Encountering a Samsung washing machine UE error can be frustrating, especially when it interrupts your laundry routine mid-cycle. This specific error code is your appliance’s way of telling you that the laundry load inside the drum is unbalanced, preventing the machine from spinning safely. While modern Samsung washers are designed with smart sensors to protect themselves from damage, understanding how to resolve this issue requires a mix of simple adjustments and, occasionally, mechanical troubleshooting.
Whether you own a sleek front load washer or a high-capacity top load washer, the UE error (sometimes displayed as “Ub” or “E4” on older models) typically points to the same set of problems. This guide will walk you through the diagnostic process, from quick fixes like laundry redistribution to advanced solutions involving calibration modes and suspension components.
What Causes the Samsung Washing Machine UE Error?
The UE error stands for “Unbalanced Error.” During the spin cycle, the wash tub rotates at high speeds to extract water from your clothes. To do this safely, the weight of the wet laundry must be distributed evenly around the drum.
Your washer uses a vibration sensor and motor torque data to detect stability. If the machine senses that the wash tub is wobbling excessively, it will attempt to correct the issue by filling the drum with water and agitating the load to redistribute it. If this automatic attempt fails, the machine stops to prevent damage to the internal components and displays the Samsung washing machine UE error.
Common triggers include:
- Unbalanced load: Washing a single heavy item (like a duvet or jeans) or a load that has tangled into a ball.
- Unlevel machine: The washer is not sitting flat on the floor.
- Mechanical issues: Worn-out suspension rods or shock absorbers.
- Calibration issues: The machine’s weight sensors need resetting.
Immediate Troubleshooting Steps
Before you reach for your toolkit, try these simple operational adjustments. Most UE errors are caused by user error rather than mechanical failure.
Laundry Redistribution
The most frequent cause of the UE error is the laundry itself. If you are washing a mix of heavy and light items, the heavy items can clump on one side of the wash tub during the spin cycle.
- Pause the washer and unlock the door or lid.
- Manually untangle the clothes.
- Spread the items evenly around the drum (for top loaders, arrange them like a doughnut around the agitator or impeller).
- If washing a single heavy item, add a few towels to balance the weight.
- Restart the spin cycle.
Check for Overloading or Underloading
Both extremes can trigger the vibration sensor.

- Overloading: Packing the drum too tightly prevents clothes from moving freely, making it impossible for the machine to balance itself.
- Underloading: A single pair of jeans or one heavy bath mat will slam against the side of the drum. Always try to wash a medium-sized load to ensure smooth operation.
Correcting the Washer’s Physical Setup
If redistributing the laundry doesn’t clear the Samsung washing machine UE error, the problem may lie with how the machine is positioned.
Adjusting Leveling Legs
A washing machine that isn’t level will rock violently during high-speed spins, triggering the error immediately.
- Place a carpenter’s level on top of the washer. Check both front-to-back and side-to-side alignment.
- Locate the leveling legs at the bottom corners of the washer.
- Using a wrench, adjust the legs:
- Turn the legs clockwise to lower the washer.
- Turn them counter-clockwise to raise the washer.
- Ensure the locking nuts are tightened against the base of the washer to prevent the legs from moving over time.
- Press down on opposite corners (front-left and back-right, then front-right and back-left) to ensure there is no “wobble.”
Running Calibration Mode
After leveling your washer, or if you continue to see the error despite a balanced load, you must recalibrate the weight sensors. This is a crucial step that many owners overlook. Calibration mode tells the computer exactly how much the empty drum weighs so it can accurately detect load weight later.

How to run Calibration Mode (General Guide for most Samsung models):
- Remove all laundry from the drum; it must be empty.
- Turn the washer off.
- Hold down two specific buttons simultaneously (Common combinations include Temp + Delay End or Spin + Soil Level) and then press the Power button. The washer should turn on and display “Ub”, “Cb”, or “CL”.
- Press the Start/Pause button.
- The wash tub will rotate back and forth for about 3 minutes.
- When finished, the display will show “0” or “End” and the washer will turn off.
Note: Consult your specific user manual for the exact button combination for your model.
Mechanical Failures and Part Replacement
If you have leveled the machine, balanced the load, run calibration, and still face the Samsung washing machine UE error, you likely have a hardware failure. The specific parts involved depend on whether you have a top load or front load washer.
Top Load Washer: Suspension Rods
In top load washers, the tub hangs from four suspension rods. These rods act as springs to cushion the movement of the tub. Over time, these rods lose their tension or the plastic mounts crack.
Symptoms of bad suspension rods:

- The washer bangs loudly against the sides of the cabinet before showing the UE error.
- You can push the tub down easily with one hand, and it bounces like a pogo stick (it should offer resistance).
- The machine fails to spin even with a perfectly balanced small load.
If these symptoms match, replacing the set of four suspension rods is usually the required fix.
Front Load Washer: Shock Absorbers
Front load washers use shock absorbers attached to the bottom of the drum to manage vibration. If these wear out, the drum will thrash around during the spin cycle.
Symptoms of bad shock absorbers:
- Loud banging noises from the bottom of the machine.
- The washer “walks” or moves across the floor during the spin cycle.
- Oil leaking from the shock absorbers (visible if you remove the back or bottom panel).
The DC Error Code Connection
It is worth noting that on some Samsung models, the DC error code is closely related to the UE error. While DC often indicates a door error (door not closed), it can also signify an unbalanced load on certain top-load models (specifically “dC” vs “dC1”). If your machine fluctuates between UE and DC errors, treat it as an unbalance issue first by checking the suspension rods and leveling.
Summary
The Samsung washing machine UE error is a protective mechanism designed to save your appliance from self-destruction. In 90% of cases, the solution is as simple as untangling a heavy blanket or adjusting the feet of the washer. However, persistent errors often point to the need for a recalibration or the replacement of suspension components. By systematically checking the load, the level, and the calibration, you can often solve the problem without paying for a professional service call.
Frequently Asked Questions
What does the UE error code mean on a Samsung washer?
The UE error stands for “Unbalanced Error.” It is a safety feature that triggers when the machine’s sensors detect that the laundry load is distributed unevenly. This prevents the drum from spinning at high speeds while wobbling, which could damage the internal components.

How can I fix a UE error without calling a technician?
Most UE errors are solved by redistributing the laundry. Pause the machine, open the door, and manually spread the clothes evenly around the drum. If you are washing a single heavy item like a rug or a heavy blanket, add a few towels to help balance the weight. You should also check that the machine is perfectly level on the floor.
What is Calibration Mode and how does it help?
Calibration Mode is a maintenance cycle that resets the washer’s internal weight sensors. By running this mode while the drum is empty, you teach the machine’s computer exactly how much the drum weighs. This allows the sensors to more accurately detect when a load is truly out of balance versus when the sensors are simply misaligned.
How do I know if my suspension rods or shock absorbers are broken?
If your washer bangs loudly against the cabinet, “walks” across the floor, or shows the UE error even with a very small, balanced load, the hardware may be failing. For top loaders, check if the tub bounces like a pogo stick when pushed down; if it does, the suspension rods likely need replacement. For front loaders, check for oil leaks or excessive movement originating from the shock absorbers at the bottom of the drum.
Is there a difference between the UE and DC error codes?
While they are different codes, they can be related depending on your specific model. UE specifically indicates an unbalanced load. The DC (or dC) code typically refers to a door or lid that isn’t closed properly, but on certain Samsung top-load models, the DC code can also signal an unbalance issue. If you see both, start by troubleshooting the balance of the load.
