What to look for when buying a dishwasher?

What to look for when buying a dishwasherThe desire to buy a dishwasher often results in unsuccessful attempts to find the best “home helper” among dozens of brands and dimensions. Such a device is not cheap, and buying a dishwasher at random, relying on the help of a consultant or focusing only on the price tag is short-sighted and very risky. It’s better to understand the issue in advance and when choosing, pay attention to the presence of a particular model with suitable characteristics and capacities. What parameters are in question, we will describe in detail below.

Types of cars and their loading

First of all, we evaluate the appearance of the machine that has attracted us, more precisely, its capacity and dimensions. These characteristics are interrelated and determine the maximum load of the working chamber for one cycle. This is expressed in the number of sets of utensils - a standard set for one person, which includes plates for soup, salad and side dishes, as well as a spoon, fork, knife and mug. Pots, pans, baking trays, and other optional utensils are counted separately.

Information about the capacity of the model is displayed on the price tag by the number of sets. Also, the type of dishwasher indicates the permissible load volume.the loading volume of the dishwasher is important

  1. Full-size, depending on the brand, can accommodate from 10 to 18 sets, which is suitable for families of 3-6 people. They differ in width of 60 cm, numerous modes and multifunctional equipment. All this affects the price - they cost more.
  2. Compact options are designed for fewer dishes and are ready to “accept” no more than 8 sets. They are also inferior in technical terms, as they have a modest set of options and programs. But their advantage lies in the small size, which allows you to install the machine on the countertop or in the cabinet. Their cost is lower, but they are suitable only for a summer residence, single people or a family of 2 people.
  3. Narrow machines are the “golden mean,” which, along with a compact width of 45 cm, boasts an excellent load of 6-13 sets. They are considered the most popular and ideal for average families of 4-5 people.

Atypical sizes are found, so we carefully study the marking.

Next, pay attention to the type of installation. All dishwashers are divided into separate and built-in. The former are freely placed anywhere and purchased if the kitchen is already furnished and it is impossible to integrate them. The latter are arranged under the cabinets and are “hidden” directly in the cabinets. The machine can be fully or partially integrated. In the first case, the facade door will hide the entire unit from the eyes, and in the second, the dashboard will protrude.


It is important, before buying a dishwasher, to evaluate its efficiency. It is logical that during operation, the dishwasher will actively consume water and electricity. How much utility bills will grow can be understood by carefully studying the factory markings.

First of all, we look at energy consumption. As a rule, each unit has a special sticker where the assigned class is given - from A +++ to D. The most profitable are models A, the consumption of which does not exceed the mark of 0.8-1.5 kW per hour for one standard cycle, and more energy-intensive - all letters below B. It costs from 1.06 kW per hour, since these machines are either too outdated and devoid of modern cheaper technologies, or designed for production capacity and are not suitable for domestic efficiency dishwashers

Do not forget about the flow of water. Most often, all modern models do not take more than 15-17 liters from the water supply system, which is more economical than 60 spent liters for a manual wash. But it is worthwhile to understand that with intensive mode or a plentiful rinse, the figure given will grow a little.

Modes of modern models

Available functionality is no less indicative. The basic set includes pre-soaking, washing itself, rinsing and blowing with hot steam to dry. Often, the list is supplemented by a couple of modes for certain types of dishes, glass, plates or pans. But more often manufacturers offer other options:

  • express washing (reduced rinsing program for minor contamination);
  • intensive washing (prolonged soaking and enhanced cleansing);
  • delicate mode (for fragile materials such as porcelain and crystal);

The dishwasher also simplifies the operation of the built-in crusher for waste left on the plates, child locks, delayed start within 24 hours, additional filtering and self-diagnosis of system malfunctions. Many manufacturers offer a working camera backlight, sound, and automatic mode selection by scanning loaded dishes. However, all modifications directly affect the price tag and subsequent repair of the machine, so it is better not to overpay for the "extra" functions.

How noisy is the machine?

If the kitchen is remote from the bedrooms and a fully built-in model is purchased, then you can not worry about the noise level. But for owners of small families, studios and freestanding cars there is a little advice - pay attention to noise reproduction.

For different dishwashers, this parameter can vary from 37 to 65 dB, and the smaller the number on the label, the more quietly the machine will work.

