Yeah, here's the steps I'm taking:
1. Enter service mode by pressing Chime & Extra Rinse for 3 seconds
2. Press Rinse & Spin to view initial diagnostic code display - shows 0
3. Rotate Cycle Selector to view diagnostic codes, the only one that is displayed is 8E
Clear the diagnostic codes and test again, if the error returns as there is no 8E diagnostic code it will be a bad control that you installed...
Clear Diagnostic Codes
To clear the diagnostic codes list, press the Delay and
Chime keys for 3 seconds while viewing the list.
