LG Washer Circulation Pump Motor Parts — Models & Compatibility

Your LG front-load washer won't drain, and you're staring at a drum full of soaking clothes. Before you call a service tech charging $200+ just to show up, check if it's the circulation pump motor — one of the most common failure points in LG's high-efficiency washers. This hub covers the EAU61383503 replacement pump motor that fits over 20 LG and Kenmore models from the 3000-5000 series.

Is This the Right Part for Your Model?

First things first: grab your model number. On LG front-loaders, you'll find it inside the door frame or behind the detergent dispenser drawer. It'll look something like "WM3988HWA" or "WM4270HWA." Cross-reference it with the compatibility list below — this pump motor works across multiple series because LG used the same pump design from roughly 2010-2018.

The pump motor assembly (sometimes called the drain pump or circulation motor) sits at the bottom of your washer and does double duty: it circulates water during wash cycles and pumps water out during drain cycles. When it fails, you'll know — standing water that won't drain is the dead giveaway.

About This Replacement Part

The EAU61383503 replaces several older LG part numbers including 4681EA2001V, EAU62263303, and AP5620091 — so if you're finding those numbers in your service manual, this is your part. It's a direct OEM-quality replacement that includes the motor assembly, housing, and electrical connections. The pump pulls 120V AC and moves about 15 gallons per minute when it's working correctly.

This pump fails for predictable reasons: small items (coins, bobby pins, sock fibers) get past the filter and jam the impeller, or the motor bearings wear out after years of use. You'll sometimes hear a humming noise during drain cycles right before it quits entirely. The symptom is straightforward: will not drain. Water sits in the drum, your clothes stay soaked, and the washer throws an OE error code (on models with digital displays).

Compatible Model Series

This circulation pump motor fits the following LG washer series:

• WM3000 Series: WM3770HWA, WM3875HVCA, WM3875HWCA, WM3900HWA, WM3987HW, WM3988HWA, WM3997HWA, WM3998HBA
• WM4000 Series: WM4000HBA, WM4000HWA, WM4070HVA, WM4070HWA, WM4200HBA, WM4200HWA, WM4270HVA, WM4270HWA, WM4370HKA, WM4370HWA, WM4500HBA
• WM5000 Series: WM5000HVA, WM5000HWA

These models span LG's ultra-capacity and mega-capacity lines, including models sold under the Kenmore Elite branding (manufactured by LG). If you've got a Kenmore washer from this era with an LG-manufactured tag, check your full model number against this list.

Installation Overview

Replacing the circulation pump isn't a beginner job, but it's manageable if you're comfortable working with appliances. You'll need to tip the washer on its back (get help — these machines weigh 200+ pounds), remove the bottom access panel, disconnect three hoses (inlet, outlet, and pressure), unplug the wire harness, and unbolt the old pump. The whole job takes about 45 minutes once you've got the washer positioned.

Fair warning: you're going to drain water during this repair. Keep towels and a shallow pan handy. There's always residual water in the hoses and pump housing, even after you run a drain cycle.

Why This Pump Fails

LG's high-efficiency washers use less water, which means lint and debris concentrate more than in traditional washers. Over time, fabric fibers build up in the pump housing and wrap around the impeller shaft. Add in the occasional forgotten screw or wire from a bra strap, and you've got a seized pump motor. The other failure mode is simpler: the motor's internal windings burn out after 8-10 years of regular use. You'll smell it if that's the case — burnt electrical components have a distinct odor.

Check your washer's pump filter (usually accessed behind a small panel at the bottom front) every six months. Pull it out, clean the debris, and you'll extend the pump's life significantly. Most people never touch this filter until something goes wrong.
