Hi,

I've had a few problems with my boiler red light (of death!) on me since september, but now seems to trouble keeping alight when pressure is any less than 2.5bar. It can sometimes cut out immediately others it will attempt to light.

Its even sounded as if its had trouble catching alight. Everytime i've called out british gas to look at it the thing decides to work again (for about another 2 weeks)

Any ideas would be appreciated!

Your system needs re-pressurised! When the heating is running the water expands and the pressure rises. The pressure vessel should be checked in case the diaphragm has perished. Also check for a leak on the system.
