Troubleshooting
If you encounter issues with your blender, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Blender does not turn on. | Not plugged in; power outlet not working; jar not properly seated. | Ensure the power cord is securely plugged into a working outlet. Check if the glass jar is correctly placed and locked onto the motor base. |
| Ingredients are not blending smoothly. | Too little liquid; too many ingredients; ingredients are too large. | Add more liquid. Reduce the amount of ingredients. Cut larger ingredients into smaller pieces. Use the 'PULSE' function to break down larger chunks. |
| Blender stops during operation. | Overheating due to prolonged use or overloading. | Unplug the blender and allow it to cool down for at least 15-20 minutes. Reduce the load or blending time. |
| Leakage from the bottom of the jar. | Blade assembly not tightened; seal damaged or missing. | Ensure the blade assembly is securely tightened to the jar. Check the rubber seal for proper placement and any damage. Replace if necessary. |
