Hey guys, I'm new to this forum. I did the broken blue wire fix about 8 months ago and I got the LE error code the other day. I went back into the wires under the front cover to see the blue wire had broken again and it had not, but looking at the other wires I found another wire borken, a white one this time, and still looking further I also found two more wires about to break, a red one and a light blue one. Fixed all three wires and the error code went away.

I agree with the earlier post about a planned failure or bad handling of the wires because all the wires fixed were pushed deep into the tare stuff and none of the others were.

This forum rocks.

Thanks.
Steve

Well I'm brand new to the forum. I too am having trouble with my dishwasher. I haven't quite solved the problem yet but I am determined to get it fixed.

I need some help...... It started yesterday when i had to remove the dishwasher because we are replacing our floors. When i hooked it back up everything went well. However, that night we ran the dishes. During the last 30 minutes of the cycle the it started making a funny noise. Then it shut off and showed the LE code. Luckily, (with deep sarcasm) LG doesn't  list this code in their manual. I have so far rechecked the power source wiring, removed washing blades and rinsers down to the grinder blade, and looked through all the wiring closely by the door. I have reassembled the unit and put it on rinse cycle and it goes for 2 minutes and then prior to the motor turning on it shuts off and gives me the LE code.

Prior to me moving the unit it has been working fine for 3 years. It has always been extremely quiet but takes forever. Not to mention it washes dishes like a 7 year old would.

However, i am out of warranty and need some advice. After reading this post I am going to go back and look even more closely for the broken wires.

Let me know what you think.

Thanks,
Nick

Door wires are always the first place I check, sounds like you are on the right track, if they get embedded in th sound dampening material they will break down towards the bottom of the door.  Seems you have already checked the interior of the sump for something restricting the motor.  The biggest other reason I have seen is a main seal leaking into the motor, you might be able to see it by taking the toe kick off and use a mirror to inspect for water or rust in the base.  That would mean a new sump as the seal is molded into the housing.  If that is the problem, call LG and see what they can do for you...  Never hurts to ask.

PS - start a new thread, everyone else will see it easier. :)

this site was very helpful in diagnosing my dishwasher issue.  Unfortunately I was not one of the lucky ones who just needed to repair the broken wires to resolve the issue.  I did find 3 broken wires(its amazing the dishwasher ran at all before dying).  all three were embedded into the sound proofing and snapped at the base.  I made sure to pull free any wire that was stuck to the door as that is obviously a place the wires are supposed to have some movement when the door is opened. quick note to anyone removing the door cover, place a pillow on the floor(thicker the better) under the door to catch it once you have removed the screws.  also, there is no need to remove the 2 screws closest to the center top where the latch catches, it doesn't hold the door face on.  so after splicing the wires back together, and crossing my fingers, the problem did not go away.  I gave a close listen to the dishwasher as it cycled and after it drained and filled, I could hear the capacitor in the the main control panel attempting to start the motor with no response from the motor.  it sounds like a very high pitch sound, sorta like a disposable camera flash charge.  have your kids give it a listen, they will be more likely to hear it.  after three attempts at starting the motor, the dishwasher gave up and threw up an error.  I inspected the main circuit board so see if anything had fried from the severed wires and noticed the two large capacitor(black and gray cylindrical things) looked swollen, most likely from failure to get that motor started.  $79 later(plus shipping) I had a new motor shipped.  you can double check the motor number if you take off the kickplate on the front and use a flashlight to see the sticker.  you will most likely need to pull the wiring harness clip off temporarily from the motor to see the sticker.  Unfortunately, you do need to remove the dishwasher to get at the motor.  we had to take it outside to dump the residual water, although I suppose I could have sopped up the nasty water with a towel or something.  make sure you start the dishwasher once last time to let it drain whatever it can before starting all of this, just make sure to open the door before it refills again.  once outside, actually replacing the motor was a breeze and took maybe 20 minutes tops.  you have to disassemble the filter and get down to and move the chopper blade.  the impeller does have a left handed thread.  lean the dishwasher over, but beware, the water does not drain OUT of the dishwasher, it will drain INTO the door and soak everything(learned this the hard way....only adding to the issue, I figured I'd take the opportunity to hose the stinky broken thing out...lots of water in the door....lots)  keep the door pretty much closed when you lean it to get the residual water out if there is any.  once you have it empty, lean it on its back(unfinished side) and remove the 2 screws holding the cover plate on.  removing the motor is super simple, 3 screws holding 3 ground wires to the bracket, the wire harness that clips into it, and the 4 screws that actually hold it to the dishwasher. the motor just slips right out, and the new one just pops back in.  re-assemble and reinstall.  the whole process would have taken about an hour, but having to dry out my door insulation and circuitry with a hair dryer before turning the breaker back on added a bit of extra time. its working like a charm now and is much quieter than it has been for years(it was quiet when it was new but started getting a high pitch squeal sometimes when it ran....intermittent).  $90 and an hour verses a new $800 dishwasher and all the time that involves is well worth giving it a shot yourself in my book.  I know LG keeps getting knocked by everyone, but honestly...every appliance I have ever bought has had some sort of issue.  the forums of every brand are full of people saying the exact same thing.  learn to fix it yourself and you'll save yourself money, learn something new, and maybe even surprise yourself that its much easier than you think.

OK, add me to the list of disappointed LG owners.  My DW also came up lame after 5 years with an LE error.  Thanks to all that posted.  I know there has been a good deal of discussion about why the wires are broken.  In my case the purple and grey wires were broken; purple all the way and the grey almost all the way through.  The break was about one third the way up the door, not at the bottom as i thought it would be.  The reason for my breakage was the extra cable, which there was plenty was above the black tar substance; the black tar held the wires in place, causing the bottom sections to tight and then stretched each time the door was opened.  Finally the wire /s broke.  It was due to the black tar, if this was not holding the wires in place this failure would not have happened.  Happy the repair was simple.  Thanks again

Why do yall suppose the black tar is there to begin with? Couldn't a zip tie been just as effective in holding the wires in place?

The black tar is used in the door as insulation against sound.

I'm new to this forum. But the info is excellent.  I have the same LE code issue. Still trouble shooting it though.
After reading I was convinced it must be a wire.  And I peeled the wires out of the black tar/insulation,
but all "look" clean for a 4 year old machine. My question is really a verification that the replacement part,
if necessary, is the motor assembly.

when disassembling down to the grinder I noticed the black gaskets will not reseal.  Does anyone have a part no.

cheers

Wow lots of information on this site.  Thought I would update with my dishwasher.

This morning I saw the LE code.  After reading this thread, I opened the front and checked for wiring, can't find any loose/broken ones.  I put it back and decided to start it up and see what happens.  My dishwasher starts up with draining whatever's in there, then it sprays.  However, when the motor is supposed to start, it is stuck.  I then disassembled the filter assembly and cleaned it up a little.  However, when I try to manually turn the motor, I can't get it past a point with my fingers.  If I use a pair of pliers, it goes through but then would just get stuck on the next revolution.  I placed an order for a new motor from the link in this thread, as well as a gasket since one of them doesn't reseal.  Should get them on Wednesday and I will report back on what happens.

Okay guys.  Got the motor and gasket this morning.  Disconnected the water line and the drain line, took out the dish washer, disassembled the filter assembly, tilted it forward, some water came out, took off the bottom plate held by two screws, disconnected three ground wires, took off the four screws that held the motor, took off the motor and disconnected the harness, put the new motor in, put the filter assembly back in, put the dishwasher back in, connected the water and drain lines, and it starts right up.

It really is very simple.  Good luck to anyone in the future with the LE code!
