Customer Question

Hi I have a Glow worm Ultracom HXI boiler. Some times it will fire up when expected, other times it won't. When I doesn't fire up if you turn the room stat down and then back up a couple of times it will eventually start. I have changed the room Stat and the programmer but this has made no difference. Can you please advise as to where I should look next.

Check the 3 port motorised valve when you do not have heating, the lever should be slack when the heating is on.
