Abstract
A dishwasher is provided having a wash chamber that is supplied with wash water by a water circulation pump assembly. The pump assembly has a motor, an inlet in fluid communication with a sump, and an outlet in fluid communication with the wash chamber. A macerator system is configured with the pump assembly and includes a filter screen disposed across the inlet and a chopper blade rotationally driven by the pump assembly at a defined axial distance upstream from the filter screen. The chopper blade is biased by materials in magnetic flux communication to the defined axial distance so as to maintain the defined distance in a running and stopped states of the pump assembly.
