Abstract (en)

The device has a filter arrangement (17) arranged at a drainage system (12) and guiding process water from a tub along a forward direction (20) in a cleaning phase and in a filter phase. The arrangement guides the process water along a rearward direction (21) in another filter phase. The filter arrangement has smaller filter effect along the forward direction than the filter effect along the rearward direction. A discharge pump (8) is operated in the former filter phase. Water level in the system is increased during the former filter phase and decreased during the latter filter phase. An independent claim is also included for a method for operating a household device.

Abstract (de)

Im Ablaufsystem (12) des Haushaltsgeräts ist eine Filteranordnung (17) vorgesehen, durch welche das Prozesswasser in einer ersten Filterphase in Vorwärtsrichtung (20) und in einer zweiten Filterphase in Rückwärtsrichtung (21) gefördert wird. Die Filteranordnung (17) ist so ausgestaltet, dass sie in der Vorwärtsrichtung (20) eine geringere Filterwirkung besitzt als in der Rückwärtsrichtung (21). Dies erlaubt es, das Prozesswasser zu reinigen.
