A washing machine that vibrates, shakes, or moves during operation can be caused by an installation issue, uneven load, worn suspension components, or damaged internal parts. Some vibration during high-speed spin cycles is normal, but excessive shaking can cause loud noises, movement across the floor, and potential damage to the washer.

A washer may vibrate because it is not level, overloaded, unbalanced, or because components such as shock absorbers, suspension rods, leveling legs, or bearings have worn out.

Below are the most common causes of a washing machine that is vibrating or shaking and the recommended solutions.

1. Washer Is Not Level

Most Common Solution

Why It Causes Vibration Problems

A washing machine must sit level on a solid surface to operate correctly. If one or more feet are not properly adjusted, the washer can rock during the spin cycle and create excessive vibration.

Common symptoms include:

• Washer moves across the floor
• Loud banging during spin cycle
• Machine rocks when pushed
• Uneven gaps between washer feet and floor

How to Level a Washing Machine

1. Disconnect power to the washing machine.
2. Check that the washer is placed on a solid, flat surface.
3. Place a level on top of the washer.
4. Adjust the leveling feet until the washer is balanced.
5. Tighten the locking nuts on the feet.
6. Push the washer gently to confirm it does not rock.
7. Run a test spin cycle.

2. Unbalanced Washer Load

Why It Causes Vibration Problems

An uneven distribution of clothing inside the washer can cause the drum to become unbalanced during the spin cycle. Heavy items such as blankets, towels, and rugs can collect on one side and create excessive movement.

Common causes:

• Too many heavy items in one load
• Washing a single large item
• Clothes gathered on one side of the drum
• Overloaded washer

Solution:

1. Pause the washer cycle.
2. Open the washer door or lid.
3. Redistribute clothing evenly.
4. Remove some items if the washer is overloaded.
5. Restart the spin cycle.

3. Washing Machine Shock Absorbers

Why It Causes Vibration Problems

Front-load washing machines use shock absorbers to stabilize the drum during spinning. Over time, shocks can wear out and lose their ability to control movement.

Common symptoms include:

• Washer shakes violently during spin
• Loud banging noises
• Drum moves excessively when pushed
• Washer walks across the floor

If the shock absorbers are damaged, they should be replaced.

How to Replace Washing Machine Shock Absorbers

1. Disconnect power to the washer.
2. Turn off water supply.
3. Remove the front, rear, or bottom access panel.
4. Locate the shock absorbers supporting the drum.
5. Remove mounting pins or bolts.
6. Remove damaged shock absorbers.
7. Install replacement shock absorbers.
8. Secure mounting hardware.
9. Reassemble panels.
10. Test washer operation.

4. Washing Machine Suspension Rods

Why It Causes Vibration Problems

Top-load washing machines use suspension rods to support and balance the wash tub. If the rods become worn, stretched, or damaged, the tub can move excessively during spin cycles.

Symptoms include:

• Tub hits the washer cabinet
• Loud banging sounds
• Washer shakes during spin
• Tub does not return to position properly

How to Replace Washer Suspension Rods

1. Disconnect power to the washer.
2. Remove the washer top panel if required.
3. Locate the suspension rods supporting the tub.
4. Remove damaged rods.
5. Install replacement suspension rods.
6. Confirm the tub is properly supported.
7. Reassemble the washer.
8. Run a test cycle.

5. Washing Machine Suspension Springs

Why It Causes Vibration Problems

Suspension springs help hold the wash tub in the correct position. Broken or stretched springs can allow excessive tub movement.

Common symptoms:

• Tub sits unevenly
• Washer shakes during spin
• Loud knocking sounds
• Visible damaged spring

Solution:

1. Disconnect power.
2. Remove access panels.
3. Inspect suspension springs.
4. Replace broken or stretched springs.
5. Check tub balance.
6. Test washer operation.

6. Washing Machine Drive Belt

Why It Causes Vibration Problems

A worn, loose, or damaged drive belt can cause unstable drum movement and vibration during operation.

Symptoms include:

• Squealing sounds
• Drum movement problems
• Burning rubber smell
• Uneven spinning

How to Replace a Washer Drive Belt

1. Disconnect power to the washer.
2. Remove access panels.
3. Locate the drive belt.
4. Remove the damaged belt.
5. Inspect pulleys for wear.
6. Install the replacement belt.
7. Confirm proper tension.
8. Test washer operation.

7. Washing Machine Tub Bearings

Why It Causes Vibration Problems

The tub bearings allow the washer drum to rotate smoothly. When bearings wear out, the drum may become loose and create vibration, noise, or movement.

Common symptoms:

• Loud rumbling during spin
• Drum feels loose
• Excessive shaking
• Water leaking near the bearing area

Solution:

1. Disconnect power.
2. Inspect drum movement.
3. Check for bearing noise.
4. Replace bearings or tub assembly if damaged.
5. Test washer operation.

8. Washing Machine Drive Pulley

Why It Causes Vibration Problems

The drive pulley transfers power from the motor to the washer drum. A loose, cracked, or damaged pulley can cause the drum to spin unevenly.

Symptoms include:

• Shaking during spin cycle
• Clicking or grinding sounds
• Washer does not spin smoothly

How to Replace a Washer Drive Pulley

1. Disconnect power.
2. Remove access panel.
3. Remove damaged pulley.
4. Inspect pulley mounting area.
5. Install replacement pulley.
6. Secure hardware.
7. Test washer operation.

9. Washing Machine Counterweight

Why It Causes Vibration Problems

Many washers use concrete or weighted blocks to stabilize the drum. If a counterweight becomes loose or damaged, the washer may vibrate excessively.

Symptoms include:

• Loud banging sounds
• Sudden shaking during spin
• Movement of the washer cabinet

Solution:

1. Disconnect power.
2. Remove access panels.
3. Inspect counterweight mounting bolts.
4. Tighten loose hardware.
5. Replace damaged counterweight if necessary.

10. Washing Machine Motor or Motor Mount

Why It Causes Vibration Problems

A damaged motor mount or worn motor components can create excessive movement while the washer operates.

Symptoms include:

• Unusual vibration
• Grinding or humming noises
• Washer stops during operation

Solution:

1. Disconnect power.
2. Inspect motor mounting points.
3. Check for loose hardware.
4. Replace damaged motor components.
5. Test washer operation.

11. Washer Shipping Bolts Not Removed

Why It Causes Vibration Problems

New front-load washing machines are shipped with transport bolts that secure the drum during delivery. If these bolts are not removed before installation, the washer may shake violently.

Symptoms include:

• Extreme vibration from the first use
• Loud banging noises
• Washer moves across the floor

Solution:

1. Check the rear of the washer for shipping bolts.
2. Remove all transport bolts.
3. Install the provided caps if included.
4. Run a test cycle.

Preventing Washing Machine Vibration Problems

To help prevent excessive washer vibration:

• Keep the washer properly leveled.
• Avoid overloading the drum.
• Balance heavy laundry loads.
• Remove shipping bolts before installation.
• Replace worn suspension components.
• Place the washer on a solid, stable floor.
