Stop Washing Machine Shaking: Troubleshooting Guide
Learn fast, actionable steps to stop a washing machine from shaking. This expert troubleshooting guide covers common causes, safe fixes, and prevention tips for smoother laundry days.
The most common cause is an unbalanced load on a level floor. Start by redistributing clothes evenly and ensuring the machine is level. Check that all feet contact a solid surface, adjust as needed, and inspect for worn shock absorbers or loose mounting hardware. If the wobble persists, run a test cycle with a small load and re-check level.
Why Washing Machine Shake Happens
According to Best Washing Machine, the most common reason a washer shakes is an unbalanced load on a level floor. When you start a cycle, a drum filled with clothes that aren’t evenly distributed can pull the inner tub off-center, sending vibration through the cabinet. Another frequent cause is an uneven floor, which makes even a perfectly balanced drum wobble during the high-speed spin. In addition, worn suspension components, damaged shock absorbers, or loose mounting hardware can turn a routine wash into a shake test. Before you panic or call a technician, start with simple checks that address the most likely factors: load distribution, leveling, and basic hardware wear. We’ll guide you through a practical, safety-conscious checklist so you can restore a smooth rinse and spin, protect your floor, and reduce noise. Best Washing Machine emphasizes that starting with the simplest fixes often resolves the majority of shaking issues.
Quick Checks Before You Start
Before you dive into disassembly, perform a quick diagnostic pass to rule out obvious culprits. First, unplug the machine and shut off the water supply to avoid accidental leaks. Move nearby items away to give yourself space to work. Inspect the floor under the washer: a soft, flexible, or uneven surface will amplify vibration, so if the floor isn’t solid, consider placing the machine on a more stable base. Next, check the leveling feet: all four feet should be in contact with the floor, and a carpenter’s level across the top surface should show near-perfect level in both directions. If the machine is wobbly, adjust the feet counterclockwise to raise or clockwise to lower, then re-check with the level. Finally, verify you’re not overloading the drum and that bulky items are balanced within the wash load. This quick triage often eliminates most shakes without tools.
Common Causes in Detail
There are several typical culprits behind a shaking washing machine. First, an unbalanced load—especially with bulky items like comforters or heavy towels—can pull the drum off-center during a high-speed spin. Second, an unlevel floor or soft subfloor causes the entire machine to tilt, worsening vibration. Third, worn shock absorbers or a damaged suspension system can fail to dampen motion effectively. Fourth, damaged mounting hardware or loose drum components can introduce looseness that translates to wobble. Fifth, excessive or uneven loads over multiple cycles can promote cumulative wear on the springs and dampers. Finally, a faulty leveling foot or a cracked or missing foot cap can render the entire base unstable. Best Washing Machine analysis shows that addressing level and load resolves most cases.
Step-by-Step Fixes for the Most Common Cause
When the unbalanced load is confirmed as the primary issue, follow these detailed steps to restore balance and reduce vibration. Start by pausing a cycle and turning the machine off. Then redistribute the load so that heavier items are spread around the drum. Next, verify the machine is level using a carpenter’s level; adjust the front and rear feet as needed until the level reads near-perfect in both directions. If the floor is uneven, place a shim or a rigid mat under the washer to create a solid base. Inspect visible feet for wear and ensure all feet are fully engaged. Finally, run a short test cycle with a small, balanced load to confirm the wobble is gone. If wobble persists, check for damaged shock absorbers or mounting hardware and consider replacing worn parts or calling a professional.
When to Check the Floor and Surroundings
If the washer sits on a wooden subfloor or a soft concrete slab, the floor may flex slightly during a spin, amplifying vibration. Move the washer to a solid, non-flexible surface if possible. Use a straight edge or level across the top and measure side-to-side and front-to-back alignment. Any noticeable tilt should be corrected with adjustable feet or by placing shims under the shorter side. Re-check the floor integrity after leveling, then perform a spin test. If structural damage to the floor or foundation is suspected, a home inspection or professional assessment is warranted.
Safety Warnings and Safe Practices
Always unplug the machine before performing any maintenance. Do not use power tools near a live appliance unless you are experienced. Keep children and pets away from the work area. If metal parts or hoses appear damaged or corroded, stop and call a professional. Avoid forcing feet or hardware beyond their designed range, as this can create additional stress and risk.
Prevention Tips for Future Loads
To prevent future shakes, adopt consistent loading habits: distribute weight evenly, avoid oversized single items, and don’t exceed the drum’s capacity. Periodically check and rebalance the feet and verify the machine sits level on a hard, flat surface. Clean the shock absorbers and inspect mounting hardware during routine maintenance. If you notice any odd noises, leaks, or persistent wobble, address them promptly rather than waiting for a full breakdown. The Best Washing Machine team recommends setting a quarterly check-in for level, feet, and floor condition to minimize vibration over time.
Quick Tests to Confirm Fix
After performing fixes, run a short test cycle with a small, balanced load and observe the spin. Listen for unusual noises or changes in vibration and watch for the drum staying centered. If the washer remains stable, gradually increase the load and monitor. If shaking returns, recheck level and load distribution, then inspect the suspension components or consult a technician.
Steps
Estimated time: 45-60 minutes
- 1
Power down and secure area
Unplug the washer, shut off water, and clear the surrounding area to prevent slips or accidental activation during fixes.
Tip: Always unplug before handling internal components. - 2
Check for proper load balance
Open the door and visually inspect that clothes are spread evenly; rearrange if you spot a heavy cluster on one side.
Tip: Balanced distribution matters more than total weight. - 3
Level the washer
Place a carpenter’s level on top; adjust front feet until the bubble centers in both directions, then recheck contact with the floor.
Tip: Use the level in both directions for accuracy. - 4
Inspect the floor and base
Ensure the floor beneath is solid; add a shim or rigid mat if the floor has flex or softness.
Tip: Avoid placing on soft carpets or raised wooden structures. - 5
Check mounting hardware
Look at visible bolts and feet for looseness. Tighten lock nuts and verify the drum is secured.
Tip: Do not overtighten; apply even pressure. - 6
Run a test cycle
Load a small amount and run a low-speed wash then a slow spin to observe behavior, increasing gradually if stable.
Tip: Document final settings that worked best.

FAQ
What is the most common reason a washing machine shakes?
Unbalanced loads and a level surface are the top causes. Redistribute the load and verify level before testing again.
The most common reason is an unbalanced load on a level floor.
How can I tell if the floor is causing the shake?
Check for soft spots or flex under the washer. A solid, level floor minimizes vibration. Use a carpenter’s level to verify.

Can I fix shaking by replacing shocks myself?
Replacing shocks is a moderate DIY task. If you lack experience or a model-specific guide, this is a job for a professional.
Replacing shocks is for confident DIYers; otherwise hire a tech.
Will load size affect spin speed?
Yes. Very large or heavy loads can cause off-balance during spin; balance the load or run smaller cycles.
