When purchasing a washing machine, people think about how many resources it will consume. As utility prices increase year after year, home appliance owners want them to be economical. There are models that can be washed in economical modes. You need to know not only their name, but also understand what the water consumption of an automatic washing machine will be. This indicator is calculated based on several criteria.
What does water consumption depend on?
After purchasing a washing machine, utility bills can increase several times. Several factors influence this. If they are not taken into account, owners of household appliances face significant waste every month.
Let's determine the main factors influencing water consumption:
- amount of loaded laundry;
- washing programs;
- machine malfunction.
Modern types of machines can wash clothes in economical modes. Each brand offers its own solutions. When the drum is fully loaded, the average consumption will be less. If a person washes a little, but does it often, the equipment consumes more resources. Consumption may increase if the washing machine is connected incorrectly or if it malfunctions. For example, if the inlet valve breaks down, liquid enters the tank when it is not needed, and the machine wastes a large amount of water daily.
Electricity consumption
The amount of electricity used is determined by the following indicators:
- unit power;
- selection of modes that ensure rational consumption of resources.
The efficiency characteristics of the equipment are indicated in the energy consumption class. It is recommended to choose class A products, perhaps with one or two pluses, or B.
The specified equipment consumes on average from 0.8 to 1 kWh during one operation. During one wash, the power ranges from 300 W to 2 kW, depending on the selected mode and unit parameters.
Approximate calculation of energy consumption for 2 weekly washes of 3 full cycles per week for a machine that spends 1 kWh per full cycle:
- 6 kWh will be consumed in a week;
- per month – up to 25 kWh;
- the cost of electricity used per month by an automatic machine, at a tariff of 3 rubles. is: 25*3=75 rub.

The calculated indicators may differ depending on the intensity of use of the equipment and the degree of soiling of the laundry, which affects the choice of mode.
Water consumption indicators for one cycle
How much water does a washing machine use on average? This figure is indicated in the passport document. The volume of water consumption per wash can be 38-80 liters. The average figure is approximately 60 liters. If you're spending a lot, think about whether you're choosing too much water and whether your appliances are working properly.
If you suspect that increased utility bills are related to the operation of the machine, open its passport and look at the average water consumption figures. Next, carry out simple calculations based on the indicators of water meters. Remember that the larger the unit, the more resources it needs. If you have an old model, it is not always correct to rely on the volume of consumption indicated in the passport. The older the equipment, the higher its wear and tear and resource consumption.
What affects water consumption?
Any washing machine, no matter how well-known the manufacturer it is made, uses a fairly large amount of water. The average consumption is usually indicated in the product data sheet, and this indicator varies greatly for different devices.
As a result of research in which more than a hundred washing units participated, experts concluded that the minimum amount of liquid spent on one wash is about 40 liters, and the maximum is twice as much. Thus, the average consumption per cycle is 60 liters. If this indicator is exceeded two or three times, it means that there is some kind of malfunction in the machine.
The following factors influence water consumption in an automatic machine:
- Model. Modern advanced technology, unlike old uneconomical units, has programs and special functions that can significantly save water resources.
- Program. The amount of liquid used also depends on the selected operating mode of the washing machine. When developing programs, the designer includes in the algorithm the washing duration, rinsing time, spin speed and the volume of liquid poured into the tank. When running long, water-intensive programs, more than average water will be wasted.
- Loading. With an optimal load, that is, when washing exactly the amount of laundry indicated in the product data sheet, the water consumption will be less than with a small load and frequent use of the machine.
- Additional rinse. The housewife is not satisfied with the quality of the wash; there are white stains from the powder on the products or stubborn stains have not been removed - and she activates the re-rinse function, which is available in many units. Naturally, in this case, much more water will be wasted than average.
- Malfunctions. The presence or absence of problems in the machine determines the amount of liquid used. If the device is not connected correctly, the pressure switch has failed or the pump is clogged, the machine can endlessly draw and discharge water into the sewer, and the laundry will remain dirty.

Water consumption for different models
Lg machines have 8 water flow levels.
For them it can be 7.5-43 liters. How much water does an Lg washing machine use? If we assume that we wash 5 kg of laundry, this figure will be from 48 to 56 liters per cycle. When calculating the average water consumption for “washing machines” of this type, you need to take into account different types of fabrics. The main “counting mode” is “Cotton”. When loading 5 kg of cotton items, the water consumption will be approximately 45 liters. To wash 2 kg of synthetic fabrics you need approximately 40 liters, and if the fabric is thinner, the machine takes 50 liters.
