Troubleshooting

| Blender does not turn on. | Not plugged in; power outage; jar not correctly seated. | Check power connection; verify power supply; ensure jar is securely placed on the base. |
| Ingredients are not blending smoothly. | Too little liquid; ingredients too large; jar overfilled. | Add more liquid; cut ingredients into smaller pieces; reduce quantity of ingredients. Use Pulse function. |
| Loud noise or motor straining. | Overloaded; hard ingredients; improper assembly. | Reduce load; add more liquid; check blade assembly and jar seating. |
