Your LG washing machine's motor is controlled by the main circuit board. This is the brain of your washing machine. Depending on the selected program and which cycle is currently running, the PCB will tell the motor which speed to run at and which direction to turn. The Hall Effect sensor on the main circuit board is fed operational feedback from the motor. If there is any difference between what the motor should be doing and what it is actually doing - the appliance will stop operating and display an "LE" error.
For example: if the main circuit board tells the motor to rotate clockwise at a certain speed and the motor doesn't start, the monitoring sensor will relay this inactivity to the main PCB and a "LE" error will persist. The same error would be displayed if the motor rotates in the wrong direction or runs at the wrong speed. It should be evident there are many faults that could produce the "LE" error code. Failure of one of the major components or a fault in the monitoring and feedback loop, could all lead to this problem. It is true however, some faults occur more regularly than others. Test for the most common causes of failure, eliminate them, and move on to more unlikely faults.
Many causes for the "LE" error are thought to stem from LG's manufacturing process. Many customers found the wiring damaged or completely severed in their washing machine's motor drive and feedback loop. If the wires were installed too close to a moving part, they may be vulnerable to mechanical wear once the machine starts to operate. A washing machine vibrates a lot during a spinning cycle, so it is conceivable wires could be damaged in this way. Check the cables feeding the motor for any obvious signs of damage. If you cannot see any problem, disconnect those wires and check for conductivity with a multi-meter. There should be almost no resistance detected in the wire.
If you find a damaged wire, replace it and ensure the new wire is well out of the way of any moving parts. If the wire is faultless you will have to move on and continue fault finding. Try and turn the motor's rotor by hand, if there is any real friction or if the rotor is seized - you will have to replace the motor. Faultless wiring and a washing machine motor - with the existence of an "LE" error code, indicates a fault in the main system board. It should be noted though; this is unlikely to be the cause of the problem. Almost all "LE" errors indicate faulty wiring - so ensure you have properly checked this before installing a new PCB.

It sounds like the motor sensor has failed and needs to be replaced. Yes a DYI can do it. The sensor is in the back.
Remove the back cover.
Use a 17mm socket to remove the center bolt holding the rotor. Remove the rotor by pulling it straight out. It will be hard but keep pulling.
Now use a 10mm socket to remove the 6 bolts holding the stator assembly. Carefully remove the stator and turn it around to locate two connectors. The 5 wire connector is the motor sensor. Replace it and reinstall and it should work fine.

LE means "Overload in Motor" Unplug the washer, remove clothes, wait 15 minutes for motor to cool down. try again. If problem persists you'll need a certified technician.

Hi,
I had the same error code along with the drum "freezing" up. The first unit that was delivered 2 years ago leaked water from the detergent compartment and they sent a second unit. I have only had this unit for 2 years and I am very disappointed in the LG product. LG
was no help on the phone and I the only people that could service it
were 45min away from were I live. I took the advice of a posting on
this website that it could be a part called the sensor assembly and ordered it from an online electronics store (www.mcminone.com). To get to the sensor assembly, you first unplug and take off the back plate that has 4 small screws. Next, unscrew the big bolt in the middle and take off the hubcap looking part the bolt was securing. Next
unclip the two sets of wires on the bottom of the circle you are
looking at (the set of wires to the right are connected to the sensor
assembly you want to replace). Next you will unscrew the 6 or so smaller bolts to take off the circular piece that the sensor assembly is snapped to. Take it off, unclip the old sensor assembly and clip on the new one – and reassemble. This worked perfectly for me and the part only cost $18 bucks plus shipping. When working, this product works well but I will not be purchasing any LG products in the future.
Hope i helped you.
Thanks for using ' Fixya ' and have a nice day!!

A majority of the time when the LE code appears.. the Hall sensor in the motor is bad. Replacing it. Part # 6501KW2002A from MCM electronics... can help. Good luck.

Hi,
No all you have to do is watch how much and what kind of soap you put in that washer...
