Glow worm Micron Locking out

[tonybramley]

I have a Glow Worm Micron 80FF boiler. It started turning itself off and showing the reset light. This started happening occaisionally and now happens every day. I can re-light by resetting the boiler but does anyone know the cause. Many thanks in advance.

My problem was solved by changing the pipework. The boiler had been installed on a system that was piped up for a floor standing boiler. Once the overflow pipe had been swapped round it worked fine...til today!
