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.
Total number of programmes
The number of washing programmes (modes) provided in the machine. These programmes may differ in duration, exposure intensity, water temperature, dish material (e.g. for delicate dishes), etc. For more information on the different options, see "Programmes". Note that with the same number of programmes, their specific set in different models may be various. These details should be clarified separately.
Delay timer
A timer that starts the machine at a user-specified time eliminates the need to do this manually. This function is useful, for example, if the electricity tariffs during the day and at night are different. You can save on electricity bills by setting the start of washing at night.
Rinse aid indicator
Indicator, signaling the remaining rinse aid — a special agent used when rinsing dishes. The way such an indicator works may be different: in some models, it only signals that the rinse aid is almost over; in others, it more or less accurately displays the remainder. However, this function makes life easier for the user, allowing you to control fairly accurately the amount of rinse aid.
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.
