  2. Loose motor wiring harness - The 6-pin connector behind the rear access panel may be disconnected
  3. Failed motor control board - The inverter board converts AC to DC for motor operation
  4. Physical obstruction in motor assembly - Debris lodged between stator and rotor
  5. Power supply fluctuations - Voltage drops below 200V during operation
  6. Worn motor brushes - Carbon brushes shorter than 5mm cannot maintain contact ## Troubleshooting Steps | Step | Action | Expected Result | |------|--------|------------------| | 1 | Unplug washer for 3 minutes | System fully resets | | 2 | Inspect rear panel wiring | No loose connectors visible | | 3 | Run diagnostic mode (press Delay End + Soil Level simultaneously) | LED displays “3C” if error persists | | 4 | Check wall outlet voltage | Reads 220-240V during spin cycle | | 5 | Remove rear panel and inspect motor harness | Connector fully seated | If error clears after step 1 but returns during spin cycles, proceed to professional diagnosis. ## When to Call a Technician Contact Samsung-certified repair if:
