This Dishwasher Drain Hose Extension measures 78.74" L and sends waste water from the drain hose loop to the house drain during your appliance's operation. This accessory is compatible with most dishwasher brands and models and will be needed if your appliance is more than the standard distance away from the house drain; check to see if your model number is compatible. Replacing this part will require basic hand tools, some disassembly of the dishwasher and novice repair experience. 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.
