Abstract

A water-using household appliance includes a pump sump, a filter element arranged at least partially in the pump sump, and a nozzle unit arranged on the pump sump. The nozzle unit produces an annular flow between the pump sump and the filter element in order to remove dirt from the filter element, with the annular flow flowing around the filter element only in one direction of flow.
