Glow-worm micron 50ff?

I would guess that the boiler has no problem lighting and that it's turning itself off as a safety measure - quite possibly because of an overheat problem - which might be caused by a pump failure- listen to the pump.

But I know nothing and can only guess - look to the manuals that Andrew discovered.

Stay calm...
