How to Troubleshoot and Replace a Washing Machine Shock Absorber

If your washing machine is making loud banging noises during the spin cycle, it’s likely that the shock absorbers need attention. These essential components help reduce movement of the washer’s tub, keeping the machine stable, quiet, and functioning properly.

Replacing shock absorbers is usually a simple DIY task that takes about 30 to 60 minutes with the right tools. In this guide, we’ll provide detailed instructions on how to troubleshoot and replace shock absorbers, ensuring your washer works smoothly again.

Key Points:

• Shock absorbers are crucial for reducing washer noise and movement.
• Loud noises and excessive shaking during spin cycles often indicate faulty shock absorbers.
• Replacing shock absorbers is an easy DIY task that typically takes 30 to 60 minutes.
• Always replace both shock absorbers at the same time for even wear and long-term reliability.
• Check other components like springs and straps during the replacement for optimal performance.

What Are Washing Machine Shock Absorbers?

Shock absorbers, located between the washer’s base and outer tub, reduce the movement of the drum during the spin cycle. They play a vital role in absorbing vibrations and stabilizing the machine, preventing excessive noise and potential damage to the washer. Without properly functioning shock absorbers, the washer tub can move freely, leading to banging noises and shaking.

Signs of Faulty Shock Absorbers

Loud Banging Noises During Spin: If you hear loud, banging sounds coming from the washer during the spin cycle, it’s likely due to worn-out shock absorbers. The tub may be hitting the inside of the washer’s cabinet, causing these loud noises.

Excessive Shaking or Vibration: A washer that moves more than usual during operation, especially when spinning, is a sign that the shock absorbers are no longer absorbing the vibrations effectively. Excessive movement can lead to damage to other parts of the washer.

Unstable Loads: When shock absorbers start to fail, the washer can become unstable, making it difficult to handle even moderately unbalanced loads. If you find that your washer constantly shifts or vibrates even with lighter loads, this may indicate worn absorbers.

Tools and Safety Precautions

To replace shock absorbers in your washing machine, you will need the following tools:

• 1/4-inch nut driver
• 5/16-inch nut driver
• Flat-blade screwdriver
• Torx 20 screwdriver
• Small flat-blade screwdriver

Safety Precautions:
Before you begin any repair, it’s crucial to take safety measures:

• Unplug the washing machine from the power source to prevent electrical shocks.
• Shut off the water supply to avoid leaks.
• Wear safety glasses and gloves to protect yourself from sharp edges and heavy parts.
• Ensure that the washer is stable and, if necessary, get assistance when tilting the machine to access the shock absorbers.

Accessing the Shock Absorbers in Your Washer

1. Disconnect Power and Water: Unplug the washing machine and turn off the water supply. This prevents both electrical hazards and water leaks.
2. Remove the Panels: Depending on your washer model, remove the front or rear panel. Front-load washers typically require the front panel to be removed, while top-load washers may need access through the back.
3. Locate the Shock Absorbers: Once the panel is removed, locate the shock absorbers, which are positioned between the base and the outer tub. Most front-load washers have two to four shock absorbers.

How to Replace Washing Machine Shock Absorbers

Inspecting the Shock Absorbers

Look for signs of damage, such as broken parts, leaking hydraulic fluid, or weakened resistance when compressing them. Even if only one shock absorber appears to be damaged, it’s best to replace both at the same time to ensure even wear and smooth operation.

Removing the Old Shock Absorbers

1. Locate the fasteners that hold the shock absorbers in place.
2. Use a screwdriver or socket wrench to unscrew the fasteners.
3. Rotate the shock absorber and carefully detach it from the base of the washer.

Installing the New Shock Absorbers

1. Align the new shock absorber with the washer’s base and secure it by rotating it into position.
2. Tighten the fasteners to ensure the shock absorbers are firmly in place.
3. Ensure both absorbers are seated properly and aligned with the washer’s base and tub.

Testing the New Shock Absorbers

After installation, it’s important to test the washer to ensure the new shock absorbers are functioning correctly.

• Run an empty cycle: Start by running the washer without any clothes. Listen for any unusual sounds and check for excessive vibrations during the spin cycle.
• Test with a small load: Add a small load of laundry to further test the stability of the machine. During the spin cycle, observe the movement of the drum. If the tub moves smoothly without loud banging or excessive shaking, the replacement was successful.

Things to look for during testing include:

• Noise levels during the wash and spin cycles.
• Machine stability during operation, especially during spinning.
• Smooth drum movement without sudden jerks or shaking.

Common Mistakes to Avoid

• Replacing Only One Shock Absorber: Even if only one appears damaged, always replace both at the same time. This ensures even wear and helps avoid future problems.
• Improper Installation: Make sure the shock absorbers are properly aligned and fastened securely. Don’t overtighten the fasteners, as this can cause damage to the components.
• Neglecting Other Components: While replacing the shock absorbers, take the time to check other components like suspension springs, snubber rings, and dampening straps. These parts can wear down over time and contribute to washer instability.

Preventive Maintenance for Washing Machine Shock Absorbers

Regular maintenance of your washing machine’s shock absorbers can prevent future problems and extend the life of your washer. Here are a few maintenance tips to follow:

• Inspect Shock Absorbers Regularly: Every few months, check for signs of wear or damage. Replace worn absorbers promptly to avoid further damage to the machine.
• Keep the Washer Level: Ensure your washing machine is placed on a level surface. An uneven washer can cause excessive strain on the shock absorbers, leading to premature wear.
• Avoid Overloading the Washer: Stick to the recommended load capacity for your machine to prevent undue stress on the shock absorbers and other components.
• Clean the Washer Regularly: Clean the drain pump filter and other critical parts to keep your washer running smoothly, which helps reduce strain on the shock absorbers.

When to Call a Professional

While replacing washing machine shock absorbers is generally an easy DIY task, there are instances where it’s best to call a professional. If the machine continues to shake excessively or make noise after the repair, it may indicate a more complex issue. In these cases, professional diagnosis and repair are recommended to avoid further damage.

Most repair professionals can accurately diagnose and fix washing machine issues, ensuring that your appliance is running as smoothly as possible. They can also inspect for any underlying issues that may have caused the shock absorbers to wear out prematurely.