Completely silent machines are expensive, so it’s more reasonable and economical to stop at units with 45-50 dB. Do not forget about the damping of the sound - the kitchen facade will mask not only the dishwasher itself, but also the vibrations emanating from it.noise level of different dishwashers

What tools are used?

Conventional dishwashing gels are strictly prohibited in dishwashers. For automatic washing, special detergents are provided, which can be purchased at almost any hardware store. There are domestic, and foreign, and expensive, and cheap brands, but the defining characteristic will be the environmental friendliness of the composition.

The agents are softer, have a natural base and are hypoallergenic, while the usual ones, on the contrary, consist of harmful chemicals, irritate the respiratory tract and mucous membrane (if ingested), and often cause allergic reactions. But aggressive substances deal with pollution better and faster, since it is impossible to wash dirty dishes from the first time with environmentally friendly powders. The cost of boxes and bags with the inscription "Eco" is several times higher, so we focus on our financial capabilities.dishwashing detergents

Detergent alone is sometimes not enough. To ensure the dishwasher has a long service life, it is necessary to use emollient salt and prevent scale formation. You will also need a rinse aid, with the help of which the dishes are better cleaned of cleaning components and acquire a shine. Flavors are optional but desirable, giving the plates and cups a pleasant smell of freshness or herbs. Dishwasher cleaning products vary in form.

  1. Gels. They are economical, easily dosed, rinsed out quickly and, most importantly, do not have abrasive components in their composition, which allows you to gently wash dishes without scratching. Great for daily use. About 30 ml are needed per wash.
  2. Powders. The most popular tool, characterized by availability and low price. But there are many drawbacks: it is necessary to soften the water additionally, the granules wake up past the tray and scratch the plates. About 25 g are needed per cycle
  3. Pills. Their main advantages are versatility and dosing. Rinse aid and softening salt also come with the powder. The disadvantage is the high cost. One tablet is designed for one cycle.

Typically, the manufacturer in the instructions indicates the preferred type of agent used and the required dosage. Sometimes specific models have some limitations on the use of certain tools.

We achieve the best quality of work

The washing class is another parameter that shows in advance how well the dishwasher washes dirt. Almost all modern models have the highest level A, so it is extremely difficult to make a mistake with the choice. However, do not forget that the degree of purification is affected not only by production capacity, but also by other factors:

  • Features of the design of the working chamber. We look at the shape, number and location of sprayers and nozzles, as well as the ability to adjust the inclination of the grilles.
  • Hardness of tap water. If the water entering the house is too saturated with impurities, then wait for scale and stains on the dishes. Soft water is not better, as it does poorly with pollution. To avoid trouble, you should take care of its sufficient softening / tightening or pay attention to the dishwasher's ability to automatically adjust the level of hardness.
  • Detergent quality. It is important to use trusted manufacturers, correctly select the appropriate formulations and correctly calculate the required dosage.

Last advice - do not forget about the rules for loading dishes on the wire rack. If you place the plates in specially provided holders and at a sufficient distance from each other, then the chances of a high-quality result are many times greater. We are also mindful of the choice of regime - there is no point in heavily soiled dishes stopping at an express sink.

We look how it dries

The dishwasher should not only wash, but also dry. Then the hostess will not have to wet her hands and waste time wiping the plates. Therefore, we look at the type of drying installed in the machine:

  • Turbo dryer. It is a fan that evenly blows dishes with hot air. All this will require a lot of electricity.
  • Condensation drying. It works like this: plates are poured with boiling water or steam, after which they dry on their own in free mode. Drying takes longer, but the cost of such dishwashers is lower.
  • Intensive drying. A modern alternative that allows you to quickly and inexpensively get dry dishes due to the air circulation created in the chamber.

Intensive drying is only gaining popularity, which is why dishwashers equipped with it are not cheap. The main thing is to focus on your needs: if there is no need to dry quickly, you can take an inexpensive condensation.

Equipment Security Level

Technical capacities are not everything. You must also think about your safety. Therefore, we pay attention to the following points:

  • Leakage protection. It’s great if the dishwasher has full protection with the Aquastop system.
  • Child lock The ability to lock the control panel by holding certain keys does not hurt.
  • Automatic shutdown and draining of water when opening the door of the machine during washing.

You can purchase special door locks that prevent the child from reaching the dishwasher.

Knowing the useful functions, decoding of signs on the dishwasher and some tips, you can choose an excellent model without too much thought and doubt. And free up your time for more meaningful things.
