Why does Elma Other have no ultrasound but heating is OK?
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 TS540 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?
If the fuse is released, and there's no heating or ultrasound, it indicates a short circuit in the heating system. Disconnect the heating cable and check the unit again using new fuses. If the short circuit does not occur again, it confirms that the heating is faulty. Replace the faulty heating.
Why does Elma TS540 Other have no ultrasound or weak ultrasound, but heating is OK?
If there is no ultrasound or weak ultrasound, but the heating is okay, the issue could be with the output transformer, the output capacitor (6.8nF), or scorching in the transducer system. You may need to replace the component or the complete printed board, or open and check the transducer system.
What to do if Elma TS540 Other has no ultrasound but heating is OK?
If there's no ultrasound but the heating is working, possible causes include a faulty printed board (BZW diode; transistors; diodes) or a short circuit in the heating. Disconnect the heating cable and check again. You might need to replace a component, the complete printed board, or the heating element.
What to do if Elma TS540 Other has no heating but ultrasound is OK?
If there is no heating but the ultrasound is working, the issue could be a faulty heating switch. If that's the case, replace the component.
