I came home from work last night and the green Mains Indicator was on, the CH Demand Indicator was flashing slowly (no heat from the radiators present), and the Flame Indicator was off. I reset the boiler a couple of times and the problem appeared to go away.

This morning the green Mains Indicator was on, the CH Demand Indicator was on, but the Flame Indicator was off again but the radiators appeared to be on. Any ideas on this one please as it appears something is slowly on its way out?
