A message saying ‘no carafe’ may appear if the filter door has been opened while the carafe is in place.
If this is the case, please remove the carafe, open the filter door, close the filter door and place the carafe underneath the machine.
Here is a link to a video showing this: https://www.youtube.com/watch?v=f2W938f2qu4
If the ‘no carafe’ message persists, please check if there are any coffee grinds around the carafe detection button as sometimes if a coffee grind gets stuck, this can affect the reading.
