If there's no ultrasound but the heating is working, the issue could be with the interference filter coil or the timer. In such cases, consider replacing the component or the complete interference filter.
What to do if Elma Other has no ultrasound and no heating?
If there is no ultrasound and no heating, the issue might be a faulty printed board (BZW diode; transistors; diodes mains and HF). You can try replacing the component or the complete printed board. Alternatively, disconnect the heating cable and check the unit again with new fuses. If the short circuit doesn't occur again, the heating is faulty, and you should replace it.
What to do if Elma Other fuse is released, with no heating and no ultrasound?
