Fix Washing Machine Violent Shaking
Quick answer
Level the machine using adjustable feet, redistribute or reduce laundry load, and check for loose parts. If shaking continues, inspect the suspension system or call a technician.
Confirm the symptom
- Machine shakes violently during spin cycle
- Excessive noise and vibration during operation
- Leaves marks or slides across the floor
- Wobbles even with small loads
- Shaking stops when load is redistributed
Tools and prep
- Adjustable wrench — To tighten loose bolts or nuts
- Screwdriver set — For removing panels or accessing components
- Tape measure — To check machine leveling
- Rubber floor mats — To stabilize the machine on uneven floors
- Work gloves — For safety when handling parts

Prep & safety
- Unplug the washing machine to prevent electrical hazards.
- Move the machine away from walls or cabinets for access.
- Wear work gloves to protect hands from sharp edges.
Step-by-step troubleshooting
Check Machine Leveling
Do: Use a level to check if the machine is even on all four feet.
Observe: Machine tilts to one side or feet are uneven.
Means: Uneven floor or loose feet.
Next: Adjust the feet using an adjustable wrench to level the machine.
Redistribute Laundry Load
Do: Pause the cycle and redistribute the laundry evenly.
Observe: Shaking stops after redistribution.
Means: Imbalanced load.
Next: Resume the cycle and monitor for shaking.
Inspect for Loose Parts
Do: Check and tighten all visible bolts and nuts on the machine.
Observe: Loose or missing hardware found.
Means: Vibrations from loose components.
Next: Tighten or replace the hardware and test the machine.
Check Suspension System
Do: Look for worn or broken shock absorbers or springs.
Observe: Damaged suspension components.
Means: Suspension failure causing excessive vibration.
Next: Replace the damaged suspension parts.
Verify Proper Installation
Do: Ensure the machine is on a solid, flat surface and not on carpet.
Observe: Machine is on an unstable surface.
Means: Improper installation.
Next: Move the machine to a stable, level floor and secure it.
Test with Empty Load
Do: Run a spin cycle with no laundry.
Observe: Machine still shakes violently.
Means: Internal mechanical issue.
Next: Contact a professional technician for further inspection.
Common causes table
| Cause | Why | Likelihood | Difficulty | Part often needed |
|---|---|---|---|---|
| Uneven floor | Machine not level causes imbalance during spin. | High | Low | Adjustable feet |
| Imbalanced load | Unevenly distributed laundry causes shaking. | High | Low | None |
| Loose hardware | Vibrations from loose bolts or nuts. | Medium | Low | Bolts/nuts |
| Worn suspension | Failed shock absorbers or springs. | Medium | Medium | Suspension kit |
| Damaged drum bearings | Worn bearings cause excessive vibration. | Low | High | Drum bearings |
| Improper installation | Machine not secured on a stable surface. | High | Low | Anti-vibration pads |
Parts matching
When replacing parts, ensure compatibility with your washing machine model.
- Adjustable feet: match the thread size and length to existing feet
- Suspension kit: check model number compatibility
- Bolts/nuts: use same size and type as original hardware
- Anti-vibration pads: measure floor and machine base dimensions
Consult your owner's manual for specific part requirements and installation instructions.

FAQ
Why does my washing machine shake only during the spin cycle?
The spin cycle generates the most force, so any imbalance or mechanical issue becomes more noticeable during this phase.
Can I fix a washing machine that shakes on a carpeted floor?
It's best to place the machine on a solid, level floor. Carpets can amplify vibrations and make shaking worse.
How do I know if the suspension system is damaged?
Look for broken springs, worn shock absorbers, or excessive play in the drum. These signs indicate a faulty suspension system.
Is it safe to continue using a washing machine that shakes violently?
No, continued use can cause further damage to the machine and surrounding area. Address the issue promptly.
