hi my greenstar 30cdi stopped working - no hotwater or heating. Green burner light off, all other lights off except for the blue diagnostic light which is on and not flashing. Tried turning on and off. tried pressing re-set (all lights come on for a few seconds then go off). still ot working - any help appreciated.

I realise that this is an old post now but I have an almost identical problem developed with my boiler - however I am getting hot water, just no central heating. Only light that is on is the blue light, it is not flashing.
Any help with this would be greatly appreciated.
