We need a parameter in kW/h, which determines the economic class of the device.
Washing machine efficiency classes
How much power your washing machine consumes depends on what class of electricity consumption she refers to.
All devices are designated using Latin letters from A to G. For example, the letter "A++" means that this is the most energy-efficient model.
Typically, this information is affixed to the appliance body. You can also find complete information about a specific household model on the manufacturer's official website. For example, power information Samsung washing machine can be found on the Samsung website.
When assigning a washing machine a particular energy consumption class, special laboratory tests are carried out.

Based on the experiment, the unit is assigned the appropriate class:
- “A++” is the minimum energy consumption of 0.15 kW/h per kg of laundry;
- class “A+” has a slightly higher electricity consumption than “A++” – 0.15 – 0.17;
- the average type is considered to be “A”, which consumes from 0.17 to 0.19 kilowatts;
- marking "B" - within 0.19-0.23;
- class "C" device consumes 0.23-0.27;
- a car with the letter "D" under the same conditions consumes electricity from 0.27 to 0.31.
Washing machines marked E, F, and G are no longer produced. They are very energy-intensive, consuming over 0.31 kilowatts per hour per kilogram of laundry.
What does the power of a washing machine depend on?
The power consumption of a washing machine consists of the energy consumed by its main components:
Engine twists drumThe higher the RPM, the higher the fuel consumption. Furthermore, engines come in several types:
- asynchronous with a power of no more than 400 watts, which are no longer used today, but in the old unit, it is quite possible that this is the type of motor installed;
- All new models operate on collector and inverter motors, which consume up to 800 watts depending on the wash cycle selected.
Consumes the most energy heating element, it is he who heats the water to the desired temperature. Power heating element is equal to 2.9 kW.
Another energy-consuming part of the washing machine is pump, which pumps out water several times during the wash and rinse cycles. The device consumes up to 5 watts when operated mechanically, and if your washing machine has an electronic display, the consumption doubles.
Is the power of appliances the only factor that affects electricity consumption? Of course not. Program selection, washing modes, drum load, and even the condition of the appliance's components can also play a role.
When purchasing a washing machine, please pay attention to:
top-loading equipment linen is more economical due to its small dimensions, but it is also suitable for a small family;
- If a spacious drum is important to you, then you should study all the models with a large drum and choose the one with the most economical class;
- When choosing dimensions, focus on the laundry load capacity that will ultimately satisfy your needs. For example, compact machines with a depth of 40 cm and a laundry load of 4.5 kg are already being produced, with a washing power consumption class of "A".
What else does the electrical power of a washing machine depend on?
The choice of washing mode directly affects energy consumption. Consumption increases with temperature. heating water, washing duration, rinsing time, drum speed during spinning, additional functions.
- Washing polyester requires much less energy than washing cotton and linen. Furthermore, these fabrics differ significantly in dry and wet weight.
- The more the tank is loaded, the higher the electricity consumption.
How much does washing machine power cost in kW?
Modern washing machines consume on average between 0.5 and 4.0 kilowatts. Class A appliances are the most common due to their excellent combination of quality and affordability, consuming between 1.0 and 1.5 kW. A higher class, such as A++, will cost significantly more.


Let's assume an average of 60 liters of water per wash, three loads per week, and living in Moscow or the surrounding region. The result is as follows: washing during the day will cost 166 rubles per month, while washing at night will cost no more than 57 rubles.
Most likely, if you live not in the capital, but in the regions, then the cost of the electricity you consume is significantly lower.
So, when buying a washing machine, pay attention not only to its size, design, load capacity, and wash programs, but also to its class and power consumption. This will allow you to use your washing machine wisely and save on utility bills.
For comparison, let's look at how much electricity is needed to operate other household appliances:
- The hob consumes 1 to 2 kilowatts per hour.
- A kitchen hood uses between 0.12 and 0.24 kilowatts per hour.
- A water heater up to 150 liters will consume approximately 6 kW.
- Domestic air conditioner operates in the range of 0.4 – 0.24 kW.
- A microwave oven consumes 0.6 – 2 kW.
- Mixer - about 0.2 kW.
- A household vacuum cleaner uses about 1 kilowatt per hour.
- The clothes drying machine consumes 2-3 kW.
- A stationary computer consumes from 0.3 to 1 kW.
- Dishwasher – approximately 3 kW.
- A typical TV uses 0.15 kW.
- The iron consumes 1 kW.
- The refrigerator is only 0.2 kW.
- An electric stove consumes between 3-8 kW.
- An electric grill uses 1-3.6 kW.
- The toaster consumes 0.8-1.5 kW.
- Pressure cooker – from 1 to 2 kilowatts.
- Built-in oven – from 2 to 5 kW.
- The coffee machine uses from 0.5 to 1 kW.
- Water heater (flow-through) – approximately 3.5 kW.
- The freezer consumes 0.2 kW.
