ABSTRACT:
A dishwasher sump is divided into a collection chamber and a pump chamber by a filter. Food particles collect in the collection chamber while filtered wash liquid collects in the pump chamber. The filtered wash liquid is recycled and sprayed on objects in the dishwasher. A venturi jet pump has a suction gap located in the collection chamber and an outlet connected to a drain. At the end of a wash cycle, the wash liquid is pumped through the jet pump thereby entraining fluid and particles from the collection chamber to be carried to the drain.
