Abstract

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.

Figure imgaf001
In the drainage system (12) of the household appliance, a filter arrangement (17) is provided, through which the process water in a first filter phase in the forward direction (20) and in a second filter phase in the reverse direction (21) is promoted. The filter assembly (17) is designed to have a lower filtering effect in the forward direction (20) than in the reverse direction (21). This allows to clean the process water.
