Was an easy R&R-procedure right under the machine's llid involving the removal of just 2/external-screws at the rear of the cabinet. Next, it is IMPORTANT in order to avoid confusion, simply remove the individual hoses and elect.-wires ONE AT A TIME, transferring each such item from the old to the exact same location on the new 4-valve Assembly. Then remount the new 4-valve Assembly to the aft-wall of the cabinet. Upon subsequent close-inspection it was found that the rubber-seals of the valves were cracked and leaking sufficiently to cause the malfunction.
