How many liters of water the dishwasher spends

Water consumption in a dishwasher

Dishwashers are far from novelty among household appliances. But they are far from every apartment. The acquisition of such a “home assistant” raises a natural question, how appropriate and profitable the purchase will be. Time saving is an attractive factor, but how much water the dishwasher spends?

Water consumption of a dishwasher. The indicator is not fixed. Consumption directly depends on the modification, additional functions and the water consumption class. The whole variety of existing models can be divided into three categories.

  • Compact desktop vehicles with low loading. Such models spend from 7 to 10 liters per cycle.
  • Medium household: built.In narrow or full.Size, separately standing. Narrow models have a smaller load volume, from 6 to 8 sets, full.Size contains up to 14 sets of dishes. Such a technique will spend from 10 to 14 liters for one sink cycle.
  • Large units designed for high loading, which are used in restaurants, cafes and canteens. Depending on the volume of loading, such dishwashers are consumed from 20 to 25 liters.

Due to which the savings are achieved

The dishwasher consumes water more economically thanks to the following features of the equipment:

Water in PMM is used at three stages:

After the first operation, the machine does not drain the water into the sewer, but passes it through the filtration system and uses it again. After washing dirty dishes, the equipment drains the liquid partially, and adds a fresh portion from the water supply to the residues.

I work in the field of repair of household appliances. Extensive experience in restoring washing and dishwashers.

Due to the high rate of water flow from sprayers, the quality of the dishwashing is increased and the process is accelerated, and the consumption of the resource is reduced.

Loading mode

Most modern models have a half loading function, which allows you to not only wash twice less dishes, but also spend half less fluid and electricity. Of course, in the car without such a function, you can wash the incomplete volume of dishes. Here are just the same water and electricity as much as with the full load of the tank.

The incomplete loading function is present in all the advanced models of Bosch, Ariston, Whirlpool and other manufacturers. In addition, in some expensive dishwashers, special water flow sensors are built.In, which control the volume of the incoming fluid, depending on the amount of dishes and the degree of its pollution.

Time saving. We make the calculation of costs

For one working cycle. Including sinks and drying, dishwasher is able to wash 9 sets of dirty dishes. Either 4 sets and kitchen utensils, which was used for cooking. It takes 2 hours. With a wash handle, so many dishes are spent from 30 minutes to 1 hour.

When the equipment works, they spend free time on other things. They spend only a few minutes to clean the dishes from food residues, load it into the car, and then put clean on the shelves.

Thus, we make an average calculation. If you calculate that the dishes are washed with their hands once a day, spending 60 minutes on it, then 21900 minutes come out (60 minutes x 365 days). This is 365 hours (21900 minutes: 60 minutes), or about 15 days (365 hours: 24 hours).

Does the dishwasher save water

If you have counters in your apartment, you can compare how much water is consuming for the cycle, and how much it goes with manual washing of the devices. At the same time, follow the cold water counter, because most PMM connects to a cold cranes (read the article about connecting the dishwasher).

Hot water contains a large amount of impurities. You will have to install an additional filter, as well as constantly mix it with a cold stream to achieve an optimum temperature.

To independently compare how much it is spent with manual washing and during the use of equipment, consider: how many sets are placed in your PMM.

Take, for example, 14 sets are 34 devices. According to the manufacturer, for one cycle, a narrow PMM uses 10 liters. While 43 liters were spent for washing the dining room with his hands in such an amount (the total consumption of hot and cold crane was taken into account; during the soap of the plates, the tares were blocked). Savings. There.

Why this happens? The secret of savings in the principle of PMM work. Many Bosch brand models, for example, are equipped with a water flow sensor. It is passed through the filter and can be used several times. In addition, nozzles let jets under large pressure, which allows you to effectively launder devices, and spend a little. Thanks to electronic control, the sensor will not allow you to use more than necessary.

There is savings or not? In one year of use of equipment, 8280 liters of water are consumed, which is profitable, even given the economical consumption of resources with manual sinks. If you spend more than 100 per day, then the savings will be even more.

Advantages of using a dishwasher

During the operation of the equipment, only cold water is spent, the tariffs for which are much lower. Each device is equipped with a heating heating element.

Users will notice that it also requires electricity and detergents for washing. All this is used for manual care, and there is much more free time.

You learned how many liters a dishwasher takes and whether it allows it to save. When choosing, pay attention to the class class, calculations should be carried out individually. But take into account an indisputable fact. This is a significant saving of time.

