What causes this fault?
This fault occurs when the electrical supply entering the boiler drops to a level where the electronic components can no longer function safely. It is usually caused by a wider problem with the local power grid or a failing main circuit board that can no longer process the incoming voltage correctly. In some cases, loose wiring or a faulty external socket can also cause this dip in electrical pressure.
