BoilerFaultCodesYour boiler is performing a routine initial check of its internal air fan before it attempts to ignite the burner.
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: Fan running
What causes this fault?
This is a normal status message rather than a breakdown, occurring every time the boiler prepares to heat your water or radiators. It happens when the control board sends power to the internal fan to clear out any residual gases and ensure a safe airflow before the burner lights. If the boiler stays on this code without firing, it usually means the fan is unable to reach the required speed or the air pressure sensor isn't detecting the flow.
DIY fix possible
No action is required as this is a normal status message, not a fault code.Wait a few minutes to see if the boiler moves on to the next stage of its operation.If the code stays on screen for a long time without the boiler firing, try resetting the boiler once.
