ABSTRACT:
A device and method for controlling a drainage pump of a washing machine. The drainage pump is powered by a synchronous motor that is connected to a mains voltage bus by a switch. During one or more stages of a washing program the switch is operated to apply in each half cycle of the mains voltage a delay time from the zero setting of the mains voltage to cause the motor to operate in a cut-wave mode.
