Whirlpool NEW OEM Dishwasher Water Inlet Fill Hose W10878507 KitchenAid NOS 0810

Whirlpool OEM Dishwasher Water Inlet Fill Hose — Part Number W10878507
Brand: Whirlpool | Condition: New Old Stock (NOS)

You are purchasing a genuine Whirlpool OEM Dishwasher Water Inlet Fill Hose (Tubing), part number W10878507. This accordion-style black plastic hose connects the water inlet valve to the water inlet port on the side of the dishwasher tub — delivering water from the inlet valve into the tub during wash and rinse cycles. A cracked, kinked, split, or leaking fill hose can cause water leaks under or around the dishwasher, reduced water pressure inside the tub, dishes not being cleaned properly, or water supply error codes. Tools required for installation: 1/4 in. nut driver, Channellock pliers, and Phillips screwdriver. Reuse existing clamps when securing the new hose. This is an authentic factory original part — never installed, never used.

Condition Details: This is a New Old Stock (NOS) part. The fill hose itself is in new, uninstalled condition. As is common with NOS inventory, the original packaging may show signs of age, including shelf wear, dust, or minor cosmetic blemishes on the bag or box. The part is new and fully functional.

⚠ Important: Unplug the dishwasher and shut off the water supply before installing this part. Wear work gloves to protect your hands during installation.
