Technical description: Flow temperature sensor short circuit
What causes this fault?
This fault occurs when the boiler's control board detects an electrical short circuit in the temperature sensor on the main flow pipe. The most common reason is that the internal components of the sensor have failed, or the wiring connecting it to the main board has become damaged or wet. Because the boiler can no longer safely monitor how hot the water is, it shuts down as a safety precaution.
