ABSTRACT:
A dishwasher is provided with a valve for alternating flow to upper and lower spray arms during washing. The valve is controlled by periodic interruption of the pump for certain lengths of time. An electromechanical timer has a main cam wheel and an auxiliary cam wheel. The main cam wheel controls the pump and other parts of the dishwasher. The auxiliary cam wheel overrides the main cam wheel control of the dishwasher to provide the periodic lobes.
