Tips for Troubleshooting Your Medela Breastpump

We know how much moms rely on their pumps to provide breastmilk and we can’t imagine the frustration a mom must feel when her pump isn’t working properly. We never want you to feel helpless if you encounter problems late at night or when you’re unable to reach out to Customer Service.

So if you’re ever in a pinch, please use these Medela troubleshooting tips to help. Here are some frequently asked questions about troubleshooting your breastpump. Please share any additional questions you have in a reply/comment at the bottom of this post.

My pump is losing suction.
If you are experiencing low suction, first check the valves and membranes:

  1. Separate the membranes from the valves
  2. Inspect the valves and membranes for damage, including cracks, chips, holes or tears.
  3. If a part is damaged, discontinue use and purchase or order a replacement.
  4. Wash the valve and membrane using warm, soapy water. Allow parts to dry completely before reassembling.
  5. Reassemble your pump, ensuring that each piece fits snugly and lies flat.

Then, check the breastshields and connectors to make sure there are no cracks. Also, make sure they attach securely.

Clean the tubing and faceplate if there is any sign of condensation and/or milk. (Faceplate instructions only apply to Pump In Style Advanced models).

  1. Begin by turning off your breastpump and removing it from the power source.
  2. Remove tubing without wiggling or pulling at an angle.
  3. Rinse tubing in cool water to remove any breastmilk residue.
  4. Wash tubing in warm soapy water, rinse in cool water and hang to dry thoroughly.
  5. Snap off the faceplate using the thumb tab and soak in warm, soapy water for 5 minutes.
  6. Clean with a soft brush or dish cloth and allow it to dry completely.
  7. Wipe diaphragm with a clean damp cloth (no soap).
  8. Then, locate the 3 connection points on the reverse side of the faceplate and reconnect the faceplate back to the pump.

Finally, inspect these connection points to ensure they’re attached securely:

  1. Tubing adapter to breastshield connector
  2. Tubing end to faceplate port
  3. Faceplate to backplate

Once you’ve completed these steps, turn on your pump and check the suction.

There’s condensation in my tubing.
If you notice moisture in your tubing, leave your tubing attached with the pump still running while you store your breastmilk after you’re finished pumping.

This will allow any condensation that has formed from the natural results of humidity to dry in the tubing.

Milk in tubing.
If milk accidentally gets in tubing, turn off the pump and remove it from the power source (Faceplate instructions only apply to Pump In Style Advanced models.)

  1. Remove tubing without wiggling or pulling at an angle.
  2. Wash tubing in warm soapy water and hang to dry thoroughly
  3. Snap off the faceplate using the thumb tab and soak in warm, soapy water for 5 minutes.
  4. Clean with a soft brush or dish cloth and allow it to dry fully
  5. Wipe diaphragm clean with a damp cloth (no soap).

  1. Hello, having issues with suction only on one side..there’s no suction and then all of a sudden there is suction. I’ve changed the membranes but have realized one does not lay flat.. Even after I just changed it..I live in Bermuda who should I call or contact?

    Many thanks!

  2. I rented a symphony pump and almost every time I use it with a pumping bra, only one breast is getting pumped. I’ve inspected all attachments and nothing seems amiss–it just won’t work on one side. Sometimes if I turn the unit on and off several times it will suddenly work. Any idea why this may be happening? It’s frustrating when I want to pump in the middle of the night and am so tired–thanks!

  3. I bought my medela freestyle pump last may. Today is gone!
    It is turning on, but not pumping at all. I am desperate!! Can´t find anything related to warranty, not to say I paid a lot of money for this product.
    It all started few days ago when pump went crazy… accelerating by itself while pumping. What I though it might be an error, ended with my device not working at all today.
    I did everything I could. Took the bat out, recharge for 24h, but nothing is happening. PLEASE HELP!!

  4. Hi. Connector piece seems to have hair line crack in yellow part.. is this why it wouldn’t suck properly i replaced that with new one. 1 week later noticed same crack in new piece. Surely this is not meant to do that. Done everything else . Suction almost non existent. 1yr old.
