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 (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.

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.
