ABSTRACT:
A dishwasher includes a pump assembly for establishing a recirculated wash fluid flow within a washing chamber. The pump assembly includes a housing having a recirculation portion and a drain portion. The recirculation portion includes an inlet passage, a recirculation passage and a pump mount. The inlet and recirculation passages share a common wall and open into the pump mount. The pump assembly further includes a pump having a housing, a motor drivingly connected to an impeller and a conduit having inlet and outlet portions projecting from the housing. The inlet and outlet portions are concentrically arranged within the conduit and fluidly connected with the impeller. With this arrangement, the pump unit can be readily secured to the pump mount and, during operation, draws washing fluid in through the inlet and redirects the washing fluid to the recirculation passage of the housing at approximately 180° from the inlet.