Additional ways to save resources

Additional programs that are provided by PMM manufacturers help save water. Among them, for example, washing kitchen utensils with weak contamination. This mode of operation will spend only 7 liters of fluid at full load.

Not all models of dishwashers have an economical mode of operation

There is also an economical mode that allows to wash bowls, plates and cutlery at a temperature of 50 ℃. Fluid consumption with it. From 8 to 9 liters. Modern premium PMMs are able to independently determine the degree of loading of the working chamber and the level of dishes of dishes. Accordingly, the obtained indicators automatically set the temperature and the rate of water flow.

What depends on the water consumption?

The efficiency of technology is largely determined by those who are the manufacturer, and what is the scientific and technical capabilities. Because they often provide the opportunity to develop modifications progressive and high.Tech.

Depending on what the level of water consumption is distinguished, such dishwashers are distinguished:

It is also customary to divide the PMM into classes in terms of economy. From A to G. Popular brands include Bosch, Candy, Electrolyux and others. After all, they produce only highly economic models of classes a-s. Non.Economic versions in European countries are no longer producing. And they were forbidden to import.

How much water consumes the apparatus for the cycle? This indicator is not regulated by some standards. The water consumption class has an impact:

All modifications were conditionally divided into three groups:

IMPORTANT! Consumption of professional dishwashers, which are installed at catering points-20-25 liters.

The dependence of water management on the modes and parameters “dishwasher

According to the degree of economy, “dishwashers” are divided, according to the standard adopted in Europe, in grades 7. The classes of the letter (from A to G) or the letter-symbolic marking (from A to D) are indicated, where proximity to the beginning of the alphabet and a larger number of advantages means a higher class with low consumption.

The type of water in the dishwasher is also affected by its type. Cars are:

  • Full-sized with loading 12-14 sets. And drainage 12-14 liters.
  • Narrow at 9-10 compls. And consumption of 9-10 l.
  • Compact at 6-8 sets. With a flow rate of 7-9 l.

But the “half load” function with a decrease in water back by 20-30% or the “intellectual assessment” of the apparatus is reduced to these ratios. In this case, the dishwasher itself determines what water consumption per cycle will be as effective as possible without prejudice to quality. Such opportunities are most often found in full-sized and narrow models or in compact premium units. The full functionality and choice of modes is determined by the manufacturer, but among the popular ones can be called:

  • Auto-mode. Wash dishes of any kind, including pans and pots, with preliminary sink rinsing and drying. Consumption for the 3rd class-6-11 liters.
  • Economy-mode. Copes with ordinary contamination at a temperature of about 50 ° C and consumption of 8-9 liters.
  • Strong pollution (intensive mode). With it, water supply increases (up to 10-11 l) and temperature (up to 70 ° C).
  • Fresh pollution. It is complete without preliminary washing, and the main one takes place at a temperature of 55-60 ° C with an economical consumption of 7 liters.
  • Duo Wash. A specific regime in the devices of some manufacturers, in which you can simultaneously wash and strongly contaminated dishes and the one that requires the use of a delicate mode.
  • Optosensor. Function with the choice of water stiffness.

Is the dishwasher economical

To understand whether the equipment is economical, we will analyze how much time it saves, how much water and electricity consumes.

Time saving. We make the calculation of costs

For one working cycle. Including sinks and drying, dishwasher is able to wash 9 sets of dirty dishes. Either 4 sets and kitchen utensils, which was used for cooking. It takes 2 hours. With a wash handle, so many dishes are spent from 30 minutes to 1 hour.

When the equipment works, they spend free time on other things. They spend only a few minutes to clean the dishes from food residues, load it into the car, and then put clean on the shelves.

Thus, we make an average calculation. If you calculate that the dishes are washed with their hands once a day, spending 60 minutes on it, then 21900 minutes come out (60 minutes x 365 days). This is 365 hours (21900 minutes: 60 minutes), or about 15 days (365 hours: 24 hours).

It turns out about 2 weeks of saved time, a tangible argument in favor of buying household appliances.

How much water does a dishwasher spend: how can it reduce its consumption

To wash the dishes with your hands, the amount of which corresponds to one loading of the dishwasher, on average about 70 liters of hot water and 30 liters of cold will be required. At the same time, even the most obsolete equipment models use no more than 20 liters.

Savings occurs due to the fact that the dishwasher uses the chosen water several times. The liquid does not go into the drain, as with manual washing, but is cleaned through the filtering device, and is used in the following production cycles.

