Error Code: Ub Difficulty: Easy
Problem: Alternative display format for unbalanced load error on specific models
How to Fix Ub Error
- Pause cycle and redistribute laundry evenly.
- Reduce load size to maximum 80% drum capacity.
- Ensure machine is level on solid floor (use carpenter’s level on drum).
- Check that shipping bolts were completely removed during installation (4 bolts at rear of drum with plastic caps).
- Inspect drum bearings for excessive play by lifting drum vertically at 12 o’clock position – should have <1/8" movement.
- Test spin cycle empty to verify mechanical balance before reloading.
Samsung Washer UB Checks Before Replacing Parts
- Restart the washer and confirm the UB message returns under the same condition instead of after a one-time interruption.
- Check the simple causes first: load balance, water supply, drain flow, door or lid closure, visible leaks, and power stability.
- Inspect accessible wiring connectors and moisture-prone areas before assuming the control board has failed.
- Use the complete Samsung washer model number from the door, lid, or rear tag before matching any pump, valve, sensor, suspension, lock, or board category.
- If the UB code points to a specific system, test that system directly before ordering replacement parts.
Still Not Working?
If the replacement part didn’t fix the issue, you may have a wiring problem or main board failure.
