XPARTCO DC31-00187A Washer Drain Pump Motor
The XPARTCO DC31-00187A is an aftermarket replacement washer drain pump motor compatible with select Samsung front-load and top-load washers in the WA4, WA5, WF2, WF3, WF4, and WF5 series, as well as select Kenmore washers built on the Samsung platform. The drain pump motor drives the impeller that expels water from the washer tub during the drain phase of each wash cycle. When the motor fails, the washer will not drain, will leave standing water in the tub, stop mid-cycle, or display error codes 5C, SE, SC, 5E, or SUDS.
This motor-only assembly includes the pump motor, impeller, and replacement O-ring. Rated 120V, 60Hz, 80W, 1.1A (CL.F), with a 30-minute on / 30-minute off duty cycle. Dimensions: 4-1/4"L x 3"W x 4-1/4"H in gray/white/black plastic, metal, and rubber housing. The DC31-00187A is the motor component that installs into the existing pump housing on compatible Samsung washers — the pump housing (DC97-20621C assembly) is reused from the old pump, making this a motor-only swap rather than a complete pump replacement. It directly replaces DC31-00187D, DC31-00178A, DC31-00178D, PX3516-01, 03DC3100187A, 4958525, AP6977256, EAP9605762, PD00056512, PS9605762, and PS1274262. Installs in 20–30 minutes with basic hand tools.

Note: The DC31-00187A is the pump motor only — it installs into the existing pump housing (DC97-20621C assembly) which is retained from the old pump. The housing is not replaced. Check and clean the drain filter before replacing the pump motor — a clogged filter is a common cause of drain errors that doesn't require motor replacement.

Installation Notes
⚠️ Unplug Washer and Shut Off Water Before Starting — Wear Gloves Disconnect power and turn off the water supply before beginning. Wear work gloves — there are sharp edges inside the washer cabinet. For front-load models: remove the lower front access panel to expose the pump housing and filter. Drain residual water via the filter drain hose (have a shallow pan ready). Disconnect the wire harness from the motor. On most Samsung front-load models, the motor assembly twists out of the pump housing by rotating counter-clockwise — do not force it. Remove the old motor, note the O-ring position, and install the new O-ring from this kit onto the new DC31-00187A motor. Insert the new motor into the housing and twist clockwise to lock. Reconnect the wire harness. Reinstall the lower panel, restore power and water, and run a drain/spin cycle to confirm drainage. For top-load models: access through the lower front panel or by tilting the washer on its side depending on model. Tools needed: Phillips screwdriver, pliers, shallow pan, towels, work gloves.
Frequently Asked Questions
What is the difference between DC31-00187A and DC97-20621C?
The DC31-00187A is the drain pump motor — the electrical component that drives the impeller. The DC97-20621C is the complete drain pump assembly, which includes the motor plus the outer pump housing, hose connection ports, and mounting hardware. When you order the DC31-00187A, you replace only the motor and reuse the existing DC97-20621C pump housing. When you order the DC97-20621C, you replace the entire assembly including the housing. Both resolve the same drain fault — the DC31-00187A is the more targeted repair when the housing is in good condition.
What error codes indicate a drain pump motor failure?
Error codes 5C, SE, SC, 5E, and SUDS on compatible Samsung washers all indicate a drain fault — the washer was unable to drain within the expected time. Before replacing the motor, clean the drain filter/coin trap at the lower front panel. A clogged filter is one of the most common causes of these error codes and does not require motor replacement. If the filter is clear and the codes persist, or if the pump is making loud noise or is completely silent during the drain phase, the motor needs replacement.
What is the difference between DC31-00187A and DC31-00178A?
These are cross-references for the same or very similar Samsung drain pump motor used across different Samsung washer generations. The DC31-00178A was used on earlier Samsung models and the DC31-00187A is the current version. Both are commonly listed as interchangeable replacements for each other in Samsung washer drain pump repair. The DC31-00187D and DC31-00178D are also variants of the same motor from different production runs.
Should I clean the filter before replacing the pump motor?
Yes — always check and clean the drain filter first. On Samsung front-load washers, the filter is accessible behind the lower front kick panel, typically on the right side — remove the cap slowly and drain water into a shallow pan first. Lint, coins, debris, and hair are very common causes of Samsung drain error codes that are completely resolved by cleaning the filter without any parts replacement. If the filter is clear and the error codes persist, the pump motor is the next component to replace.
Is this an OEM or aftermarket part?
This is an aftermarket replacement part built to OEM-equivalent quality standards. It is not a genuine Samsung OEM part, but is manufactured to match the electrical specifications and performance of the original DC31-00187A drain pump motor.
