Technical description: Fan problem – fan running too fast
What causes this fault?
This fault occurs when the boiler's internal computer detects that the fan is spinning at an uncontrollably high speed, which prevents the correct mix of air and gas. The most common reason is an electrical communication failure between the fan and the main control board, or a physical defect within the fan motor itself. Because the boiler cannot safely regulate the flame, it shuts down immediately to protect the internal components.
