LG washing machine U5 error code
What U5 means on an LG washing machine
Imbalance or vibration sensor fault.
Meaning checked by NAC's engineers, 9 November 2026.
What our engineers say
On an LG washing machine, the U5 code means the machine has detected a fault with how the load is balanced or with its vibration sensor. You will usually notice it when the machine stops part way through a cycle or refuses to spin.
Engineers sometimes find that the machine has simply been upset by an unbalanced load, where the washing has bunched to one side of the drum. They also sometimes find that the vibration sensor itself needs setting up again so that it reads movement correctly.
An engineer will typically run the machine on a spin with washing inside and press on the drum to check that the parts that cushion its movement have not failed. Where the sensor is the problem, they recalibrate it, then run a spin cycle and a short wash to confirm everything works as it should. They may also offer advice on loading the drum evenly to help stop the code coming back.

Before you check anything yourself
- Switch the washing machine off and unplug it, or turn it off at the isolator switch, before you touch anything. Our guide to safely isolating an appliance walks you through it.
- An error code tells you where to look, not that it's safe to take the washing machine apart. Don't remove panels or covers to get at the parts it points to: that's an engineer's job.
- If it involves the mains supply, sealed parts, or you're not confident at any point, stop and book a qualified engineer rather than risk injury or further damage.
