Open the door and remove all items. Shake each one out individually to loosen them, then reload loosely one item at a time, alternating small and large items evenly around the drum. A balanced load means weight is distributed as evenly as possible around the circumference.

A single large absorbent item — a duvet insert, a heavy bath mat, a thick jumper, or a pair of jeans washed alone — absorbs water unevenly and creates a significant weight imbalance. Wash bulky single items with 2 or 3 smaller items to help counterbalance them, or use the Samsung Bedding or Delicate programme which uses a dedicated low-speed spin designed for these items.

Use a spirit level on top of the machine and check in both directions. Adjust the four feet — turn anti-clockwise to raise, clockwise to lower — until the machine is stable with no rocking. Tighten each foot's locking nut once level.

If the machine is on a smooth tiled or wooden floor, vibration during spin can cause it to walk and rock. Anti-vibration pads placed under all four feet significantly reduce movement and improve load balance.

If the machine is newly installed, the red or yellow transit bolts at the rear of the machine must be removed before use. These bolts lock the drum for transport and prevent it from moving freely — the machine will UE on every spin cycle with them in place. Check the rear panel for any plastic-capped bolts that were not removed during installation.

Remove a third of the load and restart the spin. If UE clears, the load was simply too large for the drum to balance. Samsung recommends filling the drum to no more than three-quarters of its capacity for spin programmes.
