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?

John D for Model Number DU1145XTPQA

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.

Hi, our thermal fuse keeps blowing when we put dishwasher on heat dry. I have replaced the heating element however the old one still had continuity. What is causing the fuse to blow? High limit thermostat perhaps. Thank you for answer. Whirlpool dishwasher model DU915PWSS0

Answer Hello John. If the hi limit keeps blowing, then you will need to replace the control in the unit.

my dishwasher will not do a normal wash and will not sanitize., it will do a 1-hour wash. It takes a couple of hours to do a normal wash and the dishes are not very clean. i have checked the water temp after it has ran for a while and it is about 80 degrees. could this be a sensor? It seems like the element is getting hot.

Mike for Model Number kenmore dishwasher 665.13129k701

Answer Mike, If you have the unit on high temp wash then the temp should be higher than the 80 degrees. The normal temperature coming into unit must be at least 120 degrees. You will want to check the sensor, heater and the wires back to the control board.

Have a blinking clean light it blinks 7 times. I have reset the dishwasher by pressing normal and heated dry it resets then displays d1. I have the control panel taken apart. I'm not sure Where the dishwasher fuse is. I've metered the door latch it's ok. I don't get continuity on the detergent dispenser assembly. How and where can I test the heating element as well as the dishwasher fuse? Please help

Nathan for Model Number Gu2400xtpq6

Answer Hello Nathan. The issue you are describing is not the thermal fuse. It is an issue with the heating circuit with the unit. You need to test the heater and thermostat and if good, replace the control board in the unit. 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
