ABSTRACT:
A dishwasher having a fluid recirculation system which operates in a wash mode for spraying liquid onto objects supported on dishwasher upper and lower racks. The dishwasher includes a pump having a pump impeller disposed within a pump chamber for supplying wash liquid to first and second spray devices, associated with the lower rack and upper racks, respectively. The pump impeller draws wash liquid into the pump chamber and imparts a rotary motion to the wash liquid disposed in the pump chamber. A rotatable diffuser or flow director having a plurality of vanes extending into the pump chamber selectively directs the rotating wash liquid toward the spray devices and thereby controls wash liquid recirculation within the dishwasher responsive to the rotational motion of the wash liquid in the pump chamber.
