I have an Ideal C95FF combi-boiler which was working fine although not all of the radiators heated up to the maximum. Bled a couple of them which went fine. But now my boiler is cylcing on/off every 10seconds or so. It doesnt matter if the control switch is on/off/timed does it automatically. How do I stop this?

Mine is doing exactly the same!
Did you ever sort this out? If so what was wrong?
