I have a Whirlpool dishwasher and it keeps turning off mid cycle. The lights on the panel stop working. When I replaced the thermal fuse it works for about 20 minutes and then the dishwasher stops working. I have replaced the thermal fuse a few times and it will not go to the end of the cycle. I also replaced the thermostat and that didn\'t fix the issue. Please let me know what it can be.
