(54)	Feed system for a middle-level spray arm

(57) A washer having a tub with a side wall, a top wall and a rear wall. The washer defines a wash chamber having upper and lower racks disposed therein. A valve alternately provides pressurized wash liquid to a lower spray arm disposed below the lower rack and a middle-level spray arm disposed below the upper rack. A middle-level feed system conveys liquid from the valve to the middle-level spray arm. The middle-level feed system includes a side feed tube connected by a spray nozzle to a rear feed tube. The rear feed tube extends rearwardly along an interior surface of the top wall, then downwardly along an interior surface of the rear wall and then forwardly underneath the second rack. The rear feed tube supports the middle-level spray arm underneath the upper rack.
