Glow-worm ultimate 40ff boiler wont fire up?

This boiler had a badly designed PCB which was replaced (at owner's expense) with a redesigned board. (The later one has green LEDs) What is important to add, however, is that the new board needs a new thermistor to make it work. I had to keep resetting my boiler which sometimes would not light at all. Now all is well.

It was dead easy to do and only cost c£11.00. I got mine from Keeptheheaton.com Order Code: 112085: Glow-worm 2000802635 Thermister.
