This Part Fixes These Problems

Washer Won't Drain

Water remains standing in the tub after the cycle ends. A failed pump motor or clogged impeller prevents water from being expelled through the drain hose.

F9E1 / Long Drain Error Code

The control board detects the tub has not drained within the allotted time and displays an F9E1 fault. A defective drain pump is the primary cause of this error on Whirlpool and Maytag top-loaders.

Loud Buzzing or Grinding Noise

A humming, buzzing, or grinding sound during the drain phase indicates the pump motor is seizing or the impeller is jammed with debris, requiring pump replacement.

Clothes Come Out Soaking Wet

If the washer appears to spin but clothes remain excessively wet, the pump is failing to remove residual water from the drum before or during the spin cycle.

Washer Stuck in Drain Cycle

The machine continuously attempts to drain without advancing to the spin or rinse cycle. This is caused by the control board repeatedly signaling a drain pump that is not functioning properly.

OEM vs Aftermarket Drain Pump for Whirlpool Washers: Honest Comparison (W11399437)
May 29, 2026

Product Description

Why Choose Our W11399437 Washer Drain Pump Assembly?

🔧
Built to OEM SpecificationsEngineered to exact OEM dimensions — 120V 60Hz 1.2A CL.F rating — for a direct drop-in fit with zero modifications required on compatible Whirlpool, Maytag, Kenmore, Crosley, and KitchenAid top-load washers.
💧
Restores Full Drain PerformanceThe impeller-driven pump forces water through the drain hose at full capacity, eliminating standing water in the tub, slow-drain conditions, and incomplete spin cycles caused by a failed pump motor.
🛡️
Reinforced High-Grade ConstructionConstructed from reinforced high-grade plastic with a robust internal motor, this pump is rated for continuous duty cycles (10 min ON / 50 min OFF) and is rigorously tested before shipment to ensure long-lasting reliability.
🔁
Wide Cross-Reference CoverageDirectly replaces OEM part numbers W11259498, W10536347, PD00058225, AP6974144, PS12731241, EAP12731241, and 4961028 — covering multiple production revisions of this pump across Whirlpool brand families.
⚡
Clears F9E1 & Drain Error CodesA failed pump is the leading cause of F9E1 (long drain) fault codes on Whirlpool and Maytag top-loaders. Replacing with this unit resolves the fault at the root cause, restoring normal cycle operation immediately.
🕐
30-Minute DIY InstallationNo specialist skills required. Disconnect power, remove the back panel, unscrew the pump from under the roller, unplug the harness, and reverse the steps — most repairs completed in under 30 minutes with basic household tools.

💡 Pro Tip: How to Confirm Your Drain Pump Has Failed

Your part is likely the culprit if you notice any of the following:

⚠️ Washer displays F9E1 error code or gets stuck in the drain cycle

⚠️ Standing water remains in the tub after the cycle ends

⚠️ Loud buzzing, grinding, or humming noise during the drain phase

⚠️ Clothes come out soaking wet — drum spins but water won't expel

🔍 Diagnostic Tip: Set your multimeter to continuity mode and probe the drain pump motor terminals. No continuity = confirmed failed pump. Also check for 120V reaching the pump during the drain cycle — if voltage is present but the pump won't run, replacement is your only fix. Drain pumps are not repairable and must be replaced as a unit.

Questions & Answers

Will this pump fix the F9E1 error code on my Whirlpool WTW5100HC1?
Answered by Support Team  ·  Mar 15, 2024
Yes. The F9E1 error code indicates a long-drain fault, and a failed drain pump is the most common cause. Before replacing, check for blockages in the drain hose and filter. If the hose is clear but the pump does not respond or you hear it humming without pumping, replacing with this W11399437 unit will resolve the error. Use a multimeter to confirm — no continuity across the pump motor terminals confirms failure.
Does this part replace W11259498 directly?
Answered by Support Team  ·  Nov 20, 2023
Yes. W11399437 is the updated superseding part number for W11259498. Whirlpool issued W11399437 as the current production replacement for W11259498 during its production cycle update. Both numbers describe the same pump assembly — this aftermarket unit is engineered to the same 120V 60Hz 1.2A specification and is a direct physical and electrical replacement.
How do I know if my drain pump is bad versus a clogged drain hose?
Answered by Support Team  ·  Jan 8, 2025
Start by removing and visually inspecting the drain hose for kinks, blockages, or debris buildup. Also check the pump filter/inlet for sock lint or coins. If the hose and filter are clear, test the pump motor with a multimeter set to continuity mode — probe across the motor terminals. No continuity confirms the motor has failed internally and the pump must be replaced. If you hear the pump humming loudly but no water moves, the impeller is likely seized.
Is this compatible with Maytag MVW6230HW2 and MVW5430MW0?
Answered by Support Team  ·  Jul 22, 2024
Yes. Both the MVW6230HW2 and MVW5430MW0 are confirmed compatible models for the W11399437 drain pump. This pump covers the majority of Maytag top-load washers from the MVW4505, MVW5035, MVW5430, MVW5435, MVW6200, MVW6230, MVW6500, MVWC565, and MVWX655 series. Always verify your full model number before ordering to ensure proper fit.
How long does this repair typically take and do I need special tools?
Answered by Support Team  ·  Feb 10, 2026
Most DIYers complete this repair in 20–30 minutes. You will need a Phillips screwdriver to remove the back access panel, pliers for the hose clamps, and a bucket for residual water. No special appliance tools are required. The pump secures via standard mounting screws and a plug-in harness connector. Always disconnect power and water supply before beginning — wear work gloves as hose clamps and sheet metal edges can be sharp.

We typically respond within 1 business day. Include your appliance model number for the fastest answer.
