Samsung Dishwasher Fan Replacement — Complete Repair Guide
Samsung dishwashers (DW model series) integrate SmartThings diagnostics and features like WaterWall spray technology and Zone Booster nozzles, but when the fan fails, you need specific Samsung procedures — not generic dishwasher advice. This guide covers the DD31-00013A replacement with Samsung-specific access procedures, the DD-prefix part numbering system, and the diagnostic steps that help you confirm the failure before spending money on parts.
Symptoms That Indicate Fan Failure
- Dishes still wet after the dry cycle — the fan is not circulating air to evaporate moisture
- No audible whirring during the last 15-20 minutes of the cycle — fan should be running during the dry phase
- Condensation drips on the floor when the door is opened — fan not pulling moisture through the vent
- Musty odor from the dishwasher — inadequate air circulation allows bacteria growth
- AutoRelease Door opens but dishes are still drenched — the assist fan motor is not working
Samsung dishwashers display error codes (HE, 5E, 4E, OE, LE) that narrow the diagnosis. Check the display before opening any panels.

Samsung Part Identification
OEM part number: DD31-00013A — 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 (DW series) on the rating plate top of the door or tub 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 and check the rating plate on the inside edge of the door or on the tub side wall. Model numbers start with DW.

Step-by-Step Replacement
Turn off breaker. Remove inner door panel (8-10 screws). Fan is at the door top or tub top.
- Turn off breaker. Remove inner door panel (8-10 Torx T20 or Phillips screws).
- The fan is at the top of the door or tub — visible once the inner panel is removed.
- Disconnect the fan motor wire harness (2-pin).
- Remove 2 Phillips mounting screws and extract the fan assembly.
- Install new fan (DD31-00013A), mount, reconnect harness.
- Reassemble inner door panel ensuring the vapor gasket seats properly.
- Restore power. Run a cycle with Dry option enabled. Listen for fan in the last 15-20 minutes.
Safety note: If you encounter unexpected resistance or signs of electrical damage (melting, burning), stop and call a professional.
Tools Required
- Torx T20 driver — for door panel screws
- Phillips #2 screwdriver — for fan mounting
- Multimeter — test fan motor winding (50-200 ohms). OL = open motor

Samsung-Specific Tips and Common Mistakes
- Not all Samsung dishwashers have a drying fan — budget models use condensation drying only (no fan). Check your model specs before ordering.
- If your Samsung has a plastic tub, condensation drying works poorly because plastic does not cool and condense moisture like stainless steel. These models rely more on the fan and rinse aid.
- Rinse aid is more impactful for drying than the fan — it reduces water surface tension, allowing water to sheet off dishes.
DIY or Professional?
This is a moderate repair. Requires removing the inner door panel. The fan is 2 screws and a connector. The challenge is handling the door panel without damaging the vapor gasket.
Consider calling a professional if:
- Unsure whether your model has a drying fan or uses condensation drying only
- Dishes wet even with working fan — heater, rinse aid, or thermostat may be the issue
- Vapor gasket between door panels is damaged

What Happens If You Delay This Repair
Without the fan, dishes remain wet with water spots. Trapped moisture promotes bacteria and the musty dishwasher odor that is hard to eliminate.
How Long Does a Samsung Dishwasher Fan Last?
A typical Samsung dishwasher fan lasts 8-12 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.
Is It Worth Your Time?
The average DIY appliance repair takes 4-6 hours of research, troubleshooting, and parts ordering — with no guarantee of a correct diagnosis. Our technician diagnoses the issue in about 30 minutes — same-day appointments available.

Factors That Shorten Fan Life
- Motor runtime — longer dry cycles accumulate more hours on the motor
- Steam exposure — the motor operates in high moisture, accelerating bearing wear
- Dust and lint — the vent draws kitchen air with debris that unbalances the fan blade
Maintenance Tips to Extend Fan Life
- Clean the vent opening every 3 months — lint restricts airflow
- Use rinse aid — reduces the drying burden on the fan
- Run with Heated Dry or Extra Dry option enabled
The Risk of Getting It Wrong
A wrong diagnosis often turns a simple fix into a costly replacement. Without proper diagnostic tools, you might replace the wrong part — or cause additional damage. Our free diagnostic eliminates the guesswork.

How long does a Samsung dishwasher fan last?
Typical lifespan is 8-12 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 dishwasher fan?
The primary OEM number is DD31-00013A. 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 (DW 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 dishwasher or should I replace it?
If your Samsung dishwasher is under 8 years old and the fan is the only issue, the repair at $105-$225 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 dishwasher and choose accordingly.
