Technical description: Temperature sensor fault
What causes this fault?
This fault occurs when the boiler's internal computer loses communication with one of the probes that monitors water temperature. The most common reason is that the sensor has physically failed or 'drifted' out of range, meaning it can no longer provide an accurate reading. In some cases, the issue is caused by loose electrical connections or a fault within the main control board itself.
