- Pitcher, Lids, and Blade Assemblies: All removable parts are dishwasher-safe (top rack only). Alternatively, wash by hand in warm, soapy water. Use caution when handling blade assemblies as blades are sharp.
- For thorough cleaning, fill the pitcher with warm water and a drop of dish soap, then run on a LOW setting for a few seconds. Rinse thoroughly.

Storage
Store the blender upright with the pitcher assembled on the motor base or store components separately in a safe place where they will not be damaged.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Blender does not turn on. | Power cord not plugged in; pitcher/cup not properly assembled or locked. | Ensure the power cord is securely plugged into an outlet. Make sure the pitcher or single-serve cup is fully seated and locked onto the motor base. The lid must also be securely latched. |
| Ingredients are not blending smoothly. | Too many ingredients; not enough liquid; ingredients are too large. | Reduce the amount of ingredients. Add more liquid. Cut larger ingredients into smaller pieces. Use the PULSE function to break down larger chunks before continuous blending. |
| Motor stops during operation. | Overheating due to overload. | Unplug the blender and allow it to cool for at least 15 minutes. Remove some ingredients or add more liquid. Ensure the pitcher/cup is not overfilled. |
