BoilerFaultCodesYour boiler is currently trying to start the ignition process to provide heating, which is a normal part of the startup sequence and not necessarily a fault unless it remains stuck on this screen.
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: Ignition sequence (heating operation)
What causes this fault?
This status occurs when the boiler begins the physical process of lighting the burner to heat your radiators. It is a natural part of the start-up cycle where the system checks components and prepares the spark to ignite the gas. If the boiler stays on this code without moving forward, it usually means the system is struggling to successfully establish or detect a flame.
DIY fix possible
Wait 5 minutes to see if the boiler proceeds to a temperature displayEnsure your room thermostat or programmer is calling for heatCheck that the boiler pressure is between 1.0 and 1.5 bar
