Water consumption per cycle
The volume of water used by the washing machine during a standard wash cycle. It is measured while washing the maximum amount of cotton underwear for this model with a normal programme and a temperature of 60 degrees.
When evaluating efficiency, one should consider not only the actual water consumption but also the maximum load. So, for example, a model with a load of 7 kg and a consumption of 49 litres per kilogram of laundry will be more economical than a model of 5 kg with a consumption of 40 litres: the first consumes 49/7 = 7 litres per 1 kg of laundry, the second 40/5 = 8 litres per kilogram. This moment is important, first of all, if a large amount of washing is expected.
Many modern automatic washing machines are equipped with intelligent systems that can adjust the water consumption to the actual load and avoid overspending.
Dryer
Some washing machines can not only wash but also dry the washed clothes. Drying is carried out using a stream of warm air (temperature depends on the type of fabric) supplied to the drum. At the same time, the drum itself rotates, periodically changing direction and speed for more uniform drying.
Drying can be carried out both by a timer (a certain time) and by humidity (when the machine itself determines when to stop drying). Particularly advanced models allow you to adjust the residual moisture of the laundry from slightly damp (optimal for ironing) to completely dry.
The presence
of the laundry drying function is useful in cases where there is no place in the apartment for hanging laundry or when there is no time to wait until it dries. On the other hand, such machines consume electricity intensively (sometimes so much that it makes sense for them to have a separate power supply line) and are much more expensive than
non-drying models. In addition, due to intensive and uneven processing, the laundry is prone to overdrying and wears out faster than conventional drying.
Drying capacity
The maximum amount of laundry that can be loaded into the washer to dry.
For more information about this mode, see "Dryer". Here it is worth mentioning that the weight of dry laundry is indicated in the specifications, and the maximum load for this mode is usually 1.5 – 2 times lower than for washing — this is due to the peculiarities of the process. In other words, you should be prepared for the fact that after washing with a full or almost full capacity, you will have to dry the laundry in two stages. However, the need to completely dry so many things at a time arises relatively infrequently — in most cases, part of the laundry can be dried traditionally.
Number of programmes
When selecting a washing machine based on the number of programs, it's important to keep in mind that having 12 to 16 modes is typically sufficient. More programs, such as 25 or more, may simply offer variations of the same standard programs with different settings for duration, temperature, spin speed, etc. This may not necessarily provide a wider variety of programs. Additionally, machines with the same number of modes may have different specific sets of programs. While more modes increase the possibilities for selecting an optimal mode, it also significantly increases the cost.
Spin class
The quality of the machine spin mode. The spin class depends on the residual moisture content of the laundry after the end of the washing programme and is indicated by the Latin letter from
A to G, where A is the best efficiency,
B and C are good,
D, E are medium, F, G are very weak. The quality of the spin is closely related to the maximum number of revolves of the drum in this mode. Naturally, machines with better spin quality are more expensive, other things being equal.
Energy class
This parameter characterizes the efficiency of electricity consumption by the washing machine. Classes are designated in Latin letters from A to G, in ascending order of energy consumption. At the same time, in class
A there are subclasses "A+", "
A++ " and "A+++"; more pluses means less energy consumption, and the most economical option to date —
A +++ — outperforms class A by almost a third.
Machines of classes
A + and above are today considered economical, class A — medium, lower classes — high consumption. However, indicators below A are typical for semiautomatic low-cost models. As well as for units with dryers (see above) in which high energy consumption is simply inevitable.
Energy class (new)
This parameter characterizes the efficiency of electricity consumption by the washing machine. Classes are designated in Latin letters from A to G in ascending order of energy consumption. This was originally conceived until more energy-efficient models pulled up to class A, which eventually received the marking A+, A++, and A+++. Further development of technology has made it possible to go even further, and in order not to produce pluses in energy efficiency labelling, in March 2021, manufacturers returned to the previous indices from G to A, where A is the most energy efficient washing machine. Accordingly, the 2021 models will have modern markings, while older models will be marked in the same way.
Noise class
This indicator allows customers to decipher the values of the noise level in decibels. It is marked, like other classes, in Latin letters, where A is the quietest class of washing machines.
Controls
The type of controls provided in the washing machine.
— Rotary knobs. Operation through one or more rotary knobs only, without buttons or other additional elements. This option is found exclusively in semi-automatic (activator) washing machines with minimal functionality. In the simplest of these models, there is only one knob (it sets the duration of the wash) in more advanced ones — two or three (wash timer, spin timer, programme selection). At the same time, the timer knob simultaneously works as a switch, turning on the unit when turning.
—
Rotary knob + buttons. Type of control used in most automatic washing machines. The main rotary knob in such models is responsible for selecting the programme. It can be supplemented by auxiliary knobs for setting individual parameters: for example, water temperature and spin speed. And other parameters and additional functions are controlled by buttons. Such controls are quite functional and inexpensive, which led to their popularity.
—
Rotary knob + touch controls. Controls, providing a combination of a rotary knob with touch controls. The first is responsible for choosing the main programme; the second is for additional functions and parameters. Such control is somewhat more expensive than the "rotary knob + buttons" combination (see above), but this moment is not fundamental. At the same time, the touch panel gives the device a sty
...lish and technological appearance, and on the practical side, it is more convenient for some users since it does not require effort to press. In addition, it is much easier to clean the touch controls from dirt than the buttons.
— Touch controls. Control, carried out only through the touch panel, is much more expensive than the “rotary knob + touch controls” combination and therefore is used mainly in advanced level machines. Units with such controls do not have unnecessary protruding parts on the front panel, which provides not only a neat and pleasant appearance but also ease of cleaning from dirt. And in some models, the touch panel can be placed on the lid of the drum, which allows you to increase its diameter and capacity without increasing the height of the machine itself. At the same time, in some cases (for example, when choosing a programme), the touch controls are less visual and intuitive than the rotary knob, so this option is used relatively rarely.
— Buttons. Button-only controls are fully functional but generally less user-friendly and visual than a combination of buttons with a rotary knob. Therefore, this option is not popular in modern washing machines.
