BoilerFaultCodesTechnical description
Diagnostics code: Setting the burner anti-cycling time
What causes this fault?
This occurs because the boiler has reached its required temperature too quickly and needs to pause before firing up again. It happens when the heat produced by the burner cannot be carried away fast enough, often because your radiators are already warm or the system's circulation is restricted. The boiler enters this brief rest period to prevent components from wearing out due to constant stopping and starting.
This is more common during the autumn and spring when the weather is milder and your home doesn't require the boiler's full heating power.
DIY fix possible
Wait 5 to 15 minutes for the countdown to endCheck that your room thermostat is turned upEnsure radiators are not all turned off
