How to find out how much water an automatic washing machine consumes?

The water consumption of a washing machine is one of the technical indicators that affects the efficiency of washing and the efficiency of equipment. According to experts, the device wastes up to 25% of the total volume of cold water consumed by a family of 3 people. The level of water consumption depends on the degree of loading of the drum, the technical condition of the machine and the selected washing and rinsing modes.

What affects consumption?

What determines the water consumption of a washing machine:

• brand and manufacturing company;
• washing program, type of fabric and heating;
• loading the tank;
• use of additional functionality;
• tank size.

The following programs demonstrate minimal consumption of water resources:

The operation of some programs and functions leads to increased water consumption and increased amounts in utility bills.

Energy consumption classes (energy efficiency)

The energy efficiency class determines the amount of energy that the device uses. The higher it is, the more effective the costs are. This parameter is considered one of the main indicators of the quality of the device. On average, the power of a washing machine can reach 4 kW. Today, many are trying to save resources, so they tend to use household appliances that belong to class A or B.

The presence of the letters F or G characterizes the quality of energy saving as poor and very poor, D and E – normal and satisfactory. Before assigning an energy saving class for parameters such as washing, spinning, and energy efficiency, a comparison is made with the standard. They have a special installation with constant performance indicators. The technique under study is compared with it.

Energy efficiency class table

Nowadays it’s difficult to find a washing machine with a class below B on sale.

Another energy consumption criterion is programmable mode optimization. The less time the machine takes to wash, the less electricity is consumed. For example, a device with energy efficiency C washes very dirty clothes in 2 hours 40 minutes, and a more economical unit of class A washes them in 2 hours.

Just 10 years ago, manufacturers produced equipment only with efficiency A; today, thanks to the latest technologies, there are devices of class A+, A++ and A+++. They consume less electricity by 10, 30 and 50%, respectively. The service life of budget models is at least 5 years, more energy efficient - from 15 to 20 years. During this time, it is possible to save a large amount of electricity.

Consumption depending on model

Companies that produce washing machines independently determine how much water the tank should be filled with.

Some top-loading washing machine models from various brands can consume several times more resources than side-loading appliances.

How much H2O is lost in one wash?

Water consumption directly depends on the capacity of the device.

Regular (narrow, full-size)

These are middle-class machines, where a narrow one can wash 9 sets of dishes in 1 cycle, and a full-size one can wash 10-14.

The average consumption for such equipment ranges from 9 to 14 liters. In this case, we are talking about cold water, since PMMs are often connected to cold water supply in order to save resources. That is, to wash 9 sets of dishes, the machine needs only 9 liters of water - this is quite economical.

The peculiarity is how this technique works. The PMM collects water once and uses it to wash dishes. In this case, the water passes through the cleaning filter during the cycle. Towards the end of the procedure, the technician again takes water to rinse the dishes and completes the cycle with a final rinse.

The cost-effectiveness of popular PMMs priced up to 40,000 rubles is presented in the table:

Economical

Dishwashers are produced that spend only 7 liters per cycle. Usually these are premium segment models or compact PMMs. Low water consumption does not always mean low capacity of equipment.

There are models with a large load but minimal consumption, but they are expensive. Example - Siemens SN 236100 ME, whose water consumption is 6.5 liters.

This is a full-size appliance, designed for 13 sets of dishes, with an energy consumption class of A++. As a rule, economical models require 40% less water than conventional ones.

Compact PMMs with a small capacity, designed for 6 to 8 sets of dishes, are also called economical. They consume the same amount of water as the narrow versions - 6.5 - 9 liters. It turns out that their level of water consumption is similar to large dishwashers, but they are capable of washing much less dishes.

Comparison with hand washing

When washing by hand, in order to wash the amount of dishes that would fit in the PMM, you will need 70 - 100 liters of water, both hot and cold.
That is, a machine with a flow rate of 7 - 14 liters requires 10 times less water.

Approximate calculation:

• Dishwasher. 14 l x 360 (days) = 5040 l (cold water);
• hand wash. 70 l x 360 = 25200 l (12000 – cold, 13200 – hot).

