Abstract

A dishwasher, in particular a domestic dishwasher, having at least one substantially closed water circuit in which washing liquor is recirculated in a first direction in accordance with a program control unit, with the washing liquor being conveyed through a filter element during recirculation in order to filter impurities. Provision is made of a device for reversing the direction of flow, and this allows recirculation of the washing liquor in a second direction, which runs counter to the first direction, in order to flow through and eliminate impurities from a first screen, with the first screen being arranged in the water circuit in such a way that liquid forcibly flows through the first screen during recirculation of the washing liquor both in the first and in the second direction.
