Water consumption per cycle
The amount of water used by the machine in one wash cycle. Usually, it is indicated for a standard (universal) programme — at full load, without pre-rinsing, etc. Accordingly, in special modes, the consumption may differ from the indicated one.
The lower the consumption, the better. On the other hand, a reduction in consumption can harm the quality of the wash. So, when choosing an
cost-effective machine, you should pay special attention to the wash 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.
Dryer type
The dishwasher has a drying function. Drying can occur both due to the natural evaporation of water from the surface of the dishes (
condensation drying), and due to
turbo dry with heated air. The first option is more economical since it does not require energy. Besides, there is also an improved one —
with a heat exchanger. It provides significantly faster drying. And the recently appeared new type of drying
Zeolith combines both methods because it firstly collects residual moisture and then generates it into heat, which dries the dishes and belongs to the premium segment models. Note that not all machines can dry dishes to complete dryness; see Drying class for details.
Auto door opening
Auto door opening at the end of the programme. This function is not only convenient but also acts as an end-of-cycle signal. In addition, the open door helps to speed up drying — excess moisture escapes through it.
Door closer
The door auto-closer is responsible for “pulling” the door when closing, and in some models also when opening. The idea is that the user does not need to close/open the door completely: pull it to the right place, and then the door will be "picked up" by the auto-closer and smoothly brought to a fully open or closed state. Such a system performs two functions. Firstly, it reduces the risk of leaving the dishwasher not closed. Secondly, such a device provides a very smooth opening and closing without shock. Thus it has a positive impact on the life span of the entire device.
Energy efficiency class (new)
This parameter shows the efficiency of electricity consumption by a dishwasher. Classes are designated in Latin letters from A to G, in ascending order of energy consumption. It 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 dishwasher. Accordingly, the 2021 models will have modern markings, while older models will be marked the old way.
Noise level
It is an approximate noise level produced by the dishwasher during operation. In modern models, this parameter can range from 38 – 39 dB (muffled human voice) to 59 – 60 dB (rather a 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 important if the dishwasher is to be used at night.
Noise class
It allows one 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 dishwashers.
