hi, my dw is flashing "er, clean, S, washing drying", and when the doors shut some motor runs but nothing happens (no water is filling the dw). a repair guy said that after talking to the 1-800-number given on the dishwasher that the controal board needed to be replaced. so App. Parts Pros. sent me one witch I have installed. after installing it nothing seems to have changed. any suggestions? thank you for any advice!

thanks for the link. so I have removed the lower panel. and that motor running, I had mentioned befor turns out to be the drain pump motor. I am not sure why it would be running as there is no water in the dishwasher.
