Samsung Washer Making a Loud Noise — Diagnosis
Most likely a coin, button, or underwire is lodged in the drain pump, which produces a rattling or grinding buzz during the drain phase — check the pump filter first. A grinding that rises with spin speed instead points to a worn tub bearing, and a hard bang once per revolution points to a fractured spider arm (part…
The type of noise your [Samsung washer](/blog/samsung-washer-dryer-combo-error-codes) makes, and exactly when it happens, points straight at the failing part. A grind that worsens as the spin speeds up is a bearing; a rhythmic bang once per drum revolution is a cracked support arm; a rattle only during the drain is something caught in the pump. Samsung splits into two mechanical families — WF front-loaders and WA top-loaders — and the likely source differs between them.

Read the noise first#
| Noise character | When it happens | Likely source |
|---|---|---|
| Rattling/grinding buzz | During drain | Object in the drain pump |
| Grinding that rises with speed | Spin, worsening | Tub bearing |
| Hard bang once per revolution | Spin | Spider arm fracture |
| Rapid rattle during ramp-up | Start of spin | VRT balance ring |
| Clunk on speed change | Spin transitions | Worn shock absorber |
| Squeal on startup | Agitate/spin (WA only) | Glazed drive belt |
Most Likely Causes, Ranked#
| Cause | What you'll notice | How likely |
|---|---|---|
| Foreign object in drain pump | Buzz/rattle during drain | 30% |
| Tub bearing wear (WF) | Grind worsens with spin speed | 25% |
| Spider arm fracture (DC97-16509A) | Bang once per revolution | 20% |
| VRT balance-ring ball rattle | Rapid rattle at spin ramp-up | 12% |
| Worn shock absorber (DC66-00470A) | Clunk on spin transitions | 8% |
| Drive belt squeal (WA top-load) | Squeal at agitation/spin start | 5% |
Safety First — Know the Risks
High-voltage components and pressurized water lines create flood and shock risk. A single loose fitting can cause thousands in water damage. Our techs are licensed and insured — let them handle the risk.

Something caught in the drain pump#
The most common noise complaint is a loud buzzing, rattling, or grinding during the drain. Coins, buttons, bra underwire, hair clips, and small toys work their way past the tub and lodge between the pump impeller and its housing. Open the pump filter access at the lower front of a WF model and clear the debris; running the pump against a jammed impeller for long can burn the pump motor, so address this one promptly.
A worn tub bearing#
On WF front-loaders the main tub bearing is pressed into the rear outer-tub housing. After roughly 6 to 10 years — sooner if the shaft seal has leaked water onto it — the bearing races wear and metal rubs on metal, producing a grind that gets louder as spin speed climbs. Because the sound tracks with RPM, a spin test that ramps from low to high makes it unmistakable.
The Real Cost of DIY
Average DIY attempt: $150-400 in tools you may use once, plus the risk of further damage. Our diagnostic visit costs $0 — we find the problem and give you an honest quote.

A fractured spider arm#
Samsung's aluminum spider (part DC97-16509A) is a three-spoke casting that ties the inner drum to the drive shaft at the rear. Detergent residue drives galvanic corrosion that weakens the arms at the hub, and once an arm cracks you get a heavy bang once per drum revolution during spin. This one does not improve on its own and eventually damages the drum, so confirm it before it spreads.
Balance ring, shocks, and belt#
The VRT balance ring on WF models holds three steel balls in a fluid channel; after about 5 to 7 years the balls develop flat spots and clatter during spin acceleration as a distinctive rapid rattle. Worn shock absorbers (part DC66-00470A) develop play in their ball-socket joints and clunk as the tub shifts through spin transitions. On belt-driven WA top-loaders, a glazed belt slips on the motor pulley and squeals when torque demand peaks at agitation or spin start.

When to act and when you can wait#
Some of these noises are urgent and some can ride for a load or two. A drain-pump rattle should be cleared within about two weeks, because running the pump against a jammed impeller risks burning out the pump motor. Bearing grinding is a higher priority — left to worsen, it can score the shaft and force a full tub replacement rather than a bearing swap. A spider-arm bang will not heal on its own and steadily chews at the drum, so it is worth scheduling promptly. The balance-ring rattle and a belt squeal are the least destructive; they are irritating but rarely cause secondary damage, so you can plan those repairs at your convenience.
Preventing washer noise#
Most noise complaints trace back to habits you can change. Empty pockets before loading, since coins are the number-one source of drain-pump noise, and use a mesh bag for anything with underwire, hooks, or small hardware. Run a Self Clean+ cycle monthly to clear the detergent residue that accelerates spider-arm corrosion, and keep the machine level so the tub does not load the shocks and bearing unevenly. None of this reverses a worn part, but it meaningfully delays the wear that produces the loudest failures.
Is It Worth Your Time?
Washer problems have dozens of possible causes from bearings to control boards. Average DIY troubleshooting: 3-5 hours plus parts ordering delays. Our technician diagnoses the issue in about 30 minutes — same-day appointments available.

How to check it yourself#
- Unplug the washer before opening any panel.
- Match the noise to the reference table above to narrow the source.
- Clear the drain-pump filter — the highest-yield check on any drain-phase noise.
- Run a spin test and listen for a grind that rises with speed (bearing) versus a bang once per turn (spider).
- Rock the empty tub by hand to feel for bearing roughness or loose shocks.
DIY or call a pro?#
Clearing the drain pump and inspecting the belt are within reach for most owners, but a tub bearing, a spider arm, or a shock-absorber set means splitting the tub — a job for a technician. Catching a bearing or spider early is worth it because ignoring either eventually ruins the drum. If the noise is coming from inside the tub rather than the pump, book a diagnostic and we will confirm the part before any teardown.
