hi
i have regular conventional boiler Halstead hero 40 fitted 3 years ago it began to turn off on its own about 4 weeks ago, so as the 6 radiators are old i put in salamandar sludge remover 3 weeks ago, in this time the boiler has been going off from time to time, but yesterday it completely gave up the ghost and wont fire up at all, today there is a dim light at times as if it is trying to start any advise or information would be appreciated
cheers
