot of energy on heating water.
• Buy a PM with a built-in heat exchanger - a container that allows you to save thermal energy inside the machine itself and heat the water faster the next time you start it.
• Don't start PM for the sake of two or three plates or mugs. Accumulate dirty dishes, soak them in the machine before washing them, and then wash them as a whole set. In this regard, dishwashers with a half-load mode are very convenient, which allows you to spend electricity and water for washing dishes in proportion to the amount inside. In models without this function, the amount of dishes loaded into the chamber will not matter: the same amount of water and electricity will be consumed as with a full load.

Useful tips for using dishwashers

If you properly allocate resources and operating time of the dishwasher, you can save energy. Follow the recommendations below:

1. Wash dishes at night when electricity rates are lower. To do this, you need to have a two-tariff electric meter and a PMM, which has a delayed start function. In the evening, turn on the device, select a washing program, start it and wait until the water in the tank finishes filling. Then stop the program and enable delayed start. Firstly, in the time before restarting, the water will have time to warm up to room temperature and less energy will be needed to heat it up. Secondly, the work cycle will be performed at night, when the electricity tariff is lower.
2. Don't keep dishes dirty for too long , as dried food waste makes them more difficult to clean. You will have to run a program with soaking, double rinsing and washing at a higher temperature. Naturally, such a choice will lead to more energy consumed.
3. Choose your washing program wisely - do not wash slightly soiled dishes with hot water for too long. For effective cleaning, an accelerated mode at a liquid temperature of +30...40 ℃ may be sufficient.
4. Try to load the dishwasher as much as possible . Running a partially loaded PMM is impractical due to inefficient use of electricity. But if your model has a half-load function, use it.
5. Regularly descale the heating element of your dishwasher. If the heater is covered with a layer of scale, it heats the water much worse, while consuming the same power as before.

Today, stores offer a wide selection of dishwashers for any family. When choosing, be sure to pay attention to energy efficiency rating labels - this will save you from unnecessary costs when paying bills in the future. You will find tips on choosing dishwashing equipment in our other article.

Saving tips

To save on using a dishwasher, you should:

1. Select a program that has a delayed start. Some models provide half loading. This way you can reduce water consumption by 30%.
2. Use a heat exchanger. In this case, costs are reduced by 20%.
3. Clean the heating element from scale. This should be done once every two weeks. It can be done more often if plaque accumulates quickly. Mineral deposits reduce heating efficiency. The device operates at high speed and consumes a lot of energy. You can use special filters that reduce hardness. After all, if you use the device with scale inside, its service life will be shortened.
4. Choose economical modes. This applies to cases where you need to wash a small amount of dishes. Then less water and energy are consumed.
