Abstract
A dishwasher is provided with a flapper valve for directing water from a recirculation pump to spray arms or a drain. The valve is spring biased toward a recirculate position and solenoid operated to a drain position. An inlet of the pump is provided with a downwardly curved suction pipe having a generally horizontal bell mouth. The dishwasher has a sump separated into a pump chamber and a collection chamber. The pump inlet is located in the pump chamber and has a mouth that is located below a level of the bottom of the collection chamber. Wash liquid is pumped through a venturi in the collection chamber to a drain.