Lg models have “Steam Wash”. When this program is activated, water is sprayed onto items and mixed with washing powder. Using this mode allows you to use resources more economically.
The features of Indesit machines allow them to economically use and consume water when washing. 5 kg of things takes 43-52 liters. All models are equipped with the Eco Time option. This “smart” option uses resources sparingly.
Anyone who uses a full-size machine from Samsung will appreciate it for its efficiency and reliability. Compact models are not suitable for washing double bed linen sets. Large items are difficult to fit into the drum, but the amount of water will be decent - about 40 liters per cycle. It’s better to buy a full-size “washing machine” from this company, which will fit everything you need.
How many liters of water does a Bosch machine use for one wash? The standard figure does not differ from the figures typical for other companies. When loading 5 kg of things into the drum, the consumption will be from 40 to 50 liters.
Water consumption of the INDESIT automatic washing machine
Indesit washing units use water quite economically, but we must not forget that water consumption depends on the Indesit model. Washing 5 kg of laundry can take from 43 to 52 liters of water.
Washing machine Indesit
Indesit brand machines have an Eco Time function, which allows you to reduce washing time due to minimal use of water consumption.
Also, when washing in INDESIT, you can save water:
- maximum load of dirty laundry;
- refusal of the pre-wash function if the laundry is not heavily soiled;
- using special products, such as stain remover, to quickly wash clothes;
- avoiding washing powder for hand washing, as it creates a large amount of foam and will require a lot of water to properly rinse the laundry. This applies to all brands of washing machines.
Indesit has a My time model, which allows you to save water even with small loads of laundry by an average of 70%.
Indesit washing machines, regardless of the model, are very convenient in that all modes are numbered and divided into groups: cotton, synthetics, special modes. The menu will be clear even to a child.
Economy modes and programs
Savings largely depend on what temperature setting you choose for your washing machine. The choice of temperature for all models ranges from 30 to 95C and depends on how dirty the laundry is. The following factors also affect water consumption:
- types of fabric and their combinations;
- duration of one cycle;
- number of rinses.
There are several modes that can be called economical. They can be found in almost any washing machine:
- fast. Sometimes it is designated as “accelerated”. Time – from 15 to 40 minutes. Suitable for washing items that have not been heavily soiled and do not require pre-treatment;
- casual or daily. Designed for washing acrylic, polyester and polyamide fabrics. They are undemanding to care and wash quickly;
- economical (or economical) - the machine washes in the range of reduced consumption of water and electrical resources. At the same time, the cycle time is significantly longer.
The most economical brands
Experts identify the four most economical brands of washing machines:
- Hotpoint/Ariston AQS1D29. Italian made model. Its water consumption is 40 liters per 1 wash cycle. When the accelerated mode is activated, the consumption will be reduced to 34 l;
- Samsung WF60F1R2F2W. The average consumption of a Korean “washing machine” is 39 liters, with a drum volume of 6 kg. In super-fast wash mode, consumption can be reduced to 35 liters;
- Bosch WLG20265OE. A German machine, the average consumption of which is about 40 liters. When activating one of the programs, you can reduce water consumption to 36 liters;
- Siemens WS 10G240 OE. Resource consumption – 40 liters per cycle. If the unit is working well, you can use the fast mode, washing things efficiently.
Helpful advice! Thoughtless use of economical and fast modes can lead to damage to the laundry and the washing machine.
Water use
The amount of water used by the specified equipment during operation is determined by the following factors:
- model - the presence of programs that allow you to save resources;
- degree of loading - with the maximum amount of loaded laundry, the volume of consumption is reduced;
- technical condition - in the presence of certain malfunctions, consumption indicators may increase sharply;
- user demands - many housewives are not satisfied with the quality of washing or rinsing clothes, so sometimes the unit is restarted, which leads to an increase in the amount of resources used.
The average consumption parameters of modern automatic machines range from 0.04 to 0.08 cubic meters per full cycle.
With the intensity of equipment use according to the above calculation, with an average amount of water used per cycle within 0.06 cubic meters, consumption will be:
- per week – 0.06*6=0.36 m³;
- per month - 0.36 * 4 + 0.06 = 1.5 m³ (one wash is added, since there are 3 - 4 days more in a month than 4 weeks).
