Samsung Washer Error Code UB: A Troubleshooting Checklist

First: What Does UB Mean?

UB means the washer detected an unbalanced load during the spin cycle and stopped spinning to prevent damage.
This safety feature is common on washers made by Samsung.

Quick Fix Checklist (Start Here)

☐ 1. Pause the Washer

Stop the cycle as soon as the UB code appears.

☐ 2. Open the Drum and Check the Load

Look for:

• Clothes piled on one side

• A single heavy item (towel, blanket, jeans)

Fix: Spread items evenly around the drum.

Load Adjustment Checklist

☐ 3. Is the Washer Overloaded?

• Drum packed too tightly
  Fix: Remove a few items and retry.

☐ 4. Is the Washer Underloaded?

• One heavy item alone
  Fix: Add 1–2 lightweight items to balance the load.

Machine Setup Checklist

☐ 5. Is the Washer Level on the Floor?

• Place a level on top of the machine

• Check left-to-right and front-to-back

Fix: Adjust the leveling feet until balanced and stable.

☐ 6. Is the Washer Rocking or Moving?

• Push gently on each corner
  Fix: Tighten feet so all corners touch the floor firmly.

Restart Checklist

☐ 7. Restart the Spin Cycle

• Close lid or door

• Restart or resume the cycle

• Observe if spinning completes normally

If the cycle finishes, the issue is resolved.

If UB Error Keeps Returning

Move to deeper checks only if the checklist above fails.

☐ 8. Suspension Components (Advanced)

Possible issues:

• Worn suspension rods (top-load models)

• Weak shock absorbers (front-load models)

These parts help stabilize the drum during spinning.

When to Call for Service

Contact a technician if:

• UB error appears on every load

• Washer vibrates excessively even when empty

• You hear knocking or banging sounds during spin

Prevention Checklist (Save This)

• ☐ Do not overload the washer
