Well here is another guy struggling with same OE error code . After it came up first time (4 years after we bought the dishwasher) I checked the filter and drain hose where it connects to garbage disposer. There was a small piece of plastic stuck at the junction and filter was pretty dirty. I removed obstruction and cleaned the filter but the code kept coming up . As of now it stops the washing cycle and leaves some water on the bottom of the dishwasher. When I press normal and delicate button together the drain pump kicks in and expels the water out. So since water is coming out I don't think the drain is plugged. any more. So my next mission was to check the drain pump. Since I don't have a new pump yet I didn't feel like pulling the unit all the way out so I tried to remove the drain pump and casing from below. I took the plate off and noticed that pump is accessible. It was a challenge to work around it with very little space. To take it out I had to take off two clamp. It took me a while but I managed...
