Hi all, I have a Glow worm economy plus 50b bolier that is not firing up. The pilot light is continuously lit and the pump is running ok. It is controlled via an electronic ACL Drayton type timer with a wall mounted thermostat.
If I switch the heating (or hot water) to on and the thermostat is set correctly then I can hear the pump kick in but no heating (or hot water) appears. The pilot light is lit at this point but the boiler does not fire up at all.
Adjusting the thermostat or boiler water temp has no effect at all (apart from starting / stopping the pump)although whilst 'messing' with it all last night the boiler did fire up even though I hadn't really done anything. it is now back to the position of not firing up.
Any help / guidance or places to start would be gratefully received.
