What causes the Vokera E02 fault?
This fault occurs when the boiler's control system tries to start the burner but cannot detect a flame after several attempts. The most common reason is a lack of gas reaching the burner or a failure in the ignition system that prevents the spark from creating a steady fire. It can also be caused by worn-out sensors that fail to tell the boiler that a flame is actually present.
