What causes this fault?
This occurs when the water heat inside the boiler reaches its target temperature faster than it can be circulated away to your radiators or taps. The boiler pauses its burner briefly to prevent overheating, waiting for the water temperature to drop slightly before it resumes heating. It is often caused by the thermostat being set high or the pump moving water slowly through the system.
This status is more common during the autumn and spring when your heating is on but the weather is mild, meaning your rooms reach their target temperature quickly.
DIY fix possible
Check that your radiator valves are open to allow heat to escape the boilerEnsure your room thermostat is set high enough to call for heatWait up to 5 minutes for the code to clear automatically as temperatures drop
