It includes supplemental liquid collecting means disposed in a flow path separate and upstream of the soil-collecting means and operative to channel an additional quantity of recirculating washing liquid to the soil-collecting means. Drain means removes the washing liquid and the filtered food soil from the receptacle during the drain cycle.
