5. Maintenance
Cleaning the Water Tank:
- After each use, ensure the device is unplugged and cooled down.
- Remove any remaining water from the tank to prevent stagnation and mineral buildup.
- Clean the tank with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners.
General Care:
- Wipe the exterior of the brush with a soft, damp cloth.
- Ensure the bristles are free from hair product residue.
- Store the device in a cool, dry place, away from direct sunlight and moisture.
- Do not wrap the power cord around the device, as this can damage the cord.
6. Troubleshooting
Common Issues:
- Device not turning on: Ensure the device is properly plugged into a working power outlet. Check if the power button is pressed and held for a few seconds.
- No steam being emitted: Check if the water tank is filled with water and correctly inserted. Ensure the steam function is activated (refer to operating instructions).
- Device not heating up: Verify that the power is on and the desired temperature setting is selected. Allow sufficient time (approx. 30 seconds) for the device to reach temperature.
- Hair not straightening effectively: Ensure hair is dry and detangled. Take smaller sections of hair and glide the brush slowly. Adjust the temperature setting according to your hair type.
- Steam visibility is low: The Hydro-Infusion technology disperses steam as a mist-like vapor at 0.5ml/min intermittently, so its visibility may be relatively low. This is normal operation.
