MAPIWhy Is My Washing Machine Shaking During the Spin Cycle?
A washing machine reaches its highest drum speed during spin, so imbalance and installation problems become much more visible then than during filling or gentle tumbling.
If your washer shakes during spin, check the load and installation before assuming a mechanical failure. LG identifies unbalanced loads, leveling problems, and shipping bolts or packing material left in place as major vibration causes.
Key takeaways
- Unbalanced or bulky loads can make the tub rotate unevenly.
- A washer that is not stable and level can rock more as spin speed increases.
- Shipping bolts or packing material left on a newly installed front-loader can cause severe vibration and noise.
- Persistent vibration after load and installation checks may need service.
What it actually means
Spin-cycle vibration is movement of the washer cabinet caused by forces generated as the drum accelerates and rotates at high speed.
The main explanation
LG's current vibration guidance prioritizes three checks: the load itself, whether the washer is stable and level, and whether shipping hardware was removed. These checks are especially important on recently installed front-load machines because shipping bolts are designed to lock the tub for transportation, not operation.
Main causes and reasons
1. The load is unbalanced
Single heavy items, tangled loads, or bulky items can concentrate weight on one side of the drum.
How to recognize it
- Shaking changes from load to load
- A blanket or single heavy item is inside
- Washer repeatedly redistributes the load
Why it matters: LG lists unbalanced and mixed heavy/light loads as vibration causes.
2. The washer is not level or stable
Uneven feet or a weak floor can allow the cabinet to rock as the drum spins.
How to recognize it
- One corner rocks when pressed
- Feet do not contact the floor evenly
- Vibration decreases after leveling
Why it matters: LG says washers are designed for a stable level floor and includes leveling in vibration troubleshooting.
3. Shipping bolts or packing material remain installed
Shipping hardware locks the tub for transport and must be removed before normal use.
How to recognize it
- Washer was recently installed
- Bolts remain on the rear panel
- Severe vibration occurs even with a light load
Why it matters: LG warns that leaving shipping bolts or retainers installed can cause severe vibration, noise, and permanent damage.
4. A service-level problem remains after basic checks
If the load, floor, leveling, and shipping hardware are correct, another fault may need diagnosis.
How to recognize it
- Vibration occurs with small balanced loads
- Cabinet is stable and level
- Problem persists after installation checks
Why it matters: Manufacturer support should take over when basic installation checks do not resolve the problem.
How to identify your situation
Load balance is the likely cause.
Next: Redistribute the load and use the appropriate cycle.
Leveling or floor contact is likely contributing.
Next: Adjust feet exactly as the manufacturer directs and tighten lock nuts if required.
Shipping hardware is a direct cause.
Next: Do not continue normal operation until all specified shipping hardware is removed.
A service-level issue is more plausible.
Next: Contact manufacturer support.
What you can do
- Pause and redistribute an obviously unbalanced load.
- Check that every washer foot contacts a stable floor.
- Level the washer using the manufacturer's procedure.
- Verify all shipping bolts and packing materials were removed on a new installation.
- Run a light test load after corrections.
- Request service if excessive vibration persists.
Common misconceptions
Load balance and installation conditions commonly cause excessive vibration.
LG states the opposite: they are transportation hardware and can cause severe vibration and damage if left installed.
When it may be a bigger problem
Stop using a newly installed washer if shipping hardware is still attached. If excessive vibration continues after the load, floor, leveling, and shipping materials are correct, contact the manufacturer for service.
Frequently asked questions
Can an unbalanced load make a washer shake?
Yes. LG lists unbalanced, bulky, tangled, and mismatched loads among common vibration causes.
Can an unlevel washer shake during spin?
Yes. LG includes leveling and stable floor contact in its vibration troubleshooting.
Can shipping bolts cause severe vibration?
Yes. LG warns that shipping bolts or retainers left in place can cause severe vibration, noise, and permanent damage.
What if the washer still shakes after leveling?
Test with a light balanced load and confirm shipping materials are removed; if vibration persists, request service.
