Dishwasher Not Draining? Drain Hose W11551233 – Fix Standing Water Fast

If your KitchenAid or Maytag dishwasher won't drain or is leaking water onto the floor, a failed drain hose is the most likely cause. In most KitchenAid and Maytag dishwashers, the drain hose carries wastewater from the pump to the sink drain or garbage disposal. When it cracks, kinks, or clogs, the dishwasher can't complete the drain cycle — water backs up in the tub, cycles stall, or dirty water leaks under the unit. ⚡ Common failure point in KitchenAid-built dishwashers. Part W11551233 is the genuine OEM replacement that restores full drain function with no modification required, directly superseding W11036161.

❓ Is This the Right Part?

This is the correct fix if ALL of the following are true:

• ✔ Dishwasher powers on and runs cycles normally
• ✔ Wash and rinse functions work correctly — only draining fails
• ✔ Drain filter and sump are clean and unobstructed
• ✔ Garbage disposal or sink drain connection is clear and functional
• ✔ ONLY problem is standing water in the tub, a drain error code, or water leaking from under the unit during the drain cycle

🔧 Common Symptoms

• Dishwasher not draining — standing water in the bottom of the tub after the cycle ends
• Drain cycle runs but water level doesn't drop
• Water leaking under or beside the dishwasher during or after the drain cycle
• Wet floor under the sink cabinet — hose leaking at the pump or drain connection
• Dishwasher stops mid-cycle with a drain error (e.g. F8E1, 6-2, or similar)
• Gurgling, slow drain sounds, or dirty water backing up into the tub between cycles

✔ If these symptoms match, the drain hose is the most likely failed component in the system.

✔ In most cases, replacing the drain hose restores normal drain operation immediately.

⚙️ Installation

Skill Level: MODERATE — 20 to 40 minutes. Disconnect power at the breaker and turn off the water supply before starting. Access the drain hose from under the sink at the disposal or drain connection and from inside the dishwasher toe-kick panel. Note the hose routing and clamp positions before removing — photograph if needed. Loosen clamps at both ends, slide the old hose off, and route the new W11551233 in the same path. High-loop installation required: route the hose up as high as possible under the counter before dropping to the drain connection to prevent backflow — secure the loop with a cable tie to the underside of the counter. Tighten all clamps, restore power and water, and run a short cycle while watching both connection points for leaks.
