The water diverter includes at least one blocking element, a drive element driven together with the electric motor of the recirculation pump and configured to move the at least one blocking element, and a transmission disposed between the blocking element and the drive element. The transmission is configured to convert a continuous movement of the drive element into a discontinuous movement of the blocking element.
