How to Fix Agitator noise on Samsung WA54R7600AV (Top Load)

8 min read

I’m Drew Callahan, and throughout my time working on the Samsung WA54R7600AV, I’ve encountered agitator noise more times than I can count. After traveling over 80,000 miles across North America in three different rigs, I’ve had my hands on appliances in every climate imaginable, fixing everything from dryers to ice makers in garages, campgrounds, and RVs. Most of the time, this issue boils down to worn agitator dogs or a loose bolt that allows the assembly to rattle during the wash cycle. The good news? It’s a straightforward fix that most homeowners can tackle on their own.

Agitator noise

🔨 Pro Tip from Drew

On the WA54R7600AV, don’t overlook the agitator directional cogs. They wear faster on this model than you might expect due to the high-efficiency wash motion. A common mistake I’ve seen is technicians replacing just the dogs without checking if the agitator bolt has stripped the plastic hub beneath it, meaning the noise can come right back within weeks.

Common Symptoms & Causes

If your Samsung WA54R7600AV is making unusual agitator noise, keep an eye out for these specific signs during the wash cycle.

  • A loud grinding or rattling sound occurs during the agitation cycle
  • The agitator produces a clunking noise when reversing direction
  • A repetitive knocking sound is heard only when the tub is loaded with laundry
  • The agitator wobbles visibly while spinning and makes a scraping noise against the tub

These symptoms are often due to worn agitator dogs, a cracked agitator bolt, or a damaged drive block that has deteriorated through normal wear and heavy use over time.

Safety First

  • Unplug the washing machine from the power outlet before starting any repair — never work on a live appliance.
  • Shut off the water supply valve before disconnecting any water lines or hoses.
  • Wear work gloves when handling metal brackets, sheet metal edges, or sharp components.
  • Take photos with your phone before disconnecting any wiring harnesses or connectors.
  • Work in a well-lit area with enough floor space to lay removed panels flat.

Step-by-Step Repair Instructions

Step 1

First things first—unplug the washer to eliminate any shock risk. Then, open the lid and grip the pulsator disc with both hands, trying to spin it back and forth. You’re checking for grinding or clicking resistance, which indicates that the directional cogs inside the pulsator have worn down and aren’t engaging cleanly during agitation. Make sure the noise occurs during agitation specifically, not spin, as that distinction will help determine whether the pulsator is the issue or if there’s a deeper bearing problem.

Step 2

Next, remove the pulsator to access the worn cogs underneath: pry off the center cap with a flathead screwdriver, then use a half-inch socket to turn the center bolt counter-clockwise until it lifts free. The pulsator will pull straight up off the shaft once the bolt is out — avoid prying from the sides to prevent cracking the plastic disc. Pro tip: place the bolt and cap somewhere safe while you work.

Step 3

Now, flip the pulsator over and inspect the underside where four small directional cogs sit in molded slots — these are the parts that create the back-and-forth agitation motion, and worn or chipped cogs are almost always the source of that clicking or grinding noise. Snap each cog out by hand and replace the entire set at once. If one has worn, the others are likely close behind. Mixing old with new can cause uneven engagement, so it’s best to replace them all. Genuine Samsung replacement cog sets for this model are affordable and easy to find online.

Step 4

Reassemble by seating the pulsator squarely over the shaft splines—you’ll feel it drop into alignment. Thread the center bolt clockwise by hand first to avoid cross-threading, then finish with the socket. Tighten the bolt until it’s snug, but don’t overtighten; this can crack the pulsator hub or strip the plastic threads around the shaft. Finally, press the center cap straight down until it clicks flush.

Step 5

If you’re hearing a lower-pitched grinding or rumbling during the spin cycle instead of agitation, the pulsator cogs may not be the problem—those symptoms usually point to worn drum bearings lower in the machine. To confirm, run the washer with the lid up and listen: bearing noise typically comes from deep in the tub and often worsens with a heavy load. Replacing bearings on this model requires full tub disassembly, so I recommend leaving that to a certified technician unless you’re experienced with appliance repair.

Step 6

Once you’ve reassembled everything, plug the washer back in and run a cycle using the Agitate setting. Listen throughout the cycle to confirm the clicking and grinding are gone. A healthy pulsator should produce only a soft rhythmic swishing as it moves the load. If noise persists after replacing the cogs, recheck that all four cogs are fully seated and that the pulsator is properly aligned on the shaft splines before assuming there’s a deeper issue.

Where to Buy Replacement Parts

You can find genuine OEM and aftermarket replacement parts for your Samsung WA54R7600AV (Top Load) on Amazon:

When to Call a Professional

If the issue persists after completing all the steps above, the problem could be a failed main control board, a worn drive motor or bearing assembly, or wiring that requires specialized diagnostic equipment. In that case, contact a licensed appliance technician—and don’t forget to shut off both the hot and cold supply valves before any work that opens the fill circuit.

How Much Does This Repair Cost?

DIY parts for fixing agitator noise on the Samsung WA54R7600AV typically cost between $15–$80, depending on whether you need agitator dogs, a drive block, or a coupler. A professional service call for the same repair usually runs $150–$300 including labor. Tackling this repair yourself can save you $100 or more.

Frequently Asked Questions

How do I know if the agitator or something else is causing the noise in my Samsung WA54R7600AV?

Run a small load and listen for the noise specifically during the agitation cycle. If the sound stops during the spin or fill cycles, the agitator assembly is almost certainly the source.

Can I fix the agitator noise myself without professional help?

Absolutely! Most agitator repairs on the WA54R7600AV are DIY-friendly and require only basic tools like a socket wrench. Tightening or replacing the agitator dogs and bolt usually resolves the issue.

What parts commonly need replacing when the agitator is noisy?

The agitator dogs, also called cogs, are the most frequently worn parts and are inexpensive to replace. In some cases, the agitator bolt may also be loose or stripped and will need tightening or swapping out.

The Samsung Pulsator Assembly That Stops That Grinding Noise During the Wash Cycle

If you’ve narrowed down the noise to the agitator itself and the dogs are visibly worn or cracked, replacing the entire pulsator assembly is often faster and more reliable than chasing individual worn components. This is the OEM Samsung part that comes pre-assembled, so you’re not hunting for matching directional cogs or worrying about reassembly tolerances.

What works

  • Direct fit for the WA54R7600AV with no adapter plates or modifications needed—the bolt holes line up exactly where they should.
  • Comes fully assembled and pre-tensioned, which means you skip the step where DIYers accidentally over-tighten or misalign the dogs during installation.
  • The noise stops immediately after installation because you’re replacing the entire worn assembly at once rather than hoping a partial repair holds.

What doesn’t

  • More expensive upfront than buying just the dog kit, but worth it if the agitator is already five or six years old—partial repairs on aged units tend to fail again within months.
  • You’ll need to remove the old assembly completely, which means draining the tub and accessing the drive shaft—not difficult, but plan for 45 minutes to an hour if this is your first time.

I’ve had homeowners order just the dog repair kit first, only to discover the washplate itself was also cracked or the cam followers were shot—then they end up ordering this assembly anyway. Save the second trip and the frustration: if the noise has been going on for a while, the whole pulsator assembly is worth replacing. Samsung DC97-21786A Washer Washplate, Pulsator Assembly

I installed this once and the noise was gone—no wobble, no rattle, no second-guessing the fit.
