There can be several causes: - cleaning well is essential. Make sure all parts are clean and dry before you assemble them. Press all parts firmly before using the breast pump and make sure they aren’t worn out; - the right size breast shield is necessary for the best results and a pain-free pumping experience. Your size can change during your breastfeeding period; - it’s important to use the right mode and level.

You have a standard 1-year warranty on the electronic parts of the breast pump. This therefore only applies to the engine. There is no warranty on the breast shield and all other silicone parts.

Note: if the motor of the pump has been damaged due to your own use, this is not covered by the warranty.

We aim to ship all orders placed on weekdays before 12:00 on the same day. There may be exceptions like busy periods and postal service closures during holidays.

First, try to reassemble the pump and check if all parts are properly dry and pressed together. If the problem is still not solved and it is still within the 1-year warranty, contact us within 5 working days at info@wowmomofficial.com

How often you need to replace the pump parts depends on how you clean them, how often you pump, and which part it is. On average, this is after 3-6 months or as soon as you notice they’re discolored from fat in breast milk or minerals from tap water. This can affect suction. Usually, the problem is quickly solved by replacing the parts.

The average user uses breast shield 24 mm. The breast pump is therefore normally supplied in size 24 together with the flanges in sizes 19 and 21. Do you want to know how to measure your nipples? click here

Do you need a size 27 or a flange in size 17? Then note this directly when ordering in the text field in your shopping cart. If you’ve already placed the order but later need a different size, send an email with your order number to: info@wowmomofficial.com

After pumping always wash all parts of the pump (except the motor). Rinse the parts first with warm water and then wash with cold water and liquid dish soap. For cleaning the silicone parts, we recommend using a soft sponge and not a cleaning brush. Then dry the parts or let them air dry on a clean tea towel. Lactation consultants recommend disinfecting the pump parts (except the motor) at least once a day until your baby is 6 months old. You should do this even if the breast pump is brand new. Place the silicone pump parts in a deep pan with water and bring the pan to a boil for about 5 minutes. Make sure the parts don’t touch the edges of the pan. Then remove the pump parts and dry them with a clean tea towel or let them air dry.

Pumping shouldn't hurt. Have you checked whether you have the correct breast shield? When in doubt, with your nipple on. Read here how to do this. We can supply the right format.

Aren't you pumping at too high a setting? Many mothers turn up the intensity, thinking they will produce more milk. This is not right. Pumping should be comfortable. It can therefore help to set the breast pump level slightly lower. Switch a position lower and you will see that it is much more pleasant.

Our breast pumps produce not more than 50 decibel.
