Quick answer
A washing machine shaking violently during the spin cycle is usually caused by an unbalanced load or loose components. Check the load balance, ensure the machine is level, and tighten any loose parts to resolve the issue.
Confirm the symptom
- Shaking occurs only during the spin cycle
- Machine moves across the floor during spin
- Loud thumping or rattling noises during spin
Tools and prep
- Screwdriver (flathead and Phillips)
- Towel or rags
- Level
- Owner's manual
- Work gloves
- Turn off power to the washer at the circuit breaker
Step-by-step troubleshooting
- Check Load BalanceDo: Pause the washer and redistribute the laundry evenly.Observe: If shaking stops after redistributing, the load was unbalanced.Means: The laundry was unevenly distributed, causing imbalance during spin.Next: Continue with the cycle if resolved. If shaking continues, proceed to next step.
- Level the WasherDo: Use a level to check the washer's balance. Adjust the leveling legs by turning them clockwise or counterclockwise as needed.Observe: If the washer is now level and shaking stops, improper leveling was the issue.Means: An unlevel washer can cause imbalance during high-speed spin cycles.Next: Test with a new load. If shaking continues, proceed to next step.
- Inspect for Loose PartsDo: Check the washer's feet, transit bolts (if applicable), and internal components for looseness or damage.Observe: If parts are loose or damaged, tightening or replacing them may resolve the shaking.Means: Loose or missing parts can cause instability during the spin cycle.Next: Tighten or replace parts as needed. If shaking continues, proceed to next step.
- Check for OverloadingDo: Reduce the load size to below the washer's maximum capacity.Observe: If shaking stops with a lighter load, the washer was overloaded.Means: Overloading can cause the drum to become unbalanced during spin.Next: Run a test cycle with a smaller load. If shaking continues, proceed to next step.
- Inspect Drum SuspensionDo: Look for worn or broken suspension springs or shock absorbers inside the washer.Observe: If suspension components are damaged, they will need to be replaced.Means: Worn suspension parts can't stabilize the drum during high-speed spins.Next: Replace damaged suspension components. If shaking continues, proceed to next step.
- Check for Foreign ObjectsDo: Inspect the drum and surrounding areas for any foreign objects that might be causing imbalance.Observe: If objects are found and removed, the shaking should stop.Means: Foreign objects can create imbalance and vibration during spin.Next: Run a test cycle. If shaking persists, consider professional repair.
Common causes
| Cause | Likelihood | Difficulty | Part often needed |
|---|---|---|---|
| Unbalanced Load Uneven distribution of laundry causes the drum to spin unevenly. | Common | Easy | None |
| Washer Not Level An unlevel washer can't spin properly, leading to shaking. | Common | Easy | None |
| Loose or Missing Parts Loose feet, bolts, or internal components can cause instability. | Common | Easy–Medium | Leveling feet, transit bolts |
| Overloading Too much laundry can prevent the drum from spinning smoothly. | Common | Easy | None |
| Worn Suspension Components Damaged springs or shock absorbers can't stabilize the drum. | Sometimes | Medium | Suspension springs, shock absorbers |
| Foreign Objects Items like coins or small toys can create imbalance. | Rare | Easy | None |
| Damaged Drum or Motor A bent drum or faulty motor can cause severe shaking. | Rare | Hard | Drum assembly, motor |
Parts matching
If you need parts to fix your shaking washer, here are the most common replacements:
- Leveling feet or adjustable legs
- Transit bolts (if your washer has them)
- Suspension springs or shock absorbers
- Drum support bearings (if applicable)
Always refer to your washer's model number when ordering parts to ensure compatibility.
When to call a professional
- Shaking persists after checking all common causes
- You hear unusual noises like grinding or screeching
- The washer is more than 10 years old and needs major repairs
- You're unsure about performing internal repairs safely
- The drum is visibly bent or damaged
FAQ
Why does my washer shake only during the spin cycle?
The spin cycle spins at high speeds, amplifying any imbalance in the load or machine. This causes shaking that's not noticeable during slower cycles.
Can I use my washer if it's shaking?
It's not recommended to continue using a shaking washer, as it can cause further damage to the machine or your floor. Address the issue before resuming use.
How do I know if my washer is level?
Place a level across the top of the washer. If the bubble is centered, the washer is level. Adjust the leveling legs until it is.
What are transit bolts, and do I need to remove them?
Transit bolts are temporary supports used during shipping. If your washer still has them installed, they must be removed before use to prevent shaking and damage.
Is it normal for my washer to vibrate slightly during spin?
Some vibration is normal, but violent shaking is not. If the shaking is severe, there's likely an issue that needs to be addressed.
