Technical description: Incorrect fan speed
What causes this fault?
This fault occurs when the boiler's control board detects that the fan is not spinning at the specific speed required to safely clear exhaust gases. The most common reasons are a build-up of dust and debris slowing the motor down, or an electrical failure preventing the fan from receiving the correct signals. If the fan cannot reach the right speed, the boiler will shut down as a safety precaution to prevent fumes from building up.
