Abstract
A dishwasher functions to chop all fluid entrained soil prior to directing fluid to at least upper and lower wash arms and directs a percentage of the fluid flow into a filter chamber having one or more fine mesh filter screens that open into the dishwasher tub basin. When the fine mesh filter becomes clogged, fluid is forced to flow up an overflow tube and be exposed to another filter. The draining of portions of the system are sequenced to enhance soil removal.
