A combination motor-pump and soil separator assembly includes a reversible motor which drives a wash pump and a drain pump. When operated in a wash mode, the wash pump directs pressurized wash liquid to one or more wash arms. In addition, a centrifugally sampled portion of the wash liquid containing a high concentration of entrained soil particles is directed to a guide chamber. The guide chamber is in fluid communication with a soil container, which receives the wash liquid to be treated. Soilladen water received within the soil container is passed through fine filters disposed in a wall of the soil container, resulting in a cleansed wash liquid. The cleansed wash liquid is then returned to the wash pump, where additional wash liquid is added, for recirculation within the dishwasher. Upon completion of a wash cycle, the motor is operated in the opposite direction, providing a draining action within the soil collector.
