Book a Gas Safe engineer within 24–48 hours. Your boiler may be unsafe or could break down completely if left.
Technical description: Error with gas valve regulation
What causes this fault?
This fault occurs when the boiler's main control board loses the ability to send or receive signals from the gas valve. The most common reason is an internal electronic failure within the valve's solenoid or the circuit board, though loose or damaged wiring can also break this vital communication chain.
