Worcester Bosch C6: Fan speed fault (C6 / 215)
May need an engineerWhat it means
The fan is not running at the expected speed. Fan, flue blockage or wiring.
Safe things to try first
- Check the flue terminal outside is not blocked by leaves, nests or snow.
When to call an engineer
Fan replacement is a Gas Safe job because the flue must be checked afterwards.
Never remove the boiler cover or work on gas components yourself. It is illegal unless you are Gas Safe registered, and it will void your warranty.
