LG & Kenmore Washer Drain Pump Motor Assembly Parts — Models & Compatibility

Your LG or Kenmore washer won't drain, and you're staring at a tub full of soapy water that won't budge. That humming sound (or complete silence) during the drain cycle means your drain pump motor assembly has likely failed — one of the most common failures in front-load washers. This hub covers the 4681EA2001T drain pump assembly that fits over 50 LG and Kenmore washer models from the WM series, including both top-load and front-load configurations.

Is This the Right Part for Your Model?

The 4681EA2001T drain pump (also sold as AP5328388, 4681EA2001N, 4681EA1007G, or PS3579318) works across LG's WM series and compatible Kenmore models. Your model number is usually located on the inside of the door frame or on a label behind the detergent dispenser drawer. If you've got a WM0642HW, WM1814CW, WM2016CW, WM2101HW, WM2140CW, WM2250CW, WM2277HB, WM2277HS, WM2350HRC, WM2350HWC, WM2450HRA, WM2455HG, WM2487HRMA, WM2487HWM, WM2496HWM, WM2550HRCA, WM2550HWCA, WM2650HRA, WM2650HWA, WM2655HVA, or similar WM-series model, this pump will fit.

About This Replacement Drain Pump

The drain pump motor assembly is what forces water out of your washer's tub through the drain hose during the spin cycle. It's a compact unit with an electric motor attached to an impeller housing — when it runs, it creates pressure that pushes water out. LG's design uses a single-piece assembly that mounts to the bottom of the tub with three to four mounting screws and connects via a wire harness and two large drain hoses. The pump runs multiple times during each wash cycle: after the wash phase, during rinses, and at the final spin. That constant use means the motor bearings wear out, the impeller gets damaged by coins or debris, or the housing develops cracks from vibration stress.

Common Signs Your Drain Pump Has Failed

Most drain pump failures show up as water that won't drain from the tub — you'll open the door after a cycle and find standing water. Sometimes the pump makes a loud humming or grinding noise but doesn't move water. Other times it's completely silent during the drain cycle when it should be running. You might also see an OE error code (drain error) on the display panel. If your washer completes the wash cycle but stops before the final spin, that's another telltale sign the pump can't evacuate the water.

What's Included & Specifications

The 4681EA2001T assembly includes the complete drain pump unit — motor, impeller housing, mounting bracket, and wire connector. It's a direct OEM-equivalent replacement that mounts in the same location as your original pump. The assembly measures approximately 5 inches across and weighs about 1.5 pounds. You'll reuse your existing drain hoses and clamps during installation.

Installation Overview

Replacing the drain pump requires accessing the bottom of your washer. You'll need to unplug the machine, shut off water supply, tip it back or lay it on its front (depending on model), remove the bottom access panel, disconnect the wire harness and drain hoses, unbolt the old pump, and reverse the process with the new unit. The entire job takes 30-45 minutes if you've got basic hand tools and a towel ready for residual water. Make sure to check the pump filter housing for debris before installing the new pump — a clogged filter can cause premature pump failure.

Why This Pump Fails

Drain pumps fail for a few specific reasons. The motor bearings wear out from constant use — they're running several times every wash cycle, and after thousands of cycles the bearings get noisy and eventually seize. Small objects like coins, bobby pins, or buttons can jam the impeller, burning out the motor when it tries to run against the blockage. Hard water deposits can also build up in the impeller housing, restricting water flow and forcing the motor to work harder. Finally, the pump housing itself can crack from vibration stress, especially if the washer isn't level or the suspension system is worn.

Part Numbers & Cross-References

This drain pump assembly replaces these part numbers: 4681EA2001T (current), AP5328388, 4681EA2001N, 4681EA1007G, and PS3579318. If you're finding any of those numbers in your parts search, they're all the same pump — manufacturers just update suffixes for production runs. The 4681EA2001T is the most current version and includes minor design improvements for durability.
