What causes the Vokera E46 fault?
This fault occurs when the boiler's internal safety sensors detect that the water temperature exiting the unit has risen above safe operating limits. It is typically caused by a lack of water flow, often due to a pump failure or a blockage within the heat exchanger. In some cases, the sensor itself may have developed a fault and is providing an inaccurate reading to the boiler's control board.
