What causes this fault?
This fault occurs when the boiler's control system detects an inconsistency in the electrical signals required to manage the burner safely. It is usually caused by a failure in the ignition components or a breakdown in the communication between the sensors and the main control board. If the boiler cannot confirm a safe flame is present, it will stop working as a safety precaution.
