Grinding only during drain
The wash action sounds normal, then a rough grinding or gravelly buzz starts when water pumps out.
Start here: Focus on the washer drain pump and anything caught in the pump or drain path.
Washer noise troubleshooting
Washer Grinding Noise
Direct answer: A washer grinding noise is most often caused by something rubbing where it should not: an item trapped between the tubs, a drain pump chewing on debris, a loose or worn washer drive belt, or support parts that let the basket move badly during spin.
Most likely: Start by pinning down when the noise happens. Grinding during drain points toward the washer drain pump. Grinding only as the basket ramps into spin often points toward a belt or support problem. A metal-on-metal scrape when you turn the basket by hand points more toward something stuck in the tub area or a serious bearing issue.
Listen first, then touch and look. Reality check: a lot of "grinding" calls turn out to be a coin, bra wire, zipper, or small screw scraping where it should not. Common wrong move: running another load to see if it clears up. If something is trapped or a pump is chewing debris, that usually makes the repair bigger, not smaller.
Don’t start with: Do not start by ordering a washer motor or washer control board. Those are not the usual cause of a true grinding sound.

What the grinding noise sounds like
Grinding as spin starts
The noise shows up when the basket first speeds up, sometimes with extra shaking or a rubbery slap.
Start here: Check for an off-balance load, washer leveling, suspension movement, and a worn washer drive belt if your model uses one.
Scraping when you turn the basket by hand
With power off, the basket feels rough or makes a scrape even without a cycle running.
Start here: Look for a trapped item between the inner basket and outer tub before assuming major internal failure.
Heavy grinding with burning smell or leaking
The noise is harsh, gets worse fast, or comes with hot rubber smell, water under the washer, or visible wobble.
Start here: Stop using the washer and treat it as a likely seized support, belt, pump, or bearing-level problem.
Most likely causes
1. Debris in the washer drain pump
A pump full of coins, hair pins, bra wire, or hard lint makes a rough grinding or rattling sound mostly during drain.
Quick check: Run a drain or spin cycle with no clothes and listen low at the front or back near the pump area.
2. Something trapped between the washer tubs
A small metal item can scrape the basket once per turn or make a steady grind when the basket moves under load.
Quick check: With the washer unplugged, turn the basket by hand and listen for a repeating scrape.
3. Worn or loose washer drive belt
On belt-driven washers, a glazed, frayed, or loose belt can make a rough grinding-slash-slipping sound as the basket starts spinning.
Quick check: Look underneath for black dust, belt fraying, or a belt riding crooked on the pulley.
4. Weak washer suspension or shock parts
If the tub drops or swings too far, parts can rub and the machine can sound like it is grinding when the real issue is bad support during spin.
Quick check: Press the tub down by hand. If it bounces several times or sits noticeably off-center, support parts are suspect.
Step-by-step fix
Step 1: Pin down exactly when the noise happens
The point in the cycle tells you more than the sound alone. Pump noise, tub scrape, and spin-support noise happen at different times.
- Run a short rinse and spin cycle with the washer empty.
- Listen for the first moment the grinding starts: fill, wash agitation, drain, spin ramp-up, full spin, or coast-down.
- Stand to the front, then the back, and note where the sound is strongest.
- Open the lid or door after the cycle ends and slowly turn the basket by hand with power disconnected.
Next move: If you can tie the noise to one part of the cycle, the next checks get much narrower and you avoid guess-buying. If the noise is loud all the time or hard to place, move to the simple physical checks next and stop using the washer if the sound is severe.
What to conclude: Drain-only noise usually points low to the pump area. Noise during hand-turning points to a tub scrape or support issue. Noise only during spin points more toward belt or suspension trouble.
Stop if:
- You smell burning rubber or hot electrical odor.
- The washer is leaking while making the noise.
- The basket is hard to turn or feels seized.
Step 2: Rule out a trapped item and load-related rubbing
This is common, cheap to fix, and easy to miss. A single coin, bra wire, zipper, or screw can sound much worse than it is.
- Unplug the washer.
- Check the basket holes, door boot area on front-loaders, and under the agitator or wash plate area if visible for loose metal items.
- Look for fresh scrape marks on the basket, tub opening, or door boot.
- Remove any bulky mixed load and test the washer empty, then with a small balanced load of towels.
- If the basket scrapes once per turn by hand, stop and inspect more closely before running another cycle.
