Technical description: 10 Fan Errors in 2 hours
What causes this fault?
This fault occurs when the boiler's control board detects that the internal fan is not spinning at the correct speed to safely clear exhaust gases. The most common reason is a mechanical failure within the fan motor or a communication error between the main circuit board and the fan. Over time, wear and tear or loose electrical connections prevent the fan from starting, leading the boiler to shut down for safety.
