Samsung UB / Ub Error Code

UB on a Samsung washer is an unbalanced-load warning: the drum tried to ramp up to spin speed, sensed the laundry was lopsided, and stopped to protect itself. It's almost never a broken part — redistribute the load and it clears.

UB / Ub / UE

Means: Unbalanced load — the washer detected uneven weight distribution during the spin ramp-up and halted to avoid violent shaking. Older models show UE; newer ones show UB or Ub.

Fix: Pause the cycle, open the door, and spread the laundry evenly around the drum. Add a couple of towels when washing one bulky item, and make sure the machine is level.

What causes a Samsung UB error

UB appears the moment the washer tries to spin and the load sensor reads uneven weight. In order of likelihood:

  • One bulky item: a single comforter, hoodie or bath mat swings to one side and can't balance. The #1 cause.
  • Tangled or clumped laundry: sheets and long items knot together and pile on one side of the drum.
  • Machine not level: if the washer rocks, even a balanced load trips UB. Check all four feet.
  • Too small a load: one or two light items can't spread out enough to balance.
  • Worn suspension / shock absorbers: rare, but if UB appears on normal loads, the drum dampers may be failing.

Step-by-step fix

  1. Pause or stop the cycle and wait for the door to unlock.
  2. Open the door and redistribute the laundry evenly around the drum by hand.
  3. Wash one large item together with two or three smaller items (like towels) so the load can balance.
  4. Check the washer is level: press down on each corner — if it rocks, adjust the leveling feet and tighten the lock nuts.
  5. Close the door and restart on a Spin or Rinse+Spin cycle to confirm UB is gone.

When to call a technician

If UB keeps appearing on normal, well-distributed loads on a level machine, the suspension rods, shock absorbers or the drum bearing may be worn, letting the tub swing too far. That's a service-level repair. For other coded faults, see the full Samsung washer error codes list.

FAQ

What does UB mean on a Samsung washer?

UB (also shown as Ub or UE) means an unbalanced load — the drum couldn't distribute the laundry evenly to spin safely. Redistribute the load and it clears.

Is UB the same as UE on a Samsung washer?

Yes — they report the same unbalanced-load condition. Older Samsung models display UE; newer ones show UB or Ub. The fix is identical.

How do I stop my Samsung washer showing UB every cycle?

Make sure the machine is level, avoid washing a single bulky item alone, and don't overload the drum. If it persists on balanced loads, the suspension or bearing may be worn.
