On touch pad:
Heavy, Light,Rinse,Insta, Auto, Delay,ToughScrub,High Temp buttons all work fine.
Norm,Start/Cancel,HeatedDry,Sanitize will not light up

Door switches test ok. Cleaned ribbon connector.

Usually run washer on Normal then push Start.

Does the touch pad wear out? How can I test it to see if buttons are working?

Thanks, Mark

Yes but usually the unit wears out before the switches.
But like anything else some do just fail.

Yes see the tech sheet for the procedure.
You will need a meter.

The normal way to troubleshoot is to check the control pane (keypad), if it checks out OK then replace the control board.
Still a bit of a crap shoot but your odds are better.
