主权项

1. A dishwasher for treating utensils according to a cycle of operation, comprising:
a tub at least partially defining a treating chamber for receiving utensils for cleaning; a sump fluidly coupled to the tub and collecting liquid supplied to the tub; a recirculation pump comprising an impeller having an inlet fluidly coupled to the sump and an outlet fluidly coupled to the tub to recirculate liquid from the sump to the treating chamber; a filter having an upstream surface and a downstream surface, and fluidly separating the sump and the outlet; and at least one flow diverter rotating about the upstream surface or the downstream surface; wherein liquid in the tub collects in the sump and is recirculated by actuating the recirculation pump such that the liquid in the sump is drawn through the filter and is expelled through the outlet to the tub and the rotation of the flow diverter generates a shear force acting on the upstream surface or the downstream surface to effect a cleaning of the upstream surface or the downstream surface.
