Control Board Replacement part 8051136 KitchenAid Dishwasher Repair

I have listed COMMON problems / reasons why a dishwasher won't start..
The thermal fuse might have blown. The thermal fuse helps to prevent damage to the dishwasher by turning off power so that it doesn't overheat. Once blown, the thermal fuse will have to be replaced for the dishwasher to work. The thermal fuse is usually located in the control panel on the control board or mounted to the bottom of the tank behind the lower panel. The thermal fuse can be checked for continuity.
The door switch, or switches, are sometimes called interlock switches. The door switch prevents the dishwasher from running while the door is open. If the dishwasher won't start, the switch or switches might be defective. To access the door switches, remove the control panel or inside door panel - depending on the model. They can be tested for continuity.
If the dishwasher does not start, the door latch assembly might be defective. These are normally made of plastic and cannot be repaired. If the door won't latch and the door latch is broken, replace it.
The main control board provides power to nearly every component of the dishwasher. If the dishwasher won't start the main control board might be defective. You should first check for more common parts. Many times control boards are replaced unnecessarily because the problem was not diagnosed properly.

there is thermal fuse, Hi limit, and thermistor. the thermistor should have continuity at room temp I don't know what resistence(ohms) it should have. Most units I have seen provide a schematic and trouble shooting guide taped under the control panel for service personal.

sounds like you have a bad control board on unit.and the reason the thermal fuse went out is one of the relays are getting stuck on unit. before long the fuse will go bad again when the resistance level gets to high again. i would replace the control board and you should be fine...good luck to you...

Hi,
Check the control board... if your lucky the board has a fuse in it that blew... if not then the board is fried...

There is a thermal fuse (also known as a bi-metal) located inside the control panel of the dishwasher. The part number for the thermal fuse replacement is W10258275.

If you type in your model number you can utilize the exploded view parts diagrams at pcappliancerepair.com, appliancepartspros.com or searspartdirect.com to assist you in locating the part. The fuse is listed as item 6 under the "Control Panel Parts" section.


To replace the fuse, follow these steps:

1. Make sure the dishwasher is unplugged or the breaker is turned off.

2. Open the door and remove only the top screws directly behind the control panel.

3. Remove the protective cover from back of the control panel to expose the main control board.

The thermal fuse should be mounted to the control board. If you remove it and take a resistance check, it should read close to 0 ohms, if good. If bad, replace as necessary.

If you have any questions about this repair, or require additional assistance, please let me know. I hope this helps you.

That model has an electronic thermal fuse that clips onto the control board housing. the dishwasher will not start if that fuse is blown. you can check it if you have a meter. If it has continuity through it, its good, if no continuity, replace it. They cost between $20-$30. If that is not the problem, I would be looking at that motor. Kitchenaid makes a great dishwasher, but I can't count how many motors I've had to replace in them. Hope this helps, good luck.

There may be a thermal fuse located on the electronic control board housing that may have failed.This replaceable part (gray or white) is clipped on to the side of the housing. It will not look like the type of 'fuse' you may be accustomed to. It could be a round or bullet style.

You should check the thermal fuse problem listed elsewhere on this site. My power went out on mine, and it was a cheap {less than $20 part} that snaps into the control panel. It eventually blew again a month later, and I replaced the heater element, and the new heater element came with a new board that was very easy to install. the new programming on the board actually speeds up the cycle due to a higher wattage heating element.

But what I didn't do the first time was replace the wires going to the thermal fuse that came with the replacement kit. (Apparently the OEM wires are too thin) Had I done that, I probably never would have tripped the fuse again and not bought the new heater element.

Check your thermal fuse. The fuse is located inside the control panel on or near the main control board. It will be a bullet shaped component mounted with a white plastic clip with two wires leading from it. The fuse should read a short if good. Now...keep in mind, if the fuse blew it is usually for a reason. Replacing it may or may not correct your problem. In some model dishwashers there was a thermal fuse kit that was required to be installed which involved cutting the wires and using a wire splice to connect the new fuse. It seems that there was a design flaw where the gauge wire used in manufacturing would cause the thermal fuse to blow prematurely due the wire overheating. I can't remember if this applies to KitchenAid, but I believe it does. You may inquire about this at your local parts store. I hope this helps you.
