What causes this fault?
This fault occurs when the boiler's internal computer loses its digital connection with the sensors that monitor system pressure. It is usually caused by a loose connection in the wiring or a small electronic glitch that prevents the parts from 'talking' to each other correctly. In some cases, it can indicate that the main control board is beginning to fail and can no longer process data signals.
