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.
