Abstract: A control board assembly including a control panel and a carrier plate which have alternatively occurring tab and hook members. The tab and hook members of the two elements can be overlappingly engaged to prevent movement of the carrier plate with respect to the control panel. The carrier plate is further comprised of a face plate which is adapted to receive one or more circuit boards held in parallel orientation by rails. When the carrier plate is slidably moved to an engaged position with the control panel, the carrier plate can be locked against further movement by an integral catch or by attaching one screw which extends through the carrier plate and threadably engages a bore located on the control panel.

Abstract: The present invention is directed to a two chamber dishwasher pump wherein the pumping noise associated with recirculation is substantially lowered by reducing the intake area to the recirculation impeller thereby interrupting air pockets formed in the fluid while recirculating. In addition the noise associated with fluid drainage is minimized by an aperture between the drain chamber inlet and the drain outlet which allows fluid to flow from the inlet to the outlet thereby interrupting air pockets in the drain line which create the noise. In addition, fluid flows through the aperture in an opposite direction to that described above in order to relieve excessive pressure in the drain line during recirculation.
