BoilerFaultCodesYour boiler is simply running through its automatic diagnostic checks after being switched on and this is not an actual fault.
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: Part of the self-test sequence sequence when switching on the appliance
What causes this fault?
This code appears because your boiler is performing a routine internal safety sweep and initializing its components. It is triggered automatically every time the power is turned on or the system is reset to ensure everything is functioning correctly before the burner ignites. Think of it as the boiler 'booting up' its computer system, similar to a laptop or tablet starting up.
DIY fix possible
Wait approximately 30 to 60 seconds for the sequence to completeCheck that the display changes to a temperature or normal operating modeIf the code persists for several minutes, try pressing the Reset button once
