How to troubleshoot an electric breast pump

If your pump isn't expressing milk, first check that all parts are tightly fitted and that the flange size is correct for your anatomy. Start with a 'massage' or 'stimulation' mode for 5-7 minutes to trigger your let-down reflex before switching to expression mode. Keep in mind that supply can fluctuate; regular, consistent pumping sessions and ensuring the pump is positioned correctly on the nipple are key to improving flow.
