Samsung Washer Error Code 8E — Motor MEMS Sensor Error
What this means
The 8E error code indicates the motor MEMS (Micro-Electro-Mechanical Systems) sensor has failed or is sending erratic readings. This sensor monitors motor vibration and helps the washer detect imbalanced loads and control spin speed. When it malfunctions, the washer may refuse to enter the spin cycle or spin at inconsistent speeds. This code is distinct from 8C (which relates to the vibration sensor for the tub, not the motor).
Alternate codes: 8E1
Step-by-step fix
4 stepsPower cycle the washer
Unplug for 5 minutes, then restart a spin cycle. If the sensor had a temporary glitch, the code should not return.
If the washer starts spinning normally, run a few loads over the next day to verify it does not recur.
Inspect the MEMS sensor connection
Unplug the washer. Access the motor area (bottom of the unit on front-loaders, underneath on top-loaders). The MEMS sensor is a small circuit board typically mounted on or near the stator or motor body. Check its wire connector for looseness or corrosion.
Vibration during normal operation can loosen connectors over time. Reseat the connector firmly.
Test the MEMS sensor
Disconnect the sensor harness. Resistance values vary by model, but typically the sensor circuit shows a measurable resistance (not OL and not 0 ohms). Check the tech sheet for your model's specific expected range.
If the sensor has three wires, it may require specific voltage tests that are beyond basic multimeter troubleshooting — consult the tech sheet.
Replace the MEMS sensor
If the sensor is confirmed faulty, remove it from the motor area and install the replacement. Reconnect the wire harness and run a test cycle.
On some Samsung models the MEMS sensor is part of the stator assembly and cannot be replaced separately.
When to call a professional
If the sensor is integrated into the stator or the motor assembly itself needs replacement, a technician should handle the disassembly.
