Got a combi boiler that's giving us grief. When the timer kicks in for the central heating, the boilers kicks off fine but not cuts out after maybe 30 seconds. At this time, we can't get any Hot water or Central Heating. If we reset the boiler and turn the CH off, the water works fine. However if we put the heating back on, it does the same again and then tries to restart after about 5 mins. Don't think it's the boiler itself as it does hot water fine when the heatings not on and it's only 3 months old. Managed to get it going three days ago by bleeding the radiators but it's just happened again.
Is this just an airlock or a leak somewhere in the Central Heating or something more sinister?
Thanks
