Our capsules are made from high quality stainless steel - these can expand a little during use. Whilst this won't cause damage to your machine, they may require a little nudge to drop from the brewing chamber into the drip tray.
As a general rule, a little jiggle with your index finger should usually help to release the capsule. If required, you can also use the WayCap removal method as per attached video. Note: Please attempt this carefully - blunt implements preferred!
To reduce the frequency of this occurring, we suggest checking that you are using a capsule compatible with your model of machine, and that all gaskets, o-rings etc (dependant on the product) are correct positioned before use.
