BoilerFaultCodesYour boiler is not broken; it has simply been put into setting mode, meaning it is waiting for a command or waiting to be returned to normal 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: Programming mode (When briefly pressed, appears on the display; when flashing twice, confirms entry into programming mode)
What causes this fault?
This occurs when the 'P' or 'Mode' button has been pressed, manually placing the boiler into its programming state. It is not caused by a mechanical failure, but rather by the control board waiting for a user to adjust internal settings or confirm a change. Once the programming sequence is finished or exited, the boiler will return to its standard heating function.
DIY fix possible
