Open the door and remove all items. Shake each one out individually to loosen them, then reload loosely one item at a time, placing items evenly around the drum. Avoid bundling items together — pack them in a loose, single layer.

A single large absorbent item — a duvet, a heavy bath mat, a thick jumper — absorbs water unevenly and creates a significant weight imbalance. Wash bulky items with 2 or 3 smaller items to counterbalance them, or use the LG Bedding programme which uses a slower dedicated spin for large items.

Use a spirit level on top of the machine and check in both directions. Adjust all four feet — turn anti-clockwise to raise, clockwise to lower — until the machine is stable with no rocking at any corner. Tighten each locking nut firmly against the base once level.

If the machine was recently installed, check that all transit bolts have been removed from the rear panel. These yellow or red bolts lock the drum for transport. A machine with transit bolts in place will vibrate violently and display UE on every spin cycle.

If the machine is on a smooth tiled or laminate floor, vibration during spin can cause it to walk and rock. Place anti-vibration pads under all four feet to eliminate movement.

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