Abstract
A counter-rotation wash system is provided in an automatic washer wherein the basket and agitator are reversely oscillated during a wash mode and the basket and agitator are co-rotated during a liquid extraction or spin mode. A reversing PSC motor is connected through a planetary drive to both the agitator and basket with the basket being free from restraint during the agitate mode. Reduced torque requirements and other advantages accrue.
