Water consumption
The amount of water used by the dishwasher in one washing cycle. Usually, it is indicated for a standard cycle — at full load, without pre-rinsing, etc. Accordingly, in special modes, the consumption may differ from the indicated one.
The lower the consumption — it better; this is especially true for those who consume water by metres or who have a limited supply of water (for example, it is drawn from a well with a low productivity). On the other hand, a reduction in consumption can have a negative effect on the quality of the wash. So, choosing an
economical dishwasher, you should pay attention to the washing class (see below). In addition, only models of the same capacity can be compared in terms of consumption — after all, the more dishes, the more water is required to wash them.
Energy class (new)
This parameter characterizes the efficiency of electricity consumption by a dishwasher. Classes are denotet in Latin letters from A to G, in ascending order of energy consumption. Actually, more energy-efficient models have not been added to the A class, which eventually received the marking A +, A ++, A +++. Further development of technology has made it possible to go even further, and in order not to produce pluses in energy efficiency marking, manufacturers returned to the previous indices from G to A in March 2021, where
А is the most energy efficient dishwasher. But also
class B,
C,
D and even
E are also quite economical (no worse than A +++). Accordingly, the 2021 models will have modern markings, while older models will be marked in the same way.
Noise level
The approximate noise level produced by the dishwasher during operation. In modern models, this parameter can range from 37 – 39 dB (muffled human voice) to 59 – 60 dB (loud conversation); more detailed decoding of what sound corresponds to a particular number of decibels can be found in special tables. Anyway, the
low noise level contributes to the comfortable use of the device. It is especially important if the dishwasher is to be used at night (for example, if there are reduced electricity rates at night).
Noise class
Allows people to decode the values of the noise level in decibels. It is marked in Latin letters like other classes, where A is the quietest class of dishwashers.
