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 controlís response:
a) If the control is OK (no longer sees shorts with the keypad unplugged), it will respond by turning on a Drain Motor for 2 minutes. Replace the keypad if the control responds OK.
b) If the control is not OK (still sees shorts with the keypad unplugged), then the drain motor will NOT respond and will remain off. If no response, replace the control.

I followed these instructions and got the the control board. The blinking light continued. So now I'm stuck with a $95 controler and still need to spend another $125 for the control panel. What a waste of money!
