What Does the UB Error Mean?
The Samsung washer UB error code indicates an unbalanced load problem. This means the washer has detected that the laundry inside the drum is unevenly distributed during the spin cycle.
When the load becomes unbalanced, the washer may slow down, stop spinning, or display the UB error code to help prevent excessive vibration or possible damage.
On some Samsung washer models, similar balance-related errors may also appear as UR.
Common Causes of the Samsung UB Error
Several issues can trigger the UB error code, including:
- Unevenly distributed laundry
- Overloaded washer
- Washing a single heavy item
- Washer not level on the floor
- Suspension or balance problems
- Worn shock absorbers
- Excessive vibration during spin cycle
How To Fix Samsung Washer UB Error
Follow these troubleshooting steps to help diagnose and fix the UB error code.
1. Pause the Washer
Stop the current cycle and allow the drum to stop spinning completely.
2. Redistribute the Laundry
Open the washer and evenly distribute the clothing inside the drum.
Avoid:
- washing a single heavy blanket alone
- tightly packed loads
- overloaded wash cycles
3. Remove Excess Items
If the washer is overloaded, remove some clothing and restart the cycle.
4. Check Washer Leveling
Make sure the washer is sitting level on the floor.
An unlevel washer can cause repeated balance problems during spinning.
5. Inspect the Floor Surface
Soft or uneven flooring may increase vibration and trigger the UB error.
6. Restart the Spin Cycle
After redistributing the load:
- close the door
- restart the spin cycle
- monitor for proper operation
How To Reset Samsung Washer After UB Error
You can often reset the washer using these steps:
- Turn off the washer.
- Unplug the washer from power.
- Wait approximately 5 minutes.
- Plug the washer back in.
- Restart the wash or spin cycle.
Some Samsung washer models may use slightly different reset procedures.
