Can you help me to find out what is wrong with my boiler it fires up then a few seconds later it shuts back down again? I have recently had the gas valve changed but still the problem remains please help me.

just done mine for second time, first time it appeared to be air pressue, adjusted and worked ok for 2yrs. then happened again, changed air pressure switch this time but still didnt work. traced fault to partial blockage to flue. check flue restrictor is correct IF NEEDED then check rubber seal in flue hasnt moved this is not a gas valve fault

This sounds like what is happening with my boiler. It seems to fire up but actually doesn't no warning lights or anything. I have had a repairman out three times:

- first time replaced the venturi and worked fine

- second time he emptied water that had collected from the flue and suggested the flue wasn't angled correctly

- third time had a guy out to measure the downfall of the flue and it is correct, and the guy just blew in a tube to get the boiler to work again

Well it's now broken down for a 4th time and I would really appreciate some help as to what it might be. The apartment is brand new, 5 months old and the first problem occurred after 4 months, then it has broken down ever since. Thanks

get the guy back who changed the gas valve he must of made an incorrect diagnosis of the problem, was he corgi reg for boilers?the cause could be many things from the gas meter regulator to a whole number of things inside the boiler but is very unlikely to have been related to the gas valve itself
