There can be several causes. Proper cleaning is essential. Make sure all parts are clean and dry before assembling. Press all parts well before using the breast pump.

You have a standard 2-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.

Always wash all accessories of the pump after pumping or when using it for the first time, except the motor (yellow part). First rinse the breast pump and then wash it with warm water and liquid detergent. You can also put the silicone parts in the washing machine, but do this without dishes with food residues. The silicone parts can discolour.

Then dry the parts or let them air out on a clean tea towel.

You should disinfect the pump parts at least once a day. You also do this if the breast pump is brand new.

Place the silicone pump parts in a pan of water and bring the pan to a boil for about 5 minutes. Then take out the flask parts (after it has cooled down) and dry the flask parts with a clean tea towel or let it air out.

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.
