How to fix 'Clean brewing unit' message on my Bosch BCM8450UC/03?

The 'Clean brewing unit' message on your Bosch Coffee Maker indicates that the brewing unit is soiled or there is too much ground coffee in it, or the mechanism of the brewing unit is stiff. You should clean the brewing unit and avoid placing more than two level measuring spoons of ground coffee in the drawer.
