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).

  2. I have only had my pump a month and the suction has already started giving out. None of the troubleshooting that is on here helps. It’s not the tubing or values because I have new ones. I’m really disappointed in this pump right now.

  4. I had my first pump for 6 yrs and used it at work daily for both my kids with no issues and had to supplement for my first but never used formula for my 2nd baby i had enough milk for her. I am used in 2nd pump over 9mos and starting to have issues but i still using only my pump breast mill and no formula. I am have low suction on my 2nd pump. :(

  5. Melanie, as a BF mom, I found your post very discouraging. I’ve been able to pump for seven months with plenty extra to keep on hand in the freezer. Breast pumps are machines and machines inevitably will break, you just have to get it serviced and/or replaced. To breastfeeding moms reading this – please keep at it, and don’t EVER believe the effort is wasted.

  6. Melanie – what a rough thing to say “don’t even bother”. Its an irresponsible attitude to say other moms who are trying to feed their baby the best thing for them – breastmilk. “Inevitably you are giving formula anyway” is a misinformed and to be frank STUPID thing to say. So to new and heck experienced moms outs there – YOU DO NOT HAVE TO EVER USE FORMULA if you don’t want to. And you can pump with great success. It may take some patience and a little effort but it can be done very simply. I hope no one allows this ignorant post to discourage them from breastfeeding and pumping while at work or wherever.

    As for Medla pumps – they’re wonderful. :)

    I think Medela should simply remove Melanie’s comment.
