Abstract

A dishwasher appliance is provided having a fluid circulation assembly that uses a single motor and a common drive shaft to rotate both a wash pump impeller and a drain pump impeller. The wash pump impeller and the drain pump impeller are separated by a filter to prevent food soil from being circulated by the wash pump impeller. The common drive shaft passes through an aperture in the filter, the aperture being sealed to prevent the passing of food soil by an inlet guide assembly. The inlet guide assembly includes an upper inlet guide and a lower inlet guide that define a clearance bore and a washer chamber. A washer is positioned in the washer chamber to prevent the flow of food soil through the clearance bore.
