The “High Temperature” light is flashing. Cannot get any of the other buttons to work. Start button does not work either. The only other button that lights up is the Normal Cycle button, but it will not stay lite up. Can you help?
Could not find info on a XTP11, the following tech sheet is for a XTPQ1.
Hopefully they are the same

A flashing key is often a stuck key.
Remove the ribbon cable from the control pad and check that the key opens and closes with a meter.
If it does not open then the keypad must be replaced.
