If you're using the sanitize and heat dry, that's fine, it should be able to sanitize your bottles. My points are 1) dishwasher won't reliably clean your bottles, and 2) probably not getting much from Star San addition.
If you want to keep using the dishwasher, make sure you clean the bottles first, make sure dishwasher is as clean as possible (food bits and the like) and I'd say just leave out the Star San and go with the wet heat.
