Troubleshooting
If you encounter any issues with your Ninja Detect Kitchen System, refer to the following common problems and solutions:

|---|---|---|
| Appliance does not turn on. | Container not properly assembled or locked. | Ensure container is twisted clockwise until it clicks and locks securely onto the motor base. Check that the lid is also properly secured. |
| Ingredients are not blending smoothly. | Insufficient liquid or ingredients are too thick/frozen. | Add more liquid. For thick mixtures, use the PULSE function or a higher speed setting. For frozen ingredients, ensure they are not packed too tightly. The Liquid Detect feature will alert you if more liquid is needed in the single-serve cup. |
| Motor seems strained. | Overloading the container. | Reduce the amount of ingredients. Do not exceed the MAX FILL lines. Allow the motor to cool down if it overheats. |
| Lid is difficult to remove. | Lid is locked or suction has formed. | Press the release button on the pitcher/food processor lid handle. If suction, wait a few moments for pressure to equalize. |
