Dishwasher does not light up, no power to LED switches
If the model number you listed this question under is correct, 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 no longer have an owner/operator manual for your dishwasher, you can go to mangemylife.com and obtain one. Just type in your model number under the "Manuals" link and your owner's and installation manuals are available in .pdf (Adobe) format that you can download or print for FREE.
If you need a troubleshooting guide, all these appliances have a technical data sheet inside them that qualified repairmen refer to. The tech sheet includes all troubleshooting data and wiring diagrams. You can access it usually by removig the lower toe panel under the door. If its not located directly behind the panel, its usually located under the wash tub. Some manufacturers place the tech sheet behind the inner door panel.
