CLEANING
WARNING - Unplug the grinder before the removal of any panel or grind chamber-housing parts.
1. Clean all exterior surfaces using a damp cloth rinsed in any mild, nonabrasive, liquid detergent. Care should
be taken not to scratch the grinder with any abrasive material.
2. Empty all beans from hopper(s). Plug in the grinder, place an empty bag behind the dispense chute. Press
and release the “START” switch. Run a few cycles until all coffee in the grind chamber is dispensed and
disconnect the grinder from the power source. Remove the bag.
WARNING - Prior to cleaning the grind chamber, unplug the grinder.
3. Remove the two screws and remove the dial plate and selector knob assembly.
4. Slide the burr auger rotor/spring assembly off the motor shaft and disassemble for cleaning.

6. Remove the four screws at the top of the chute and remove the chute. Using a pair of pliers, remove the C-
clips securing the flapper arm to the chute. Remove the flapper securing pins carefully (noting the location
of each flapper spring).
7. Wash all parts in a mild solution of detergent with hot water and a stiff non-metallic bristle brush. Rinse all
parts thoroughly and allow them to air dry before reinstalling.
8. Carefully clean the grind chamber, dial plate assembly, chute opening and dial plate opening with a dry stiff
non-metallic bristle brush. Wipe with a clean cloth that has been soaking in a mild solution of detergent and

dial plate to the burr housing. Refer to the “Adjustment” section of the Operating and Service manual for
