What is the correct position for the brew assembly?

Hi,

I have opened and rinsed my machine in a similar manner as in this guide, but just washed the brew assembly without taking it apart:

When I reinstall the brew assembly, I mount it in the machine with the ground coffee "cup" in the bottom position.

When starting up, the motor running the brew assembly keeps on running, making the gears grind.

Did I reinstall the bre assembly incorrect, or has something else broken?
