BoilerFaultCodesTechnical description
Gas valve error
What causes this fault?
This fault occurs when the boiler's internal computer is unable to communicate with or control the movements of the gas valve. The most common reason is an electrical failure within the valve’s motor or a faulty ignition lead that prevents the unit from sustaining a flame safely. In some cases, the main circuit board may be sending incorrect signals, leading the boiler to shut down as a safety precaution.
Engineer required
This is a high severity fault. Stop using the boiler and call a Gas Safe registered engineer. Do not attempt gas-related repairs yourself.
