Question about LG 24 in. LDS 5811 Built-in Dishwasher
I was thinking about replacing motor on dishwasher and there was a small spring that went over shaft of motor on bottom side. It was bent and worn and was curious if you've seen it and whats it for? I am getting a E1 code and there are no leaks so im assuming its something to do with the motor. The unit fills with water then you hear the motor cycle on a few times before kicking up the E1 code. What do you think?
Yes i guess it is an older model b/c i took of the front panel and saw the tar like stuff that heats up and burns the wires. I covered the wires that were sticky and starting to get stuck to the black mat with some insulating tape. I am now not getting any e1 or 1e errors. I put the high loop on the drain hose which fixed those errors. The motor spins freely by hand and the small spring which came off the shaft was after i took the motor out from the bottom. IT looked like it was just resting on the shaft. Not sure of its purpose or if it was there by mistake. The symptons now are the motor turns on like 3 to 4 cycles before it sounds like it gets enough water to go but then it doesnt really work. It will move the water around b/c i can hear it inside but it sounds like a air / water whirling noise is happening with the motor. Sort of like a low growling noise but it doesnt sound mechanical. Hard to explain, and im not sure if the motor is workign right or if its a water / air problem. Any more advise would be great. I can send you a pic of the spring thing that was on the motor if you want, guess i would need email dont see a way to post the picture here. Thanks for your help i look forard to hearing from you.

If you got this at a garage sale and it has no model / serial sticker on it, it means the customer most likely had several problems with the unit and got it replaced no charge, but the model / serial number had to be sent in "to verify that the product was scrapped". That being said, on to your problem:
IE would be an inlet error, and E1 would be an error code which usually indicates the water has left the tub too early, as if the drain hose did not have a high loop in it, allowing the water to leak out the drain during the wash cycle. The sensor on the motor sees the increased speed of the motor, due to loss of resistance because the impeller spins more freely when in air than water, increased RPM will thus give the E1 error.
So, that may be all it is, but the reason I asked for the serial number is that early production models used an insulating mastic inside the door which became soft and allowed the wiring to become embedded in it. This resulted in the insulation on the wiring dissolving and shorting out or opening up (breaking) some wire(s) inside the door. That would result in various error codes, depending on which wire(s) were affected.
Take the door apart and look to see if the wires are embedded in the insulation. The fix is technically to replace the stainless steel inner door panel with one that has the newer insulation type and replace the entire wiring harness. That's fine if your unit was under warranty, but for you, splice in new wires and put something in the door which will prevent the wires from again becoming embedded in the door's black insulating mastic.
It is unclear to me if the spring you are referring to was found on the very bottom of the motor (as if you look at it from underneath the dishwasher) or if it was found from the inside, when you removed parts and finally got down to the motor. (I assume if that is the case, you discovered that the end of the motor shaft has a left hand thread) I suspect your motor is still fine. Look for the door insulation problem or a break in a wire where the wires pass out the door at the bottom of the door.
I hope with all this info we can get a FixYa out of this problem. It would be nice if you can send a comment to let me know what you found and how things turned out. PS. It is very important to use a rinse aid to get acceptable drying from this dishwasher, and of course you should have soft water.
