ABSTRACT:
A dishwasher has a washing chamber having at the top a rotatable wash arm which is supplied with filtered fluid from the dishwasher pump to prevent redeposition of soil particles on the dishes. In one embodiment, the fluid is supplied when the unit is in the recirculate or wash mode at all times by bypassing a certain amount of the pump output through an external filter to the third level wash arm. Fluid is also supplied during the drain cycle as a bypass from the drain outlet. In another embodiment, the fluid is supplied only during the drain portion of the cycle.
