Mend Glowworm 18HXI Worm Light Fault

Glow worm 18hxi?

Green light comes on & there is a temperature reading but the green light then goes off again, there is no fault (F-) showing.

I had a similar problem a couple of months ago & replaced the plastic wheel inside the control panel which turns the boiler on &off. This time that does not seem to be the problem.
Any ideas?
