My Boiler will switch on and off during CH mode with a cycle of about 30 seconds off followed by 10-15 seconds on this after a continuous cycle to reach temperature. The manual states that the Control Board is fitted with an anti-cycling device which should prevent the boiler re-starting for 2 1/2 minutes once temperature has been reached. This is clearly not working. I have been told to change the thermistors but I have checked these and they seem ok i.e around 2.5k when switching the boiler off.
Is this problem caused by a faulty PCB or any other components. I have seen this raised elsewhere in this forum but without any helpful response.
Thanks Pete20
