LG Washing Machine: excessive vibration
What is this symptom?
Experiencing excessive vibration with your LG washing machine? You may notice it shaking, wobbling, or even 'walking' during cycles, especially on high spin speeds. This issue can stem from shipping bolts still in place, an unbalanced load, or the washer being improperly leveled. Addressing these causes can restore stability and reduce noise during operation.
Important Tips for LG Models
- LG explicitly warns that failing to remove shipping bolts/retainers before first use can cause severe vibration and noise and may lead to permanent damage; LG also notes a shipping foam block/base support may remain and cause vibration.
- LG dampers (shock absorbers) are a common repair for persistent vibration in front-load models; iFixit provides a damper replacement guide written for LG WM3050CW and notes it applies to most LG front-load washers.
Possible Causes
Shipping bolts/retainers (and/or shipping foam block) not removed after installation (front-load models)
How to Identify: Washer is newly installed or recently moved. Extreme shaking/noise from first use. Check rear panel for 4 shipping bolts; check underside/rear for shipping foam block/base support per LG instructions.
Part: Shipping bolts, retainers, shipping foam block/base support (transport packaging)
Washer not level / leveling feet not adjusted correctly / insufficiently rigid floor
How to Identify: Machine rocks when pushed at corners, or bubble level shows it is not level side-to-side/front-to-back. Vibration occurs even with balanced loads. Often worse on flexible wood floors; may improve if moved to more rigid surface.
Part: Leveling feet, cabinet leveling, floor structure
Unbalanced load (clumped items, single heavy item, tangling) or overloading preventing auto-balancing
How to Identify: Vibration occurs mainly with bulky items (blankets, towels or single heavy items; improves when load is redistributed or reduced. Often happens at transition to high-speed spin.
Part: Load distribution in drum/tub
Worn or failed shock absorbers/dampers (front-load) or suspension rods/dampers (top-load)
How to Identify: Washer increasingly vibrates over time even when level and with balanced loads; tub/drum bounces excessively when pushed down by hand; may bang during spin; visual signs of leaking, broken, or loose damper mounts.
Part: Shock absorbers / dampers (front load), suspension system
Counterbalance spring / suspension spring failure or detachment
How to Identify: Tub sits unevenly, tilts to one side, or appears lower than normal; loud banging even after leveling and load redistribution; visible spring damage or disconnection on inspection.
Part: Counterbalance spring(s), suspension springs
Bearing or spider arm (drum support) wear causing instability (more common in older front-load units)
How to Identify: Vibration accompanied by rumbling/grinding noise during spin, visible tub play, or water/oil leakage signs near bearing area; worsens progressively over months. Often persists regardless of leveling or load balance.
Part: Tub bearing, spider arm/drum support
DIY Solutions
Remove shipping bolts/retainers and confirm no shipping block is trapped (new install / recently moved)
- Unplug the washer.
- Move the washer forward to access the rear panel.
- Locate and remove all shipping bolts and retainers from the rear of the washer (typically 4 bolts).
- Install the hole caps provided in the accessory pack to plug the bolt holes.
- Inspect for any shipping foam block/base support that may be trapped beneath or behind the unit and remove it if present.
- Run a rinse-and-spin cycle with a small balanced load to confirm vibration is resolved.
Level the washer and lock the leveling feet
- Place a bubble level on top of the washer (front-to-back and side-to-side).
- Adjust the leveling feet until the washer is perfectly level and does not rock when pressed on corners.
- If your model has lock nuts, tighten them to secure the feet after leveling.
- Re-test with a spin cycle. If vibration persists and the floor is flexible, consider reinforcing the floor or using a rigid base (see next solution).
Correct unbalanced loads (redistribute and avoid single heavy items)
- Pause/stop the washer when excessive shaking begins.
- Open the door/lid (after it unlocks) and redistribute items evenly around the drum.
- If overloaded, remove some items to allow the washer to balance the load.
- Avoid washing single heavy items alone; add a few similar-weight items to balance the load.
- Restart the cycle and monitor during spin.
Stabilize the installation surface (rigid base for flexible floors)
- Confirm the washer is level first.
- If installed on a flexible wood floor and vibration persists, place the washer on a rigid plywood platform sized to fully support all feet (or use a purpose-built anti-vibration base).
- Re-level the washer on the platform and verify no rocking.
- Run a spin cycle to confirm improvement.
Next step
Choose the next step for excessive vibration
Confirm the diagnosis before ordering. An error code can identify the system involved, but it does not prove that a specific part has failed.

When to Call a Professional
Preventive Maintenance
-
Verify washer remains level and feet are firmly planted; re-check after moving the washer or after major vibration events.: Progressive vibration, walking, and cabinet/tub stress
Frequency: Every 6 months or after relocation -
Load laundry in mixed, balanced loads (avoid single heavy items) and do not overload; redistribute items if the washer begins to shake.: Out-of-balance spin events and excessive vibration
Frequency: Every load -
Inspect shock absorbers/dampers and suspension visually if vibration begins to worsen over time.: Severe vibration and secondary damage from worn suspension parts
Frequency: Annually (or when symptoms worsen)
