Technical description: GFA status / error
What causes this fault?
This fault occurs when the boiler's internal computer is unable to communicate with or control the ignition system that lights the gas. It is typically caused by a electronic component failure on the main circuit board or a loose wiring connection between the controller and the ignition hardware. This prevents the boiler from safely starting the combustion process, causing it to shut down for safety.
