ABSTRACT:
A self-aligning water jet receiver for a rotary spray arm rotatable about an axis of rotation on a dishwasher dish rack in which the rotatable spray arm is mounted on the dish rack and is rotated by the reaction force of water exiting through spray nozzles in the spray arm. An upwardly projected water jet supplies the water to the hollow spray arm. In this invention the liquid jet is received in a jet receiver that is mounted on the spray arm along the axis of rotation and is shiftable laterally by the force of the jet on the receiver to align the receiver coaxially with the jet.
