Abstract
The invention relates to an automatic laundry washer of the type having a laundering tub in which a drum is rotated by an electric motor at a low speed during a laundering phase, and at a high speed during at least one certrifuging period. For ensuring a complete discharge of foam and lye in the course of a centrifuging period, a pressure switch is adapted to interrupt the rotation of the drum during the centrifuging period and to disconnect the power supply to the program control unit in response to the level within the laundering tub exceeding a predetermined value.
