7. 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; pitcher/cup not assembled correctly; thermal cutout activated. | Ensure unit is plugged in. Verify pitcher/cup and lid are securely locked. Unplug, wait 15 minutes for motor to cool, then plug in again. |
| Ingredients not blending smoothly. | Too many ingredients; not enough liquid; ingredients too large. | Reduce ingredient quantity. Add more liquid. Cut large ingredients into smaller pieces. Use PULSE function to break down larger chunks. |
| Lid/cup leaks during blending. | Lid/blade assembly not properly sealed. | Ensure lid is pressed down and handle is locked. For Nutri Ninja cups, ensure blade assembly is screwed on tightly. |
| Burning smell from motor. | Overloading the motor. | Reduce load. Unplug and let the motor cool down for 15 minutes. This is often a temporary issue with new motors. |
