Samsung Washer Drain Pump Parts — Models & Compatibility

Your Samsung front-loader won't drain, makes grinding noises during the spin cycle, or you've found water pooling under the machine. The DC31-00054A drain pump assembly is the OEM-compatible replacement for over 20 Samsung, Kenmore, and Maytag washer models that use brushless DC pump motors. This hub covers everything you need to verify compatibility and understand what you're getting into before ordering.

Is This the Right Part for Your Model?

The model number on Samsung front-loaders is typically found on a sticker inside the door frame or on the back panel near the water inlet connections. Cross-reference your model number against the compatibility list below — this pump replaces original part numbers DC31-00016A, AP4202690, PS4204638, and 62902090. If you've got a WF series front-loader manufactured between 2008-2015, there's a very good chance this is your pump.

About This Replacement Part

The DC31-00054A is a brushless DC motor pump assembly that handles both drain-out and recirculation functions on Samsung's front-load washers. The most common failure mode we see is motor flooding — water gets past the seal and cracks the rotor on both sides, causing the pump to hum but not spin. You'll hear it trying to work, maybe making clicking or grinding noises, but water stays in the tub. Other times the pump just develops leaks around the housing or the motor windings burn out completely. Samsung uses this same pump design across multiple model series (WF210, WF219, WF328, WF330, WF337, WF419, WF448), which is why one part number covers so many machines.

What Makes This Repair Challenging

Here's what you need to know upfront: Samsung didn't make this pump easy to access. On models like the WF438AAR and WF448AAP, the pump isn't accessible from the back panel — you'll need to remove the top, control panel, door assembly (including the rubber boot and door lock), and entire front cover to reach it. Budget 30-60 minutes if you're methodical, longer if it's your first time. The plastic housing around the pump is fragile — one user described cutting the black plastic retaining flanges on the old pump to slide it out in two pieces rather than risk cracking the mount. When installing the new pump, you'll need to push the entire assembly back about an inch toward the rear of the washer, then lift up and out to clear the mounting screws.

Tools You'll Need

• Phillips and flathead screwdrivers
• 1/4" socket set (8mm and 10mm sockets most common)
• Needle-nose pliers for hose clamps
• Towels and a shallow pan (you'll drain residual water)
• Phone camera to document hose and wire connections

Installation Reality Check

One of our customers put it perfectly: "Good news: this pump is the correct part for the Samsung front loader WF438AAR. Bad news: the instructional video was inaccurate in every possible way." Most generic videos show rear access, which doesn't apply to these models. You'll be removing the soap dispenser drawer, disconnecting the control panel connectors, taking off the spring retainer for the front rubber seal, removing door latch screws, and dealing with the plastic drain area housing. It's not a simple back-panel-off-and-swap job. That said, the part itself works perfectly when installed correctly — just set aside an afternoon and don't rush it.

Compatible Models

This drain pump assembly fits the following Samsung, Kenmore, and Maytag washer models. If your model number isn't listed but shares the same series prefix (like WF328), it likely uses this pump — verify the part number on your existing pump before ordering.

Symptoms This Part Fixes

• Washer won't drain — water stays in tub after cycle completes
• Grinding, humming, or clicking noises during drain cycle
• Water leaking from underneath the washer during or after use
• Error codes related to drain function (typically dE, d5, or similar)
• Pump motor runs but no water movement

Why This Pump Fails

The brushless DC design is efficient but vulnerable to seal failure. When the shaft seal deteriorates (often due to detergent buildup or hard water deposits), water infiltrates the motor housing and causes the rotor to crack. We've seen units where both sides of the rotor were fractured, leaving the motor unable to generate torque even though it's receiving power. Other failures include bearing wear (causing the noise issues), impeller clogs from coins or small items, and electrical failures in the motor windings. If your pump is leaking externally, that's usually a housing crack or failed outlet gasket rather than a motor issue — but at this price point, replacing the entire assembly makes more sense than trying to rebuild it.

Price and Availability

The DC31-00054A assembly is priced at $38.99, which is significantly less than Samsung's OEM pricing (typically $75-95 through authorized service centers). This is an aftermarket replacement that meets OEM specifications — same mounting points, same electrical connections, same pump capacity. Ships directly from our warehouse, usually arriving within 3-5 business days.
