4. Maintenance Tips
Proper maintenance ensures the longevity and efficient operation of your humidifier and its new piezo part.
- Use Distilled Water: Always use distilled water in your humidifier. Tap water contains minerals that can accumulate on the piezo disk, leading to reduced mist output and potential damage.
- Regular Cleaning: Empty the water tank regularly and clean it with a soft brush or cloth to remove any dirt or debris. Wipe the humidifier body with a soft, damp cloth.
- Filter Replacement: If your humidifier has a replaceable filter, ensure it is changed every six months as recommended by the manufacturer.
- Proper Storage: When not in use, store the humidifier in a cool, dry place with the water tank emptied.

5. Troubleshooting
If your Dyson AM10 Humidifier is not producing mist or displays an error code, the piezo disk may be the cause.
Common Issues and Solutions:
- No Mist or Small Mist: This often indicates that the piezo disk is old, worn out, or has accumulated hard mineral deposits.
- Fault Code F1: An F1 error code on the humidifier typically signals an issue with the piezo assembly.
- Solution: The recommended solution for these issues is to replace the entire piezo service assembly. The upgraded piezo with Polymer Film is designed to address these problems effectively.