The price of 1 cubic meter of water depends on the region of residence. For example, a cold one costs 30 rubles, a hot one – 100.

It turns out:

• PMM. 5040 x 30 = 151.2 rubles;
• manual. 12 x 30 + 13.2 x 100 = 1680 rubles.

If you take into account water consumption, then a dishwasher is much more economical than washing by hand

Maximum and minimum flow

The technical data sheet of any washing machine contains test results .
They are carried out in laboratory conditions, with various loads on household appliances.

Testing allows you to set minimum and maximum water flow rates. The smallest volume is 38 liters, the largest is 80 liters.

Based on these data, it is possible to calculate the average amount of water resources consumed. It is equal to 59 liters. Many manufacturers cite these numbers in their documents.

You can check their . To do this you need:

1. Record the readings of the meter that is connected to the cold water pipe.
2. Turn on the machine on the longest mode.
3. Check the meter again by calculating the cold water consumption. The resulting figure is the maximum water consumption of the washing machine.
4. Wash the clothes again on the fastest cycle.
5. Note the counter indicator. This is the minimum cost.
6. Calculate the average value and compare it with the numbers given in the washing machine data sheet.

Standards

The average water consumption is indicated by the manufacturer in the washing machine data sheet. If you compare different products from different manufacturers, the indicator will be different, but some average figures can be derived. How much water does a washing machine use per wash?

According to data published by experts, the volume spent in 1 washing cycle ranges from 38 to 80 liters. Using simple calculations, you can calculate that the average water consumption per wash is 59 liters.

Important! If an automatic machine uses more water, it means either the equipment is faulty or you are choosing too water-intensive modes. In any case, you need to pay attention to this, as well as to.

How to save money?

To reduce resource consumption and your own financial costs for utility bills, you can take advantage of the following savings opportunities :

• completely fill the tank with laundry;
• do not use the pre-soak option if there are no difficult-to-remove stains on the clothes;
• use high-quality laundry detergents to prevent repeated treatments;
• use only powders intended for washing machines; they create a small amount of foam and rinse out faster;
• give preference to the quick wash mode.

Which devices consume the most electricity - comparison

There are many factors that influence the average electricity consumption of a single-family home or apartment, and the percentage contribution of individual devices to energy bills is as follows:

• 30% of energy is consumed by the refrigerator,
• 21% of energy is consumed by lighting.
• 20% of electricity is consumed by an electric stove,
• 10% of the energy is consumed by the washing machine,
• 6% of energy is consumed by the TV,
• 5% of energy is consumed by an electric kettle,
• 3% of energy is consumed by the computer,
• The rest of the electricity bill is generated by other electronic devices such as the radio, dishwasher and so on.

Advantages and disadvantages of quick wash

It would seem that the “Quick Wash” function can always be used, because it is convenient and economical. But that's not true.

The fact is that the program takes place at low temperatures. In such conditions, you can wash lightly soiled items that you change every day: T-shirts, socks, shirts, blouses. At the same time, there should be no complex or old stains on the fabric. A quick cycle only allows you to freshen your laundry and rid it of unpleasant odors.

• It is not effective to wash heavily soiled and worn items in this mode.
• Also, towels and bed linen are not washed properly.
• This is an intensive program and is therefore not suitable for thin, delicate fabrics or items that require hand washing.
• The maximum effect can be obtained with half the drum load. You also need to use less detergent. At low temperatures, powder granules do not dissolve well, so the laundry will not be rinsed when fully loaded.

At what degrees does the fast mode work? The water temperature is 30-40 degrees. You cannot always use the program, since to remove dust mites and stubborn dirt you need to run a full wash cycle at 60 degrees.

If you smell a musty smell from your laundry or drum, it's time to run a hot water cycle. Constantly running the washing machine in cold water leads to the formation of mold and mildew on the hatch cuff, which then ends up on your clothes.

How long does a quick wash last?

