This Dishwasher Drain Hose Extension 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. Installing this accessory will require basic hand tools, some disassembly of the appliance and novice repair experience. You must unplug the appliance or shut off the house circuit breaker before installing this accessory. Also make sure you turn off the water supply under the sink. Helpful Tip: We also recommend using affresh® Dishwasher Cleaner (item W10282479) once a month or as needed, to help remove limescale and mineral buildup that can affect your dishwasher's performance. *affresh® brand products are owned and distributed by Whirlpool Corporation.
