Samsung Washer - 8C Error Code

MEMS vibration sensor malfunction.

Meaning

MEMS vibration sensor malfunction.

The 8C error indicates that the washer's MEMS (Micro‑Electro‑Mechanical System) vibration sensor is not working properly. Samsung explains that this sensor monitors drum balance, vibration levels, and spin stability. If the sensor fails, sends irregular data, or loses communication with the control board, the washer cannot safely perform high‑speed spins. The system halts operation to prevent excessive vibration, noise, or mechanical damage.

Symptoms

  • Washer stops during spin with 8C displayed
  • Washer vibrates unusually before stopping
  • Spin cycle fails to start
  • Washer repeatedly attempts to rebalance the load
  • Cycle pauses unexpectedly during high‑speed spin

Causes

  • Faulty MEMS vibration sensor
  • Loose wiring harness to the sensor
  • Moisture intrusion near the sensor or PCB
  • Control board communication failure
  • Severe unbalance triggering sensor protection
🔧

Step-by-Step Fixes

  • Restart the washer to reset the sensor.
  • Ensure the washer is level and on a stable floor.
  • Redistribute the laundry load to reduce vibration.
  • Check for excessive moisture around the washer base.
  • If the error persists, the MEMS sensor may require replacement.
⚠️

Safety Notes

  • Unplug the washer before inspecting internal components.
  • Do not continue running the washer if it vibrates violently.
  • Avoid opening the washer during high‑speed spin attempts.