How many minutes does Quick Wash last? Depending on the washing machine model, the cycle duration ranges from 30 to 40 minutes. There is a “Super Quick Wash” program that will take 15 minutes.

Despite the short cycle time, the machine carries out the cycle completely: washing, rinsing, spinning.

How to use the mode correctly

Sort your laundry before loading. Separate items from each other by type of fabric, separate white clothes from colored ones. Set aside heavily soiled and stained laundry for a full wash cycle.

How many times does the machine fill with water?

During normal operation, the machine draws and drains water several times during a cycle - at least twice: once for washing and once for rinsing. The exact amount depends on the selected program and its duration.

What to do if quick wash doesn't work

If this program does not work in your machine or there is no mode with this name at all, pay attention to other cycles. For different manufacturers, this mode may be called “Quick Wash”, “Accelerated”, “Express Mode”, “Quick 30” and so on. All programs that last less than 40 minutes are suitable for you.

If you don’t know how to install and enable a quick program, special icons on the control panel will tell you about it. Turn the toggle switch so that it points to the mode designation and start the program.

This also applies to top-loading machines.

It happens that the mode does not start at all, the light blinks. Then check whether the hatch door is tightly closed. If everything is fine, reboot the washer by doing this:

• Unplug the machine.
• Wait 15-20 minutes.
• Turn the washer back on. If the program starts normally, it means there is an error in the system.

Siemens WS 10G240 OE

Another “masterpiece” of German mechanical engineering is the Siemens WS series washing machine. A relatively inexpensive and economical model, consuming an average of 40 liters of water per wash cycle. By washing clothes using the “quick wash” program, you can further reduce water consumption to 37 liters.

Under normal conditions, unless there is a malfunction, any of the above machines, even with record low water consumption, washes clothes perfectly and the fact of saving water does not in any way affect the quality of the wash. It’s another matter if the user, in pursuit of savings, chooses unjustified washing modes for a certain type of laundry or loads more laundry into the drum than the maximum drum load indicators allow.

When preparing to wash your items, read the instructions that came with your washing machine. Act in strict accordance with the recommendations of the instructions, and then the quality of washing and water consumption of the washing machine will satisfy you. In order to solve the problem of excessive water consumption by a washing machine, you first need to identify it.

In other words, you need to find out whether your machine really spends too much water or if it just seems so to you. What should be done?

1. Take a look at the passport of your washing machine and see how much water your machine should draw and consume in 1 wash cycle.
2. Select the most economical washing program that your machine has in its “arsenal” (usually “quick wash”, “accelerated wash”, “quick 30”, etc.) and record the volume of water consumed using the water meter.
3. Select the most water-intensive washing program (usually programs associated with washing cotton or bulky items) and also track how much water was used using the water meter.
4. Based on the resulting indicators, calculate how much water your washing machine uses on average.

Note! When you measure the water consumption of the washing machine, do not forget to turn off all the taps in the house, as well as the toilet tank, for the duration of the wash, otherwise the calculations will be incorrect. If, as a result of the measurements and calculations, you received a value close to what the manufacturer indicates in the passport (+- 15 liters), this is normal

This means that everything is fine with your washing machine and there is no need to take any measures. But if the actual water consumption is much higher, say 30 or even 50 liters more than the value declared by the manufacturer, urgent measures need to be taken. If you do not violate the instructions for using the washing machine, most likely there is a malfunction and you need to contact a specialist

For our part, we advise you not to climb into the car body yourself. Troubleshooting on your own may well be fatal for your washing machine. It is better not to skimp on a specialist, but later save on water when the machine malfunction is professionally repaired. If you decide to find and correct the defect yourself, read about how to properly disassemble a washing machine.

To summarize, we note that everyone who uses an automatic washing machine needs to know how much water it consumes. This is necessary not only to save on utility bills. Increased water consumption is an indirect sign of a serious malfunction that can lead to the failure of the home assistant.

When the owners of their household appliances find out how much water an automatic washing machine consumes in one wash, an emergency economic council is convened in the house. The agenda is how to avoid excess fluid consumption.
