Maintenance Tips

• Daily hopper cleaning: Empty beans and wipe hoppers with a dry or slightly damp cloth to prevent oil buildup, rancid flavors, and hopper clogging.
• Clean grind chamber daily (critical): Run grinder until empty, then brush out burr chamber and chute to remove coffee dust and prevent stale residue buildup.
• Brush burrs regularly: Use a dry, non-metal brush to clean both stationary and rotating burrs—this maintains grind consistency and portion accuracy.
• Check portion calibration: Verify grind time settings for each hopper; incorrect calibration directly affects dose consistency and brew strength.
• Inspect burr wear: Replace burrs as a matched set when grind becomes inconsistent or slower—worn burrs reduce extraction quality and increase heat.
• Deep clean every 3–6 months: Disassemble burr assembly, rotor, and chute to remove compacted oils and fine grounds that affect motor load.
• Keep sensors clean: Ensure Smart Funnel/BrewWISE communication area is free of dust for accurate recipe recognition and dosing.
• Avoid moisture exposure: Never wash internal components with water—moisture damages bearings and motor components.
• Check bag switch function: Ensure grinder stops properly when funnel is removed to avoid overrun and safety issues.
• Prevent overheating: During high-volume use, allow short cooling intervals to protect the motor and reduce thermal shutdown risk.
