BoilerFaultCodesYour boiler has detected a problem with the sensor that monitors the temperature for your taps, meaning you may have inconsistent or no hot water.
This fault should be looked at by a Gas Safe engineer within the next week or two. It may get worse if left.
Technical description: Domestic hot water sensor fault
What causes this fault?
This fault occurs when the internal sensor responsible for measuring hot water temperature sends an incorrect or missing signal to the boiler's control board. The most common reason is that the sensor has physically failed due to age, or the electrical connection between the sensor and the main terminal has become loose or damaged.
