Question about LG LDF6810 Built-in Dishwasher
My LG LDF6810 is making a loud "TRRRRR" noise during operation. This noise is not there when the pump is running. After a while the machine stops with the LE error code. I suspect a mechanical interferance problem causing the motor to lock up. I "think" I smelled some sort of a burning or "electronic" heat related smell but am not 100% positive.
Any ideas? Where can I down load a service manual from? How about schematics?
This seems to be a very common problem withe these dishwashers. The LE error code (locked engine) is not allways indicative of a motor problem. I had the same issue with my diswasher (3 months out of warranty). I found out that one of the gray wires which runs the length of the door panel was pinched and broken simply from the repetative motoin of opening and closing the door over time (very poor design). Good news is that it was an easy fix. Simply unscrew the front door panel from the retaining screws on the inside of the perimiter 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 thouroghly. 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 and you're back in buisiness!

The broken wires, on older models prior to Mar 07, is due to the black insulation getting tacky and then the wires adhering to them. The wires may break in time. The thin gray wires are actually for the water sensor, if they were broken the symptom would be the unit drains then fills for 20 seconds and comes up with a E1 code. The wires for the main wash motor are purple and black.
The noise you may have heard could be caused from siphoning. If your unit has a siphoning problem it will be trying to wash with very little water. When you hear this noise, open the door and see what the water level is. If it is below the 2nd rim then you need to redo your drain hose and make sure is has a loop or a air break.

In my LG, there were 6 broken wires in the door! I would find one wire that was broken, and in moving it around to get at it, another wire would disintegrate! I cannot see how this was caused by vibration. All the wires were cut at the same level, just above the plastic shield at the bottom of the door. This is a manufacturing defect. How this appliance ever got UL / CSA approval is beyond me!

Have owned LDF6810 for 2-1/2 yrs when LE error code occured. Thanks to this website and all you folks who posted your fixes, we took off the front panel. Didn't have any pinched wires, but cleaned corroded ground connection, and it's back operating for now. Will post again if have any more issues. Like the rest of you, am very disappointed in this crappy dishwasher. The only thing good about it is that it's quiet.

I was getting the same LE Code and we read here on this site about the wires and the black insulation problem. We opened it up and sure enough the wires were stuck like glue into this black mess. We freed the wires and ran the dishwasher without the door cover on and it ran fine. We also read about the suggestion of encasing the wires into a bike tube and we did that. Thanks for all your great suggestions. I would like to be able to find a manual for other repairs in case I have future problems. Where do I find one, along with a wiring detail for this machine.

I too, after reading the internet posts found the purple wire stuck in the black insulation was broken. Our unit is 4 years old. Soldered it together, heat shrink tubing, and cased all the wires in a plastic flexible wire carrier. Running smooth as silk again. Easy, no cost fix. Poor design, though.
Make sure you check all the wires carefully before you drop a bunch of money, time, and effort on a sump assembly.
Thanks for all the good advice on here.

You can't do anything about the long run times. However, I found that the dirty dishes after completion relates to the relatively lower temperature the dishwasher runs at (i think why the long run times). A LOT of greasy gunk (technical term for gross stuff) builds up under the screen and within the pump area. That eventually starts making the cleaning water very dirty. A thorough cleaning by disassembling the mechanism inside the tub works wonders.

CHECK THE WIRES. Go slow and check each one of them. I didnt find this site until after I spent $250 in parts and washed dishes by hand for a few weeks. It was a blue wire stuck in the black goo. Thank you to those that posted before me. I wish i would have read this BEFORE replacing parts!

I had the LE error code as well after four years of use. I unscrewed the plastic cover on the bottom of the inside of the dishwasher revealing the plastic impeller. After attempting to turn it, it did not spin freely. I ordered a new motor, part M060. I removed the screw (turning clockwise), removed the impeller, the plastic section below that, and the metal impeller on the motor shaft. Once the motor shaft was revealed, I turned the dishwasher on its side and removed the bottom metal cover revealing the underside of the motor. There were magnetic shards around the outside of the motor. I removedt the three ground wires, and unclipped the wiring harness. I installed the replacement motor I bought, part M060, and installed the three ground wires, wiring harness, and four screws. I replaced the metal cover on the bottom and put the dishwasher back on its base. I replaced the metal impeller, the plastic section, the plastic impeller, and the top plastic section. I downloaded a service manual from the internet to ensure that I put everything back in the correct order on the inside as well. The dishwasher works now.
