摘要

The method involves pumping washing items into a washing chamber (13). Washing liquid quantity is pumped-down from the washing chamber. The liquid quantity is selected for achieving desired temperature in the washing chamber and for washing-out remaining liquid quantity in a continuous-flow heater (3) during a preceding heating process. An inlet shut-off unit (30) is closed at an inlet (27) of the washing chamber during the heating process, when the remaining quantity is pumped into the washing chamber. An independent claim is also included for a timed washing system.
