Unplug dishwasher or disconnect power. Open the dishwasher door. Open console and disconnect the keypad ribbon connection from the control (at P1). Make sure all other connections are made. Put console back together. Do not close the dishwasher door. Plug in dishwasher or reconnect power. Wait 5 seconds. Close dishwasher door.
Monitor the control’s response:
If the control is OK, it will respond by turning on a Drain Motor for 2 minutes. Replace the keypad if the control responds OK.
If the control is not OK, then the drain motor will NOT respond and will remain off. If no response, replace the control.
