Abstract

A dishwasher such as a domestic dishwashing machine has a first recirculating path for recirculating wash and rinse fluids through nozzles which spray the fluid onto food ware items in the wash chamber of the warewasher. Fluid is also circulated from the wash chamber through a soil collecting circuit which conducts fluid to a soil collector which is separate from the wash chamber and recirculating path. The soil collector removes food soil from fluid passing therethrough and holds it for discharge into the dishwasher drain system when the fluids are drained from the dishwasher.
