    Default LG WT5001CW UE Code

    Model Number: WT5001CW
    Brand: LG
    Age: 1-5 years

    I've got an LG WT5001CW that keeps throwing a UE code, which is an out-of-balance error... it is clearly not out of balance, resetting the control board will often cure it, I've changed the Out-Of-Balance Sensor and since resetting the control board has been curing the problem when it occurs, I changed the control board but the problem persists. It will do it with or without an empty drum. This almost always occurs at 9 minutes remaining in the cycle. In other words, it has gone through multiple spins to get to this point, successfully, but fails on this final one.

    I'm out of ideas... every other function seems normal. The new control board is a replacement by LG, they have (apparently) obsoleted the original part number, watching the cycle runs, it seems to have some modifications to the software; eg there is a little blue spray head that never did anything before but now it sprays water in the drum during the rinse cycle... that's just an aside, but, all that to say, it fills, agitates and spins fine until the 9 minute mark. It is level, and it ran fine for about a year...

    Hi,

    I found these as well....

    Verify the load is not unbalanced, causing vibration and noise.
    ~ Laundry is unbalanced.

    The pulsator rotates initially, then the inner tub rotates.
    ~ Defective clutch.

    Does the outer tub strike the top cover during a spin cycle when the washer is running empty?
    ~ Yes - One or more of the suspension rods is defective.

    It is very important to determine the cause of any noise or defect in order to repair the problem correctly the first time.

    I don't know much about these machines, hope this helps

    I don't know how to tell if the pulsator rotates initially; I don't even know what it is... all else is fine.

    One things puzzles me about the frame though, the front feet are retracted as far as they will go and still, the front of the washer is very slightly high. It's as if the rear legs are somehow pushed up into the machine. It has a strange, somewhat elaborate, leveling system for the rear legs. However, I took the rear leg assembly apart and it all seems to be as designed, there are no signs of damage or wear.

    The drum spins up to a good speed during the wash cycle, it just fails time and again at the 9 minute mark in the final rinse cycle.

    I thought it well to report back... I am loathe to just throw parts at machines in an effort to diagnose them but that is what I have resorted to in this case. So far I have changed the Overflow Sensor after being led to believe it was an Out-Of-Balance Sensor; The Main Control Board (actually, I was able to try two new boards in it); all four suspension rods and the Hall Sensor. I have checked all of the wiring that I can test and it runs through all of the diagnostics like filling, agitating, locking the lid, draining, bleach dispensing and even spinning perfectly yet it refuses to complete a cycle. Nearly every time it stops it is at 9 minutes to go. At this point it is going on Craig's List and we will never buy another LG washer. The only thing I have not changed in the machine that is related is the Display Board but I read in the Service Manual that the microprocessor is in the Main Control Board so I don't believe it is worth the $150 or so to try it. I've already spent like $250 so far... and I'm done now. This is really disappointing, it is unheard of for me to not be able to fix something mechanical but here I am.

    Thanks Jeff,

    Along that line, what is/are your favorite brand(s)? For cars, I'm sold on Toyota but Hyundai - man, their repair documentation is stellar and free, they're easy to work on, really easy, parts are cheap... Toyota is really tight lipped about Service Repair manual and parts are pretty expensive.

    Any good, easy to work on appliances with good documentation out there? Oh, and for computers, especially laptops, Dell is super for PC, I can tear apart a Dell laptop - all the way to the cooling fan, which is as far as it goes, there's nothing left after that because the heat sink is directly in the microprocessor - in about 10 minutes and only have to remove like maybe a dozen screws. HP - wow, it's at least an hour and a half, maybe 50 fasteners, 15 to 18 really PITA zero insertion force cables and so on...

    Good Engineering makes all the difference, it really does. I found this LG really easy to work on, I wish I could've fixed it.

    I'd like to find a reliable brand but, nothing last forever so, beginning with the end in mind, I'd like to have one that is mechanic AND user friendly.

    -Gary

    Whirlpool ( KitchenAid, Roper, Maytag, Amana ) has probably the most info out there for thier products.
    *I* have no brand preferance.
