There is disclosed a dishwasher having an improved bearing and seal construction for the spray arm. The spray arm is mounted for limited vertical movement with respect to the outlet conduit of a pump. When pump pressure is applied to the spray arm, the spray arm is lifted out of load supporting engagement with the conduit and engages a seal which reduces liquid leakage around the spray arm. When pump pressure is interrupted the spray arm returns to the supported position, allowing the spray arm to drain. The spray arm is removably mounted onto the conduit to allow for servicing of the dishwasher.
