Abstract: 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.

Abstract: A dishwasher having a tub and spray arm assembly for a dishwasher having a spray arm assembly for spraying wash liquid in the tub. The spray arm assembly has spray arm inlet, a bearing assembly with a bearing body that defines a through passage with a bearing inlet and a bearing outlet fluidly coupled to the spray arm inlet. The spray arm assembly also has a liquid supply conduit with a supply outlet fluidly coupled to the bearing inlet, a seal positioned between the bearing body and the liquid supply conduit; and a deflector provided within the supply outlet to effectively divide the supply outlet into at least two portions. At least one of the two portions faces upstream and defining an effective cross-sectional area confronting the bearing inlet that is less than or equal to the cross-sectional area of the bearing inlet. The deflector is also aligned with the bearing inlet and defines a turn in the supply outlet for directing liquid into the bearing inlet.
