How do I clean the grinding burrs and coffee grinds chute?

The LCD screen will display 'CLEAN COFFEE CHUTE' when cleaning is needed. Unlock and remove the bean hopper, open the swing-out door, remove the plug from the power outlet, remove any remaining beans from the grinding chamber, and use the provided cleaning brush to thoroughly remove coffee grinds buildup. Replace the upper burr by aligning the arrow with the 'ALIGN' mark and turning counter-clockwise until it clicks. (Pages 23-24)
