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.
