    摘要： A dishwasher for treating dishes according to an automatic cycle of operation includes a tub at least partially defining a treating chamber with an access opening, a sump fluidly coupled to the tub, and a liquid recirculation circuit fluidly coupling the sump to the treating chamber. The liquid recirculation circuit includes at least one rotating spray tube having a longitudinal body axis defining a rotational axis. The at least one rotating spray tube comprises a hollow tube having first and second opposing ends with the first end fluidly coupled to the liquid recirculation circuit and the second end comprising a drain valve. The hollow tube has a single wall and a longitudinal body axis defining a rotational axis and plurality of spray nozzles are arranged about the longitudinal body axis on an exterior of the single wall.

    摘要： A check valve assembly for a drain pump configured to transfer fluid from a sump, through a volute having a pump discharge passageway extending from the volute, includes a seat assembly and a flapper assembly. The seat assembly has a body with a first distal end and a second distal end, and a fluid passage extending through the body. The body defines a valve seat having a sealing surface about the fluid passage. The flapper assembly is operably coupled to the seat assembly. The flapper assembly has a moveable portion configured to selectively move between a closed position where the moveable portion seals against the sealing surface and an opened position where the moveable portion raises to allow liquid through the fluid passage. The check valve assembly is configured to be located within the pump discharge passageway.
