Manufacturer manualHeating remaining cut off for XX amount of time
What causes this fault?
This code appears when the boiler reaches its target temperature and briefly pauses to prevent the system from overheating or wasting energy. It is often caused by the heat not leaving the boiler quickly enough, which can happen if your radiators are turned off or if there is a minor restriction in the pipes. In many cases, it is simply a sign that the boiler is waiting for the system water to cool down slightly before firing up again.
This is more common in spring and autumn when the weather is milder and your home requires less heat to stay warm, causing the boiler to cycle more frequently.
DIY fix possible
Check that your room thermostat is set to the desired temperatureOpen all radiator valves fully to ensure heat can move away from the boilerWait up to 20 minutes for the 'anti-cycling' timer to finish and the boiler to restart automatically
