There is provided a filter device that enables less frequent manual or self cleaning of the filter surface. The filter is particularly suitable for an aquiferous domestic appliance, such as a dishwashing machine, in which the cleaning effect occurring with alternating pumping is further increased, such that manual cleaning of the filter surface need take place less often, or, respectively, self-cleaning of the filter surface occurs.
1. A filter device, for use in a dishwasher comprising: at least one filter body with an influent filter surface and an effluent filter surface, the filter body being operable to filter aquiferous material that moves through the filter surface between the influent filter surface and the effluent filter surface with the influent filter surface being configured to resist adhesion of contaminants thereto, wherein both the influent filter surface and the effluent filter surface are configured to resist adhesion of contaminants thereto, and wherein the influent filter surface and the effluent filter surface are at least partially coated with diamond-like carbon.
