Technical description: Possible issue with fan voltage
What causes this fault?
This fault occurs when the boiler's main control board detects an incorrect voltage being sent to the fan motor. The most common reason is that the fan components have worn out and are drawing too much power, or the control board itself has developed a fault and can no longer regulate the electricity properly.
