6. Troubleshooting

If you encounter issues with your NCVI Hands-Free Breast Pump, please refer to the following common solutions:

• No Suction or Weak Suction:
  • Ensure all parts are correctly assembled and securely connected, especially the duckbill valve and diaphragm.
  • Check for any damage or wear on the silicone parts (diaphragm, duckbill valve, flange). Replace if necessary.
  • Verify that the flange size is correct for your nipple. An incorrect size can affect suction.
  • Ensure the pump is fully charged.
• Pump Not Turning On:
  • Check if the battery is charged. Connect the pump to a power source and try again.
  • Press and hold the On/Off button for a few seconds.
• Milk Leaking:
  • Ensure the milk collector is properly sealed to the flange and the motor unit.
  • Do not overfill the milk collector beyond its maximum capacity (5oz/150ml).
  • Check the duckbill valve for proper installation and any damage.
• Uncomfortable Pumping:
  • Adjust the suction and speed levels to a comfortable setting.
  • Re-evaluate your flange size. An ill-fitting flange can cause discomfort.
