My dishwasher will not run. The normal light is constantly blinking. If I press the cancel button then it will not stop blinking. The quick clean light will also constantly blink. I removed the power to the dishwasher, I also tried unplugging the control panel from the control board to reset the system. Neither of these steps did anything. I think the problem may either be the control panel or the control board. I'm leaning toward the control board because it seems like the buttons respond initially on the control panel.
ANSWER Hello Nick,
Here is a way to check to see whether the control or the keypad need to be replaced:
CHECKING KEYPAD OPERATION
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 either the control or
the keypad. To determine which one, do the following test:
1. Unplug dishwasher or disconnect power.
2. Open console and disconnect the keypad ribbon connection from the
control (at P1). Put console back together.
3. Plug in dishwasher or reconnect power.
4. With door latched, disconnect and reconnect thermistor or OWI sensor
two times in less than 6 seconds.
5. Wait 10 seconds, then monitor the control’s response to the thermistor:
?If the control is OK (no longer sees shorts with the keypad
unplugged), it will respond by running service diagnostics. Listen for
it to begin filling after it concludes the 5–10 second display test at
the beginning of the service diagnostics cycle. 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 it will NOT respond to the thermistor at all and will remain off
after 10 seconds go by. Make sure the keypad is unplugged for this
test. Confirm that all other connections are made, the console and
door are reassembled, power is back on, and the door is latched;
then repeat steps 1-5 above. If still no response, replace the control
