Samsung Washing Machine Error Code 8C — MEMS Sensor Error
What this means
Error code 8C indicates a problem with the MEMS sensor, which monitors vibration levels during the spin cycle to detect unbalanced loads. When this sensor fails or loses its connection, the washer cannot properly balance the drum and will halt operation. The issue is typically caused by a faulty sensor, loose wiring, or a control board communication error.
Alternate codes: 8E
Step-by-step fix
4 stepsReset the washing machine
Unplug the washer from the wall outlet and wait 5 minutes. Plug it back in and attempt to run a cycle. A temporary communication glitch between the sensor and control board may clear with a reset.
If the code clears after reset and does not return, monitor over the next few cycles before assuming the issue is resolved.
Locate the MEMS sensor
Remove the top panel of the washer by unscrewing the screws at the rear. The MEMS sensor is a small circuit board typically mounted on top of the inner tub or near the suspension system.
The MEMS sensor is very small — it is often a square circuit board about 1 inch across with a wire harness connector.
Check the sensor wiring
Inspect the wire harness connecting the MEMS sensor to the main control board. Disconnect and reseat the connector at both ends. Look for frayed, pinched, or corroded wires.
Vibration during spin cycles can gradually loosen connectors over time — a firm reseat often resolves the error.
Replace the MEMS sensor if needed
If wiring is intact but the 8C code persists, replace the MEMS sensor (DC93-00278D). Disconnect the old sensor, mount the new one in the same position, and reconnect the harness.
After replacing the sensor, run a spin-only cycle to verify the code has cleared.
When to call a professional
If the 8C code persists after sensor replacement, the main control board may have a faulty sensor input circuit. A technician should diagnose the control board.
