5. Operating Instructions
5.1 Pumping Process
- Turn on the pump and adjust the suction and speed settings to your comfort level. It is recommended to start with a lower suction and gradually increase as comfortable.
- As the pump creates a vacuum, it will stimulate milk release. Milk should flow through the breast pump into the attached bottle.
- Once you have achieved 2 or 3 let-downs, you may switch to the other breast and repeat the process, or continue pumping both simultaneously if using two pumps.
- Pump for approximately 30 minutes from both breasts combined, or as advised by a lactation consultant.
- When finished, turn off the pump and carefully disassemble it.
5.2 Discreet Use
The Elvie Pump's compact design allows it to be worn inside a standard nursing bra, providing discretion during use.

6. Cleaning and Maintenance
Proper cleaning and maintenance are essential for hygiene and the longevity of your Elvie Pump.
- After each pumping session, disassemble the pump according to the manufacturer's instructions.
- Rinse all breast pump parts that came into contact with milk (e.g., breast shield, spout, valve, bottle) with cold water immediately.
- Wash these parts with hot, soapy water.
- Rinse again thoroughly with clean water.
- Allow the parts to air dry completely on a clean surface or pat them dry with a clean towel.
- It is recommended to sterilize your pump parts daily, either by boiling or using a steam sterilizer. Refer to your pump's specific instructions for recommended sterilization methods.
The Elvie Pump components are made from silicone, which is durable and easy to clean.

7. Troubleshooting
If you encounter issues with your Elvie Pump, consider the following common troubleshooting steps:
- Low Milk Output: Ensure the breast shield is correctly sized and positioned for a proper seal. Check that all pump parts are assembled securely and that suction settings are appropriate for your comfort.
- App Connectivity Issues: Verify that Bluetooth is enabled on your smartphone and that the Elvie app is updated to the latest version. Ensure the pump hubs are charged.
- Milk Leakage/Spillage: Confirm that all components are correctly assembled and sealed. Ensure your bra provides adequate support to hold the pump firmly against your breast, maintaining a consistent seal. Avoid leaning forward excessively during pumping.
- Pump Not Turning On/Charging: Check that the USB charging cable is properly connected to both the pump hub and a power source. Allow sufficient time for charging.
For persistent issues, refer to the official Elvie support resources or contact customer service.
