Abstract

The mechanical performance acting on the washing located in the drum is determined from the power consumption of the electric motor via a stored characteristic curve specific to the drum. The temporal cycle of the program is designed in such a way that the washing or a predetermined proportion of the washing is consistently subjected to the same presettable mechanical energy.
