The normal light on our Kitchenaid DW is blinking. Nothing else functions. DW will not run although if I press cancel, the pump runs for 2 minutes. Tried rebooting/resetting - nothing. Turned off power via breaker - nothing. There is some moisture in the touch panel keys as I can see it when I press a key. I'm assuming the control panel with touch pad needs to be replaced but figured I'd ask before committing.
Answer Hello Russ,
A rapidly blinking LED over one of the keys of the keypad (or sometimes a “dead” keypad/console) indicates one or more key switch lines are stuck or shorted on the control W10285178 or the keypad W10084469. To determine if the control or keypad is faulty, do the following test:
Stuck Key Test:
1. Unplug dishwasher or disconnect power.
2. Open the dishwasher door.
3. Open console and disconnect the keypad ribbon connection from the control (at P1). Make sure all other connections are made.
4. Put console back together. Do not close the dishwasher door.
5. Plug in dishwasher or reconnect power.
6. Wait 5 seconds.
7. Close dishwasher door.
8. Monitor the control’s response.
?If the control is OK (no longer sees shorts with the keypad unplugged), it will respond
by turning on the drain motor for 2 minutes. Check and/or replace the keypad if the
control responds OK.
?If the control is not OK (still sees shorts with the keypad unplugged), then the drain
motor will NOT respond. If drain motor does not start within 10 seconds, repeat or
verify that all steps were followed, then replace the control.
Since moisture has been observed in the touchpad area, the vent gasket 8269259 should be replaced to eliminate the possibility of damaging your new parts. When replacing the gasket, be sure to dry out any moisture you can reach with a clean paper towel. The vent cover is removed by turning it about 1/4 turn counterclockwise. Downward pressure has to be made to get it to turn against the seal it rests against.
