You just need to level the beast. Here is how to stop the shaking and get your laundry room back to peace and quiet.
Key Takeaways
- Check for shipping bolts: If the machine is new and shakes violently, ensure the shipping bolts on the back were removed during installation.
- Use the right tools: A carpenter’s spirit level and an adjustable wrench (or slip-joint pliers) are essential for getting the legs accurate.
- Adjust the legs: Loosen the locking nuts and twist the legs to extend or retract them until the bubble on your level is perfectly centered.
- Stabilize the floor: If the machine is level but still shakes, you may need to reinforce the floor or use a leveling platform.
Signs Your Washing Machine Is Unbalanced
You won’t need a detective to tell you something is wrong. An unbalanced washing machine makes its presence known.
Common signs include:
- Loud banging: Thumping noises during the spin cycle.
- Walking: The machine shifts position or “walks” across the room.
- Visual shaking: The unit vibrates visibly, potentially rattling items off the top.
If you ignore these signs, the excessive vibration can loosen internal hoses, damage the drum bearings, or crack the floor tiles. This often leads to unexpected leaks and expensive repairs down the road.
Why Is My Washer Shaking?
Before you grab your toolbox, it helps to know the culprit.
1. The Shipping Bolts Are Still Attached
This is the most common issue with brand-new installations. Manufacturers install large plastic or metal bolts in the back of the machine to lock the drum in place during transport. If you don’t remove them, the suspension cannot work, and the machine will shake violently.
2. Improper Loading
Washing a single heavy item, like a wet comforter or a pair of jeans, creates a lopsided weight distribution. The drum spins at high speeds, and that single heavy point acts like a wrecking ball.
3. Uneven Legs
Washer legs screw in and out to adjust height. Over time, vibration can cause them to shift, or they may never have been set correctly during installation.
4. Floor Issues
Sometimes the machine is fine, but the house is settling. If your laundry room floor dips or isn’t reinforced, the washer won’t sit flat. This is common in older homes or second-floor laundry rooms.
5. Worn Suspension Components
If your machine is older, the shock absorbers or suspension springs might be shot. When these wear out, they can no longer dampen the movement of the drum.
How to Level a Washing Machine
You can usually fix a wobbly washer in about 15 minutes. You will need a spirit level (bubble level) and a pair of channel-lock pliers or an adjustable wrench.
Step 1: Prep the Machine
Ensure the washer is empty. It is impossible to get an accurate reading with wet clothes weighing down one side of the drum.
Check the legs. Ideally, you want the washer as close to the floor as possible. The lower the center of gravity, the less it will vibrate. If the legs are extended fully, the machine becomes top-heavy.
Step 2: Level Side-to-Side
Place your spirit level across the front top edge of the washer. Look at the bubble; it should sit directly between the two black lines.
- If the bubble leans left: The right side is too high (or left is too low).
- If the bubble leans right: The left side is too high (or right is too low).
To adjust metal legs:
- Locate the locking nut (the nut pressed against the base of the machine) and loosen it by turning it clockwise with your wrench.
- Turn the leg itself. Clockwise shortens the leg; counterclockwise extends it.
- Make small turns until the bubble is centered.
- Once level, retighten the locking nut firmly against the washer base to lock the leg in place.
To adjust plastic legs:
Most plastic legs do not have locking nuts. Simply use your pliers to grip the foot and turn it to raise or lower the corner.
Step 3: Level Front-to-Back
Turn your level so it runs from the front control panel to the back wall. Check both the left and right sides.
For machines with adjustable rear legs:
Repeat the process used on the front legs. You may need a helper to tilt the machine forward so you can reach the back feet. Alternatively, place a 4×4 wood block under the front to prop it up while you work on the back (or vice versa).
For machines with self-leveling rear legs:
Many older units and specific brands have “self-leveling” rear feet. To reset them:
- Tilt the entire washing machine forward carefully until the rear legs lift off the floor (about 3 to 4 inches).
- Gently set the machine back down. The legs should automatically adjust to the floor.
- If they stick, lift the machine again and tap the legs with your wrench to loosen them up.
Step 4: The Shake Test
Once the bubble indicates the machine is level in all directions, do a physical check. Place your hands on opposite corners (front-left and back-right) and try to rock the machine. If there is any movement, adjust the specific leg that is not touching the floor firmly.
Advanced Solutions for Stubborn Shaking
If you have leveled the legs perfectly and the machine still dances, try these solutions.
Install Anti-Vibration Pads
Rubber pads are excellent for dampening noise and gripping the floor. They are particularly helpful on tile or wood floors where plastic feet might slide.
Grab a set of anti-vibration pads. Lift one corner of the machine at a time, slide the pad under the foot, and lower it. Double-check your level afterward, as the pads might have slight thickness variations.
Build a Leveling Platform
If your floor has a severe slope or is structurally soft, a plywood platform can help.
- Cut a piece of 3/4-inch plywood to fit the footprint of your washer and dryer.
- Secure it to the floor joists if possible to add rigidity.
- Place the washer on the plywood and level the feet against this new, flat surface.
Internal Repairs
If the floor is solid and the legs are level, open the machine and check the suspension rods (top loaders) or shock absorbers (front loaders). If these components are greasy, disconnected, or broken, replacing them is the only way to stop the banging.
FAQs
How Do Self-Leveling Washer Legs Work?
Self-leveling legs are designed to slide up and down freely when weight is removed. When you tilt the machine forward, the rear legs drop down. When you set the machine back, friction locks them into the correct position relative to the floor.
How Do You Realign a Washing Machine Drum?
You typically cannot “realign” a drum manually without replacing parts. If the drum looks crooked or bangs against the side, it usually indicates a broken suspension spring, a snapped support rod, or a failed rear bearing.
How Do You Level a Washer In a Tight Space?
This requires patience. Slide the washer out, make a small adjustment to the rear legs based on your best guess, and slide it back in to check. Repeat this process until stable. For the front legs, use a flat wrench that can slip under the machine without needing to tilt it.
Does a Washing Machine Need to Be Perfectly Level?
Yes, it should be as close to perfect as possible. While a tiny variance might not cause immediate disaster, spinning at 1,000+ RPM requires balance. Even a slight tilt can cause premature wear on the motor and bearings over time.
How Much Should a Washer Shake During Spin Cycle?
It is normal for a washer to vibrate slightly as it ramps up speed. However, once it reaches full speed, it should hum smoothly. It should never bounce, bang, or move across the floor.
Can an Unbalanced Washing Machine Cause Damage?
Absolutely. The violent shaking can crack the water tub, ruin the drive shaft, damaging the surrounding cabinetry, and gouge your flooring. It is always cheaper to level the machine than to replace it.
Do I Need to Remove Shipping Bolts?
Yes, removing shipping bolts is critical. These bolts are only there to keep the tub stationary during transport. If you leave them in, the suspension system is locked, and the energy from the spinning drum will transfer directly to the frame and floor, causing violent shaking.
Level It and Forget It
You don’t have to live with a washing machine that sounds like a jet engine taking off. Start by checking your laundry habits and ensuring you aren’t overloading the drum. If that doesn’t work, grab your level and adjust those legs.
Whether you need a quick twist of a wrench or a set of rubber pads to prevent excessive vibrations, leveling your washer extends its lifespan and protects your home.
