My Whirlpool Quiet Partner 1 always has water on the indside door when I unload it. My silverware basket is in the door, so my utensils are wet. Is this a defect in the dishwasher or is my drain line responsible? My dishwasher is only 6 months old!

My Whirlpool Quiet Partner 1 always has water on the indside door when I unload it. My silverware basket is in the door, so my utensils are wet. Is this a defect in the dishwasher or is my drain line responsible? My dishwasher is only 6 months old! does it have the vent? Hook up together with the garbage grinder... it could be that the discharge hose in not correctly install, so the water is backing up... loop the hose so it will be higher than the grinder or the drain
