Technical description: Fan failure – boiler cannot detect fan rotation – check fan operation and both connectors onto fan
What causes this fault?
This fault occurs when the boiler's control system loses communication with the fan or detects that it isn't spinning at the required speed. The most common reason is a mechanical failure of the fan motor or an electrical issue where the wires connecting the fan to the main circuit board have become loose or damaged.
