Bob for Model Number Whirlpool GU2500XTPTBT The 'glass xpress' LED is flashing fast. I did the diagnostic test. I think it is the main circuit board is bad. If I turn off the breaker and turn it back on after an hour, it doesn't blink initially but then resumes blinking. I have had many electronic issues with this thing in the past including several TCO's. Can you confirm what my issue is this time? Is it worth repairing? The machine was installed in late 2005, but is used less than 5 months per year by two people.
Answer Bob, You're probably on target with your guess, the touchpad WP3385744 is the more likely issue, " PROBLEM: WON’T RUN AND LED ABOVE KEY(S) IS FLASHING RAPIDLY - Short circuit(s) in keypad or in control’s input lines that read the keys. - Don’t replace both: See first section of “Checking Keypad Operation” for test to determine whether shorts are in the keypad or the control.". Once you've installed the control panel, you will want to conduct the "service diagnostics cycle program" to reset the eeprom memory. As for the TCO issues, you may want to check and insure the electrical connections in the junction box on the front frame of the dishwasher are correct and tight, Loose connections and wiring, and voltage issues can cause the thermal fuse to fail.
