Step-by-step troubleshooting
Check Load Balance
Do: Open the washer and redistribute the laundry evenly.
Observe: Is the load balanced and centered?
Means: An unbalanced load can cause shaking.
Next: If balanced, proceed to the next step. If not, redistribute and restart the cycle.
Level the Washer
Do: Place a level on the washer's surface and adjust the feet until it's level.
Observe: Is the washer level on all sides?
Means: An unlevel washer can vibrate excessively.
Next: If level, proceed to the next step. If not, adjust the feet and restart.
Secure the Washer
Do: Ensure the washer is on a stable, flat surface and tighten any loose feet or bolts.
Observe: Is the washer stable and not moving?
Means: Loose feet or an unstable surface can cause shaking.
Next: If stable, proceed to the next step. If not, secure the washer and restart.
Inspect Suspension System
Do: Check the shock absorbers or springs for wear or damage.
Observe: Are the suspension components intact and functioning?
Means: Worn suspension parts can lead to excessive vibration.
Next: If damaged, replace the parts. If not, proceed to the next step.
Check Drum Bearings
Do: Listen for grinding noises and feel for excessive movement in the drum.
Observe: Are there unusual noises or movement?
Means: Worn drum bearings can cause shaking and noise.
Next: If issues are found, contact a professional. If not, proceed to the next step.
Verify Proper Installation
Do: Ensure the washer is installed correctly and all components are secure.
Observe: Is the washer installed according to the manufacturer's guidelines?
Means: Improper installation can lead to operational issues.
Next: If installed correctly, the issue may require professional attention.
Common causes table
| Cause | Why | Likelihood | Difficulty | Part often needed |
|---|---|---|---|---|
| Unbalanced Load | Unevenly distributed laundry causes vibration. | High | Low | No |
| Unlevel Washer | A tilted machine vibrates more during spin cycles. | High | Low | No |
| Worn Suspension Components | Damaged shocks or springs fail to absorb vibration. | Medium | Medium | Yes |
| Loose or Broken Drum Bearings | Worn bearings create excessive movement and noise. | Medium | High | Yes |
| Improper Installation | Incorrect setup leads to instability during operation. | Low | Medium | No |
| Damaged Feet or Pads | Worn or broken feet cause the washer to rock. | Medium | Low | Yes |
Parts matching
If you need to replace parts, match these specifications:
- Shock absorber: model number and length
- Drum bearings: diameter and compatibility with your washer model
- Feet or pads: original part number and size
- Suspension springs: tension rating and length
Always refer to your washer's manual for exact part specifications.

When to call a pro
- If the washer continues to shake after checking all basic fixes

- If you suspect internal component failure like a broken transmission
- If the washer is under warranty and you don't want to risk voiding it
FAQ
Why does my washer shake only during the spin cycle?
The spin cycle generates the most force, so any imbalance or instability becomes more noticeable during this phase.
Can I use anti-vibration pads to fix the shaking?
Anti-vibration pads can help if the washer is slightly unlevel, but they won't fix underlying issues like worn suspension or unbalanced loads.
How do I know if the drum bearings are bad?
Bad drum bearings often produce a grinding noise and may cause the washer to vibrate excessively, even with a balanced load.
Is it safe to continue using a shaking washer?
It's generally safe if the shaking is minor, but prolonged use can cause further damage. Stop using it if the shaking worsens or if there are unusual noises.
Can a full load cause a washer to shake?
Yes, an overloaded washer can cause imbalance and shaking. Always follow the manufacturer's load capacity guidelines.
