Hi all, my OFCH is acting up. On a refill from empty my burner does not seem to be igniting. It's not attempting to fire, not the usual switching off because it isn't bled. It's just staying on and the ignition module seems to be getting very hot but nothing else is happening.

Pics for reference

What sort of burner is in it?
An image displaying more of the boiler might be helpful.

It's bled.
There is a pic of the manufacturer plate, Can't get any more specific than that, but I'll get a pic of the whole thing too I guess.
