The LE error or fault code indicates that the washer motor is either overheating or has lost connection to the motor control circuit board. Turn off the machine for 30 minutes to let the motor cool down. Then, restart the washer. If the code comes back immediately the motor is not likely to be at fault and so you should check the wiring from the motor to the motor control board. Also, check the wiring and condition of the rotor position sensor, also called a HALL sensor. If the code doesn't come back on immediately, but returns after the washer has run for a while, the motor stator may be defective
The LE error on the LG dishwasher means that the dishwasher believes there is a leak because the level of the water is decreasing between the time the wash or rinse cycle begins (with the proper amount of water) and before the cycle ends and the water is pumped out.
After you have ruled out a real leak (check closely underneath) then here is the next step. 99% of the problem with LE is caused by the drain hose not having a high point between where it connects at the dishwasher and the drain.
The fastest (but not best) way to fix this is create a loop in the drain hose raised high up underneath the counter top. Attach it so it will not fall back. The cause of the "leak" is the natural siphon effect that can develop when the drain hose has not high point. (exactly like the siphon tube you may have created in science class.)
Wiring connection is OK? The Impeller of Washing Pump is locked. The rotor of Washing Motor is locked. The Blade is locked.
Remedy:
Check the wiring connection. Replace the cause of restriction. Replace the Washing Motor. Replace the PCB.
LE means locked motor disassemble the filter and work your way down to the macerator(steel chopper blade) remove it and see if the side labeled "this side up" is really up, its in english... dont think the chinese labourers paid attention to the warning cause i have seen alot that were wrong way
You also should remove the door panel and check for a broken wire (usually the blue one)
If all the wiring checks out - it is most likely a broken or locked up impeller.

per instructions in other's posts, I removed door panel, but no wires broken, so called LG and local authorized LG repair and they tell me motor sub-assembly needs replacement, cost $160 for parts, $200 for labor, which is making a new dishwasher look attractive.
LE stands for a locked motor. If the motor has gone it has to be replaced. In some case though, depending on the age of your unit, it could be a broken wire in the door. If you remove your front panel (6 screws) you can have a look, but turn off the power first. Alternatively you can call for a service call.
With the noise, it could also be that your unit has been siphoning and as a result the motor has burnt out. The proper water level for these unit is the water should be up to the second rim on the inside of the cabinet.
