Troubleshooting
If you encounter issues with your Larex bottle warmer, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Appliance does not turn on. | Not plugged in; power outlet malfunction; device malfunction. | Ensure the power cord is securely plugged into a working outlet. Try a different outlet. If still unresponsive, contact customer support. |
| Milk is not warming or warming too slowly. | Insufficient water in chamber; incorrect mode selected; limescale buildup. | Ensure adequate water level. Verify "Fast" or "24H" mode is selected. Descale the unit if mineral deposits are visible. |
| Milk is too hot or inconsistent temperature. | Incorrect temperature setting; milk left in warmer too long after cycle; sensor issue. | Adjust temperature setting. Remove bottle promptly after warming cycle completes. Always test milk temperature before feeding. If issue persists, contact support. |
| "Chunky" breast milk after warming. | Overheating; prolonged warming at high temperature. | Ensure temperature is set correctly (e.g., 98°F / 37°C). Avoid leaving breast milk in "Keep Warm" mode for excessively long periods, especially if the temperature fluctuates above optimal. |
| Limescale buildup in the chamber. | Hard water usage. | Descale the unit as per the "Maintenance and Cleaning" section. Use distilled or spring water for future use to minimize buildup. |
