BoilerFaultCodesTechnical description
Anti-cycling mode
What causes this fault?
This occurs when the boiler has reached its required temperature too quickly and pauses briefly to prevent 'short-cycling.' The most common reason is that the heat generated by the boiler cannot be moved away fast enough, often because radiators are turned off or the system is already up to temperature. By waiting a few minutes before restarting, the boiler prevents unnecessary wear and tear on its internal parts.
This is more common during the autumn and spring when the weather is milder and your home requires less heat to stay warm.
DIY fix possible
Wait for 15-30 minutes for the internal timer to finish its countdown.Check that your radiators are turned up to allow heat to escape the system.Ensure your room thermostat is set high enough to call for heat.
