BoilerFaultCodesYour boiler has temporarily paused because the water inside has reached a slightly higher temperature than requested, which is often a normal part of its operation.
This is a minor fault. Keep an eye on it and mention it at your next annual boiler service. Reset the boiler and see if it clears.
Technical description: Normal control stop during HTG (flow temperature > set point + 5 °C)
What causes this fault?
This occurs when your boiler generates heat faster than your radiators can dissipate it, causing the water temperature to exceed its target. It is often triggered by closing several radiator valves or by an efficient boiler reaching its desired heat level and pausing briefly to prevent overheating. This isn't usually a fault, but rather a safety measure that allows the system to cool down before restarting.
This is more common in spring and autumn when the weather is milder and your home requires less heat to stay warm.
DIY fix possible
Check that your radiator valves are fully open to allow water to flow.Ensure your room thermostat is not set lower than the current room temperature.Wait a few minutes for the boiler to automatically restart once the water cools.
