Breast pumps are essential tools for breastfeeding mothers, but even high-rated brands like Medela can encounter issues during usage.
Although Medela is highly regarded, improper use can lead to problems such as weak suction and milk splattering. Let's explore the causes and solutions for these issues with Mytour.
1. Weakness in Medela Swing and Pump Breast Pumps
If one day your breast pump seems weaker without any apparent reason, check the white valve at the suction bottle's tip.
– The white valve is a crucial part for generating suction force, but it's delicately designed. Even a tiny tear during usage can significantly reduce suction force. Therefore, handle the white valve with gentle cleaning, avoiding frequent boiling.
– Motor Mask Being Activated. This can happen accidentally or intentionally when you cover the air tube or motor face with your hand: position the motor facing upwards, press all five fingers firmly around the raised spherical area in the middle of the motor. You may press firmly around each point surrounding the spherical area to ensure it fits snugly into the motor body as initially.
– Additionally, check if the battery is still good; weak batteries can also result in a weak adapter.

2. Uneven Suction Strength on Medela Double Pump
For the Medela double pump, you might encounter an issue with uneven suction strength on each side. To resolve this issue, check:
- White valve for any tears or proper installation. A damaged valve can weaken the suction of the Medela pump.
- Yellow valve: similar to the white valve, replace if damaged or misaligned.
- Inspect all accessories of the Medela breast pump.
3. Loud Noise Issue in Medela Breast Pump
Many pumps exhibit a loud motor noise when suction is weak, causing discomfort for mothers, especially during a baby's nap or pumping at the workplace, affecting others. It may even disturb the baby's sleep. Therefore, check if the pump has any malfunctions and if all accessories are properly assembled.

This situation is common in pumps like the Pump model, but there's no need to worry as it doesn't significantly affect the pumping process.
4. Medela Breast Pump Splashing Milk
Milk splashing is often observed in the Medela Swing model when milk reaches the pump funnel. In this case, press the pump mode immediately to prevent milk from running into the motor, potentially damaging the pump. If the pump splashes milk, turn it off immediately without attempting to continue pumping.
If, unfortunately, milk or water has entered the motor, turn off the machine and promptly take it to the warranty center for timely resolution. Learn more about troubleshooting and cleaning the Medela Swing breast pump when experiencing milk splashing.
Don't worry too much; the manufacturer's upgrades, such as Medela Swing, Freestyle, have addressed this issue, eliminating milk splashing concerns seen in earlier models.
5. Medela Pump Not Running, Not Suctioning
If the pump is completely inactive and not suctioning, check if it's plugged into the power outlet or if the connection is loose. Also, verify if all components are correctly assembled, including air tubes and valves. If the power supply is normal and there are no issues, your pump's motor may be faulty. Take it to the warranty center for advice and assistance.

To avoid encountering these issues, mothers must know how to clean and use breast pumps correctly. Proper maintenance ensures durability, aesthetics, and fewer incidents. For more information, refer to the article: Proper Breast Pump Cleaning Tips for your convenience.
Note: When purchasing a breast pump, choose reputable sellers to avoid unclear origins or used machines. Carefully inspect second-hand pumps. Buying from Mytour, with a 12-month warranty, ensures your peace of mind.
