How to fix it
- Pause, open the door, redistribute the load evenly around the drum, restart.
- If new install: confirm all four rear shipping bolts are out (look for plastic caps in their place).
- Place a bubble level on top of the washer side-to-side and front-to-back; adjust the leveling feet until level.
- Push diagonally on the top corners — the unit should not rock.
- Pull the washer out, remove the top panel, and check the vibration sensor harness on top of the outer tub.
- Run a spin-only test with no load. Still trips = sensor or suspension issue.
- Replace the sensor; if vS persists, inspect suspension struts (typically all four together).
Why it happens
Typical signs: vS, uS, or u5 on the display · Cycle stops during spin · Washer 'walks' across floor · Loud banging during high-speed spin
- Unbalanced load A heavy item like a single bath mat or bedsheet thumps to one side.
- Washer not level Leveling feet loose; one corner unsupported.
- Shipping bolts still installed New install — the four rear shipping bolts must be removed before first use.
- Worn suspension struts or springs Failed shocks let the tub thrash; high-mileage washers.
- Loose or unplugged sensor harness Connector backed off the sensor on the top of the tub.
- Failed vibration sensor Sensor module bad — replace.
