Your boiler's fan is staying on longer than it should after the heating or hot water has been turned off.
This is a minor fault. Keep an eye on it and mention it at your next annual boiler service. Reset the boiler and see if it clears.
Technical description: fan overrun
What causes this fault?
This status occurs when the boiler's fan continues to run for an extended period after the burner has finished heating your home or water. It is usually caused by the main circuit board failing to tell the fan to stop, or the fan itself sending an incorrect signal back to the control system. While it often resolves itself, it can sometimes suggest the electronic components are beginning to wear out.
