How to fix Ub error code in Samsung washing machines?

The UB error code simply means that the washer is not balanced. Too many clothes in the washer or an uneven distribution of the load can cause this problem. To fix this, open the washer door and redistribute or remove a few clothes so that they are evenly balanced.

What are the causes of Ub errors in Samsung washing machines?

If you see the Ub code on your Samsung washer, it means that the washer has detected an unbalanced load.

The major causes of UB error codes in Samsung washing machines are uneven loading, mixed loading, and overloading.

Even though the UB error code is related to an unbalanced load in most cases and goes away by simply redistributing the load or resetting the washer.

In some cases, there may be a few technicalities that you must be aware of.

Therefore, the causes of Ub error codes are divided into two categories.

• Common Causes
• Rare but possible technical causes

Common Causes

In most cases, the UB error code is not a cause for serious concern and can be fixed by following any of the below solutions.

Here are some common causes that lead to Ub error codes:

Uneven loading

It may happen that the garments have tangled and were unevenly placed inside the washer.

Because of this, the drum gets out of balance, or one of the sensors picks up an unbalanced load.

Mixed load

This is said to be the most common cause of Ub error codes.

If you have a mixture of heavy and light garments in the washer, it may cause an unbalanced load and trigger the Ub Error code.

For instance, you may tend to load a heavy or bulky item along with a lighter pile of laundry. This makes it difficult for the machine to balance the drum.

Overloading

Not respecting the capacity of your washing machine can also lead to Ub error codes.

If you put too many clothes in the washer, they will not be distributed evenly in the drum.

Rare but possible technical Causes

Rarely, the Ub error code can be caused by a manufacturing defect or a technical issue.

In such cases, you will definitely require professional help.

Some of the technical reasons that can cause Ub error codes are given below.

Faulty Shock Absorbers

A faulty shock absorber is another cause of an unbalanced washer.

The job of shock absorbers is to lessen the shaking that happens when the washing machine spins.

So, if they are damaged or not working properly, it can lead to an unbalanced washer, and the Ub error code may show up.

Most front-load washers have multiple shock absorbers located between the outer tub and the base frame of the machine.

So, even if one shock absorber is damaged or not functioning, it can cause the washer to become unbalanced and trigger the Ub error code.

Unbalanced Washer

If your washer is not level, it can also cause the Ub error code to appear.

The washing machine should be level in order to function properly.

If it is not, then it can cause the machine to become unbalanced, leading to the Ub error code.

Check the leveling legs of your washer and make sure they are adjusted properly.

If your washing machine is still not level, you may need to call a technician.

Suspension Springs

Suspension springs help to reduce vibration and also keep the washer level.

If the suspension springs are damaged or not working properly, it can cause the washer to become unbalanced, leading to the Ub error code

In most cases, suspension springs are located either beneath the tub or above the tub.

Over time, suspension springs can become worn out and may need to be replaced.

Problematic Drive Belt

The drive belt transfers power from the washing machine’s motor to the parts of the machine.

In most cases, the drive belt is located between the motor and the drum.

If the drive belt is damaged or not working properly, it can cause the washer to become unbalanced, leading to the Ub error code.

So, if you suspect that the drive belt is causing the problem, then you should call a technician.

Faulty Tachometer

The tachometer is a device that measures the speed of the washing machine’s motor.

If the tachometer malfunctions, it will fail to adjust the speed of the motor. This can cause unevenness and activate the Ub error code.

Problematic Board

The board is the central nervous system of the washing machine.

It is responsible for controlling all the functions of the machine.

If the board is damaged or not working properly, it will not be able to send the right signals to the various components of the machine.

At times, the Ub error code could simply mean a false alarm that got triggered due to a faulty board.

Faulty Bearings

Bearings help to reduce friction and also keep the washing machine’s tub stable.

If the bearings are damaged or not working properly, it can cause excess vibration, making the washer unstable and leading to the Ub error code.

Faulty Motor

A motor that does not run smoothly and freely can cause the washer to share and vibrate, eventually leading to the Ub error code.

Problematic Dampening Straps

If the dampening straps become loose or damaged, the tub will be off balance and trigger the UB error code.

Snubber Ring

If the snubber ring on your top-loading washer fails or becomes excessively worn, it could cause the tub to touch the metal base. This would result in an “Ub” error code.

How to fix Ub error code in Samsung washing machines?

Fixing a UB error code isn’t too hard if the problem isn’t caused by a less common or rare technical issue.

The very first step is to check if the load is distributed in an uneven manner. You can turn off the machine and then open the door for inspection.

Next, carefully remove some garments and place them evenly.

Similarly, you can pull out a few garments that are super heavy and then run the machine.

Moreover, if you have added a mixed load of laundry to the machine, then simply remove the odd ones and see if that helps.

Make sure to run the washer with similar items, such as lighter and bulkier items, separately.

Finally, if none of the above methods work, you can try the following.

• One is to reset the washing machine and then try running the cycle.
• Alternatively, you can turn off the washer for about 30 minutes and try rerunning it.
• Finally, run the washer with a minimum load by selecting a different wash program.

If nothing works out, it’s always best to reach out to a service professional because it could be due to a faulty sensor or a damaged component that supports the drum balance.

Which model is this guide applicable to?

This guide works for almost every Samsung washing machine, including those in the 592 and WF series. For example, model numbers 592-49075, WF340ANRXAC, etc.

Final Thoughts 

Do not force the washer to run with uneven loading or an imbalanced wash drum.

Spread the clothes out evenly or empty a few loads before running it again to fix the problem.

In most cases, UB error codes go away on their own after balancing the load or, in the worst-case scenario, after resetting the washer.

But if you always get a UB error code when you turn on the washer, it means there’s a technical problem and you should definitely call a service technician for help.
