My wife decided to wash a mop head , and it turned into a big blob that clogged everthing up. I pulled off the the drain lines and cleaned them and the pump out, I also pulled the tub out and cleaned the tub, surround and the small gateway at the bottom of the surround out. I put it all back together and when I go to start it I get the "do" error code. The switch is working it has three positions input/no /nc I have used my voult meter to check that it is working properly. I also checked that it had 120V to the control board when the door was closed. I thought that it may be a ground issue so I combined the grounds with the main one. Same issue. I went into service mode and everthing else seems to be working. Where did I go wrong, Please help.
