Introduction
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.
What you need
-
Step 1 Reset the washer to clear 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.
-
-
Step 2 Check for a drum obstruction
-
Open the door, and spin the drum by hand to check for abnormal noise or sudden stopping.
-
-
Step 3 Remove the rear access panel
-
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.
-
-
Step 4 Remove the rotor bolt
-
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.
-
-
Step 5 Remove the rotor
-
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.
-
-
Step 6 Inspect the rotor hub and magnets
-
Inspect the rotor hub threads for severe wear.
-
Inspect the rotor magnets for smooth surfaces without wear, cracks, burning, damage, or obstructions.
-
-
Step 7 Remove the stator and disconnect its wiring
-
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.
-
-
Step 8 Inspect the stator for damage
-
Inspect the stator magnet edges and the stator wiring for burn marks or damage.
-
-
Step 9 Remove the rotor position sensor
-
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.
-
-
Step 10 Test the rotor position sensor with a multimeter
-
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.
-
-
Step 11 Install the new rotor position sensor and check harnesses
-
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.
-
-
Step 12 Reinstall the stator
-
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.
-
-
Step 13 Reinstall the rotor and secure the bolt
-
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.
-
-
Step 14 Reinstall the rear panel and test the washer
-
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.
-
Reinstall the rear panel and run a test cycle to confirm the LE code is cleared before returning the washer to service. Repair didn't go as planned? Ask our Answers community for help.
