DIAGNOSIS A loud grinding noise typically means a piece of ice or a foreign object is stuck in the auger (the spiral mechanism that pushes the ice out). This is a common jam.
FIX Yes, unplug it immediately to prevent damage. Let it sit for 30 minutes so any ice jam can melt slightly. Then, open the top and remove the ice basket. Look into the ice drop chute. You might see a chunk of ice or even a small piece of debris. Using a plastic utensil (like a spoon handle), gently try to dislodge it. Never use metal. Once cleared, plug the machine back in and start a cycle. The noise should be gone.
IF THAT DIDN'T WORK If the noise persists after clearing visible obstructions, the issue could be with the auger motor or gearbox. For that, you'd need to contact EUHOMY support, as it's an internal mechanical fault.
HEADS UP This is why it's crucial to use the machine on a level surface. If it's tilted, ice can form unevenly and cause the auger to jam more easily.
