7 Before you slide the brewing unit back into the machine, make sure
the two reference signs on the side match. If they do not match,
perform the following step:
- Make sure the lever is in contact with the base of the brewing unit.
8 Make sure the locking hook of the brewing unit is in the correct
position.
Note: You can find the locking hook on the back of the brewing unit (the side
without the word "push"), at the top of the horizontal edge.
- To position the hook correctly, push it upwards until it is in uppermost
position.
