Comparison Bosch SPS 53E28 stainless steel vs Bosch SPS 50E58 stainless steel

The amount of water used by the machine in one wash 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, the better. On the other hand, a reduction in consumption can harm the quality of the wash. So, when choosing an economical 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.

Possibility of connection of the dishwasher to a source of hot water. With this connection, the water enters the device already heated (unlike the usual procedure, when the machine heats the water to the desired temperature) — thus saving time and energy. However, the hot water supply is quite demanding on the quality of water: in most cases, it must have a temperature of 60-65 °C and flow without pressure drops.
Note that hot water supply is an option, not the only solution; machines with the possibility of such a connection can usually work according to the standard scheme, from a source of cold water.
