Check that the breast pump has been placed on the breast correctly.

Check Silicone diaphragm (refer to user manual): Are there small slits in the Silicone diaphragm? If Silicone diaphragm is damaged or broken, please order the new ones and replace the broken ones. Or you can contact the customer support center.

If the pump does not come away easily from the breast, it may be necessary to break the suction by placing a finger between the breast and massage Cushion or between the breast and pump funnel.

If the pain persists stop using the breast pump and consult your breastfeeding advisor.
