Samsung Washer Recirculation Pump Motor Parts — Models & Compatibility

The DC31-00181C recirculation pump motor is a critical component in Samsung's top-load and front-load washer lineup, responsible for circulating water during wash cycles. If your Samsung washer isn't filling properly, makes grinding noises during operation, or displays error codes related to water flow, this pump motor is often the culprit. This hub covers compatibility across Samsung's WA and WF series washers from 2012-2018.

Is This the Right Part for Your Model?

You'll find your model number on a sticker inside the washer door frame or on the back panel near the water connections. Samsung model numbers typically start with WA (top-load) or WF (front-load) followed by numbers and letters indicating capacity and features. Cross-reference your complete model number with the compatibility list below — the DC31-00181C replaces several older pump motors including DC31-00030E, DC31-00030J, DC96-01113G, and DC31-30008F.

About This Replacement Pump Motor

Samsung's recirculation pump motor is designed to maintain consistent water pressure throughout the wash cycle, ensuring detergent distribution and proper cleaning performance. This component typically sees heavy use in households that run multiple loads daily, with high-capacity models like the WA52J8700AW and WA56H9000AP placing additional strain on the pump due to increased water volume. The DC31-00181C is an OEM-equivalent replacement that restores original performance specifications.

Common signs you need this part: washer won't advance past the fill cycle, unusual humming or buzzing from the pump area, error codes like 4E or 4C (water supply issues), or visible water leaks beneath the washer cabinet. The pump motor connects directly to your washer's control board and pressure switch system, so proper installation requires disconnecting power and water lines before beginning any repair work.

Installation Considerations

Replacing the recirculation pump motor requires accessing the washer's base or rear panel depending on your model type. For top-load washers, you'll typically need to remove the front or rear access panel and disconnect the pump's wire harness and hose clamps. Front-load models usually require tilting the washer and accessing the pump from underneath. Always disconnect power at the breaker and turn off water supply valves before starting any repair.

Why This Part Fails

Recirculation pump motors fail due to bearing wear from continuous operation, calcium buildup in hard water areas, and electrical issues from power surges or control board malfunctions. Samsung's high-efficiency washers run the pump more frequently than traditional models, which accelerates wear patterns. If you've noticed your washer taking longer to fill or not filling at all, the pump motor has likely lost efficiency and needs replacement rather than attempting to clean or repair it.
