Abstract

Described is an automatic washing machine comprising a laundering tub and a drum mounted therein and adapted to be rotated by an electric motor at a low speed during a laundering cycle and at an increased speed during at least one intervening spin-drying phase. For avoiding the excessive formation of foam, a pressure switch is adapted to terminate the spin-drying phase when the pressure within the laundering tub exceeds a predetermined value.
