Technical description: Fan jammed or faulty winding, fan connections, or PCB failure.
What causes this fault?
This fault occurs when the boiler's control system can no longer detect the fan spinning at the correct speed to safely remove exhaust fumes. The most common reasons are either the fan motor itself burning out over time or a build-up of dirt and debris physically jamming the internal blades.
