Abstract: A method of determining a position of a diverter of a fluid circulation system in a dishwasher appliance includes measuring a fluid pressure in a sump of the dishwasher appliance while pumping fluid from the sump into a wash chamber of the dishwasher appliance via a first component when the diverter is in a first position. The method also includes measuring the fluid pressure in the sump of the dishwasher appliance while pumping the fluid from the sump to a filter cleaning manifold when the diverter is in a second position. Based on the measured fluid pressure, the method determines whether the diverter is in the second position.

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.
