Technical description: Gas valve error
What causes this fault?
This fault occurs when the boiler's control board sends a signal to the gas valve to open or close, but it does not receive the expected electrical feedback. It is usually caused by a mechanical failure within the valve itself or a communication breakdown on the main circuit board. Because the boiler cannot confirm it can safely control the flow of gas, it shuts down immediately to ensure your safety.
