I tested the Atc. mid level switch, with my multi tester and found it was not sending enough current to the cold water inlet valve, so it would not open and let cold water in. I replaced the switch, (it was a snap) literally it snapped in place. replace the front face and turned the water back on and plugged in the washer, and turned it on. It worked perfect and has been since. good and easy repair even for a novice like me..
