I have a wire come off my potterton netaheat boiler it was dislodged after it was serviced now the boiler wont fire the plumber has returned and said the boiler need replacing I would like to find where to put this wire just to see if it makes any difference and don't know where it goes. It is grey in colour and has a connector on it with a white wire with a spade on the end. The wire is coming down from the boiler towards the electronic panel but I can't see anywhere for the spade to go on the panel
It sounds like the wire from your spark generator. turn off the power remove front cover and look behind the spark generator you will see a spade end fitting
