Samsung Washer UB Error Code

Load is unbalanced. What it means, which models show it, and how to clear it, easiest fix first.

SamsungAll Samsung washer codes

UB
Easy DIY fix

The washer cannot spin because the clothes have bunched to one side of the drum. This is common with a single heavy item, a very small load, or tangled sheets and blankets. If the code shows up even with well-spread loads, the washer may not be level or a suspension part may be worn.

Compatible models

Samsung doesn't publish a model list for this code; it appears on Samsung washers with a digital display. Check your owner's manual.

Also shown as

Also shown as Ub, UE, U6, 1 Ub, or 1U6. Some models show lowercase dc for an unbalanced load, but on other models dc is a door error, so check your manual. Ur means the washer is rebalancing and retrying the spin on its own and is not a fault.

Difficulty

Most people can clear this one at home with simple checks.

Safety first: unplug the washer (or switch off its breaker) before touching filters, hoses or panels. If you smell burning or gas, or see water near the outlet, stop and call a professional.

How to fix Samsung UB

  1. Rearrange the load

    Pause or cancel the cycle and let the door unlock. Untangle the laundry and spread it evenly around the drum, then close the door and press Start.

  2. Fix the load size

    A tiny load can bunch up on one side of the drum, so add a few similar items or choose a lower spin speed. Wash bulky items like comforters on their own or with a couple of towels. Skip items Samsung warns against, such as floor mats, pillows, and pet beds.

  3. Level the washer

    Unplug the washer first. Push on each top corner; the cabinet should sit firmly with no rocking. On front-load models, loosen the lock nuts on the feet, turn each foot to adjust height, and retighten the nuts. Leave about an inch of space around the cabinet, then plug it back in and run a small test load.

When to call a technician

If the code keeps appearing with balanced loads on a level washer, or the tub bangs loudly during spin, the shock absorbers, suspension rods, or springs may be worn and a technician should inspect them. Your manual may also describe a Calibration mode to run with the drum empty; if the tub will not spin during calibration, request service.
