Abstract
A pump for an automatic washer is provided which has an inlet connected to the machine tub and a first outlet connected to a set of dispensing chambers and a second outlet connected to a drain, and including a check valve between the inlet and the second outlet such that when the pump is rotated in a first direction, liquid is drawn from the tub through the check valve and pumped by the impeller to the first outlet. The first outlet is selectively openable and if opened by a solenoid controlled valve, allows a flow of liquid to the dispenser chambers. Rotation of the impeller in the second direction closes the check valve and allows the flow of liquid from the machine tub to the drain.
