6. Maintenance

6.1 Cleaning

Regular cleaning is essential for hygiene and optimal pump performance. The Comfyer W2 is designed with only 4 parts that require cleaning after each use:

• Flange
• Diaphragm
• Valve
• Milk Collector (Collection Cup)

Image: The four main components of the Comfyer W2 pump that require regular cleaning.

1. Disassemble the pump by separating the motor from the collection cup.
2. Remove the diaphragm, then split the flange from the bottle.
3. Gently hold the duckbill valve to release and remove it.
4. Wash all 4 parts with warm, soapy water.
5. Rinse thoroughly with clean water.
6. Sterilize by boiling or steaming for 5 minutes before initial use and regularly thereafter.
7. The pump motor should not be submerged in water. Wipe it clean with a damp cloth if necessary.

6.2 Storage

The magnetic charging base also serves as a convenient storage solution for your pump motor and charging cables, helping to keep your pumping area tidy.

Use the provided portable bag for easy transport and storage of your pump when on the go.

7. Troubleshooting

• Low Suction or Malfunction: Ensure all pump components (duckbill valve, flange, diaphragm, pump hub) are firmly sealed. A damaged duckbill valve can cause malfunction; consider purchasing breast pump accessories for replacement.
• App Connection Issues: Verify Bluetooth is enabled on your device and the pump is powered on. If automatic connection fails, try adding the device manually through the app's '+' button.
