Abstract
A filter device for a water-bearing domestic appliance which has a surface filter with a sleeve shape, a support structure for said surface filter and a flow-through filter housing with filter inlet and filter outlet. The surface filter is held stably on the support structure, which has through-flow openings and a central opening at the end. A first flow path for water leads into the support structure and out again through the through-flow openings and the surface filter. A second flow path leads into the support structure and out again only through the central opening. The support structure is designed circumferential and is formed by support ribs which between them comprise the through-flow openings. The surface filter is attached or pressed onto the outside of the support structure in such a way that it covers the through-flow openings and rests on the outside of the support ribs.
