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.
Leak protection
An automatic safety system that controls the integrity of the system for supplying and draining water to the washing machine and stops the water supply in the event of a leak. The protection can be installed on the hoses, on the body, or both (full protection).
Leak-proof hoses are equipped with special sensors and solenoid valves at both ends that shut off the water supply in the event of a breach in the hose. They can be used for both sampling and draining water. It is worth noting that for most washing machines, leak-proof hoses can be purchased separately, even if they are not included in the original package.
Protection of the body of the washing machine is carried out using sensors installed on the bottom of the device isolated from water. When water enters the bottom, its supply to the machine is turned off. The presence of leak protection allows you to avoid troubles like a short circuit or a flood in the house. However,
leak-proof machines are more expensive than conventional machines, all other things being equal.
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.
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.
