Unit vibrates excessively or rattles loudly during brewing.

Safety first: Unplug before tightening any screws or inspecting the base.

• Level the unit: Place the coffee maker on a flat, stable surface. Adjust or replace worn rubber feet.
• Secure carafe and lid: Ensure the carafe and lid are properly seated to reduce rattling.
• Tighten screws (advanced): Remove the bottom cover and tighten any loose mounting screws on the pump, heating element, and warming plate.
• Inspect pump mounts: Replace any worn rubber mounts or grommets on the pump to reduce vibration.
