Technical description: Gas valve error: check gas valve or wiring.
What causes this fault?
This fault occurs when the boiler's control board sends a signal to the gas valve to open, but the valve fails to operate or communicate back correctly. The most common reasons are a mechanical failure within the valve itself, a loose connection in the wiring, or a fault on the main circuit board that prevents it from sending the correct electrical signal.
