Abstract

A method for operating a dishwasher that includes a plurality of water circuits in which rinsing liquid is circulated according to a program control unit. In an exemplary method, the circulation of the rinsing liquid results in the passage of the rinsing liquid through at least one filter element that captures dirt entrained with the rinsing liquid. In response to a selected one of a program command provided by the program control unit and a detection of a defined degree of soiling of the filter element with dirt, the method includes circulating the rinsing liquid in a second water circuit in coordination with disposing the filter element in a second operating state thereof in which dirt can be dislodged from the filter element.

Claims (5)

1. A method for operating a water-conducting household appliance, the method comprising:

in the course of circulating a rinsing liquid in a first water circuit, operating a filter element in a first operating state, in which it undertakes filtration of the rinsing liquid for removal of dirt from the first water circuit; and in response to a program for directing the first water circuit and a second water circuit to circulate the rinsing liquid, circulating the rinsing liquid in a second water circuit in coordination with disposing the filter element in a second operating state thereof in which dirt can be dislodged from the filter element.

2. The method as claimed in claim 1 , wherein with the second water circuit, the filter element is operated in its first operating state, in order to rid the rinsing liquid being conveyed in the second water circuit of dirt.

3. The method as claimed in claim 1 , wherein after completion of the program, the filter element is operated in the second operating state, in which dirt located on or in said filter element is flushed out of the filter element by the rinsing liquid being conveyed in the second water circuit.

4. The method as claimed in claim 3 , wherein during the second operating state, the rinsing liquid being conveyed in the second water circuit is conducted to a water outlet.
