Abstract

A dishwasher incorporating a food waste disposal system and has a sump formed in its lower portion and a drain pump located in the sump is provided. The drain pump includes a motor driving an impeller and a chopping blade. A fine filter is positioned before the inlet portion of a wash pump in the sump to collect and concentrate food particles held adjacent the drain pump. An electronic controller, which controls the dishwasher cycle and the wash and drain pumps, causes the chopping blade to rotate and chop any food particles held adjacent the drain pump. An electrically controlled valve, operated by the electronic controller, is in the drain line of the drain pump and can be pulsed on and off during operation of the dishwasher to allow removal of some food particles in the wash water at any intermediate point of the cycle.
