ABSTRACT:
A controlling device controls the operation of a clothes washing machine having a tub, a washing liquid collector, a heating element and two thermostats within the collector, and an electric pump for circulating the washing liquid from the collector to the tub. Three pressostats or pressure switches allow washing liquid to be filled to two different levels in the machine and for controlling the working condition of a filtering element within the collector. The controlling device allows both "intensive" washing programs with only a low level of liquid in the collector and "delicate" washing programs with normal levels of liquid in the tub. Different types of laundry can be washed under the best conditions with low consumption of water, detergents and electric power.
