BoilerFaultCodesTechnical description
Fan running (heating operation)
What causes this fault?
This status occurs when the boiler begins its ignition sequence and initiates the fan to clear out the combustion chamber. It is a normal part of the start-up process and indicates that the control board is successfully communicating with the fan motor. If the display stays on this code for a long time, it may suggest the fan is struggling to reach the speed required to proceed to the next step.
DIY fix possible
Check if the room thermostat is turned up to signal for heatWait up to 2 minutes for the boiler to complete its pre-ignition safety checksEnsure there is power to the boiler and the display is active
