ABSTRACT:
A bidirectional pump has a chamber in communication both with a drain conduit and a conduit for delivering washing liquid into a wash chamber. The drain conduit has a port communicating between the pump chamber and a drain outlet. An opening communicates between the delivery and drain conduits and is selectively sealed by a deformable diaphragm. With the pump rotating in a first direction and the liquid being delivered principally through the delivery conduit by the pump, a pressure differential is established across the diaphragm thereby urging a portion of the diaphragm sealingly against the port to prevent delivery of washing liquid through the drain conduit as during a rinsing cycle of the dishwasher. Reverse rotation of the pump reverses the pressure balance to urge the sealing portion of the diaphragm away from the drain port, thereby permitting flow through the drain conduit for suitable disposal of the used washing liquid.
