Hi everyone.

I have the above condensing boiler with a hot water cylinder. For the past few weeks it has been coming up with an F1 fault. the manual says ignition. It only does this now and again.

I had a local CORGI come and have a look. He said it was common on glowworms and asked if anyone had been and altered the gas. We have been here a year and not in that time. He used a gas analyser and said it was ok. He also changed an electrode (looked like a little spark plug). He did say that the fault may persist.

He was right and we are back to having some F1 faults and having to reset the boiler. Any ideas as to what else may be causing this. Don't want the boiler breaking down over xmas and i know the engineer is working away.

Thanks
Paul

Get someone to check the governor on the gas meter.Also is there a similar time zone in which it happens.

Many things can cause the F1 fault.

Low rate can drop out if incorrectly set as can high rate.
Condensate backing up to the heat exchanger
Moisture getting on the spark electrode.

or, PCB.
Id personally check all the above 1st though. Board would be a last resort

All the things i mentioned are corgi teritory im afraid, as is the door seal. The originals were rubber on early models and some perish. I found these perishing can cause F5 faults too but that another story!
