Abstract
Abstract An annular cover mounted on top of a clothes washer outer tub and extending inwardly over the clothes basket to contain the splashing of water created by the action of the agitator and to safeguard any overflow onto the base of the cabinet created by a defective water level switch or faulty timer or water valve, the cover having an annular rim engaging the outer tub, and a vertical wall terminating in an inwardly extending downwardly sloping annular flange and having an opening in one side leading into a well externally on the tub and a hose securely fastened to this well externally of the tub whereby in a high water condition the trough and hose will create a siphon thereby maintaining a safe water level before it overflows the cover onto the base, the hose fits through a hole in the base or cabinet of the washer.
