Technical description: Problem with fan (possible wiring fault)
What causes this fault?
This fault occurs when the boiler's control system loses communication with the fan or detects that it isn't spinning at the correct speed. The most common reason is a mechanical failure within the fan motor itself, though loose or damaged wiring connections can also prevent the fan from receiving the power it needs to operate.
Engineer required
This fault requires a Gas Safe registered engineer. Do not attempt gas-related repairs yourself.
