UE on an LG washer means the drum could not be balanced, so the machine gave up on the spin. Clothes come out soaking, and the display tells you to redistribute the load.
Nine times out of ten that advice is right. This page is about the tenth.
UE appears on 9 jobs in our records, across 344 LG washer jobs.
How customers describe it:
"Clothers comes out wet and blinking error code UE, now is making a loud weird humming like loud grinding sound."
"It stopped halfway through, UE on the display screen. I tried to start it again, but all I hear is a grinding noise."
The sound is the whole story
Read those two quotes again. Both customers mention UE and a noise in the same breath.
That combination is the one thing this page exists to tell you: a genuine unbalanced load is quiet. The machine stops, sloshes, tries again, redistributes, and eventually gives up — but it does not grind, hum or growl while it does it.
When UE arrives with a mechanical noise, the machine is not failing to balance your laundry. It is failing to spin at all, and reporting the only thing it can measure.
Here is what that turned out to be on our jobs:
- The spin sensor. On an LG WM3570HWA — a machine we were called back to more than once — the tech's note is one line: "Spin sensor was replaced." The sensor reports drum speed and position to the board. When its signal is wrong, the board reads a drum that will not settle and posts UE, even with a perfectly even load.
- The spider arm. A Kenmore came in with "Drum does not spin and it's making a grinding sound, error message UE." The tech's finding: "Grinding clunky noise in back of drum. Going to be spider drum replacement." The spider is the three-armed casting that holds the drum to the shaft; when it corrodes through, the drum wobbles on its own and nothing you do to the load will fix it.
A worn bearing, a failed spin sensor and a cracked spider all produce the same display. Only one of them is fixed by moving towels around.
When it really is the load
It would be wrong to leave the impression that UE is always serious. On our jobs it sometimes was exactly what it said:
- One customer put a mattress pad cover in on the bulky/large setting. A single large waterlogged item is the classic UE — it holds water on one side of the drum and nothing redistributes it.
- One top-loader, a WT1101CW, came in "not draining and not spinning" with the note "probably unbalanced load."
The rule of thumb: one big heavy item, or a very small load of one or two things, will genuinely throw UE on a machine in perfect health. A normal mixed load that throws UE will not.
UE and LE often arrive together
Two of our nine jobs had both codes. One customer: "It also recently showed different error codes LE and UE even with very minimal loads." Another had the machine "displaying LE error" and UE on the same visit.
That pairing is informative. LE on an LG is a motor-side fault — the hall sensor and its harness, not an overload (we wrote that page from 30 of our own LE jobs). When a machine alternates between LE and UE, the suspicion moves firmly off your laundry and onto the motor, its sensor and the drum it is trying to turn.
One warning from a job that wasn't LG
A Blomberg washer-dryer in our records had shown UE, and the code went away on its own. Later the same machine "started leaking during the cycle and flooded the ground."
A code that clears itself is not always nothing. If UE appeared once and vanished, keep an eye on the floor around the machine for a few weeks.
What you can safely check
- Rebalance and rerun. Open the door, spread the load evenly, close it, and run a spin-only cycle. One big wet item is the single most common cause.
- Check the machine is level. Rock each corner. A front-loader on an uneven kitchen floor, or with its shipping feet never adjusted, will throw UE on loads a level machine handles fine.
- Listen during the spin, with the room quiet. Humming, grinding or a rhythmic knock means stop and call someone. Silence followed by UE means try the load again.
- Spin the drum by hand with the machine off. It should turn freely and quietly, with no scraping and no up-and-down play. Grating, or a drum you can lift at the front, is the spider or the bearing.
- Try a small even load — say four towels. If that spins clean, your machine is fine and the previous load was the problem.
Call a tech when UE comes with noise, when the drum has play in it by hand, or when UE appears on normal loads on a level machine.

Frequently asked questions
What does UE mean on an LG washer? UE means the machine could not balance the drum well enough to spin safely, so it stopped the spin and reported it. It is usually about weight distribution inside the drum, but it is measured indirectly, which is why mechanical faults can produce the same code.
Is UE always an unbalanced load? No. On our jobs the ones that came with a grinding or humming noise were not the load at all: one needed the spin sensor replaced, another needed the drum's spider arm. A genuine unbalanced load is quiet — the machine sloshes and retries rather than grinding.
My LG shows UE and makes a grinding noise — what is it? Treat the noise as the real symptom. Grinding, humming or knocking during the spin points at the drum bearing, the spider arm that holds the drum to the shaft, or the spin sensor that reports drum speed to the control board. Redistributing the load will not help.
Why do I get UE with only one or two items in the washer? Because a very small load, or one large heavy item like a mattress pad or a single duvet, cannot distribute itself around the drum. It sits on one side, the machine detects the imbalance and refuses the spin. This is normal behaviour, not a fault.
My LG shows both LE and UE — is that one problem or two? Usually one. LE on an LG is a motor-side fault rather than an overload, so a machine alternating between LE and UE points at the motor, its hall sensor or the drum it is trying to turn, rather than at your laundry.
Can a washer that isn't level cause UE? Yes, and it is worth checking before anything else. Rock each corner; if the machine moves, adjust the feet. A front-loader that is not sitting flat will throw UE on loads that a level machine spins without complaint.
