    Patent number: 9609996
    Abstract: In a method for pumping a fluid out of an aquiferous household device such as a dishwashing machine, a drain pump and a circulation pump are operated at least partially simultaneously to ensure that, in the event of an abrupt stop of the circulation pump, reverse flow that may cause filter cake formed by separating soiling and particles to loosen resulting in their re-soiling of the items to be cleaned. The speed of the circulation pump is lowered from a maximum speed to at least a minimum speed substantially without pressure surges before startup of the drain pump.
