The complaint was that the dishwasher had power and lit up but wouldn't wash the dishes. I was a little worried because I couldn't get a service manual before I left but I thought I could troubleshoot it anyways. While the customer was struggling to pry off the 4 inch wide oak trim so I could get the kickplate off the machine I thought I would look under the sink and check the water line. After I OPENED THE WATER VALVE the dishwasher worked like a champ. He called himself a dumbass, we both laughed and he wrote me a check. Easy Money.
