no function and overheating

@hammedtalus1335 not quite sure how this "not functioning and overheating" works, since if it is not functioning it should not be overheating. Now, it is possible that your grinders motor is still pulling amps but not rotating because of a seized bearing. You will have to take your grinder apart and have a look at the bearings. It is fairly common that the bearings either wear out or get gummed up by debris with heavy use of the grinder.

To work on your grinder use something like this video Once you have it apart post some well focused images of what you find out, with your question. That way we can see what you see and hopefully help you out further. 기존 질문에 이미지 추가하기

While you work on your grinder, take lots of pictures. Once you are done with it, take those pictures and create a guide for iFixit. That will help the next person that has a device with the same issues as you do. It's easy and fun to create these guides. https://ifixit.com/Guide/new The iFixit community will appreciate this.
