Technical description

Fan or fan wiring error

What causes this fault?

This fault occurs when the boiler's control system detects that the fan is not spinning fast enough to safely remove exhaust fumes. The most common reasons are a mechanical failure within the fan motor itself, loose electrical connections, or a fault on the main circuit board that prevents power from reaching the fan.

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.
