Your right to loose confidence in him .the only reason to replace or blow up the pressure balloon( pressure vessel) is if the boiler is over pressurising and dumping water out of the safety valve . these can be replaced if faulty , which I doubt it is .
Just because someone is gas safe doesn't mean they have any boiler fault experience
Hi what colour light flashes slowly? When this happens
He did say it is releasing water outside - the boiler is in a fitted kitchen and he said he would have to take cabinet out to fix it and if we needed new boiler it wouldnt fit in cupboard. The main restart light flashes but slowly.
Ok , you could replace like for like , but can you tell me if its the blue or the red light that flashes slowly, thanks
Hi - its the red.
Hi , when the red flashes slowly , is the blue light on or flashing?
Just the red light - I have never seen a blue light - not sure it has one.
Ok . can you give me a few minutes whilst I look up the manual , thanks
Hi . you have a PCB faulty . you need to change the PCB in the boiler .
Its quite an expensive part , unfortunately . how old is the boiler?
Hi, not sure - it was in the house when we moved in - but its fairly old in boiler terms I think. I have phoned another plumber for a second opinion - he's hopefully coming out next week.
