Patent ID: 8728248

Claim:
A dishwashing appliance, comprising: a cabinet defining a wash chamber for the receipt of articles for washing, the wash chamber having a sump portion, the sump portion having an opening; a pump configured for the receipt of a fluid to be recirculated into the wash chamber of said cabinet, said pump having an inlet; a first filter located in the sump portion and configured for filtering fluid from the wash chamber prior to feeding such fluid to the inlet of said pump; a second filter removably received in the opening in the sump portion and configured for filtering fluid from the wash chamber prior to feeding such fluid to the inlet of said pump; a valve located in the sump portion and positioned upstream of the inlet of said pump, said valve comprising a fixed annular portion that defines a first aperture for the flow through of fluid from said first filter; a rotatable annular portion that encircles the second filter and defines a second aperture for the flow through of fluid from said first filter, the rotatable annular portion being rotatable relative to the fixed annular portion and located adjacent to the fixed annular portion such that the first aperture and the second aperture can be selectively aligned for the flow therethrough of fluid; and an actuator connected with said rotatable annular portion and configured for rotating the rotatable annular portion relative to the fixed annular portion to determine the amount of alignment of the first aperture and the second aperture such that the relative amounts of fluid flowing through said first filter and said second filter may be selectively determined.
