Technical description: Boiler flow temprature sensor short circuit
What causes this fault?
This fault occurs when the boiler's internal thermometer, which monitors water temperature, suffers an electrical failure. The most common reason is that the sensor has failed internally due to age, or moisture has compromised the wiring, causing a short circuit that prevents the boiler from operating safely.
