The Dishwasher Moisture Barrier Kit attaches to the bottom of the cabinets above the dishwasher door to protect your cabinets from moisture damage. This accessory kit can be used with many appliance brands; check your model number to confirm compatibility. Installing this kit will require basic hand tools and novice repair experience. You must unplug the appliance or shut off the house circuit breaker for the appliance before beginning the repair. Helpful Tip: We also recommend using affresh® Dishwasher Cleaner* (item W10282479) to help remove limescale and mineral build-up that can be unsightly and affect your dishwasher s performance. *affresh® brand products are owned and distributed by Whirlpool Corporation.
