To troubleshoot your breast pump, we suggest that you first check the pump motor. Here’s how you can do it:
- Remove the pump motor and cover the suction hole with your thumb to check the suction of the motor. Try level one and level nine to feel the suction difference.
- If you have two pumps, switch the motors with the collection cups to identify if there is an issue with the motor.
If the motor is working well, you can then check the pump accessories and other possible issues.
Check the following:
- Ensure that the silicone diaphragm and valve are not damaged and are installed correctly. Follow the instructional videos or manuals to install the breast pump accessories properly. You can verify if the 1 / 5 seal is installed correctly by checking whether the valve/linker/diaphragm moves.

- Since the size of a mother’s nipples changes at different stages, measure the size of your nipples and choose the appropriate flange size according to the size chart.
- A suitable bra and correct sitting posture can ensure that the breast pump works properly. The bra should be full coverage, made of elastic fabric, have a flip-top, and steel-free pads. Make sure the flange is pressed firmly against your breast in pumping mode and tighten your bra to ensure a snug fit.
