MY DAUGHTER HAS A GROUND FLOOR FLAT WITH A BAXI BERMUDA HOT WATER / CENTRAL HEATING SYSTEM . I TOOK THE RADIATORS OFF TO HAVE THE WALLS REPLASTERED . WHEN REFITTED & BLED THE BOILER FIRED UP FOR A SHORT PERIOD THEN WENT OUT , LEAVING JUST THE PILOT BURNING . IVE TRIED RE BLEEDING & TAKEN THE BUNG OUT OF THE TOP OF THE BIOLER TO BLEED THAT BUT ALTHOUGH THE BURNER FIRED UP FOR A SHORT PERIOD AGAIN IT SOON WENT OUT . COULD THIS BE AIR STILL IN THE SYSTEM . IM NO EXPERT ON HEATING BUT AM REASONABLY HANDY
sounds like air lock check in the airing cupboard there should be some bleeds in there bleed those, check pump is turning by unscrewing silver screw head on front of pump water will cum out so have a tray or towel handy, insert a small flat screwdriver if it is turning you'll feel it, if it isn't try and turn it manually on the inner screw head and try bleeding with pump on and off
