LG Washer vS Error — Vibration Sensor Issue Fix

What it means

LG washer vS error (also displayed as 'u5' or 'uS' on some models) means a problem with the vibration sensor — LG's specific 'vibration sensor issue' code.
The sensor that detects unbalanced loads has either lost contact with the control board or is malfunctioning.

Affected Models

  • LG Front Load Washer
  • LG Top Load Washer
  • LG WashTower (combined washer + dryer)
  • LG TurboWash Washer
  • LG TwinWash Washer

Common Causes

  • Vibration sensor connector loose
  • Vibration sensor wiring damaged by years of vibration
  • Sensor itself faulty (broken internally)
  • Sensor bracket detached from the chassis
  • Control board input fault

How to Fix It

  1. Power-cycle the washer.

    Unplug for 60 seconds, plug back in.
    One-off sensor read glitches sometimes clear with a clean reboot.
    If vS returns on the next cycle, the issue is wiring or hardware.

  2. Check the load is balanced.

    Some vS variants are triggered by an extreme imbalance the sensor can't process.
    Open the door, redistribute the laundry evenly around the drum, and try again.
    If vS clears with a balanced load, the sensor is fine — the load was the cause.

  3. Reseat the sensor wiring (technician).

    With the back panel off, find the vibration sensor (usually on the side of the outer tub or near the suspension).
    Push the connector firmly home.
    Check the wiring for damage along its length.

  4. Replace the sensor.

    If reseating doesn't help, the sensor itself has failed.
    Order an LG vibration sensor matching your washer model and replace.
    30-minute job once the back is open.

When to Call a Professional

vS needs the back panel off to access the sensor — a technician job unless you're comfortable opening the washer.
The sensor itself is inexpensive (£15–£30) and a quick swap once accessed.

Frequently Asked Questions

Is LG vS the same as u5 or uS errors?

Yes — same fault, different display formats.
vS, u5, and uS are all LG's vibration sensor error.
Different LG models display it slightly differently depending on the firmware and display type.
Diagnosis and fix are identical: confirm with a balanced load, reseat sensor wiring, replace the sensor if needed.
