Technical description: The boiler keeps resetting
What causes this fault?
This fault occurs when the boiler's internal computer system loses its place or experiences a communication break, forcing it to constantly reboot to try and clear the error. It is typically caused by a failing electronic control board or a loose connection in the wiring that prevents the main components from talking to each other properly.
