Is your Medela Pump losing suction? If you’re experiencing issues with your Medela breast pump losing suction, there are several possible reasons and solutions you can try:

Check the Assembly
Make sure all the components of your Medela breast pump are properly assembled. This includes checking that the breast shield, valve, and membrane are correctly fitted and securely attached. Any loose or improperly fitted components can result in a loss of suction.
Clean the Pump
Regularly cleaning your breast pump is essential for maintaining optimal suction. Take apart the pump and thoroughly clean all the parts that come into contact with milk, including the breast shield, valve, membrane, tubing, and collection bottles. Use warm soapy water or follow the manufacturer’s instructions for cleaning. Rinse thoroughly and allow the parts to air dry before reassembling.
Check the Tubing
Always, inspect the tubing for any kinks, bends, or damage that may be affecting the suction. Straighten out any kinks or bends, and replace any damaged tubing if necessary.
Check the Breast Shields and Connectors
Do ensure that the breast shields and connectors are properly connected and securely attached. Make sure they are free from any cracks, tears, or damage that may affect suction.
Inspect the Valves and Membranes
The valves and membranes play a crucial role in maintaining suction. Check the valves for any dirt, debris, or wear. If they appear dirty or worn out, clean or replace them accordingly. The little white flaps can tear or the yellow connectors can crack. If either of these things happens, your breast pump will lose suction. This happened to me and the pump actually made a different sound compared to normal.

Replace Worn-Out Parts
Over time, the valves and membranes of your Medela breast pump may wear out and lose their effectiveness, resulting in decreased suction. Replace these parts (aff link) regularly as recommended by the manufacturer or if you notice any signs of wear and tear.
Check the Power Source
If you’re using an electric breast pump, make sure it’s properly plugged in and receiving adequate power. Low battery or insufficient power supply can result in reduced suction.
Check for Air Leaks
Also, check for any air leaks in the system can compromise suction. Check that all connections, including the tubing and collection bottles, are securely attached without any gaps or leaks.
Try Different Suction Levels
Medela breast pumps often have adjustable suction levels. Experiment with different suction settings to find the one that works best for you and ensures optimal suction.
Contact Customer Support
