Apr 26, 2010· My Jura S9''s grinding unit clogged (due to Pete''s coffee beans that were apparently too gooey. Seems like this shouldn''t be so easy to do, BTW) I''ve cleaned the grinder out with a brush, vaccuum and lastly with compressed air. The unit grinds about 1/3 of what it should now, and produces wet grinds in the tray.
