Samsung Washer Drain Pump

Samsung front-load and top-load washers (WF/WA model series) feature VRT Plus vibration reduction, Self Clean+ cycles, and Digital Inverter motors. The drain pump is a Samsung-specific component using the DC part prefix. This guide covers the actual replacement procedure — Samsung-specific access panel layouts, the correct part number, and testing procedures you should perform before and after the repair.

Symptoms That Indicate Drain Pump Failure

• Water remains in the tub after the cycle — the pump cannot evacuate water. Samsung error code 5E (drain error) displays
• Loud grinding or humming during the drain/spin phase — pump impeller jammed by a coin, button, or debris
• Slow drainage — partial impeller wear or blockage in the pump housing
• Water leaking from under the washer during the drain cycle — pump housing seal or hose connection failed
• Error code 5E but the drain filter is clean — the pump motor itself has failed

Run a Samsung diagnostic by pressing and holding specific button combinations (varies by model — check your manual). The display will cycle through error codes stored in memory.

Samsung Part Identification

OEM part number: DC31-00054A — Samsung uses the DA/DC/DD/DG/DE prefix system where the first two letters identify the appliance division (DA = refrigerator, DC = washer/dryer, DD = dishwasher, DG = range/oven, DE = microwave). Find your model number (WF/WA series) on the rating plate inside the door or on the front panel and verify the exact part at samsung.com/us/support/. Samsung frequently revises parts across production runs — always cross-reference with your specific model number rather than relying on a generic part number.

Where to find your model number: Open the door/lid and look on the inside of the door frame or under the lid. Model numbers start with WF/WA.

Both OEM and aftermarket options are available. OEM ensures correct fit and Samsung diagnostic compatibility.

Step-by-Step Replacement

Open the small access door at the bottom-left of the front panel. The drain pump filter cap is there. The pump motor is behind this area.

1. Unplug the washer. Place towels and a shallow pan under the small access door at the bottom-left of the front panel.
2. Open the access door. Turn the drain pump filter cap counter-clockwise slowly — water will flow out. Let it drain into the pan.
3. Remove the filter cap completely and inspect for coins, hair ties, small garments, or debris that could jam the pump.
4. If cleaning the filter solves the problem, reassemble. If the pump still does not drain:
5. Remove the access door panel fully (2-3 Phillips screws). The pump motor is visible behind the filter housing.
6. Disconnect the pump wire harness (2-pin connector) and the drain hose.
7. The pump is attached to the sump with a twist-lock or screws. Remove and replace with new pump (DC31-00054A).
8. Reconnect drain hose and wire harness. Reassemble. Run a drain/spin cycle and check for leaks.

Safety note: If you encounter unexpected resistance or signs of electrical damage (melting, burning), stop and call a professional.

Tools Required

• Phillips #2 screwdriver — for access panel screws
• Towels and shallow pan — for catching water during filter removal (1-2 gallons may drain)
• Pliers — for hose clamps
• Multimeter — test pump motor (5-30 ohms normal). OL = open winding

Samsung-Specific Tips and Common Mistakes

• Samsung front-load washers have a drain pump filter accessible behind a small door at the bottom-left. ALWAYS clean this filter before assuming the pump has failed — coins, hair ties, and bra underwires jam the pump impeller and are easily removed.
• When opening the filter cap, be prepared for 1-2 gallons of water to flow out — have a shallow pan and towels ready. The water may be hot if you just ran a cycle.
• Samsung uses the Spider Arm (aluminum hub connecting the drum to the shaft) which corrodes over time with liquid detergent. If you find metal fragments in the pump filter, the spider arm is corroding — use HE powder detergent to slow this Samsung-specific issue.

DIY or Professional?

This is a moderate repair. The pump is behind the lower access door and is a moderate repair. Always clean the filter first — this solves the problem in over 50% of 5E error cases without needing a new pump.

Consider calling a professional if:

• Metal fragments in the filter indicate spider arm corrosion — a professional can assess the drum assembly
• The pump housing is cracked and leaking — the sump area may also be damaged
• The 5E error persists after pump replacement — the drain hose or standpipe may be blocked

What Happens If You Delay This Repair

A non-functional drain pump leaves clothes sitting in dirty water. The washer cannot proceed to the spin cycle, so clothes remain soaking wet. Continued operation with a jammed pump motor stresses the control board relay. Standing water breeds bacteria and causes odor.

How Long Does a Samsung Washer Drain Pump Last?

A typical Samsung washer drain pump lasts 6-10 years under normal residential use. Samsung's build quality and smart diagnostics help you catch declining performance before complete failure — set up SmartThings notifications if your model supports it.

Factors That Shorten Drain Pump Life

• Foreign objects — coins, hair ties, bra underwires, and small items damage the impeller
• Hard water — mineral deposits on the impeller and housing reduce efficiency
• Soap buildup — excess detergent creates sludge that clogs the pump
• Spider arm corrosion — metal fragments from corroding spider arms damage the impeller

Maintenance Tips to Extend Drain Pump Life

• Clean the drain pump filter monthly — Samsung filter access door at the bottom-left of the front panel
• Check pockets before loading — coins, keys, and small objects are the most common pump killers
• Use HE powder detergent — liquid detergent accelerates Samsung spider arm corrosion, and the metal fragments damage the pump
• Run a monthly Self Clean+ cycle at 60C to prevent detergent sludge buildup

FAQ

How much does it cost to replace a Samsung washer drain pump?

OEM part costs $30-$110. Professional installation adds $80-$170, totaling $110-$280.

Can I replace the drain pump in my Samsung washer myself?

The pump is behind the lower access door and is a moderate repair. Always clean the filter first — this solves the problem in over 50% of 5E error cases without needing a new pump.

How long does a Samsung washer drain pump last?

Typical lifespan is 6-10 years under normal residential use. Regular maintenance and proper use are the biggest factors in reaching that lifespan. Samsung appliances with SmartThings can proactively alert you to declining component performance before complete failure occurs.

What Samsung part number do I need for my washer drain pump?

The primary OEM number is DC31-00054A. Samsung uses the DA/DC/DD/DG/DE prefix system — the first two letters identify the appliance division. Always verify against your specific model number (WF/WA series) at samsung.com/us/support/, as Samsung frequently revises parts across production runs. Using the wrong part can cause fit issues or void warranty coverage.

Is it worth repairing my Samsung washer or should I replace it?

If your Samsung washer is under 8 years old and the drain pump is the only issue, the repair at $110-$280 is typically worthwhile. If the unit is over 10-12 years old or has multiple failing components, compare the total repair cost against a new Samsung washer and choose accordingly.
