Amana Washing Machine Shaking and Vibrating: Causes and DIY Fix Guide
Stop the cycle immediately. An Amana washing machine shaking-vibrating fix usually starts with three quick checks that take less than two minutes: redistribute the load, verify the machine is level, and confirm the shipping bolts are removed. In roughly 70% of cases, one of these actions eliminates the shaking entirely without any tools or parts. Running a severely vibrating machine risks damaging the motor bearings, cracking the plastic tub, or loosening internal wiring—so stopping the cycle is your first safety step.
The Amana Washing Machine Shaking‑Vibrating Fix: First Three Checks
These earliest checks prevent accidental damage and address the most common causes. Perform them in order before moving to any mechanical inspection.
Check 1: Stop the cycle and open the door. Rearrange the wet laundry by hand. A single heavy towel wrapped around a lightweight sheet can create a 10‑pound imbalance at spin speed. Separate tangled items and mix large pieces with small ones. If the load seems unusually small, add a few dry towels—this counter‑intuitive approach helps Amana’s mechanical pressure switch register the load correctly.
Check 2: Place a bubble level on top of the washer. Check front‑to‑back and side‑to‑side. If the bubble is not centered, the machine will vibrate even with a perfectly balanced load. Concrete floors are ideal; wooden subfloors over crawlspaces often flex enough to amplify vibration.
Check 3: Look for shipping bolts on the back panel. If you bought the washer new or recently moved it, plastic or metal bolts may still lock the drum in place. They are usually marked with orange or yellow tags. Remove them with a ½‑inch socket and keep them in a labeled bag for future moves. Running with shipping bolts installed prevents the suspension from working and can damage the drum assembly.
Why the Vibration Happens: A Mechanical Breakdown
Understanding the mechanism behind the shaking helps you diagnose faster and avoid unnecessary part replacements. Amana top‑loaders use a straightforward suspension system: springs hold the drum assembly, and friction pads or struts dampen movement. When any part of this system fails—or when the machine is not properly supported—the drum’s natural oscillation amplifies into the shaking you feel across the room.
Load Imbalance: The Dominant Cause
The washer’s logic board checks for an even load before ramping up to high spin. If clothes clump together around one side, the imbalance sensor (typically a Hall‑effect sensor or pressure switch) triggers a rebalance attempt. The drum rocks back and forth trying to settle the load. If it fails, the cycle either stops or proceeds at reduced speed, but the shaking can still be severe.
Here is the counter‑intuitive angle most generic guides skip: Amana’s load‑size detection uses a simple mechanical pressure switch rather than an electronic weight sensor found on pricier brands like Samsung or LG. This means it can misinterpret a small, wet towel as “fine” when it is actually heavy enough to cause imbalance. Adding a few more items—even dry ones—helps the pressure switch register correctly by providing enough mass for accurate detection. This runs contrary to the common advice to “reduce the load” and is a nuance that saves you from unnecessary troubleshooting.
Uneven Floor or Weak Subfloor
Even if the floor looks level, slight slopes or sagging boards throw off the washer’s feet. Amana washers use self‑leveling rear legs, but the front legs require manual adjustment. If the machine tilts forward or to one side, the drum’s spin axis shifts and vibration intensifies.
Trade‑off analysis: Placing the washer on a concrete slab is ideal. Plywood subfloors over joists can flex enough to create resonance at certain spin speeds. Adding a ¾‑inch plywood base under the washer spreads the load, but it can also raise the machine into an unlevel position if the floor already slopes. A better approach is to shim the front feet individually with metal washers—not plastic, which can crack under load—until the bubble level reads true. This method absorbs floor irregularities without introducing a new angled surface.
Worn Suspension Components
Suspension rods, springs, and friction pads wear out over time, especially in homes with hard water or frequent wash loads. A typical lifespan is 5–7 years for the rod bearings and 3–5 years for the friction pads. When they fail, the drum can sag to one side or bounce excessively.
Mechanism insight: Amana uses two different suspension designs depending on the model year. Older units have metal rods with plastic bushings; newer ones use a single heavy‑duty spring with a counterweight. If you hear a metallic clunk during spin, the rod bushing is likely cracked. Replacement parts—a rod kit—cost about $25–40 and can be swapped in 30 minutes with basic hand tools. This is significantly cheaper than replacing the entire washer, which would run $400–600 for a new Amana top‑loader.

Step‑by‑Step DIY Fix Sequence
This operator flow prioritizes the fixes that are fastest, safest, and most likely to work. Perform each step in order and stop when the shaking stops.
Step 1: Rebalance the Load and Rerun a Spin Cycle
- Open the door and rearrange clothes, ensuring no large items are wrapped around smaller ones.
- Add a few dry towels if the load is unusually small—this helps the pressure switch detect a balanced mass.
- Select “Spin Only” and observe the machine through the first 30 seconds. If it vibrates, move to Step 2.
Likely cause at this point: A single heavy item creating a localized imbalance. This accounts for roughly 45% of all vibration calls to repair services.
Step 2: Check and Adjust the Leveling Feet
- Place a bubble level on the top panel, front‑to‑back and side‑to‑side.
- Turn the front feet clockwise (tighten) or counterclockwise (loosen) until the bubble centers.
- Lock the jam nuts against the washer base.
