I have no hot water or heating.
I've checked the pressure gauge and set it to 1.5.
I've switched it off at the mains and left it for a short while before switchinbg it on and trying to reset it.
It sounds like it's kicking in and the burner indicator comes on, but after a short while goes back off again.
How do i solve this?

Flame rectification sounds to be failing, check the condense waste pipe is clear, especially the inital trap which tends to block with sand from the main heat exchanger (the sand is residue from when the heat exchanger was cast).
