5. Maintenance and Cleaning
Proper cleaning and maintenance are essential for the hygiene and longevity of your breast pump. All parts that come into contact with breast milk are BPA and BPS free and are designed for easy cleaning.
Cleaning Instructions:
- After Each Use: Disassemble all parts that come into contact with breast milk. Wash immediately in warm, soapy water. Rinse thoroughly with clean water.
- Sterilization: Sterilize components regularly by boiling for 5 minutes or using a steam sterilizer. Refer to the product manual for specific sterilization guidelines for each part.
- Dishwasher Safe: Many components are dishwasher safe (top rack only). Check individual part instructions for confirmation.
- Tubing: The connection tubes should not be washed unless milk enters them. If milk enters the tubing, wash and air dry thoroughly. Ensure tubing is completely dry before reattaching to prevent mold growth.
- Pump Unit: Wipe the pump base unit with a clean, damp cloth. Do not immerse the pump unit in water.
6. Troubleshooting
- No Suction or Weak Suction:
- Check that all pump parts are correctly assembled and securely connected.
- Ensure the white valve is clean, undamaged, and properly seated. Replace if necessary.
- Verify that the tubing is not kinked, pinched, or damaged.
- Confirm the diaphragm is correctly placed and not torn.
- Pump Not Turning On:
- Ensure the pump unit is fully charged or properly connected to the AC adapter.
- Check the power outlet for functionality.
- Milk Backflow into Tubing:
- This indicates a potential issue with the diaphragm or valve. Inspect these parts for damage or incorrect assembly.
- Clean and dry tubing thoroughly if milk has entered it.
- Pain or Discomfort During Pumping:
- Ensure you are using the correct flange size. The ComfortFit flanges come in multiple sizes (25mm, 28.5mm, 30.5mm) to help achieve a comfortable fit.
- Adjust suction levels to a comfortable setting. Pumping should not be painful.
- If discomfort persists, consult a lactation consultant.
