Why does my Bosch CTL636E 6 say "Clean brewing unit"?

If your Bosch Coffee Maker display shows “Clean brewing unit”, it means that the brewing unit is soiled, there is too much ground coffee in the brewing unit, or the mechanism of the brewing unit is stiff. In this case, clean the brewing unit and do not place more than two level measuring spoons of ground coffee in the drawer.
