I have a Greenstar 24i boiler which won't fire. The boiler was serviced and pronounced to be in good health. It was swithced off about a week later as the house was empty. We had a very cold (freezing) spell . Tried to fire the boiler (had now been off for about 6 weeks) Boiler would not fire but kept giving a flashing blue light. Heated outside condensation waste pipe and lagged internal part of the pipe. Tried again today (abut a week later), ambient temp outside was above freezing. Result -Rapid blue flashing light, no gurgling sound. Boiler does not fire at all. Held reset for 10 seconds, tried this a number of times. Water pressure 1.5. Power and gas supply good. Any help very much appreciated.
