What Does Error Code SE Mean?

Error SE on your LG Washing Machine means: LG Washing Machine error code SE indicates a motor hall sensor error. This occurs when the washing machine's motor control system fails to detect the motor's rotation, causing the machine to malfunction. You may experience issues such as the machine not spinning, making unusual noises, or displaying error code SE on the control panel.

What You'll Need

🔧 Tools

  • Multimeter
  • Phillips
  • Torx T20 screwdriver
  • Wire harness connector release tool

🛒 Parts

  • Motor Hall Sensor

How to Fix Error SE — Step by Step

  1. 1

    Step 1: Power Cycle the Washing Machine

    First, unplug the washing machine from the power outlet to reset the system. Wait for at least 30 minutes before plugging it back in. This will clear any temporary faults and may resolve the issue. Make sure to check the machine's power cord and outlet for any signs of damage or wear.

  2. 2

    Step 2: Check the Motor Hall Sensor Connection

    Locate the motor hall sensor connector on the washing machine's control board. Use a wire harness connector release tool to carefully release the connector. Inspect the connector and surrounding area for any signs of damage, corrosion, or loose connections. Make sure all wires are securely connected and not damaged.

  3. 3

    Step 3: Measure the Motor Hall Sensor Resistance

    Using a multimeter, measure the resistance of the motor hall sensor. The resistance should be around 10-20 ohms. If the reading is significantly different, it may indicate a faulty motor hall sensor. Note the reading and compare it to the manufacturer's specifications.

  4. 4

    Step 4: Inspect the Motor Hall Sensor for Physical Damage

    Carefully inspect the motor hall sensor for any signs of physical damage, such as cracks, dents, or corrosion. If you find any damage, replace the motor hall sensor with a new one. Make sure to follow proper installation procedures to ensure a secure connection.

  5. 5

    Step 5: Replace the Motor Hall Sensor (if necessary)

    If the motor hall sensor is faulty, replace it with a new one. Make sure to purchase the correct replacement part for your LG washing machine model. Follow the manufacturer's installation instructions to ensure a secure connection.

When to Call a Professional

If you'd rather not risk further damage to the appliance, or if the issue persists after trying the above steps, reaching out to a certified technician is your best bet. They can assess the problem and provide a more accurate diagnosis and repair.

Field note: SE is a motor / hall / tach complaint. The control is not seeing rotation, or the rotor cannot start. On LG Washing Machines: remove the load, confirm the drum/basket turns by hand, then check the hall plug at the stator. A foreign object or a seized bearing throws the same code as a failed hall sensor. Drain-filter advice does not apply here.

What this code is not

  • Not a drain-filter or inlet-screen job.
  • Not an unbalance (UE) look-alike if the drum will not turn by hand — that is mechanical bind.
  • A hall sensor that tests good with a seized tub bearing will still throw SE.

Why Your Lg Washing Machine Shows Error SE

LG Washing Machine error code SE is a motor hall sensor error, which occurs when the washing machine’s motor control system fails to detect the motor’s rotation. This can cause the machine to malfunction, resulting in issues such as the machine not spinning, making unusual noises, or displaying error code SE on the control panel. The motor hall sensor is a critical component that monitors the motor’s rotation and sends signals to the control board to adjust the motor speed.
