Ok if that's the correct code then it will likely be a communication problem between the motor and control panel ie loose wire broken wire resistance on the touch pad control ribbon which can be cleaned with a pencil eraser by the way or something along those lines the control just thinks the motor is bad because it cant communicate with it maybe

TE error code means Thermistor Fault or Inlet Water Temp too High.
Check the resistance of the
thermistor (located on the bottom of the unit in between 2 orange wires
with single spade connectors which is the heating element) and it was
good 11.7K ohms at 71 degrees room temp. Take the front door off and
trace wiring. There is a white plastic wire loom and approx.6" up check
the wiring being melted in the black mastic. The thermistor wiring is red
and dark blue.
Generally, some lose or broken wires cause this. Keep us updated.
IE error usually means the inle valve has failed,However you might want to try a different hose because there is a valve in the lg hoses is you have a grey hose with a chunky bit at the tap end there is a valve inside the hose that often fails.often these guys come back with the motherboard & it doesn't solve the problem.Try ebay for the board they aren't that expensive he has doubled the price of the motherboard anyway.
Well LE means locked motor, this seems to be a very common problem withe these dishwashers.
Possible Cause For Error Occurrence: Wiring connection is OK? The Impeller of Washing Pump is locked. The rotor of Washing Motor is locked. The Blade is locked.
Anyway the LE error code is not all-ways indicative of a motor problem. There are also strong chances of any lose connection (wire), so first you can simply unscrew the front door panel from the retaining screws on the inside of the perimeter of the door. Once the screws are removed pull down and out to remove the door panel. Remove the sound insulating material and you will see several wires routed from the contol panel the length of the door to underneath the unit. Inspect the wires thoroughly. Near the bottom is where the pinching can take place. There are two gray wires and if you have been getting the "LE" error code, one of those wires is most likely broken or pinched. Splice, reconnect, solder or tape.......

The LG error code OE simply means “the pump is blocked”. Presumably the
water isn’t being emptied properly. Check the exit hose, it may be
clogged. LE Code refers to a motor overload.Since the pump is blocked,the motor
becomes inefficient in working.Once you get the pump cleared from
blockages,I assure that you can get rid of these errors.Good luck with
the machine.Please do post the results and comments.
ACCORDING TO SERVICE MANUAL, THE "L.E." ERROR CODE SUGGESTS A LOCKED ROTOR ON THE WASH MOTOR. CHECK THE WASH IMPELLER FOR A FOREIGN OBJECT. IF IT SPINS FREELY, CHECK THE WIRING TO THE WASH MOTOR FOR LOOSE CONNECTION.
THE L.G.HAS HAD A HISTORY OF MOTOR PROBLEMS.
YOU SHOULD BE ABLE TO CANCEL THE PROGRAM AND DRAIN OUT THE WATER.
