If your LG washer always unbalanced error keeps interrupting your laundry routine, you are not alone. This frustration typically appears as a “UE” or “uE” error code on the display, signaling that the machine cannot distribute the load evenly for the spin cycle. While modern LG washers are designed to correct minor imbalances automatically, persistent issues usually point to specific mechanical failures or setup problems.
This guide covers the most common causes and professional repair steps to resolve the LG washer always unbalanced issue, ensuring your appliance runs smoothly again.

Understanding the UE Error Code and Load Distribution
Before dismantling your machine, it is critical to rule out user error. The “UE” code stands for “Unbalanced Error.”
- Load Distribution: The most frequent culprit is a single heavy item (like a wet towel or rug) or a load that is too small. The washer tub needs a balanced weight to spin effectively.
- Solution: Pause the cycle and redistribute the wet laundry manually. Add a few towels to a small load to create counter-weight.
- Item Type: Avoid washing waterproof items or mats, as they gather water in pockets and create sudden, extreme weight shifts during the spin cycle.
Leveling: The Foundation of Balance
If the machine is not sitting flat, the sensors will constantly detect a phantom imbalance.

- Floor Leveling: Check the floor itself. If the flooring is weak or uneven, the washer will rock. Reinforce the floor if necessary.
- Leveling Legs: Use a bubble level on top of the washer.
- Adjustment: Loosen the locking nut on the leveling legs. Rotate the legs clockwise to lower or counter-clockwise to raise them until the bubble is centered. Tighten the locking nut against the base of the washer to secure the leg.
- Vibration Pads: If your floor is slippery (tile or polished wood), install vibration pads under the feet. These prevent the machine from “walking” and absorb minor tremors that trigger sensors.
Check the Rotor Mounting Nut
In LG direct-drive washers, the drive motor is connected directly to the tub via a rotor.
- The Issue: If the plastic rotor hub cracks or the center mounting nut loosens, the tub will wobble significantly, mimicking an unbalanced load.
- The Fix:
- Unplug the washer and remove the back panel.
- Locate the large center bolt on the rotor (the large metal saucer-like part).
- Ensure this bolt is tight. If the plastic teeth on the rotor are stripped, the rotor must be replaced.
Failed Suspension Rods (Top Loaders)
For top-loading models, the tub hangs from four suspension rods. These act like springs to dampen the movement of the heavy wet clothes.
- Symptoms: If your top-loading LG washer always unbalanced alerts occur alongside the tub banging against the sides of the cabinet, your rods are likely worn out.
- Test: Open the lid and push the tub down hard. It should bounce back up once and stop. If it bounces up and down multiple times like a pogo stick, the rods have failed.
- Replacement:
- Purchase a kit of four new suspension rods.
- Access the top of the cabinet (requires lifting the top deck).
- Replace one rod at a time to keep the tub supported. Apply lithium grease to the top and bottom pivot points to prevent squeaking.
Worn Shock Absorbers (Front Loaders)
Front-loading LG washers use shock absorbers attached to the bottom of the outer tub to manage vibration, similar to a car’s suspension.
- Symptoms: Excessive vibration, loud banging during high-speed spins, and the machine “walking” across the room.
- Diagnosis: Remove the front or rear panel (depending on the model). Inspect the shocks for leaking oil or physical separation. If you can compress a shock absorber easily with one hand, it is defective.
- Repair: Always replace shock absorbers in pairs or a full set of three/four to ensure even dampening.
Faulty Hall Sensor (Rotor Position Sensor)
The hall sensor monitors the position and speed of the drive motor. It is a small electronic part located on the motor stator (the stationary coils behind the rotor).
- The Problem: If this sensor malfunctions, the main control board cannot determine the speed of the drum. It may falsely interpret erratic speed signals as an unbalanced load, triggering the UE error even when the clothes are perfectly balanced.
- Solution: Test the sensor with a multimeter or replace it. It is an inexpensive part and a common point of failure on older LG units.
Broken Spider Arm Assembly
This is the most severe mechanical failure for front-loaders. The spider arm assembly is a three-pronged metal bracket that attaches the stainless steel inner drum to the motor shaft.
- Symptoms:
- A loud “machine gun” noise during the spin cycle.
- The inner metal drum feels loose or “floppy” inside the outer plastic tub when pushed by hand.
- Plastic shavings found in the drain filter or pump.
- The Cause: Galvanic corrosion often eats away at the spider arm metal. When one arm cracks or breaks, the drum spins elliptically, causing violent shaking.
- Repair: This requires a complete teardown of the machine to separate the inner and outer tubs. It is a labor-intensive repair, but necessary if the spider arm is compromised.
Summary Checklist for Troubleshooting
If you are facing the “LG washer always unbalanced” nightmare, follow this order of operations:
- Redistribute Load: Ensure laundry isn’t balled up.
- Level Machine: Adjust leveling legs and check floor leveling.
- Check Suspension/Shocks: Test for “bouncing” (top load) or loose resistance (front load).
- Inspect Motor Area: Tighten rotor nut and test the hall sensor.
- Major Mechanical Check: Inspect for a broken spider arm assembly if the inner drum wobbles independently of the outer tub.
Frequently Asked Questions
What does the “UE” or “uE” error code mean on my LG washer?
The “UE” code stands for “Unbalanced Error.” It indicates that the washer’s sensors have detected an uneven distribution of weight inside the drum, preventing it from reaching high spin speeds. A lowercase “uE” typically means the washer is attempting to redistribute the load itself, while an uppercase “UE” means the machine has failed to balance the load and requires manual intervention.
How can I tell if the suspension rods in my top-loading washer are bad?
You can perform a simple “bounce test.” Open the lid and push the tub down firmly with your hand. A healthy suspension should bounce back to its original position and stop immediately. If the tub continues to bounce up and down multiple times like a pogo stick, the dampening effect of the rods has failed, and they need to be replaced.
Why shouldn’t I wash waterproof items or heavy mats in my LG washer?
Waterproof items, such as rain jackets or rubber-backed mats, trap water in pockets rather than letting it flow through the fabric. During the spin cycle, this trapped water creates a sudden, extreme weight shift that the machine cannot compensate for. This frequently triggers persistent unbalance errors and can even cause the machine to “walk” or vibrate excessively.
What is a spider arm assembly, and how do I know if mine is broken?
The spider arm is a three-pronged metal bracket that connects the motor shaft to the inner drum in front-loading washers. If it breaks due to corrosion, the drum will spin elliptically rather than in a perfect circle. You can diagnose this by checking if the inner metal drum feels “floppy” or loose inside the outer plastic tub, or if you hear a loud, rhythmic banging noise similar to a machine gun during the spin cycle.
