Quick answer
Shaking in a stackable washer and dryer is often due to an unbalanced load or loose leveling feet. Turn off the unit, redistribute the laundry evenly, and check the feet for stability. If shaking persists, inspect the suspension system and leveling.
Confirm the symptom
- Stackable unit shakes or vibrates during cycles
- Noise increases when shaking occurs
- Unit moves across the floor during operation
- Shaking happens only in certain cycles (e.g., spin)
- Visible wobbling when the unit is running
Tools and prep
- Screwdriver (flathead and Phillips)
- Towel or mat to protect floors
- Owner’s manual for model-specific guidance
- Flashlight for inspecting parts
- Adjustable wrench (if needed for leveling feet)
- Power drill (if replacing parts like suspension springs)
- Safety gloves and goggles
- Turn off power and unplug the unit before inspecting
Step-by-step troubleshooting
- Check Load BalanceDo: Open the washer and redistribute the laundry evenly.Observe: Does the shaking stop or reduce?Means: Unbalanced load is the cause.Next: Continue using the machine if resolved.
- Inspect Leveling FeetDo: Check if the leveling feet are loose or uneven.Observe: Are the feet securely tightened and the unit level?Means: Loose or uneven feet cause instability.Next: Tighten or adjust the feet and test the unit.
- Check Suspension SystemDo: Look for worn or broken suspension springs or shock absorbers.Observe: Are there visible signs of damage or wear?Means: Damaged suspension parts cause excessive vibration.Next: Replace damaged suspension components.
- Verify Stack StabilityDo: Ensure the washer and dryer are securely stacked and locked.Observe: Is there any movement between the units?Means: A loose stack can lead to shaking.Next: Secure the stack using the manufacturer’s recommended method.
- Test on a Flat SurfaceDo: Move the unit to a level floor and test operation.Observe: Does the shaking persist on a flat surface?Means: An uneven floor can cause shaking.Next: Use leveling feet to stabilize the unit or relocate it.
- Inspect Drum BearingsDo: Listen for grinding noises and check for excessive drum play.Observe: Is there unusual noise or movement in the drum?Means: Worn drum bearings can cause vibration.Next: Replace drum bearings if damaged.
- Check for Loose ComponentsDo: Inspect all visible bolts and mounting brackets for tightness.Observe: Are there any loose or missing parts?Means: Loose hardware can lead to instability.Next: Tighten or replace any loose components.
- Test with an Empty LoadDo: Run the washer with no clothes to see if shaking continues.Observe: Does the unit shake without a load?Means: Internal mechanical issues may be present.Next: Further inspection or professional service may be needed.
Common causes
| Cause | Likelihood | Difficulty | Part often needed |
|---|---|---|---|
| Unbalanced Load Clothes clustered unevenly create uneven weight distribution. | Common | Easy | None |
| Loose or Uneven Leveling Feet Improperly adjusted feet prevent the unit from sitting level. | Common | Easy | Leveling feet |
| Worn Suspension System Springs or shock absorbers degrade over time, causing vibration. | Sometimes | Medium | Suspension springs |
| Loose Stack Connection Stacking kit or brackets not properly secured. | Sometimes | Easy | Stacking kit |
| Uneven Floor Floor slope or soft spots cause instability. | Sometimes | Easy | Shims |
| Worn Drum Bearings Bearings allow the drum to rotate smoothly; wear causes vibration. | Rare | Hard | Drum bearings |
| Loose Bolts or Mounting Brackets Vibration from operation can loosen hardware over time. | Sometimes | Easy | Bolts and brackets |
| Internal Mechanical Failure Issues like a damaged motor or transmission can cause shaking. | Rare | Hard | Motor or transmission |
Parts matching
If you need to replace parts, match these common components to your stackable washer and dryer model:
- Leveling feet – Adjust or replace if the unit is not sitting level.
- Suspension springs – Replace if worn or broken to reduce vibration.
- Stacking kit – Secure the washer and dryer together if they move independently.
- Shims – Stabilize the unit on an uneven floor.
- Bolts and brackets – Tighten or replace to ensure all components are secure.
- Drum bearings – Replace if there is grinding noise or excessive drum play.
Always refer to your owner’s manual for the correct parts and installation instructions.
When to call a professional
- Shaking continues after checking all common causes and adjusting the unit.
- You hear loud grinding or knocking noises during operation.
- The unit leaks water or produces excessive heat while shaking.
- You suspect internal mechanical failure (e.g., motor or transmission issues).
- You are unsure about disassembling or replacing internal components.
- The warranty is still valid and covers repair or replacement.
FAQ
Can shaking damage my stackable washer and dryer?
Yes, prolonged shaking can strain internal components and lead to more serious mechanical issues. Address it promptly.
How often should I check the leveling feet?
Check the leveling feet every few months or after moving the unit to ensure stability.
Is it safe to use my washer and dryer if they are shaking?
It is not recommended. Shaking can cause further damage or pose a safety risk. Stop using the unit until the issue is resolved.
Can I use a stacking kit from a different brand?
It is best to use a stacking kit designed for your specific model to ensure compatibility and safety.
Why does my unit shake only during the spin cycle?
This is often due to an unbalanced load or worn suspension components that become more active during high-speed spinning.
How do I know if my drum bearings are worn?
Listen for grinding noises and check for excessive drum play. If present, the bearings likely need replacement.
