Follow these steps to assemble your KOIOS Personal Smoothie Blender:

8. 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; cup not properly engaged; power outage. | Ensure the power cord is securely plugged into a working outlet. Press the blending cup down firmly onto the motor base until it engages. Check your power supply. |
| Ingredients are not blending smoothly. | Too little liquid; too many ingredients; ingredients are too large or hard. | Add more liquid (at least half the volume of solid ingredients). Reduce the amount of ingredients. Cut hard ingredients into smaller pieces. Use pulse action for tough ingredients. |
| Leakage from the cup. | Blade assembly not tightened; cup overfilled. | Ensure the blade assembly is securely screwed onto the cup. Do not fill ingredients past the MAX line on the cup. |
| Burning smell from motor. | Overheating due to prolonged use or overloading. | Immediately stop operation and unplug the blender. Allow the motor to cool down for at least 15-20 minutes. Reduce load and blend in shorter intervals. |
If the problem persists after trying these solutions, please contact customer support.
