Introdução
If your LG (or LG-built Kenmore) washing machine shows the LE error code, makes a grinding or bumping noise, and won’t spin properly, the washer is detecting a motor lock issue. This guide shows how to reset the control, check for physical obstructions, and diagnose and replace the rotor position sensor (RPS), which is a common cause of the LE code.

-
-
Unplug the washing machine, and let it sit for 2–3 minutes.
-
Press and hold the power button for 5–10 seconds while the unit is unplugged.
-
Plug the washing machine back in, and confirm the LE code disappears.
-
Run a cycle to drain any water left in the drum.
-
-
-
Move the washer to access the rear metal panel.
-
Use a Phillips screwdriver to remove the four screws from the rear panel.
-
Slide the rear panel off to expose the motor area.
-
-
-
Use a 17 mm socket wrench to turn the rotor bolt counterclockwise.
-
Hold the rotor in place so it doesn’t turn while you loosen the bolt.
-
Remove the rotor bolt fully once it’s loose.
-
-
-
Pull the rotor straight off the shaft using equal pressure with both hands.
-
Wiggle the rotor gently and evenly on both sides while pulling if needed.
-
-
-
Inspect the rotor hub threads for severe wear.
-
Inspect the rotor magnets for smooth surfaces without wear, cracks, burning, damage, or obstructions.
-
-
-
Use a 10 mm socket wrench to remove the six long screws holding the stator.
-
Hold the stator with one hand, and disconnect the two wire harnesses.
-
-
-
Locate the rotor position sensor on the inside of the stator ring.
-
Use a flat-bladed screwdriver to press in on the sensor’s retaining tab, and remove the sensor from the stator.
-
-
-
Set a multimeter to resistance (ohms).
-
Measure resistance between connector 5 and connector 1, and confirm the reading is 5–15 kΩ.
-
Measure resistance between connector 5 and connector 2, and confirm the reading matches and is 5–15 kΩ.
-
-
-
Snap the new sensor onto the three outer pegs on the stator ring.
-
Snap the sensor onto the inner peg so it locks in place securely.
-
Inspect the stator wiring and harness connectors for frayed wires, damage, or separated connector wires.
-
-
-
Position the stator on the tub, and start two bolts by hand to hold it in place.
-
Thread the two bolts only partway so the stator can’t move.
-
Reconnect the two wire harnesses to the stator.
-
Use a 10 mm socket wrench to install the other four bolts, and fully tighten all six bolts.
-
-
-
Align the rotor hub threads with the tub shaft, and set the rotor onto the stator.
-
Press the rotor toward the tub if needed so the bolt can start threading into the shaft.
-
Apply five or six drops of blue threadlocker to the rotor bolt threads.
-
Use a 17 mm socket wrench to tighten the rotor bolt, then tap the wrench with a hammer a few times to ensure it’s tight.
-
-
-
Slide the rear panel into place.
-
Use a Phillips screwdriver to install the four rear panel screws.
-
Move the washing machine back into place, plug it in, and confirm the hoses are connected.
-
Run a test cycle, and confirm the washer runs smoothly and spins properly without thunking noises.
-
If the LE code returns after replacing the rotor position sensor, re-check the drum for obstructions, inspect the stator and rotor magnets for damage, and inspect the stator wiring harnesses for frayed or broken wires, since the LE code can also be caused by mechanical blockage or electrical faults.
