"In this video, we are happy to share with you the best way to maintain your Tefal pressure cooker. You should replace the gasket of your pressure cooker every year, to ensure optimum performance safely. If your pressure cooker makes no pressure, or if steam escapes from the lid, please ensure that the gasket is well placed. Do not use any object to mount the new gasket, but use your fingers to place it in the lid. "
