Washer Not Circulating Water? Samsung Recirculation Pump Motor DC31-00181C — Restore Wash Performance Fast
Poor wash results and weak water circulation in your Samsung washer are often caused by a failed recirculation pump motor. In most Samsung front-load washers, the recirculation pump draws water from the sump and sprays it back through the drum during the wash and rinse cycles. When it fails, wash water stops circulating, cleaning performance drops sharply, and the washer may log a pump-related fault code. ⚡ Common failure point in Samsung-built front-load washers. Part DC31-00181C is the genuine OEM Samsung replacement that restores full wash-water circulation and normal washing performance.
🇺🇸 Matching U.S. Part Number: DC31-00181C
❓ Is This the Right Part?
This is the correct fix if ALL of the following are true:
- ✔ Washer powers on and the drum spins normally
- ✔ Drain function works — water exits the tub after the cycle
- ✔ Water supply confirmed — inlet valves open and fill correctly
- ✔ ONLY problem is weak or absent water circulation during wash or rinse

Samsung front-load washers contain both a recirculation pump and a separate drain pump. While the washer is open for service, inspect the drain pump (DC31-00054A or equivalent for your model) for wear, debris or impeller damage — replacing both at the same time eliminates a second service call if the drain pump is marginal.
⚙️ Installation
Skill Level: Moderate — 45 to 75 minutes. Disconnect electrical power and shut off the water supply before servicing. Access the pump by removing the front lower panel or tilting the washer back depending on model. Disconnect the wiring harness and hose clamps, swap the pump motor, reconnect all hoses and wiring, and run a short cycle to confirm circulation is restored.

Confirm the complete model suffix and revision — Samsung washers may contain separate drain and recirculation pumps that look similar but perform different functions.
💡 Pro Tip
DC31-00181C is the recirculation pump motor — it circulates water through the drum. The drain pump (a separate part) removes water from the tub at the end of the cycle. Both pumps are located near the sump and look similar. Confirm which pump is faulty before ordering. If the washer drains normally but washes poorly, the recirculation pump is the likely cause.
