This Dishwasher Water Inlet Tubing carries water from the water inlet valve of the dishwasher to the tub. If the existing part is damaged and causing reduced water pressure, you may notice that your dishes aren't being cleaned properly. Replacing this part may alleviate the issue. The tube attaches to the bottom of the upper rack. Installing this part will require basic hand tools, some disassembly of the dishwasher and novice repair experience. Remember to unplug the dishwasher or shut off the house circuit breaker for the appliance before installing this part. Use caution when removing any pieces of hardware to prevent dropping them inside the sump at the bottom of the dishwasher. 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.
