Hi Paul

Don't know if you're still having problems but if you haven't been able to figure out any of the codes or buttons on your boiler then please contact customer support 01773 824639.

We also run a blog www.needanewboiler.co.uk where you can leave questions and comments for experts from Glow-worm.

I believe F4 on Glow Worm boiler is "Flame not detected" maybe the flame sense probe faulty, the igniter faulty or the flame detector module pcb.
With the power turned off, check the
continuity between the flame sense
electrode and terminal H2 . 4 on the
control board (PCB). Check the
connector on the end of the wire.
Check that the spark electrode is
pointing towards the flame.
Check the spark electrode. Change it.
