Abstract

A dishwasher includes a number of spray arms, a circulation pump with a pump housing, an impeller, a suction port, and a number of discharge ports on the pump housing. The discharge ports are associated with the spray arms. A water diverter is located on a delivery side of the pump and generates a flow leading from the suction port selectably to one or more of the discharge ports. The water diverter includes a blocking element having a number of diaphragm openings positionable to one or more outlet positions by a drive via a rotation of the blocking element in a circumferential direction.
