What causes the Worcester Bosch 1076 W fault?
This fault occurs when the boiler's brain can no longer detect a signal from the sensor that monitors the heat of the water. The most common reason is that the sensor has physically failed or a wire has come loose, causing the boiler to shut down immediately to prevent overheating. In some cases, a fault within the main control board means it can no longer 'hear' the messages being sent by the sensor.
