Dishwasher filter back-wash system independent from lower wash arm

摘要

A soil separator and water distributor for a dishwasher having an annular screen facing into the dish compartment for screening wash water, and a rotating flush arm above the annular screen for flushing soil from an underside of the screen, and a separate wash water arm above the flush arm for spraying the dishes. The wash water arm can thus be flow separated from the flush water arm. Thus, the wash water arm can be operated intermittently while the flush water arm can be operated continuously.
