Technical description: Flow temperature sensor interruption
What causes this fault?
This fault occurs when the boiler's control board loses its electrical connection to the sensor that monitors heat leaving the unit. The most common reason is that the sensor itself has developed an internal electrical failure or the wiring connecting it to the main board has become loose or damaged. Without this vital temperature information, the boiler shuts down as a safety precaution to prevent overheating.