Friction point: If the floor is uneven, you may need to place a thin metal shim under one foot. Do not use cardboard or rubber mats—they compress over time and reintroduce tilt. Metal washers from a hardware store cost under $2 and last indefinitely.
Success check: After adjustment, the machine should not rock when you push diagonally on the top corners. All four feet must contact the floor.
Step 3: Inspect and Tighten the Suspension Rods (Top‑Load Models)
- Unplug the washer and remove the top panel (two screws at the back, lift and slide forward).
- Locate the four suspension rods—one at each corner. Check that the plastic bushings are fully seated in the bracket.
- Tighten any loose retaining nuts with a 10mm socket. Do not overtighten; they should be snug, not torqued.
Likely cause at this point: Loose bushings allow the rod to shift during spin, creating a knocking sound and vibration. This affects roughly 15% of units after three years of use.
Step 4: Replace Worn Friction Pads (If Available for Your Model)
- Order the correct friction pad kit using your model number (found on the back of the door or inside the lid).
- Access the pads by removing the front kickplate (two screws). The pads sit on the suspension rods inside the tub.
- Pull out the old pads, slide in new ones, and reassemble.
Success check: After replacement, push the drum to one side. It should return slowly to center, not bounce back. If it bounces, the pads are still worn or incorrectly seated.
Step 5: Reset the Control Board
If the washer shows a blinking code you do not recognize—even if it is not a vibration code—unplug the machine or flip the breaker for a full 60 seconds, then plug it back in. Many transient faults clear with this reset, and the imbalance sensor recalibrates on the next cycle.
Verification step: After the reset, run a short cycle with a small load. Listen for rhythmic thumping or banging. Normal operation should produce a steady hum with no violent bouncing. If the vibration returns within the first 30 seconds of spin, proceed to the escalation section below.
Vibration Troubleshooting Quick‑Check
Use this decision aid during Steps 2 or 3. If any item fails, act on it before moving to the next step.
| Check Item | Pass Condition | Fail Action |
|---|---|---|
| Load appears evenly distributed after rearrangement | No large clumps visible | Add or remove items until load is uniform |
| Bubble level shows center within one small mark | Leveling feet tight, floor flat | Adjust front feet; shim if needed |
| No visible shipping bolts on back panel | Bolts removed and spacers discarded | Remove bolts using ½‑inch socket |
| Machine does not rock when pushed diagonally | All four feet contact floor | Tighten jam nuts; shim any foot that lifts |
| Spin cycle does not produce loud thump after 30 seconds | No metallic noise | Inspect suspension rods for cracked bushings |
| Control board shows no unfamiliar error codes | Normal display or familiar code | Unplug for 60 seconds to reset |
Advanced Amana Washing Machine Shaking‑Vibrating Fix: When DIY Stops
The steps above solve 85–90% of vibration issues on Amana washing machines. If you have completed all five steps and the shaking persists, the problem may be deeper than what home repair can safely address.
Stop DIY and escalate if you notice any of these specific signs:
- Grinding sound during spin plus vibration: This indicates drum bearing failure. The bearing race is corroded, and the repair typically costs $150–250 in labor alone. If the washer is over eight years old, replacement is more cost‑effective than repair.
- Wobbling drum with a clunk when rotated by hand: This points to a cracked tub spider—the three‑arm metal piece that supports the inner tub. The spider can crack from age or impact, and replacement requires removing the entire outer cabinet.
- Thud sound when spin starts, followed by violent shaking: An internal concrete counterweight has likely broken loose and shifted. Reattaching it requires disassembling the washer body, which most DIY owners cannot do safely.
How to confirm the fix worked before moving on: After completing the steps above, load a medium‑sized mixed load (3–4 towels and a few shirts) and run a complete cycle. Stand near the machine during the spin phase. Normal operation produces a steady hum with minor oscillation. If the machine moves more than one inch from its original position, or if you can feel vibration through the floor at a distance of three feet, recheck the leveling feet and load distribution. If both are correct, the issue is mechanical and requires professional diagnosis.

Frequently Asked Questions
Can a single sock really cause my Amana washer to shake?
Yes, but indirectly. A single sock has very little mass on its own. The issue is that it often gets trapped inside a heavier item—like a bedsheet—during the wash cycle. The sock absorbs water and adds an uneven 0.3–0.5 pound to one side of the drum, throwing off the balance. Always check for tangled laundry after mixed‑load cycles.
Is it safe to run a vibrating Amana washer until the cycle ends?
No. Continuous severe vibration can damage the motor bearings, loosen internal wiring connections, and crack the plastic tub housing. Stop the machine immediately, rebalance, and restart. A few seconds of vibration during an unbalanced spin is normal, but if it lasts more than 10 seconds, intervene.
How often should I check the leveling feet?
Every time you move the washer or notice new vibration. Hard water deposits can also cause the jam nuts to loosen over time—inspect them annually as part of your maintenance routine. If you have a wooden subfloor, check more frequently because wood expands and contracts with humidity, affecting the machine’s stability.
Does the washer’s age affect the likelihood of vibration issues?
Yes. Machines older than seven years are more prone to suspension wear and bearing deterioration. If you have an older Amana model that previously ran quietly and now shakes, focus your inspection on the suspension rods and friction pads first, as these are the most common age‑related failures.
