1. Empty all beans from hopper(s). Plug in the grinder, place an empty bag behind the dispense chute or
trifecta brew cup. 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 or brew cup.

4. Remove the two screws securing the stationary burr to the grind chamber.

brush to remove any debris around the flapper.
6. 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.
7. Carefully clean the grind chamber, dial plate assembly, and chute 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
hot water.
8. Reinstall the chute onto the burr housing. Reinstall the stationary burr to the grind chamber.
