Woke up to a cold house this morning. Red lock out light on control panel and on burner. Suspected frozen water in oil filter/line (minus 5 degrees and 4 inches of snow here) so poured boiling water over the filter housing and pipes and gave it a moment to warm up. Pressed the reset button on the burner. Burner fired but was running rough then cut out. Tried resetting again and it fired but cut out after a few seconds. Now it won't fire at all. I can hear the pump run for a few seconds then it locks out straight away. Suspect oil not getting through.
It's an old Boulter Camray 5. The oil tank is about 60ft from the boiler. The oil pipe runs outside mostly above ground. Two filters, one at the tank outlet, one where the pipe goes through the wall to the boiler. I've had big issues with getting air locks out before when the tank ran dry (three hours before the oil delivery arrived!) and the symptoms were exactly as today but that was two years ago and it has been faultless since. Can't think why there would suddenly be air in it now.
Any suggestions for what to try next? I know how to bleed air out of the burner, it's just a horrendously messy job and stinks the house out so don't want to do it unless really necessary.
