I have a NECHT WQP12-9319 dishwasher which has worked well for ages, and it has stopped working, it sounds when you close the door and the electric panel lights up, the program light does not appear and it is stuck saying 11, the pcb is clear and looks okay, could someone please advise me on how i can go about fixing it, i have looked for a service manual to help me but so far i have not been able to find one
