Abstract

A drain pump (10) for an appliance (12) includes a single, self-starting, single-phase synchronous motor (16) and a pump chamber (32) having an inlet (42) and first and second outlets (46, 48). The first outlet (46) is a drain outlet (200) and the second outlet (48) is a recirculation outlet (202). An impeller (28) is disposed within the pump chamber (32) and is selectively and bi-directionally driven by the single-phase synchronous motor (16). Rotation of the impeller (28) in a first direction (34) directs fluid (44) from the inlet (42) toward the drain outlet (200) and away from the recirculation outlet (202). Rotation of the impeller (28) in the second direction (38) directs the fluid (44) from the inlet (42) toward the recirculation outlet (202) and away from the drain outlet (200).
