Hello, I have a GE gld4560n00ss dishwasher. The other day I opened the dishwasher up to empty the dishes, and the water was up to the element. I had not noticed this happening previously, it seemed like the problem arose suddenly.
-I have tried cleaning the sump pump filter out, and found a couple pieces of plastic in it.
-I checked the drain line, and there were no issues there.
-Removed and inspected the drain line assembly.
-I tried removing the lower spray arm and starting a cycle and canceling it, but it still would not drain. (http://forum.appliancepartspros...nt-drain-completely.html)

Should I be looking at the sump pump or motor? Thanks for the input guys. Hope everyone had a Happy Thanksgiving.

I did check the flapper valve and it was working well. I checked the power to the drain motor while it was supposed to be running and it had full voltage. I have ordered another motor. I will let you know if that fixes my problems, thanks!