Next move: If the noise disappears after removing debris or correcting the load, you likely caught a simple rub before it damaged anything else. If the scrape remains with an empty washer, the problem is likely in the pump, belt, or support system rather than the laundry load itself.
What to conclude: A repeating scrape usually means something physical is contacting the basket. A noise that only happens with heavy uneven loads leans toward balance, leveling, or worn support parts.
Step 3: Check the washer drain pump path if the noise happens during drain
A drain pump full of debris is one of the most common true grinding noises on a washer, and it usually shows up only when water is pumping out.
- Disconnect power and shut off water if you need to move the washer.
- If your washer has a serviceable pump cleanout, open it carefully with towels ready and remove coins, pins, lint clumps, or other debris.
- Inspect the drain hose connection at the pump for obstructions if accessible.
- Spin the pump impeller gently if visible. It should turn with some resistance but should not be jammed, broken, or sloppy on the shaft.
- Run a short drain cycle after reassembly and listen again.
Next move: If the grinding is gone and the washer drains normally, the pump was likely chewing on debris rather than failing outright. If the pump still grinds empty and clear, or the impeller is damaged or loose, the washer drain pump is the likely repair.
Step 4: Inspect belt, pulley area, and washer support movement
If the noise shows up as the basket starts spinning, the drive and support parts are the next most useful checks.
- With power disconnected, remove the lower or rear access panel if your washer design allows safe access.
- Look for a washer drive belt that is frayed, glazed, cracked, or leaving black dust underneath.
- Check whether the belt is riding centered on the pulleys and not twisted.
- Push down on the tub and let it rise. It should settle quickly, not bounce several times.
- Make sure all washer leveling feet are firmly on the floor and the cabinet is not rocking corner to corner.
Next move: If leveling or load correction stops the noise, you likely had a support or setup problem rather than a failed internal part. If the belt is visibly worn, replace it. If the tub bounces excessively or sits low on one side, worn washer suspension rods or washer shock absorbers are the stronger suspects.
Step 5: Decide between a supported repair and a pro call
By this point you should know whether you have a simple pump, belt, or support repair, or a deeper internal problem that is not a good guess-and-go job.
- Replace the washer drain pump if the noise is clearly drain-only, the pump is clear, and the impeller or pump body is still grinding.
- Replace the washer drive belt if it is visibly worn, slipping, or shedding dust and the pulleys are otherwise sound.
- Replace the washer suspension rods or washer shock absorbers if the tub movement is excessive and the grinding happens during spin from basket travel.
- Call a service pro if the basket grinds when turned by hand with no visible trapped item, or if there is heavy wobble, rust streaking, or a deep bearing growl.
A good result: A correct repair should leave the washer draining and spinning smoothly without fresh scraping, grinding, or cabinet movement.
If not: If the same grinding remains after the supported repair, stop there and have the washer evaluated for a bearing, tub, or drive hub problem.
What to conclude: The page supports the common repairable causes. A hand-turn grind that stays after debris checks is where the repair usually gets more invasive and less homeowner-friendly.

FAQ
Why does my washer make a grinding noise only when draining?
That usually points to the washer drain pump. Coins, pins, and other hard debris can get into the pump and make a rough grinding sound. If the pump is clear but still noisy, the pump itself is often worn.
Can an unbalanced load sound like grinding?
Yes. A badly unbalanced load can let the tub swing far enough to rub or slam, especially during spin ramp-up. It is more common with bulky items, small single-item loads, or a washer that is not level.
Is a washer grinding noise always a bad bearing?
No. Bearings can cause a deep rough growl, but they are not the first thing to assume. Trapped items, pump debris, belt slip, and worn suspension parts are all more common homeowner-level causes.
Should I keep using the washer if it still works?
Not if the noise is harsh, getting worse, or comes with leaking, burning smell, or visible wobble. Continued use can damage the tub, pump, belt, or support parts and turn a smaller repair into a major one.
How do I tell pump noise from basket noise?
Pump noise usually happens during drain and sounds strongest low in the machine. Basket or tub noise often shows up during spin or when you turn the basket by hand with the washer unplugged.
What if the basket grinds by hand even with no clothes inside?
That is a stronger sign of a trapped item in the tub area or a deeper internal support or bearing problem. If you cannot find a visible object causing the scrape, it is time to stop running the washer and consider a service call.
