DU850SWPS3 Whirlpool Dishwasher - Overview

Installed new door seal. Dishwasher still leaked. Googled the model number and then cleaned the filter at the bottom of the dishwasher, still leaked.
Verified that manifold bearing was not work. It was OK.
Found note that a plugged vent might cause leaking door. Very counterintuitive. Pried off air vent cover. Vent was thouroughly plugged with calcium deposts from steam. Cleaned these out.
Dishwasher no longer leaks.

Photograph or diagram how the wires connect to the switches before taking out the old assembly. I could have salvaged switches from the old assembly by pulling out the white pins (and avoided buying the new switch kit). There's only one way the pieces go back together, so the wire connections are the only point that required special care and attention.

The first thing I did was to investigate. I needed to find where the leak was coming from. It was leaking from just above tne door front panel, directly underneath the control panel buttons. I opened the dishwasher door, and decided to remove the door screen vent. I was covered with some offwhite fiberous, or filter like material. I thought perhaps the filter had broken down, and I ordered a new screen. When it arrived, and, although I had expected to receive a new filter with the plastic door screen, I didn't. There wasn't one to be ordered. I looked at the screen again. My problem was, that although I had considered that the substance I had thought was a filter, was instead build up of detergent, and other particals. That idea didn't seem to make sense. I didn't think it was possible for that stuff to get to the door screen. I thought, it was too far away from the dispenser and food particles. As it turned out, the buildup was, in fact, the problem. I properly cleaned the door vent, which was then fine, and I put it back into the door. There were no more leaks, that was it, and the problem was solved. As a last note however, unfortunatley, I have to return the new door vent screen that I ordered. I enjoyed solving the problem, and you all helped alot. Let's do it again sometime.
