What causes the Worcester Bosch FAIL POINT E fault?
This fault occurs when the boiler fails to sense the flow of water when you open a hot water tap. It is usually caused by a rubber diaphragm that has perished or a mechanical internal switch that has become stuck, meaning the 'demand' for hot water never reaches the boiler's control board. Without this signal, the boiler remains idle because it doesn't know it needs to start the burner.
