5. Maintenance and Cleaning
Proper cleaning and sanitization are essential for hygiene and product longevity.

- After each use, remove and clean all parts that come into contact with your breast and breast milk as soon as possible to prevent bacterial growth and odor.
- Rinse components in cold, clear water (approx. 20°C / 68°F).
- Wash in warm water (approx. 30°C / 86°F) using milk dishwashing soap and wipe afterwards with a clean cloth.
- The Tubing Kit should not be soaked in water for cleaning. If accidentally dropped into water, it must be completely dried before use.

5.2. Sanitization
Sanitize and disinfect all washable components before the first use and after each subsequent use.
5.3. Drying
Always ensure all parts are completely dry before assembling and storing. Wipe off any water or air-dry the parts after washing.
6. Troubleshooting
- No Suction or Low Suction: Check whether the silicone flange and other parts are assembled correctly and securely in place. Ensure there are no air leaks.
- Pain During Pumping: Using a breast pump should not cause pain. Do not try to express with an intensity setting that is too high or uncomfortable. If excessive discomfort or pain is felt, turn the pump off, remove it from your nipple immediately, and discontinue the session. Consult your healthcare professional if pain persists or if you express minimal or no milk.
- Moldy Tubing: If tubing becomes moldy, discontinue use and replace the tubing immediately.
- Leakage: Ensure all parts are correctly assembled and the double-sealed flange is properly seated. Pour milk into a storage bottle or bag as soon as possible after pumping to prevent leakage.
