Brady for Model Number GU2431XTSS2 Starting about 2 weeks ago I started to smell burnt electronics and opened up the panel to see if I could notice anything amiss. I could find no evidence of darkened circuits but the smell was coming from the circuit board. I put it back together and it worked fine with no noticeable smell. Last night it died altogether and now nothing works, no lights, nothing. I've tried the reset option with the sani and dry buttons, and confirmed continuity across the thermal fuse. Do you agree that it is the circuit board? Thanks in advance.
Answer Brady, Could you verify the model number. I could find no parts or service information with the model number you supplied. With your style dishwasher, you should first check and make sure you have a polarized, grounded 120 VAC power supply to the dishwasher. Check and insure there are no loose connections at the junction box, or the thermal fuse. Then, reset the control " SERVICE DIAGNOSTICS CYCLE NOTES NOTE 1. To invoke the Diagnostics Cycle, perform the following key presses or actions in less than 6 seconds while in standby: Heated Dry ? Normal ? Heated Dry ? Normal ¦ To rapid advance one interval at a time, press the Start/Resume key. ¦ Invoking Service Diagnostics clears all status and last ran information from memory and restores defaults; It also forces the next cycle to be a sensor calibration cycle." The control board should be your last option "PROBLEM: Won’t Run or Power Up (“Dead” Keypad/Console) ¦ No operation ¦ No keypad response ¦ No LEDs or display : No power to unit or bad connection. Loose connections in dishwasher power up circuit or between keypad(s) and control. Door switch not making contact: ¦ Faulty door latch assembly. ¦ Faulty door switch Opened Bi-Metal attached to control. Multiple open or shorted circuits in keypad. Faulty control. As you can see, there are several things you need to check before you replace a control board. Good Luck and Thanks Read More... Answered by AppliancePartsPros.com | Monday, December 19, 2011
