Depends on the smell. What does it smell like?
A dishwasher can cause a bad smell at the kitchen sink. most of the time it is either the disposal it self, or drain tube is full of food by material, between disposal and baffle tee, or if have or had leaks could be coming from under cabinet, mold and bactieria growing
old dust or cat piss.
