Samsung error code Ub: The bubble soak or VRT+ models use 'Ub' to signal an unbalanced drum load that could not be corrected by the machine's automatic redistribution attempts. The spin cycle is paused.

Open the door/lid and manually redistribute clothes evenly around the drum. Heavy items like towels, jeans, and blankets tend to cluster on one side. Mix heavy and light items together.
A single heavy item (like a comforter) cannot be balanced in most residential washers. Either wash it at a laundromat with a larger drum or add a similar-weight item on the opposite side.
Place a spirit level on top of the machine front-to-back and side-to-side. Adjust the leveling feet (usually by turning them clockwise to lower) until the machine is perfectly level. A machine that is off by even 1/4 inch can vibrate severely at spin speed.
Tools needed: Spirit level, Adjustable wrench
Once level, tighten the lock nut on each adjustable foot against the cabinet bottom to prevent the feet from shifting during spin.
Tools needed: Adjustable wrench
A persistent UL/UE error on properly loaded, level machines may indicate worn drum bearings or failed shock absorbers (front-loaders) / suspension rods (top-loaders). Spin the drum by hand — a rumbling or grinding noise confirms worn bearings.
