7. Troubleshooting
If you encounter issues with your LAREX B001 Bottle Warmer, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Warmer does not turn on. | No power supply. | Check if the power cord is securely plugged into the outlet and the unit. Test the outlet with another appliance. |
