I just checked out a Whirlpool dishwasher where it will start a cycle, it fills with water, but as soon as it starts the main wash motor it shuts itself off. It does it consistently, tried it 3 times and it did it every time. When it shuts itself off, it shuts off the lights on the control panel. It can be started right back up, the buttons on the control panel respond properly. I'm thinking the computer is bad, but was hoping someone here can chime in with any suggestions to troubleshoot this further. I would just swap out the computer, but I don't have one in stock. Any ideas?
