Hi, I have a 6yr old Halstead Ace High combi boiler which has never given me any problems until now. About 3 - 4 weeks ago the heating stopped working (only noticed when i tried to click the heating on a chilly night).

It didn't work and I noticed that the water pressure had dropped to about 0.2 bar. I've tried re-pressurising it back up to about 1.5 bar, but nothing.

However, the hot water continued to work, until a few days ago. Now the hot water isn't working either. The burners fail to light and the only illuminated LED on the front of the unit is the green power on indicator. Not even the red ignition lockout LED is on.

Can anyone out there make a suggestion? Please?!

it will have overheated due to there being no water in the system. there is a overheat thermostat that need to be maually reset. Bottom left underside of the boiler.

when you turn the filling loop on does it let water in the the central heating system?
