LG Washing Machine (Front Load) SE error code

Difficulty: Hard · Cost: $50–$150 · Duration: 5m

The SE error appears on LG washing machines and indicates a problem with the motor speed sensor — the component that monitors how fast the drum is spinning during the cycle. Without an accurate speed reading the machine cannot control the spin safely and stops the cycle. A reset resolves it in some cases but if the error keeps returning the motor sensor or its wiring will need to be inspected by a qualified technician.

Common causes

  • Motor speed sensor has malfunctioned or failed
  • Wiring connection to the speed sensor is loose or damaged
  • Temporary electronic glitch causing a false sensor reading
  • Hall sensor fault affecting motor speed detection

How to fix it

  1. 1

    Power off the washing machine and unplug it from the outlet

  2. 2

    Wait 10 seconds then plug it back in

  3. 3

    Power the machine back on and restart the wash cycle

  4. 4

    If SE keeps appearing after resetting contact a technician to inspect the motor speed sensor and wiring
