Abstract: A dishwasher includes a plurality of electrical wash system components connected to a control system constituted by a user interface controller and a main controller. The user interface controller includes a plurality of user input selectors for establishing model dependent operational parameters for a washing operation. The main controller broadcasts an information packet regarding a desired washing operation in the form of a first set of instructions associated the model dependent operational parameters and a second set of instructions associated with other dishwasher models. The dishwasher is then operated based upon the first set of instructions, while the second set of instructions are automatically filtered out.

Abstract: A multi-compartment dishwasher includes first and second washing units defining corresponding first and second washing tubs or chambers. The dishwasher also includes first and second control boards operatively associated with the first and second washing units respectively. Preferably, the first and second control boards are joined by a communication link that serves as a conduit for sharing data. The dishwasher further includes at least one ID designator that identifies one of the first and second washing units as a primary washing unit and the other of the first and second washing units as a secondary washing unit. The primary and secondary washing units share certain system resources during an overall washing operation, with the primary washing unit having preference over the secondary washing unit.
