Chaffetaeux Celtic 2,20 FF. Recently cleaned heating return filter as combi was tripping out on OverTemp.(It was blocked)
I refilled the system as per manual and recharged, heating appears to work fine, but on hot water, mega noise and bangs from the boiler, the pressure goes up and the pressure refief valve blows and the pilot light goes out. Any one help ?
