It is difficult to surprise a modern consumer with a wide selection of dishwashers, and everyone chooses a product for themselves based on various technical characteristics. One of the main ones is the power consumption of the dishwasher. If for most household products high power is an indicator of the increased efficiency of the device, then for dishwashers this is more a minus than a plus. Low-power kitchen units consume less energy, so potential customers are in prime demand.
Cost-effectiveness indicators
The saving factor for a particular dishwasher is determined by the energy efficiency of its working elements, and the engineering know-how that the manufacturer introduced in this model. The main electricity is distributed between the heating element, the circulation pump and the pump. The leader is the heating element, which heats the water, in the second position - the heater, which is responsible for drying dishes. Machines without a drying function, respectively, have significantly lower power consumption.

Dishwasher Classification
When buying a model, you need to keep in mind the performance characteristics of the model, in particular, the class of "energy consumption", which is indicated by the letter of the Latin alphabet.
- Class A. The electricity that these machines consume ranges from 0.7 to 1.07 kW.
- Letter B. Energy consumption from 0.8 to 1.1 kW.
- Class C - up to 1.5 kW.
- D and E - up to 2 kW.
- F and G (the most inefficient obsolete models - range from 2.5 to 2.7 kW).
Those manufacturers who managed to achieve an electricity consumption of less than 0.7 kW, then usually the letter A is accompanied by an additional “+” sign. The more advantages, the greater the energy efficiency of the model.
The energy consumption of cars depends on the volume of the tank and the temperature of the water. It is clear that the smaller the tank capacity, the lower the power consumption. Some manufacturers, such as Bosch, equip some models with heat exchangers. Their use allows you to qualitatively wash the dishes of a large volume and quantity. Energy consumption is minimal.
Heat exchanger advantages
The main functions of the innovative element used in modern models:
- When using the heat exchanger in dishwashers, water slowly cools. As a result - the absence of temperature differences and reduced load on the working elements of the machine.
- Warm water heated in the heat exchanger is used by the machine in the final mode when rinsing. This means that you can significantly save on heating the last portion of water.
- Waste hot water, which is discharged by ordinary dishwashers, can damage the sewer. When using a heat exchanger, the water gradually cools, and not a boiling, but a warm liquid is removed.
A heat exchanger is also used to dry dishes. Technological engineers found that in models equipped with this element, the drying efficiency increases by 1.5 times. However, it should be noted that kitchen units with a heat exchanger have a high price range, although during operation, the initial costs pay off over time, because such machines consume significantly less energy.
Ways to save money when using dishwashers
To achieve the greatest efficiency and reduce the amount of energy consumed, it is better to decide on the choice of model in advance, but in addition there are the following recommendations:
- Manually remove food debris so that it does not dry onto the dishes; in the case of dirt sticking, much more energy will be required to clean it.
- Give preference to models with a built-in heat exchanger.
- You should not start the machine to wash a couple of plates or cups. Pre-accumulate the dishes, and then turn on the dishwasher.
- Follow the instructions, correctly put the kitchen utensils in the washing bowl.
- Descale in a timely manner. A heating element with a buildup spends significantly more electricity than a pure heating element.

An overview of economical models
Significant power of the dishwasher threatens high kW consumption. What needs to be done in order to reduce energy consumption without sacrificing the quality of drying and washing dishes? Each user asks how much electricity the dishwasher consumes in each case.
A brief overview of some models.
- The dishwasher of the Bosch SMV 59T10 brand is equipped with a heat exchanger. This element is already the second generation more advanced. The manufacturer guarantees full protection against leaks, even in case of serious malfunctions, you can not worry about your property. The quality of washing and drying corresponds to the premium class. In addition, the Bosch SMV 59T10 unit is able to efficiently wash 13 sets of dishes at the same time, equipped with a digital screen, a load sensor and touch-sensitive control keys. A significant plus is the presence of the child lock function.
- Built-in dishwasher Bosch SPV69X10. A feature of this machine is that it is not full-sized, but narrow. However, with dimensions 82 * 45 * 55 in terms of its technical parameters, it practically corresponds to the previous model SMV 59T10. This machine is equipped with the express wash program, which is in demand and popular with consumers.
- The full-size built-in dishwasher Zigmunt & Shtain DW6009X is capable of washing 15 sets of dishes, equipped with a turbo dryer with an average electricity consumption of about 0.5 kW, marked with “++”.
- The TEKA DW8 41FI dishwasher from Germany is especially popular, energy consumption within 0.5 kW corresponds to the A ++ classification. The presented model not only consumes energy in small quantities, but also significantly saves water and detergents.
Total. When purchasing a dishwasher model from various manufacturers, buyers should take into account its characteristics and energy consumption class, as well as be guided by the advice of experienced owners.
