Machine is very noisy during operation, with loud vibration or rattling sounds.

Safety: Unplug before tightening any internal components.

Steps:

• 1. Level the machine: Place the coffee maker on a solid, level surface. Adjust feet if available.
• 2. Check external parts: Ensure the water tank, drip tray, and grounds container are fully seated and not rattling.
• 3. Internal inspection (advanced): Remove the cover and check that the pump and grinder are firmly mounted on their rubber isolators. Tighten any loose screws and add foam padding where appropriate.

Resolution: Replace worn vibration dampers or pump mounts if they have deteriorated.
