threw the day my glow worm 30ci runs fine right up till it turns off at bed time.but threw the night the bar presure drops below .6bar causeing the boiler not to fire up in the morning.this only seems to happen when its cold.any ideas what i should try first..........
fill your pressure back up to 1.5 bar and look for any leaks on rads, pipework etc, check the copper pipe which should gofrom boiler through the wall to outside see if that is dripping.
