BoilerFaultCodesTechnical description
Fault: Fuel valve actuation - The gas valve assembly cannot be actuated
What causes this fault?
This fault occurs when the boiler's main internal computer cannot properly communicate with the gas valve that lets fuel into the burner. The most common reason is an electronic failure within the gas valve itself or a fault on the printed circuit board that prevents it from sending the correct starting signal. In some cases, it can be caused by dampness or loose connections in the wiring that links these two vital components.
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.
