What Causes a Washing Machine to Shake?
When your washing machine rocks, rattles, or shakes violently during a wash or spin cycle, it’s more than just an annoying noise—it’s a sign that something needs attention. A washing machine shaking not only disrupts your home but can also lead to damage to the appliance and your floors if left unchecked. Let’s break down why this happens, what it means for your machine, and—most importantly—how you can fix it.
Common Causes of Washing Machine Shaking
Several practical reasons could be behind your washing machine’s rough moves. Understanding these causes will help you identify solutions quickly.
1. Unbalanced Loads
Most shaking or vibration problems stem from an unbalanced load. If heavy laundry clumps together to one side or mixed items like towels and small shirts aren’t distributed evenly, your washer’s drum becomes off-kilter.
- Large, heavy items (such as blankets, comforters, or rugs) bundled on one side
- Small loads where items stick to the drum
- Mixing absorbent and non-absorbent fabrics together
2. Uneven Machine Placement
A washing machine needs a flat, stable surface. If your machine sits on an uneven floor, or if its adjustable feet aren’t level, it may rock and shake during cycles—especially during the fast spin at the end.
- Sloping or bumpy floors under the machine
- Feet not adjusted properly or locked in place
3. Shipping Bolts Still Installed
Brand new washing machines come with shipping bolts to protect the drum during transport. Failing to remove these bolts after installation can cause extreme shaking. This is a common oversight with new machines.
4. Worn or Damaged Shock Absorbers
Shock absorbers (also called dampers) help stabilize your washing machine’s tub. Over time, these parts can wear out, especially in front-loaders. You may notice more shaking and loud thumping if they need replacing.
5. Broken Suspension Springs or Snubber Ring
- Suspension springs: Keep the drum in place and absorb movement.
- Snubber ring: Helps reduce vibration between the tub and the washer’s base.
When these wear down or break, your washer can become unstable—leading to excessive movement.
6. Faulty or Worn Out Suspension Rods
Top-loading machines have suspension rods that help steady and balance the tub. Damaged rods will cause unbalanced washing and thumping sounds.
7. Overloading or Underloading
Overfilling the drum puts stress on the suspension and can lead to shaking. Oddly enough, washing with too few items can also cause balance problems because the load is not evenly distributed.
Detailed Steps for Diagnosing and Fixing a Shaking Washing Machine
Solving a wobbly washing machine begins with some simple at-home checks. Follow these steps to diagnose and correct the problem.
Step 1: Pause the Wash & Redistribute the Load
- When you hear loud banging or see excessive movement, pause the cycle.
- Open the lid or door.
- Redistribute clothing so it is evenly balanced around the drum.
- Resume the wash to check if the shaking has stopped.
Step 2: Check the Level and Stability Feet
- Use a spirit (bubble) level to check if the washing machine is level.
- Adjust the legs or feet by turning them—usually clockwise or counterclockwise—until the machine sits solidly on the floor.
- Make sure all four feet touch the ground firmly.
- Some washers have locking nuts—secure them in place after adjustments.
Step 3: Clear Out Shipping Bolts (New Machines)
- Locate the shipping bolts at the back of a new washing machine.
- Use a wrench to remove them (refer to your user manual for bolt locations and instructions).
- Plug the holes with the supplied plastic caps.
Step 4: Inspect for Worn or Broken Parts
- Carefully move the machine and examine underneath or behind it.
- Look for loose shock absorbers, broken suspension springs, or worn suspension rods.
- If you spot damage, contact a qualified repair technician or, if you’re handy, order replacement parts compatible with your model.
Step 5: Examine Floor Condition
- Ensure the surface under the washing machine is hard and level.
- Avoid placing washers on soft carpeting, thick linoleum, or mats.
- If your floor is uneven, consider using a plywood base under the machine or placing anti-vibration pads under the feet.
Step 6: Consider Load Size and Wash Settings
- Don’t overload the drum—follow the manufacturer’s recommendations for the maximum load size.
- Similarly, avoid very small loads. If you’re washing single items (like a large blanket), add a few towels to help balance the load.
Step 7: Tighten or Replace Loose Parts
- Washers can develop loose internal screws and bolts. Listen for rattling or knocking sounds.
- Gently rock your washer—if it wobbles or moves easily, re-tighten all accessible screws and bolts.
Benefits of Addressing Washing Machine Shaking Early
Tackling the problem early brings several advantages:
- Less risk of expensive repairs or replacements
- Longer lifespan for your washer
- Quieter operation and more peaceful laundry days
- Reduced risk of water leaks or drum damage
- Protection for floors and surrounding appliances
Challenges in Fixing a Shaking Washing Machine
Some fixes are easy, but a few issues may present challenges:
- Replacing internal parts like shock absorbers, springs, or snubber rings might require disassembling the machine and technical knowledge.
- If your subfloor is weak or a structural issue causes vibration, professional repair might be needed.
- Persistent shaking can sometimes be a sign of a major mechanical problem or a faulty washer design.
If you’re unsure or not comfortable with appliance repair, it’s wise to contact a licensed technician for help.
Practical Tips for Preventing a Shaky Washer
Keep your washer running smoothly with these preventive tips:
- Always distribute laundry evenly before starting the cycle. Take care with heavy blankets or bulky items.
- Wash similar-sized items together. Avoid mixing large and small pieces that can shift.
- Don’t overload or underload your machine.
- Leave some space between your washing machine and the wall (about 1 inch) to avoid contact and noise.
- Regularly check and level your machine’s feet, especially after moving the appliance.
- Add anti-vibration pads under the feet for extra stability.
When to Call a Professional
You may need expert help if:
- You hear loud “thuds” or grinding noises after basic troubleshooting.
- The drum is visibly loose or off its axis.
- Electrical components don’t function or the machine doesn’t power on.
- Removing/replacing internal parts feels too complex or risky.
Summary
A shaking washing machine is common—but it’s not something you have to live with. Most causes, like unbalanced loads or uneven flooring, can be fixed with a little attention and care. Regular maintenance and thoughtful washing habits will keep your appliance running smoothly and quietly for years to come. If shaking persists, don’t hesitate to bring in a professional to protect your home and your washer.
Frequently Asked Questions (FAQs)
1. Why does my washing machine shake only during the spin cycle?
Shaking is most noticeable during the spin cycle because the drum spins at high speed. If the load is unbalanced, the force causes the washer to vibrate or move. Rebalancing the load typically solves this problem.
2. Is it safe to use a washing machine that’s shaking violently?
No. Persistent, violent shaking can cause internal damage to your washer and may even harm your flooring or plumbing. It’s best to diagnose and fix the issue before continuing use.
3. Can I fix washing machine vibration myself, or do I need a technician?
You can handle many causes of vibration—like rebalancing loads, leveling feet, and removing shipping bolts—yourself. However, if you discover broken springs, shock absorbers, or internal parts, or if fixes don’t help, consult a professional.
4. What are anti-vibration pads, and do they really work?
Anti-vibration pads are rubber or foam mats designed to absorb movement and reduce noise. They work well for minor vibration issues or machines on hard floors, but won’t fix serious mechanical problems.
5. My washer is making knocking noises along with shaking. Is something broken?
Knocking sounds with shaking often indicate worn-out or broken suspension components, such as springs or shock absorbers. Inspect your machine and get professional help if you notice anything loose or damaged.
With the right know-how and regular care, you can keep your washing machine stable and save yourself from shaking up your laundry routine!
