Your garbage disposal is different from your actual garbage can. Not all food scraps and liquids are meant to be poured into your disposal. To prevent clogs and disposal jams, you should not put in tough or fibrous food scraps, potato peels, grease and oil, and pits and other hard object.
In case you still damage the garbage disposal and it is not running anymore - there is a reset button underneath the garbage disposal that you can push, please confirm if it is working.
Otherwise contact the home wach.
