Samsung Washer Ub Error Code
What it means
Samsung identifies this as an unbalanced-load condition: the laundry is not balanced inside the tub.
Try this first
- Untangle and rearrange the laundry so its weight is more evenly distributed in the tub.
- Close the door and restart the cycle with the Start button.
- If the washer repeatedly cannot complete the spin because of imbalance, use Samsung's washer-will-not-spin guidance.
Can I keep using it?Rebalance the load before continuing the cycle.
Repair usually required?A one-time unbalanced-load code does not by itself indicate a washer hardware failure.
If the error keeps returning
Use the linked official Samsung washing machine error-code article for the manufacturer guidance and model notes.
