Samsung Washer Not Draining? Drain Pump DC31-00187A – Fix Drainage Failures Fast
A failed drain pump is the most common reason a Samsung front-load or top-load washer won't drain, leaves standing water, or stops mid-cycle. In most Samsung washers, the drain pump is responsible for expelling water at the end of every wash and spin cycle. When it fails, water sits in the drum, cycles abort, and error codes appear. ⚡ Common failure point in Samsung front-load and top-load washers. Part DC31-00187A is the genuine OEM drain pump that restores full drainage immediately — no modification required. Premium XPart aftermarket option also available.
❓ Is This the Right Part?
This is the correct fix if ALL of the following are true:
- ✔ Washer powers on and the cycle starts normally
- ✔ Wash and rinse functions appear to run correctly
- ✔ Water supply and inlet valve confirmed OK
- ✔ Door latch and lid switch function correctly
- ✔ ONLY problem is water not draining, standing water in drum, or drain-related error codes (5E, 5C, E2)

⚠️ Recommended While Repairing:
While the pump is out, check the drain filter and pump housing for debris, coins, or lint buildup — a blocked filter is often what caused the original pump failure. Clearing the filter at the same time prevents the new pump from failing prematurely.

⚙️ Installation
Skill Level: MODERATE — 30–45 minutes. Disconnect power and turn off the water supply before beginning. For front-loaders, access the pump through the lower front panel or by tilting the machine back; for top-loaders, the pump is typically accessed from underneath. Disconnect the wiring harness and hose clamps, swap the pump, and reconnect. Run a short drain cycle to confirm no leaks before reassembly.
💡 Pro Tip
Check the Drain Hose & Filter Before Condemning the Pump:
A kinked drain hose or clogged pump filter causes identical symptoms to a failed pump and takes 2 minutes to rule out. Always clear the filter and straighten the hose first — if the pump still hums but won't move water, the impeller is seized and replacement is confirmed. This saves an unnecessary part purchase and a second service call.
