Hi
Been having a few problems with this boiler would like ideas as to what the fault could be.
Its 4 years old, been no problems, then on comes the "B" error light constant and not flashing, a look in the book says try reset etc which i did but no luck, turned off and on many times but as soon as you either switched on or ran the hot tap the B light would come on again. So I decided to call British Gas for a free estimate, had to wait 4 days tried it every day and faulty, typical the guy comes and it works ! he turned it off and on a few times it worked ok. He said it could be the mainboard or coil/spark i think he said. Anyway the past few days its been problems, it has worked at times but to get it work we have to switch it off and on a few times first, as you either switched on or ran the hot tap the B light would come on again but intermitant.
At one point yesterday i turned the tap on and it seemed like it was struggeling to do something then after about 1min the D light came on and the hot water worked. Today the heating came on for a hour and then went off on its own, back to B error. Is it likely to be the mainboard or something else, and what apx cost for parts would you suggest.
Thanks.
