Abstract

A household dishwasher includes a washing container having a floor, and a spray arm supported for rotation about an axis of rotation and including spray nozzles for applying washing liquor and/or fresh water to a dishwasher load received in the washing container. The spray arm is designed so as to be capable of being disassembled and re-assembled along the axis of rotation, in order to transfer the spray arm from a first mode, in which the spray nozzles point away from the floor, into a second mode, in which the spray nozzles point toward the floor, and vice versa.
