Re: Smeg STX1.1 dishwasher PC fault code?
Its not an error code, i guess its PO with a duff display segment ? I assume the door lock hasnt rolled over into the door closed position? Have you tried swtiching on power and hitting the programme button 4 times before the display lights up, sometimes that re sets the programme. Only other thought is the usual dispenser coil problem which efects these machines in differing ways, slave on any old valve coil if only to eliminate it. Other than that, assuming the tray underneath is not full of water, it will probably bee an new programme card.
