Troubleshooting
If you encounter issues with your Zojirushi mug, please refer to these common solutions:
- Leakage: Ensure the 'Seamless Sen' stopper is correctly installed and the lid is securely closed and locked. Check for any damage to the stopper or lid.
- Poor Temperature Retention: Verify that the lid is tightly closed. Pre-heating or pre-cooling the mug before use can improve performance. Avoid leaving the mug open for extended periods.
- Odor/Stains: Thoroughly clean all parts, especially the stopper, with warm water and mild dish soap. The fluorine coating helps prevent this, but persistent odors may require a baking soda solution soak (rinse thoroughly afterward).
- Difficulty Opening/Closing Lid: Check for any obstructions or damage to the lid mechanism. Ensure the lock button is in the unlock position before pressing the release button.
If problems persist, please contact Zojirushi customer support.
