The laundry load is unbalanced inside the tub.

Ub

What this code can mean

The washer may retry balancing or stop before completing the spin cycle when items are unevenly distributed.

Safe first checks

  1. 1
    Pause the cycle and redistribute tangled or uneven laundry.
  2. 2
    Close the door and restart the cycle.
  3. 3
    Check the model manual because dc can mean a door fault on some models.

Possible causes

  • Laundry is tangled or concentrated on one side of the tub.
  • A bulky item prevents an even distribution.
  • The washer may not be level if the problem repeats across normal loads.
Stop conditions
  • Stop the cycle if the washer moves excessively or makes impact noises.
  • Request service if ordinary balanced loads repeatedly trigger the code.

Use Samsung spin troubleshooting or an authorized servicer for repeated failures.
