You should have an owner's manual that will tell you. But if not, call and get one from the retailer who sold it to you. If the owner's manual doesn't tell you, then call Whirlpool. You spent a lot of money you will get an answer or if you don't call whomever does the warranty work, have them come out, make sure there's no charge and there usually won't be since it's new.
