johnnyknox Posted September 14, 2007 Share Posted September 14, 2007 Mines bust.....again! It's been playing up for years but now I think it's had it.. When we do finally get the pilot light lit, it starts banging and then the flame blows out again Anyone know if there is anything I can do?

Chris and Alana Posted September 15, 2007 Share Posted September 15, 2007 Are you saying it starts banging when just the pilot light is on? Or when It is on full flame and then it all cut's off? What boiler do you have? Link to comment Share on other sites More sharing options...
Supragal Posted September 15, 2007 Share Posted September 15, 2007 If you've had it for years it's not worth messing about with. You don't want it blowing up in your face! Banging could mean air in the system but it wouldn't be blowing the pilot out. Link to comment Share on other sites More sharing options...
Havard Posted September 15, 2007 Share Posted September 15, 2007 The banging could be excess gas igniting! I would get professional help or get it replaced but the new condensing boilers are not cheap! My bet it the thermocouple!! Cheap to replace too!! Or it could be completely fucked!! H.

What boiler do you have? Yeh, when on full flame it starts banging and then blows the flame out completely I have got someone coming to look at it next week, so I am not going to muck about with it anymore. Thanks for your responses, just wasn't sure if it might be something really simple that I was missing. It's a Glow Worm Fuel Save Mk II .... btw Link to comment Share on other sites More sharing options...
RIJ8631 Posted September 16, 2007 Share Posted September 16, 2007 could possibly be that the pump is stuck - firing up, but because the pump is not circulating , it then goes into an overheat situation, and the pilot cuts out as a safety precaution. Although i'm a boiler engineer, i am not familiar with the glow worm range. You could always check to see if the pump is circulating. Normally if the fan is not turning the boiler should not fireup. cheers Ian Link to comment Share on other sites More sharing options...

The banging seems to be coming from the water pipe that comes out of the top of the boiler and it sounds like the pump is just not working properly. Thanks agian mate...will get the pump looked at too Ta Stef Link to comment Share on other sites More sharing options...

He is one of those blokes that never throws aything away and had a spare pump lying around that was exactly the same as the one we already had installed. Swapped them over and bish bash bosh...I am no longer freezing! Thanks Stef Link to comment Share on other sites More sharing options...
