This dishwasher does not come with a moisture barrier. Samsung dishwashers use condensing dry technology. This means that the water gets hot and turns into steam, then when things cool down again and the water droplets form, they form on the cooling stainless steel walls of the dishwasher instead of on your still-hot dishes. Any remaining droplets on the dishes evaporate away, which is easier when the door is left cracked. Thank you for choosing Samsung! ^Lena
