Hi,
Can someone tell me if I need to get someone who knows viessmann boiler.
Boiler not firing, Engineer says the PCB not firing because of FF error. He got a replacement PCB, tried to fit it today.
Engineer says he can get into service mode, but not set the PCB to match the boiler model. It kept flashing at 1 and it needs to be 8. He kept turning the left dial saying the number should move.
Now he says the part is faulty and that it needs to be returned. I can't believe that a new part would be faulty. He's already changed something that looks like a spark plug, and I'm wondering if I'm being taken for a ride and he's just guessing what's wrong.
