Technical description: Fan Fault
What causes this fault?
This fault occurs when the boiler's control system loses communication with the fan or detects that it is not spinning at the required speed. The most common reasons are a mechanical failure of the fan motor itself, a loose connection in the internal wiring, or a fault on the main circuit board that prevents power from reaching the fan.
Engineer required
This fault requires a Gas Safe registered engineer. Do not attempt gas-related repairs yourself.
