This Dishwasher Drain Hose Is An Extra Long 12-Ft Hose Used In Cases Where The Sink Drain Is Too Far Away From Your Dishwasher For A Standard Hose. When Replacing, Make Sure To Use Towels To Catch Any Water That Might Leak Out Of The Line. Also Be Sure That The Sink End Of The Hose Is The Correct Size – You Can Cut Down A Larger Sink End If Necessary Before Attaching. This Accessory Can Be Used Across Several Brands; Check To See If Your Model Number Is Compatible. Replacing This Accessory Will Require Basic Hand Tools, Some Disassembly Of The Dishwasher And Novice Repair Experience. You Must Unplug The Appliance Or Shut Off The House Circuit Breaker For The Appliance Before Installing This Part. Also Make Sure You Turn The Water Supply Off To The Dishwasher.
