5. Maintenance

5.1 Cleaning

Regular cleaning is essential for optimal performance and longevity. The 2500 ML water tank is designed for easy cleaning. Simply empty any remaining water, wipe down the interior with a soft cloth, and allow it to air dry. For thorough cleaning, especially if mineral buildup occurs, use a mild detergent or a vinegar solution. Ensure the unit is unplugged before cleaning.

5.2 Water Quality

Using filtered or distilled water can help prevent mineral buildup and extend the life of your diffuser, especially in areas with hard water.

6. Troubleshooting

• No Mist Output: Check if the water tank is filled above the minimum level. Ensure the unit is properly plugged in and powered on. Clean the ultrasonic plate if there is mineral buildup.
• Lights Not Working: Verify the unit is powered on and the light function is activated. If only certain colors are not working, contact support.
• Unit Shuts Off Unexpectedly: This is likely due to the automatic safety shut-off feature when the water level is too low. Refill the tank.
• Unusual Odor: Clean the water tank and replace the water. Ensure only pure essential oils are used.
