An impeller for a pump for a dishwasher having a base with an axis of rotation, and at least one fin protruding from the base. The impeller also has a cap removably coupled to the impeller and at least one blade integrally formed with the cap.

A waste water pump includes an impeller (12) and a surrounding pump housing (4), wherein an impeller side chamber (20) is formed between the impeller (12) and the pump housing (4). The impeller side chamber (20) has a first seal (16) between the impeller (12) and the pump housing (4), towards the intake side (32) of the impeller (12), and a second seal (18) between the impeller (12) and the pump housing (4), towards the pressure side (14) of the impeller (12). The first seal (16) is provided with a conveying device (28, 30) configured to convey debris from the impeller side chamber (20) to the intake side (32) of the impeller (12). The second seal (18) is provided with conveying device (38, 40) configured to convey debris from the side chamber (20) to the pressure side (14) of the impeller (12).

A dishwasher comprising a chassis, a tub supported by the chassis and at least partially defining a treating chamber, and a pump that circulates wash liquid in the treating chamber. The pump has an impeller that has a cover, a base with an axis of rotation, and at least one fin protruding from the base. The impeller also has a cap removably coupled to the impeller and at least one blade integrally formed with the cap.

A universal pump assembly mounts, interchangeably, on a canned motor or on an adapter having an outer magnet assembly rotated by a motor. The pump assembly has a casing with an inlet and an outlet, and an impeller rotatable within the casing to pump fluid from the inlet to the outlet. The pump assembly can have either a mounting ring for attachment to the canned motor, or a containment shell having a cup with an inner magnet assembly and a mounting ring extending from the cup for attachment to the adapter. Mounting features of the mounting ring may be threaded holes or internally threaded posts as non-limiting examples.
