ABSTRACT:
An overflow control unit for a washing machine which interconnects the drain hose of the washing machine to a stand-pipe is provided which comprises a cylindrical plug device having a central axially extending passageway therethrough and a by-pass valve interconnecting the passageway of the cylindrical plug with the atmosphere, the by-pass valve having an open and a closed position. In one embodiment the overflow control unit is operatively connected to a pressure switch so that upon a build-up of water pressure within the stand-pipe due to the drain being obstructed the switch is activated to break the electrical circuit to the washing machine.
