Abstract

A dishwasher having a washing compartment for items to be washed and a first circulation circuit to subject the items to a washing liquid. The first circulation circuit includes a circulation pump; a water heater; and a spraying device. The washing liquid is routed from the washing compartment to the pump and fed back into the washing compartment. A second circulation circuit has the circulation pump, the water heater and a mixture store with input and output openings. An output side of the pump has a branching point that flow controllers are assigned to to allow the washing liquid to circulate in the first circulation circuit and/or the second circulation circuit. In the second circulation circuit, the washing liquid is routed from the washing compartment to the pump, pumped into the mixture store via the input opening, and fed back into the washing compartment via the output opening.
