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.
Direct drive
In machines with
direct drive, the rotation from the engine is not transmitted through a belt drive, but the drum is located directly on the motor shaft. Such a design produces less noise and vibration. In addition, it is considered more reliable — manufacturers give a guarantee of up to 10 years for the drum and engine of such machines.
Inverter motor
Washing machine with an
inverter electric motor.
Such motors are also called brushless because they do not have commutator brushes. Thanks to this feature, the noise level, heating and wear are significantly reduced, which has a positive impact on efficiency, reliability and durability. In addition, the accuracy of rotation speed control is increased. The reverse side of the coin is the rather high price of such machines.
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.
Direct injection system
Auxiliary system designed to ensure uniform and intensive contact of the detergent with the washed laundry.
In machines without direct injection, contact occurs only at the bottom of the drum. It is believed that this does not always provide sufficient uniformity. To eliminate this drawback, a
direct injection system was created: a special pump delivers a detergent solution through a nozzle at the top of the drum. It increases the washing efficiency and also contributes to savings — with the same result, less powder is used.
Surge protection
Power surge protection automatically turns off the washing machine in case of power surges. It protects the device's electronic circuits from hazardous loads and prolongs their service life. In this case, the programme running at the time of shutdown is remembered. And when the power is restored washing cycle continues from the point at which it stopped.
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.
Noise level (spin)
The maximum noise level produced by the machine during operation. Most often indicated for spinning — this is the noisiest mode of operation; for units without spinning (such as semiautomatic devices), this paragraph indicates the overall volume or the volume in the noisiest mode.
The
quieter the machine works, the more comfortable it is for others. This moment is especially critical if there are small children in the house. However, the decibel used to measure loudness is a non-linear unit, and the actual noise level is best estimated from comparative tables in special sources.
Dimensions (HxWxD)
General dimensions of the washing machine in height, width and depth.
The size of the unit determines not only the size of the space required for installation but also the ability to bring it into a particular room. At the same time, even a relatively small protruding part (like a door latch) can create problems with passing through a doorway. Therefore, in our catalogue, we try, if possible, to indicate exactly the maximum size of the machine — taking into account all the protruding parts. On the other hand, not all manufacturers provide such data. So if there is any doubt, it is worth evaluating the product by size with a certain margin. And specific information on how the dimensions were measured can usually be found in the manufacturer's documentation.
Finally, let's touch on the specifics of individual dimensions. So, in the case of front loaded machines, note that additional space in front inevitably will be required to open the door. Machines whose depth
does not exceed 40 cm are considered narrow. They can be a lifesaver in cramped conditions, especially if the design provides top loading. And a height of 120 cm or more is an almost unmistakable sign of
a machine with 2 drums which are located one above the other. It does not only increase capacity but also allows you to simultaneously wash two sets of things in different modes. The reverse side of these advantages is traditional
...— high cost.
