Cleaning and Maintaining Your Vitamix
Routine cleaning is simple with the Self-Cleaning Program. Just add warm water and a drop of dish soap into the container, then select the Self-Cleaning Program. It completes in about 60 seconds, leaving your blender spotless.

Handling Common Problems
- Blades not spinning: Ensure the container is properly seated. Check for obstructions or debris around the blades.
- Blender makes loud noises: Verify if the blades are loose or damaged. If so, consider replacing the wet blade assembly.

Replacing the Wet Blade Assembly
If your blender is struggling with blending or producing noise, replacing the wet blade assembly can restore performance. To do this safely, unplug the unit, remove the container, and unscrew the old blade assembly following the manufacturer’s instructions.
