Boiler- Glowworm swift flow 75/80.
Problem appears to have started after removing radiators from wall to decorate.
With central heating turned off boiler appears to operate normal ie pilot light remains lit at all times and increases in size when turning on hot water at the taps. Sometimes however, especially if the shower has been running a noise could be heard through the radiators, as if they were filling.
WIth the CH on, the radiators all heat up as normal but after running the hot water, again especially the shower, the pilot light will be extinguished. This will occur approx 5 mins after the hot water has been turned off. The pilot can be re-lit almost immediately but will then keep going out until the CH is turned off.
The pressure gauge sits at about 0.6 bar when cold and was going to about 3 with the heating on, but is now sitting just under 2 bar.
Work carried out so far, by plumber, is to drain and refill system, bleed all radiators, replace the auto bleed ( this was seized) and replaced the pressure release valve ( this again was full of muck and continually leaking outside).
Thoughts from the plumber was that because the air bleed was seized that air was trapped in the boiler following removal of the rads by me. this in turn caused an abnormal increase in pressure with the heating on, hence the noise and knocking out the pilot. However there is no difference so I am asking you good people for any suggestions.
Regards
