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.

Abstract: A dish treating appliance has a tub at least partially defining a treating chamber for holding dishes for treatment according to an automatic cycle of operation. An access opening provides access to the treating chamber. There are multiple sprayers that emit liquid into the treating chamber, multiple feed tubes fluidly coupled to the multiple sprayers, a diverter valve selectively fluidly connecting to the multiple feed tubes, and a pump having an inlet fluidly coupled to the treating chamber and an outlet fluidly coupled to the diverter valve.
