Samsung Washer Drain Pump Motor Parts — Models & Compatibility

If your Samsung front-load washer won't drain or you're hearing grinding noises during the drain cycle, the drain pump motor is usually the culprit. This hub covers the DC31-00180A drain pump motor — a direct replacement that fits over 20 Samsung washer models from the WF and WW series, plus it replaces older part numbers DC31-30008D, DC31-00056A, and DC31-30001A.

Is This the Right Part for Your Model?

Your Samsung washer's model number is typically located inside the door frame or on the back panel near the serial number plate. Check your model against our compatibility list below — this pump fits popular series including WW60J, WW70J, WW80J, WW90J, WF1802, WF8804, and WD80K models. If your model number starts with WF or WW and was manufactured between 2012-2018, there's a strong chance this pump will work.

About This Replacement Part

The DC31-00180A is Samsung's updated drain pump motor assembly that improves on earlier designs. It includes the motor housing, impeller, and electrical connections pre-assembled. This pump handles the critical job of expelling water during drain and spin cycles — when it fails, you'll notice standing water in the drum, error codes (often ND or 5E), or the washer stopping mid-cycle. The $89.99 replacement cost beats a service call, and most DIYers can swap this part in under an hour with basic tools.

Signs Your Drain Pump Needs Replacement

Samsung drain pumps typically last 5-8 years before wearing out. You'll know it's time for a replacement when water stays in the drum after a cycle completes, the washer displays drainage error codes, or you hear a humming or grinding noise during what should be the drain phase. Sometimes the pump runs but doesn't actually move water — that's usually a jammed impeller or a failed motor winding.

What's Included

The DC31-00180A comes as a complete pump assembly ready to install. You get the motor unit, mounting bracket, and wire harness connector. No separate impeller or housing pieces to assemble — just unbolt the old pump, disconnect the hoses and wiring, and reverse the process with the new unit.

Need Help Identifying Your Part?

If you're not sure this pump matches your washer, snap a photo of your model number plate and the existing pump's part number label. Our parts team can confirm compatibility — we've helped thousands of Samsung washer owners find the exact pump they need. Most common confusion happens with WA top-load models (which use different pumps) versus WF and WW front-load models (which use this DC31-00180A).
