6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Food does not stay hot/cold. | Lid not sealed properly; no pre-heating/pre-cooling; extreme ambient temperature. | Ensure lids are tightly sealed. Pre-heat/pre-cool the jar before use. Use the insulated pouch. |
| Lids are difficult to open. | Vacuum pressure buildup (especially with hot contents); food residue. | Allow contents to cool slightly before opening. Clean lids thoroughly. |
| Unpleasant odor inside jar/container. | Improper cleaning; food residue left for too long. | Wash immediately after use. Use a mixture of baking soda and water to soak, then rinse thoroughly. Ensure complete drying. |
