I think thats a bit harsh! A fault has occurred 6 months after a PCB was changed, Its most likely unrelated and is probably one of the well documented faults with this heap of a boiler!Certainly I have, get the boy back and finish his job. Sorry if that comes across a bit rude. But exactly that and worse is the outcome if one changes parts in boiler without checking.
And regarding this problem you should not get any other advise than to use a Gas Safe Registered installer. Everything else would breach the rules of this forum and be a potential hazard to the public as it may invite people with insufficient qualifications to undertake work on boilers.
OP, the chap that repaired it last time will just be a sub contractor to Homeserve, if you have his contact details, give him a ring. Unfortunately, these boilers are moneypits and develop expensive and potentially fatal faults. I know a Plumber would say this, but I'd think about replacing it!
