Abstract

A water-bearing household appliance 1 which serves, in particular, as a laundry treatment unit for washing and / or drying laundry comprises a treatment region 3 which is surrounded by a container 2, a pumping-away section 9 which is connected to the treatment region 3, a discharge pump 10 which is arranged in the pumping-away section 9, a filter device 20 which is arranged in the pumping-away section 9, and a water storage tank 12 which is connected to the filter device 20 via a pump 25. By actuation of the pump 25, water can be branched off into the water storage tank 12 from the pumping-away section 9 via a filter 22 of the filter device 20. The water which is stored in the water storage tank 12 can replace part of the supplied fresh water in the case of a further programme run. The embodiment of the filter device 20 makes self-cleaning of the filter 22 possible.
