5. Operating Instructions
Once installed, the frother whisk is ready for use. Place your desired amount of milk (hot or cold) in a cup or frothing pitcher. Position the cup under the frothing arm so the whisk is submerged in the milk. Activate the frothing function on your Ninja coffee maker. For increased milk foam volume, position the frother at a slight angle on the milk's surface.

6. Cleaning and Maintenance
To ensure longevity and hygiene, clean the frother whisk after each use. The whisk is designed for easy cleaning and is safe for both hand washing and dishwasher use. Its smooth surface prevents residue buildup, making it simple to rinse clean.
- Hand Washing: Detach the whisk from the frothing arm. Rinse under warm water and use a mild dish soap if necessary. Ensure all milk residue is removed.
- Dishwasher: The whisk is dishwasher safe. Place it on the top rack of your dishwasher.
7. Troubleshooting
If you encounter issues with your frother whisk, consider the following:
- Whisk not spinning: Ensure the whisk is correctly installed and securely attached to the frothing arm. Check for any obstructions.
- Insufficient froth: Verify that you are using fresh milk. Cold milk generally froths better than warm milk for cold foam. For hot froth, ensure the milk is adequately heated before frothing.
- Difficulty cleaning: Clean the whisk immediately after use to prevent milk residue from drying and hardening.
