Miele ice maker making loud knocking, banging, or rattling noises during operation

Safety: Disconnect power before placing hands near moving parts.

• Identify noise source: Listen carefully to determine if the noise comes from the ice bin area, rear of the unit, or inside the cabinet.
• Check ice bin: Remove the bin and inspect the auger and crusher for jammed or oversized ice chunks. Break up clumps and discard misshapen ice.
• Tighten mounts: Verify that the ice maker assembly and auger motor bracket are securely fastened to the cabinet.
• Secure water lines: If water lines are rattling against the back panel, secure them with foam or clips.
• Replace noisy motor: If the auger motor or fan makes grinding or squealing noises even when unloaded, replace the motor.

Note: Some minor cracking sounds during defrost or ice release are normal, but persistent loud banging is not.
