Charles H Bellevue , WA March 07, 2018 Appliance: Jenn-Air Dishwasher JDB8700AWS0 Jenn-Air Dishwasher Jdb8700aws0 / : Dishwasher controls would not work. How to replace Electronic Control Board (Main). Purchased the Electronic Control Board and the Control Panel (was no sure which was bad). Installed the new parts purchased from AppliancePartsPros.com. Installation was easy and the parts fit perfectly. After the installation turned on the unit and it works fine now. Since I could not tell which unit was bad, I used the rule of thumb to replace both since electronics can be tricky and if one component can go bad you can bet the other may also at some point. Did note that the Electronic Control Board was just hanging loose. Appears that the factory did mount it correctly or during transportation and professional installation if came loose. This may have contributed to the problem. 3 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
