Abstract

A dishwasher is provided with a fluid handling system that utilizes two separate sumps and two separate pumps. A first sump receives a portion of the wash liquid from the wash chamber and recirculates the wash liquid by use of a relatively high capacity pump in the first sump. The second sump receives the remainder of the wash liquid and removes both heavier-than-water and lighter-than-water soils before directing this remainder of the wash liquid to the first sump. A relatively low capacity pump in the second sump directs wash liquid and collected soils to an exterior drain.
