Maintenance Tips
  • Clean grind chamber and chute daily using the built-in cleaning lever to remove retained coffee and prevent stale buildup.
  • Brush and vacuum burr area regularly to clear fines and prevent clogging or uneven grinding.
  • Empty hopper frequently and wipe inside with a dry cloth to avoid oil buildup that affects bean flow.
  • Run grinder cleaner pellets (approved grinder cleaning tablets) periodically to remove internal coffee oils.
  • Inspect burrs regularly for wear; replace when grind becomes inconsistent or slower than normal.
  • Keep discharge chute clean to prevent grinds from “spraying” or backing up into the chamber.
  • Check and clean bag switch area to ensure proper operation and avoid start/stop issues.
  • Do not use water or liquid cleaners inside the grinder—moisture can damage burrs and motor components.
  • Tighten and check hopper alignment after cleaning to ensure proper bean feeding into burrs.
  • Schedule deep cleaning weekly in high-use environments to maintain grind consistency and machine life.
