When on central heating, boiler comes on but then goes off for a few seconds and then starts up apain. Runs for a while and then repeats this. Changed overheat stat, but no joy?
got a copy of guide, tried to sort it from this but nothing we try seems to fix it, i've seen lots of people have had same problem but can't see any solutions
