After nearly 2 hours of looking, Mr. Appliance finally discovered that the rubber manifold to the upper spray arm had a big hole in it. The replacement manifold is plastic, not rubber, and requires that the upper spray arm be replaced also. There are two screws holding the manifold and spray arm to the upper rack. It' will save you time if you only unscrew the bottom screw! The bearing for the lower spray arm was badly worn allowing the arm to wobble. This wobble might been the major problem related to water leak. Excessive wobble can create an unwanted wave action in the dishwater, causing water to leak under the front door. The bearing was very easy to replace. I also ordered a new pump outlet seal, but did not install it since the dishwasher works like new and doesn't leak water anymore. While checking earlier for possible leaks, the lower front panels were removed. The sound insulation on one of the panels was wet due to water leaking under the door. Reinstalling the panels, after allowing the insulation to dry, was the hardest and most time consuming part of the repair.
