Once I changed the machine parameters, how do I set them back to the original parameters?

You will need to reset to factory settings by following these steps:

Open the machine head and let the used capsule be ejected.

Close the head. Leave the handle in “UNLOCKED” position.

Push the button 5 times within 3 seconds. The button blinks 5 times orange and changes than to steady white.

You can also use the App to do a factory reset.
