When I run my dishwasher it will run for a short while (10 minutes) and then the fuse will trip in the house. When the fuse is reset the dishwasher will run for a short time and then trip again. It has worked without issue for the previous 2 years. I pulled the heating element and tested it for continuity and it appears to be functioning. Could it be the high limit thermostat?
Answer Dylan, There is a slight possibility the hi limit thermostat 661566 could be the issue, but very slight. The hi limit thermostat is a "safety" device that "opens" when the temperature exceeds 170 dgrs. It's more likely that you have a pinched or shorted wire in the harness, when power is applied to the heater circuit, there's a direct short to chassis ground and the breaker trips. You'll need to check the wires from the control board down to the hi limit and from the heater back up to the door switch, especially at the bottom of the dishwasher door, where the wires transfer from the door to the lower components under the tub.
After about 10 min. my dishwasher stops and the clean light blinks 7 times. What should I check?
Answer Hello Curt. This is a heating circuit failure. You need to check the heater, thermostat, and control board to see which part is bad. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html

Is the thermostat OEM normally open or closed?
Answer Hello Barry. Normally closed.
Just recently, we started smelling a electric burning smell from the right side of the control panel half way through a wash cycle. I opened up the control panel and I did not see any evidence of any discoloring on the circuit board. I believe that the thermal fuse is issue. Do I need to check the Heating element for a short or even the High Limit Thermostat for a short or open?
Answer John, Yes, you'll want to test the resistance of the heater element (10 to 30 ohms resistance) also check the wiring from the thermostat, and heater to the door, make sure they aren't pinched or jammed along the bottom of the dishwasher or frame. Check the thermostat for a "closed" circuit at room temperature. The most common issue is a loose or weak connection inside the junction box, on the front frame. make sure the wires are twisted together tightly and the wire nuts are installed tightly and taped off the keep moisture out of the connections.
Panel lights are not right. Replaced thermal fuse. It wont complete a wash.
Answer Hello Kerby. If some lights work, and others do not, you will need to replace the control panel on the unit.
Does the thermostat on my dishwasher have the feature to be reset?
Answer Hello Brad. The high limit thermostat will reset it self once it cools down. It does not have a manual button to reset it, thanks!