So how much water does a dishwasher consume? Different models use different amounts of liquids. Water consumption is indicated in the instructions for the technique. This indicator is not regulated by standards. It depends on the constructive solutions used in a specific modification, and the availability of additional functions.

Modifications are conditionally divided into three groups:

  • Household appliances are full.Size and narrow. Spends from 9 to 14 liters;
  • Compact. Spends from 6.5 to 9 liters;
  • Large devices. Professional equipment that is installed at catering points, consumes from 20 to 25 liters.

Ordinary dishwashers, depending on the dimensions, are divided into full.Sized and narrow. This criterion shows how many dishes the equipment contains in one cycle. So, the full-sized wash will wash 10-14 sets of dishes with a maximum water consumption up to 14 liters. The narrow process will process 6-9 sets, using no more than 10 liters of fluid during the process.

Compact units for one cycle are laundered from 6 to 8 sets, while the maximum water consumption is 9 liters. They are suitable for a small family so that you do not have to save the dishes until the more overall load is loaded.

Reference. European brands, such as Bosch, Siemens, Electrolux, are considered leaders in water saving. They pay special attention and saving electricity.

A dishwasher that consumes not more than 7 liters of water, but has a large capacity is also presented on the market. It belongs to premium products and is highly worth. For example, the full.Size Siemens SN 236100 ME consumes 6.5 liters of water, while launders up to 13 sets of dishes. Economic equipment has less water consumption than ordinary models, 40%.

The fluid consumption is affected by the presence of additional modes in the aggregate. Reducing costs by 20-30% occurs due to “half loading”. Saves consumption function “Intellectual assessment”, in which the technique itself solves the amount of the required liquid for the cycle. Most often, these modes are equipped with premium machines of all types: full-size, narrow and compact.

Manufacturers themselves determine the set of additional modes and functions for each model. The following functions affect the flow of water in the dishwasher:

  • Economy-washing dishes at a temperature of 50 ℃, water consumption-8-9 liters;
  • Author-involves preliminary washing, rinsing and drying, consumption-6-11 liters;
  • Weak pollution. Consumption of about 7 liters;
  • Intensive washing-mode increases water consumption to 10-11 liters.

To reduce the flow of water, you should choose an economical machine of famous European brands. Take into account spaciousness based on your family needs. Select additional functions, such as “economy” and “half loading”, which reduce water consumption.

Electricity costs when washing dishes

When washing dishes with hands, electricity costs are small. They are only in the coverage of the workplace. And if an energy.Saving light is installed, they are minimal. Electricity costs will increase if an electric boiler is used to heat water.

Dosseal equipment during operation consumes electricity constantly. According to European standards, there are 7 classes of energy consumption, which are indicated by Latin letters from A to G. The most economical dishwashers belonging to class A, B, C. It is indicated in the operating instructions and on the sticker, which is placed on the outer surface of the device.

Whether the device saves resources?

There is a meaning in savings if the counters are installed on the supply of H2O. Economicity will be considered by the example of the Siemens SN 66M094 model, designed for 14 sets of dishes.

These are 63 items, including plates, cups, pots, cutting board and cutlery. It will wash them for 3 hours (intensive mode), and it will take only 10 liters of water.

If you wash at least half of these 63 items, but manually, you need, on average, 20 minutes and 43 liters of water (hot and cold). In terms of liquid resources, the savings are obvious.

10 Things To Consider Before Buying An Integrated Dishwasher

To evaluate real savings, you should take into account the costs of light, detergents “pills”. It turns out that the electricity “leaves”, but the water is saved. In general, the costs of manual and machine sinks are approximately the same.

Water consumption

The water consumption of the dishwasher varies depending on the brand and year of release. The general rule is observed: the more expensive the dishwasher, the less it consumes. No matter how simple and old the car is, its consumption rarely exceeds 20 liters. Modern devices are not even in economical mode consumes no more than 10 liters.

Consumption depends on the program, power of the dishwasher and the degree of pollution of the dishes. In order to prevent overspending, it is enough to soak dishes with dried.Up or burned food residues. After that, she easily copes with them even on an economical mode.

Suppose you need to wash 10 sets of dishes. Theoretically, you can calculate that about 2 liters flows from the tap for a minute. Water. Even the most skilled hostesses will take at least 10 minutes for so many dishes, and this is at least 20 liters, which significantly exceeds the consumption of the machine.
