I have a 3 year old Kenmore Ultra wash with a middle spray arm that hits the horizontal manifold (#6). All of the parts are intact and there appears to be plenty of pressure from the pump. The probe tube (#9), which feeds water to the manifold for the middle wash arm, lifts out of the tube holder (#7) as it enters the rear feed tube assembly (#1) when the dish rack is pushed into the dishwasher.

Both the tube holder and the spray arm mount are fine. As the upper rack is seated, the probe tube gets lifted up about 1/2 inch out of the tube holder which raises the manifold just enough for the spray arm to hit it. Since the holes (1 for each position on the upper rack) in the rear feed tube cannot be adjusted, it looks like the upper dish rack or at least the height of the spray arm, has to be raised so the arm stays level when the rack is pushed in.

The rack rollers are fine, although there is a fair amount of play in the rollers.

Wondering if a new tube holder or manifold would fix this.
