It can be unsettling when your pump starts changing settings on its own.
A quick check
- Look closely at your pump motor especially around the seams and the suction hole, for any yellowish, milky residue or water marks.
- If the motor still turns on, check if the air coming from the suction hole has a sour milk smell.
- It is also critical that the milk collector, diaphragm, valve, and flange are completely dry before assembly
If you notice any of these signs, please stop using the pump and contact our customer support team for assistance.
Helpful tips for prevention
- Clean all pump parts after each use, but never wash the pump motor itself.
- Try to pump in an upright position to help prevent milk backflow.
- When you are finished, always turn off the pump and remove the pump motor before pouring your milk.
- Use a storage bag when traveling to protect the pump from bumps or falls.
