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?

Re: lg dishwasher part unknown
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.

Re: lg dishwasher part unknown
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.

The LG does suffer from "poor quality" motor that causes this type of noise. The main motor and pump assembly is common to give this type of problem. The pump seal leaks a small amount of water that gets onto the front bearing and causes a "grinding = humming" noise. This can be easly replaced once you have the bottom off and dishwasher on its door. The motoe has 1 screw in the back holding the motor to the bottom and two rubber seals for the water pump in/out into the washer. Just pull and move motor and pump assmbly and it comes free. Replace with a new motor and pump assembly...
Check for blockage of the spray arm holes. If they are clear, replace the VIRO motor. It is a small motor next to the main wash motor, which turns a cam, directing water to the bottom, then the top spray arms. (usually, changes position every 2 minutes or so) You will need to remove the dishwasher from the cabinet to replace the VIRO motor.
There is not a reset switch.
First, check to see if there is any obstruction preventing the motor shaft from turning. You will have to remove the lower spary arm and sump cover. The round white impeller should be able to be turned by hand. To remove that, the phillips head screw in the center of it has a left hand thread, so needs to be turned clockwise to remove. Then, you will be able to get further down, to the metal cutter bar which may have a twist tie dental floss wraped around it. If all is fine there, and motor shaft turns by hand, you probably have a bad motor. (permanent magnets in motor can come loose, chip, crack, or the internal Hall sensor can be bad. To replace it, the dishwasher has to be laid on it's side so you can easily change it from the bottom side now.
If you have separated the door panels and confirmed that none of the wiring is embedded in the insulation mastic, your next step is to take the covers off the sump area in the bottom of the dishwasher to see if anything (like dental floss or twist ties) is wrapped around the motor shaft. (note: the cutter blade on the end of the motor shaft is held on with a screw that has a left hand thread) If all was clear, replace the motor. To replace motor, pull dishwasher out of cabinet and lay on its side for easy replacement from this point.
The impeller breaks on the motor shaft. The motor still turns, but the impeller doesn't, so it doesn't pump water. Because the machine senses there is no water pressure from the pump, it shuts down & displays E1 (it thinks there's a water leak, due to no pressure)
Unfortunately the motor/impeller is only available as a complete assembly
As per my email reply chazmano5, the problem is likely to be the water pump/motor assy.
They have a very common fault of the impeller breaking on the motor shaft. The motor still spins, but the impeller doesn't, so there is no water being pumped.
The machine senses there is no water pressure and shuts down, displaying E1 (eg: it thinks no water pressure means there must be a water leak) Unfortunately the motor/impeller is only available as a complete assembly.
I had the same problem with by Kemore Ultrawash after two years. The motor bearing went bad because the seal went out and dish water got to the bearing. If you are handy, this motor comes out after taking the dishwasher out. I was surprised how easily the motor came apart from the dishwasher, a good design. The motor has three screws that holds it together, I took them out and took the motor apart. I took the old beaing off the shaft with a grinder, careful not to groove the motor shaft. I did, but just put some high temp silicone caulk in the groove before I put the new bearing on the shaft. I bought a new bearing on the internet, it is a 22mm x 8mm x 7mm. I bought one that went in a small engine, a quality one. I placed it on the shaft, put the motor back together and put the dishwasher back together. It has run quiet and great for many weeks now. I expect the dishwasher may last many years now, because the bearing I took out was a cheap aftermarket one, and the new one is vastly superior in quality.
Good luck and fire away with any questions. I love this dishwasher and am glad I could fix it for 19$ and some of my time.
the plates and bowels should face into the center of the dishwasher, the spray arm spins at the top and bottom from and sprays outward, check that you are using the soap dispenser and not the rince agent cups, also check to make sure it will spring open , ifall that is good then you may have a bad wax motor or a loose conection. at the wax motor. let me know
