A Samsung washer UB error means the washer cannot balance the load well enough to complete the spin. Samsung may also display UE on some models. The fix is often simple, but repeated codes with normal loads can point to installation or suspension problems.
Why the UB code appears
- A single heavy item is sitting on one side of the tub.
- The load is too small, too large, or tangled.
- The washer is not level or the floor flexes.
- Shipping hardware was not removed from a newly installed front loader.
- Suspension, dampers, tub components, or sensors need service.
Safe checks to clear UB
1. Let the washer stop
Pause the cycle and wait until the basket is completely still and the lid or door unlocks. Never defeat the lock or reach into a moving washer.
2. Redistribute the load
Untangle items and spread them evenly. A wet comforter, bath mat, or small load containing one heavy garment may need one or two similar items to balance it. Follow the model’s capacity guidance.
3. Remove excess laundry
If the tub is tightly packed, remove several items. Clothes need room to move. Wash waterproof or bulky items only on a cycle the owner’s manual permits.
4. Check leveling
With the washer off, press gently on opposite top corners. It should not rock. Confirm all feet contact a solid floor and follow Samsung’s leveling instructions. Do not crawl under or tilt a full washer.
5. Consider installation issues
For a new front-load installation, verify the shipping bolts were removed exactly as directed. Do not operate the washer with shipping hardware installed.
When to call a professional
Schedule service if UB occurs with every normal load, the empty basket sits off-center, the washer bangs violently, leaks, or walks despite correct leveling. Stop using it if the tub appears loose or the cabinet is damaged.

Frequently asked questions
Is UB the same as UE on a Samsung washer?
Both generally identify an unbalanced-load condition, although displays and model instructions vary.
Why does the washer add time after UB?
It may redistribute the load and try the spin again, which extends the estimated time.
Can one blanket cause UB?
Yes. One saturated bulky item can collect on one side of the tub.
Should I keep restarting the spin cycle?
No. Rebalance the load first. Repeated violent attempts can damage the appliance or nearby surfaces.
