UB (and the older UE) on a Samsung washer means "unbalanced" — the machine tried to spin, felt the load thumping to one side, and stopped to protect itself. Most of the time it's the load, and you can clear it in a minute. If it keeps happening on balanced loads, there's a mechanical cause worth checking. Here's the order a tech works it.
A single heavy item (a rug, a comforter) or a light, small load lets everything bunch to one side, so the drum can't spin evenly and trips UB/UE.
Check it: Open the lid, redistribute the load evenly, and add a couple towels to balance a single bulky item or bulk up a tiny load. Restart the spin. This clears most UB/UE codes.
If the machine isn't sitting level and solid, normal loads rock and read as unbalanced.
Check it: Check that all four feet are firmly on the floor and the washer doesn't rock. Adjust the leveling feet and tighten the lock nuts so it sits rock-solid.
A front-load or top-load drum hangs on suspension rods (top-load) or shock absorbers (front-load) that dampen movement. When they wear out, the drum swings too much and trips UB even on good loads — often with loud banging.
Check it: If UB keeps coming back on well-balanced loads and the drum bangs during spin, worn suspension is the likely fix — an affordable, common tech repair.
Less often, a worn drum bearing or a control/sensor fault makes the washer misread balance.
Check it: If suspension checks out, a tech inspects the bearing and the balance sensing.
Usually repair — most UB/UE is free (rebalance the load, level the machine). If it's worn suspension rods or shocks, those are affordable, common parts with flat labor, well below a new washer.

Open the lid and redistribute the load evenly — add a couple towels to balance a single bulky item like a comforter, or to bulk up a tiny load. Restart the spin. Also make sure the washer sits level and solid. That clears the vast majority of UB/UE codes. If it keeps coming back on balanced loads with loud banging, the suspension rods or shock absorbers are worn.
Yes — both mean an unbalanced load. Newer Samsung washers show UB, older ones show UE (or Ub/Ur). Same cause, same fix.
If it's not the load and the machine is level, the suspension (rods on a top-load, shock absorbers on a front-load) has likely worn out, so the drum swings too much during spin. That's an affordable, common repair. Your $50 Quick Check credits toward it.
