Replaced both the mixing valve and the flow meter, after examining both found that the flow meter was the culprit. Decided to save the pressure switch for later repair; but the amount of calcium on top of the soap dispenser was like a limestone cave (leak in line from flow meter). Also the mounting ear on the water mixing valve didn't line up with original sheet metal hole so I had to drill a new one. Cleaned out the Pump filter and the drain line was almost 1/2 clogged with sludge. Purchased this Duet set in 2008. I also adjusted the original pressure switch water level screw and now I am getting wash loads that are finally free of soap. The water in AZ is very high in calcium and I don't have a soft water loop so I will be substituting Borax in every load from now on. I spent most of this repair time fine tuning the water level so that the drum fills enough for the water to fully flow through the clothes. I also ran 6 loads with the cover off to ensure there were no leaks because all the lines were disconnected so I could flush them out. This unit is working better than it did when it left the factory.
