Your boiler is taking a short, normal break after finishing a heating cycle to prevent overheating and ensure everything cools down properly.

What causes this fault?

This occurs when the boiler has successfully met the temperature requested by your thermostat and shuts the burner off to prevent the system from getting too hot. It is a built-in safety delay that allows the internal components to cool down and the water to circulate before the boiler is allowed to fire up again. This 'anti-cycling' period is a normal function designed to protect the heat exchanger and improve energy efficiency.
