3. Setup
3.1 Battery Installation
- Twist the bottom cap of the frother counter-clockwise to open the battery compartment.
- Insert 2 AA batteries, ensuring correct polarity (+/-). Batteries are not included.
- Replace the bottom cap by twisting it clockwise until secure.
3.2 Initial Cleaning
Before first use, gently wipe the frother unit with a damp cloth. The whisk can be rinsed under warm water. Ensure the battery compartment remains dry.
4. Operating Instructions
4.1 Frothing Milk
- Pour cold or warm milk into a cup or container. For best results, use milk that is not overly full, allowing space for foam.
- Submerge the whisk end of the frother into the milk, ensuring the whisk is fully covered but not touching the bottom of the cup.
- Press and hold the power button located on the side of the frother. The whisk will begin to rotate.
- Move the frother gently up and down in the milk for approximately 15-30 seconds, or until desired foam consistency is achieved.
- Release the power button to stop the frother.
- Carefully remove the frother from the frothed milk.
Tip: For optimal foam, use fresh, cold milk. Whole milk generally produces richer foam.
5. Maintenance and Cleaning
Proper cleaning ensures the longevity and hygiene of your Bialetti Milk Frother.
5.1 Cleaning Instructions
- Hand Wash Only: The frother unit is not dishwasher safe.
- After each use, immediately rinse the whisk under warm running water.
- Wipe the body of the frother with a damp cloth. Do not immerse the main unit in water.
- Ensure all parts are completely dry before storing.
- Do not use abrasive cleaners or scouring pads, as these can damage the stainless steel finish.
6. Troubleshooting
- Frother not turning on: Check if the batteries are correctly installed and have sufficient charge. Replace batteries if necessary.
- Milk not frothing effectively: Ensure the whisk is fully submerged in the milk. Try using colder milk or a different type of milk (e.g., whole milk). Ensure the whisk is clean and free of residue.
- Frother making unusual noise: Check for any obstructions around the whisk. Ensure the whisk is securely attached.
