Maintenance and Cleaning
1. Cleaning the Grinding Chamber
After each use, unplug the grinder. Remove the lid and then twist the grinding chamber counter-clockwise to remove it from the base. Empty any remaining ground coffee. The removable grinding chamber can be washed in warm, soapy water or placed on the top rack of a dishwasher. The Chamber Maid Cleaning System helps dislodge grounds from the chamber walls during removal.
2. Cleaning the Lid and Base
Wipe the lid with a damp cloth. The grinder base should only be wiped with a damp cloth; never immerse the base in water or any other liquid.
3. Storage
Ensure all parts are completely dry before reassembling and storing the grinder. The power cord can be wrapped around the base for compact storage.
