thanks, definately a compact E, I got as far as the air pressure switch which was not responding as it should in the flow chart, but I am not sure where to go from there, sorry Im only a mere sparks , stuck on a sunday afternoon with no hot water!
I have a 5 year old gloworm compact 80, when the power switch is on, the pump runs contiuously, even with hot water demand only, when it is called for demand i get no ignition & then it locks out, boiler has been fine until now.
