Technically, you avoid putting your cookware with non-stick coating in your dishwasher. This is because you don’t want to have your nonstick feature be ruined by the dishwashing process or the soap your dishwasher uses. Though there are cookware brands that pride themselves in being dishwasher-safe. So, check the manufacturer’s manual all the time before deciding. Remember that the longevity of the product heavily relies on your maintenance too!
