LG Washer SE Error — Sensor Error Fix

What it means

LG washer SE error means a sensor error — LG's general 'sensor error' code that most often refers to the Hall sensor on the motor.
The control board can't read motor speed correctly, so the wash and spin can't run safely.

Affected Models

  • LG Front Load Washer
  • LG Top Load Washer
  • LG WashTower (combined washer + dryer)
  • LG TurboWash Washer
  • LG TwinWash Washer

Common Causes

  • Hall sensor on motor failed
  • Wiring loose between Hall sensor and control board
  • Connector corroded by water ingress
  • Motor itself faulty
  • Main control board fault

How to Fix It

  1. Power-cycle the washer.

    Unplug for 60 seconds, plug back in.
    One-off sensor glitches sometimes clear on a clean reboot.
    If SE returns on the next cycle, the issue is hardware.

  2. Listen for the motor.

    Start a Spin cycle and listen at the back of the washer.
    The motor should run up to speed.
    Silence means the motor isn't getting power; running but with SE means the Hall sensor isn't reporting back correctly.

  3. Check for water around the motor.

    If you've had a recent leak, water on the Hall sensor or its connector triggers SE.
    Unplug the washer and let it dry for 24 hours.
    If SE clears after drying, water ingress was the cause; fix the leak source so it doesn't recur.

  4. Call a technician.

    If power-cycle and drying don't help, the Hall sensor or motor needs investigation.
    An LG-trained engineer or independent washing-machine technician can diagnose with a multimeter and replace the failing part.

When to Call a Professional

SE involves the motor — a technician job.
Hall sensor replacement is inexpensive (£15–£30 part) but needs the back of the washer opened up to access.

Frequently Asked Questions

Why does my LG washer show SE only when starting the spin cycle?

Because the Hall sensor is mainly used to control motor speed — at low wash and rinse speeds, a marginally-failing sensor still gives a usable signal; at high spin speeds, the higher RPM stresses the sensor and any weakness becomes a clear failure.
If SE appears only at spin and the wash side is fine, the sensor is failing rather than dead — it still reads at low speeds but loses accuracy at high speeds.
Replacement is the fix; the sensor doesn't 'come back' once it starts failing.
