Abstract

A household appliance includes a circulation pump for circulating dishwashing liquid in a washing compartment of the household appliance. A drain pump empties the dishwashing liquid from the washing compartment. For the purposes of ventilating the drain pump, a control device is provided to activate the drain pump after the washing compartment has been filled with the dishwashing liquid and before or during operation of the circulation pump.
