Brewing unit won't go back in

The brewing unit of our Melitta Caffeo Solo did not going back in.

I found mentions of the motor not being properly aligned.

The official FAQ states: The motor might not be in the correct position. Check if the water tank is filled and if the drip tray is in place. Turn the appliance OFF and then ON again. Then simultaneously press the button for My-Coffee and the on/off button for more than 2 seconds. The motor will move into the correct position. Insert the brewing unit again and check that it is correctly locked in position.

However, this proposed solution did not reset the motor position in my case.

I found that the locking handle of the brewing unit moves a metal lever.

This metal lever engages a button in the machine.

By carefully pressing this button (i used the handle of a small spoon), the motor reset to the correct position.

Long story short: I don't have a question, and just wanted to post this here for future reference.
