Abstract
An improved wash tube is provided for a dishwasher. The wash tube is mounted on the upper rack and has a first end adapted to be releasably docked with the water manifold in the back of the dishwashing chamber as the rack is moved between the extended loading position and the retracted wash position. The inner end of the wash tube includes a curved cap which increases the docking tolerance and which presents a substantially downwardly oriented water inlet to the wash tube. The cap creates water stagnation adjacent the inlet such that the water velocity is substantially reduced and the pressure increased. The second end of the wash tube is connected to the spray arm which rotates as water is ejected from the spray arm nozzles at increased pressure. The cap allows the wash tube to fully dock into the manifold without obstructing the water inlet.
