How to calculate the water consumption in the dishwasher? Water consumption when washing dishes - Setafi

The water consumption in the dishwasher is primarily related to its capacity. The more sets of dishes the device can process in 1 cycle, the greater the volume of liquid spent. On average, this value is 8-11 liters. About what factors affect consumption, and how you can reduce it, is described in detail in this material.

Average water consumption

Consumption is defined as the volume of water (in liters) that the machine uses during one cycle to clean all loaded sets of water. How much water a dishwasher spends, on average, it is 9-11 liters, although it can also be 7-9 liters, as well as 12-13 liters. According to this indicator, all units can be divided into 3 types:

1. Compact - the narrowest (width 45 cm) consume 7-10 liters. at the same time, they can process from 6 to 8 sets of dishes in one cycle.
2. Full-size (width 65 cm) spend more water - from 9 to 14 liters. However, they can process 10-14 sets.

3. If we talk about how much water a professional dishwasher consumes, the volume will be 15-25 liters. Such units are used only in restaurants and other catering establishments.

Assessing how much water a dishwasher consumes, one should not forget about such a class of appliances as desktop devices. They are installed in apartments with small kitchens and spend only 6.5-7 liters of water.

What does consumption depend on?

How much water a dishwasher consumes depends on various factors. These are capacity, energy class, mode of use and even type of water. The main parameters are described in the following sections.

capacity

One of the main ones is the dimensions and capacity of the unit. It is clear that the larger it is in depth and width, the more dishes can be placed, for example, 10-12 sets. But even more will have to spend liquid.

Energy class

When evaluating how much water a dishwasher consumes, its energy class should also be taken into account. The indicator is indicated by letters, where the most economical option is A, and the least is G:

• A;
• IN;
• WITH;
• D;
• E;
• F;
• G.

Modern well-known manufacturers, for example, Bosch, Siemens, Electrolux, produce only economical class models from A to C. Lower categories of dishwashers with large water consumption are practically not found today.

Selected mode

Another important indicator that affects how much water a dishwasher consumes per cycle is related to the selected mode. For example, many models have a half load option. Then it is easy to understand what kind of water consumption the dishwasher has - it decreases by about 2 times (for some devices by 30%).

At the same time, quite a lot of modern devices have the option of "intelligent evaluation" of the download. In this case, the machine itself determines how much water is needed for a specific amount of dishes using the installed indicators. Thanks to this, the water consumption of the dishwasher per cycle becomes minimal. Various devices are equipped with a similar option, including compact ones that can be easily built under the countertop, like a washing machine.

There is another parameter that determines how many liters the dishwasher consumes. This is the washing mode that the user selects:

1. Economy - average consumption, about 8-9 liters. Suitable for daily processing at a temperature of 50 degrees.
2. Auto - complex mode with prewash, rinse and dry. Here it is definitely impossible to say how many liters of water the dishwasher consumes, since the range is quite wide - from 6 to 12 liters.
3. Low pollution - a fairly simple mode, the costs are 7 liters. In this case, how much water the dishwasher takes is quite comparable to the consumption during a normal hand wash.
4. Finally, there is also an intensive wash - in this mode, the consumption of the dishwasher is 10-12 liters.

Manufacturer

How much water a dishwasher uses depends in part on the manufacturer. If you make an overview of the most popular brands, you get the following picture:

1. Bosch devices have a wide range of functions and at the same time efficiently save resources. The consumption of water and electricity by the dishwasher is small - 10 liters and 0.91 kWh, respectively.
2. The water consumption of a Siemens dishwasher is noticeably less and amounts to approximately 7-8 liters.
3. As a rule, 8-10 liters are enough for Ariston Hotpoint devices. Moreover, such an average water consumption of the dishwasher allows you to implement all the functions, including pre-washing and rinsing.
4. Veko models are among the most affordable, but the consumption of the dishwasher per cycle is quite large and amounts to 10-12 liters.
5. The water consumption of the Indesit automatic dishwasher is also quite economical and is only 7-8 liters.
6. If we talk about how many liters a Candy dishwasher uses, the specific value can vary greatly between 8-13 liters.
7. Electrolux models spend 9-10 liters, which is quite economical. And it is not so important how many liters of water the dishwasher consumes, as its functionality. These devices operate in different modes and effectively clean even persistent fatty contaminants.

Thus, the consumption of water when washing dishes depends on a variety of factors and can take on different values ​​from a minimum of 6 to a maximum of 12-13 liters. It should be understood that savings are achieved due to the fact that the same water is used several times during one cycle. To do this, it passes through a filter that needs to be cleaned periodically.

The effective water consumption of a Bosch dishwasher and other models is also due to the fact that the liquid is sprayed under strong pressure. In addition, washing takes place at high temperatures, for example, 50-60 degrees, which cannot be done manually (there is a risk of getting burned).

Now it’s clear how many liters of water the dishwasher uses. Devices spend different amounts, but even if we take the maximum value of 12, this is not so much. Taking into account the current tariffs, one car wash costs 50-60 rubles. Even in the daily use mode, the costs per month will be in the range of 1500-1800 rubles.
