Please note that I'm posting this question just to get a better idea of what the problem could be and how much I should expect to pay a professional to fix this issue for me, I do not intend to try and fix this problem myself...
I have a very strange problem with my Glowworm Ultimate boiler, in that if the boiler is cold and I switch it on, the pilot light comes on, stays on and the boiler kicks in fine. However, after around 20 minutes, the pilot light starts going out every few seconds and the boiler sparks to re-ignite the flame. It's a blue flame, I can't see any orange.
If the boiler has already been on for a while and I then turn it off for 15 minutes or so, then turn it on again, it ignites the pilot light fine and it doesn't go out, however after around 5 minutes or so, I then have the same issue with the pilot light going out every few seconds again.
It's as if the issue with the pilot light is dependant on how warm the boiler is.
Could this indicate that the thermocouple needs replacing?
Thanks for any assistance!
