Samsung Dryer 3C Error Code
Drive motor position sensor fault
What this error means
3C on Samsung dryers indicates the drive motor hall sensor did not report valid rotor position at startup. The drum will not turn until the inverter receives position feedback from the motor.
How 3C is detected
When 3C appears on a Samsung dryer, the control board has confirmed that water did not leave the machine within the programmed drain window. On Samsung DVE45R6100W, Samsung DV42H5000EW, and similar variants, the drain pump runs for a fixed interval—often three to seven minutes on washers and dishwashers—while a pressure switch or turbidity sensor verifies the tub or sump is empty. If water remains, the cycle stops to prevent spin with a full tub or overflow on the next fill.
Most 3C calls are resolved without parts: unplug 15 minutes. Restricted drain paths mimic pump failure because the impeller spins against a blocked hose or filter. Document whether the pump hums audibly during the drain step; a humming pump with no water movement points to a clogged filter or kinked hose, while silence may indicate a failed pump motor or loose wiring at the harness.
After clearing blockages, run a short cycle and listen at the drain hose for steady water flow. If 3C returns on the next load with a clean filter and straight hose, measure resistance at the pump motor connector per the service manual for your model before ordering a replacement pump assembly.
Common causes
- Belt off the idler pulley letting the drum spin free while motor stalls
- Object jammed in the blower wheel preventing motor rotation
- Failed hall sensor on the drive motor
- Inverter board not processing motor position after surge
Step-by-step fixes
- 1Unplug and try rotating the drum by hand—it should turn with belt resistance
- 2Remove the rear access panel on electric models and confirm the belt is on the pulley
- 3Power off five minutes, then start Air Fluff without heat
- 4Listen for brief motor attempt—3C with no drum movement confirms drive fault
When to call a technician
Belt intact with 3C every start needs drive motor, hall sensor, or inverter board service.
Affected models
- Samsung DVE45R6300V
- Samsung DV42H5000EW
- Samsung DVE50R5400V
Prevention & maintenance
- Clean drain filters and hose terminations monthly on high-use dryers to prevent 3C from lint and food debris buildup.
- Record when 3C appears in the cycle and whether it clears after a 60-second power reset on your Samsung dryer—that detail speeds diagnosis if you call service.
- Keep the model and serial number from the rating plate when ordering parts for 3C; Samsung uses multiple revisions with different harness lengths and board firmware.
- Photograph wiring connector orientation before disconnecting any component while troubleshooting 3C; reversed plugs on pumps and valves cause immediate repeat faults.
