I had the same problem. Theres a little water gauge really near by my 40FF. The water gauge was a quarter between 0 and 1. The light wont ignite if there isnt enough water in the boiler. There are two taps on either end of a flexy tube connected to the boiler. Opened them up one at a time allowing water to flow in and the gauge moved slowly to 2. I then closed both the taps back up then reset the light and its worked since.

I had this problem as do many other people. Don't call an engineer. You can DIY.

The fault was due to a loose connection- it worked if i gave it a bang!!!

I found out on the internet that the printed circuit boards are poor quality-solder drying out.In fact replacements are not the same part number.

I took it apart as per manual.( Knock off mains-just unscew front cover, swing out, pop out the plastic hinge poppers, disconnect wires carefully, pull/pop out board. )

I then inspected both sides of the board- there were 2 suspect solder joints which i made right with a soldering iron then reassebled.

Problem fixed for free in 30mins- a new board would have been £100, an engineer would have been $$$$.
