What vS, uS (Vibration Sensor) Means
vS (sometimes displayed as u5 or uS, since those characters look similar on some panels) indicates a potential issue with the washer's vibration sensor - either a contact problem or an outright sensor malfunction - documented consistently on LG's front-load and top-load washer pages.
Common Causes of vS, uS (Vibration Sensor)
- Vibration sensor contact issue (temporary)
- Vibration sensor itself has failed
- Washer not level, causing genuinely excessive vibration the sensor is correctly flagging
🔧 One Safe Check You Can Try
Press Start/Pause to try resuming; if the error recurs, turn the washer fully off and restart it once before assuming it needs service.
⚠ Why You Shouldn't Go Further Than That
- Before assuming the sensor itself is at fault, check that the washer is properly leveled and not overloaded, since genuinely excessive vibration from an unlevel or overloaded machine can trigger the same code without the sensor being broken.
- If leveling the washer and reducing the load doesn't resolve repeat vS/uS codes, the sensor needs a technician's inspection rather than continued resets.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
