Why Is My Washer Making a Grinding Noise?
Last updated October 31, 2026
A washer making a grinding noise usually means metal or hard plastic is rubbing where it shouldn't: a worn drum bearing, a foreign object trapped between the tubs, a jammed drain pump, or worn agitator cogs on a top-loader. The timing narrows it down. A grind that builds into a roar as spin speed climbs points to the bearings, a scrape from the first turn of every cycle means something is trapped, grinding only while draining is the pump, and grinding only during agitation is the agitator cogs.
It's worth acting on. A bearing left running can damage the tub seal and turn a bearing job into a whole-tub job.
Separate grinding from banging and thumping
Grinding is a continuous metallic or harsh plastic scrape or rumble. Banging, thumping and clunking belong to a different fault family: an unbalanced load, worn suspension, or shipping bolts still in the back. Those lead to different fixes, and mixing them up sends you after the wrong part.
Some loud sounds are normal and need no repair at all:
- The motor reversing and the gear sounds of newer drive systems.
- The pulsing sound some top-loaders make as the agitator changes direction, often compared to an electric can opener.
- A single clank from the mode shifter between agitate and spin.
- A light clanking when you spin the tub by hand on machines with a ball-balancing ring.
If the noise matches one of those, there is nothing to fix.
Match the timing to the cause
| When it grinds | Most likely cause | Who fixes it |
|---|---|---|
| Only on spin, louder as speed climbs, jet engine roar | Worn drum or tub bearings | Technician |
| Every cycle from the start, metallic scrape | Foreign object between inner and outer tub | Technician on front-load; sometimes DIY on top-load |
| Only while draining or pumping out | Jammed drain pump impeller | Often DIY through the filter or coin trap |
| Only during agitation, top-load, upper agitator spins freely by hand | Worn agitator dogs or directional cogs | DIY, under an hour |
| Grind plus bang on spin, drum sits low or off-center | Cracked spider arm or worn suspension rods and shocks | Technician |
| Grind plus squeal, worse with heavy loads | Belt, drive pulley or motor coupling | Often DIY |
| Harsh grind during agitation plus oil under the machine | Transmission or gearcase on a top-load | Technician, often replace |
| Brand-new front-loader, violent noise | Shipping bolts not removed | DIY, free |
Cause by cause, what to confirm and what fixing involves
Drum and tub bearings
The bearing sits behind the tub seal. When the seal fails, water reaches the bearing, the grease washes out, and metal runs on metal. Confirm it with the hand-spin rumble and free play in the drum. The machine has to be largely taken apart to reach it, so it is a technician job for most households.
Foreign object between the tubs
Bra underwires and coins are the usual culprits. A coin can be flung hard enough to pierce the plastic outer tub. On a front-loader the tub usually has to be split; on some top-loaders the object can be reached from the top.
Drain pump
A coin, bra wire or piece of glass jams the impeller. The grind happens only while draining and often comes with a drain error code. Many front-loaders have an accessible filter or coin trap, which makes this the most DIY-friendly cause on the list.
Agitator dogs and directional cogs
On a top-loader, the upper agitator turns freely by hand and the machine grinds or ratchets during agitation only. It is a small, inexpensive part and a short job.
Spider arm
The cast arm that carries the drum on a front-loader can crack. The drum then sits low or off-center and grinds and bangs on spin. A technician job.
Suspension rods and shock absorbers
Worn suspension lets the drum move too far. The noise is more bang than grind, but it often comes with a grind at speed. A technician job.
Belt, drive pulley and motor coupling
A glazed or frayed belt or a worn coupling grinds or squeals, and it gets worse under heavy loads. Often a DIY job.
Transmission and gearcase
A deep, harsh grind during agitation with oil leaking underneath points to the transmission on a top-loader. A technician job, and often the point where replacement makes more sense than repair.
Shipping bolts
On a new front-loader, bolts left in the back hold the drum rigid. The machine shakes and grinds violently. Removing them is free and takes a few minutes.
Sealed versus serviceable tub
On many modern machines the bearing is pressed into a sealed tub half, so a bearing failure means replacing the whole tub assembly rather than fitting a bearing kit. This is the single biggest factor in whether the repair stays affordable.
Is it safe to keep using the washer while it grinds?
Stop running it if the noise is a bearing rumble, a metallic scrape, or comes with a burning smell, water underneath, or rust streaks on clothes. Continuing damages the seal, the spider arm and eventually the tub, turning a bearing job into a tub replacement. A machine with bearing noise should not run more than a couple of weeks while you arrange the repair.
A jammed pump should be cleared before the next load, because running it can burn out the pump motor. Agitator cogs are not urgent: the machine will wash, just poorly, until they are fixed. Shipping bolts should come out before the next cycle.
Call a technician and stop using the machine if the noise happens with it switched off, the tub won't spin, or the drum is visibly off-center.
Repair or replace, the money decision
Use the 50% rule: if the repair costs more than about half the price of a comparable new machine, replacement usually wins. Weigh age next. Washers typically last around 10 years, and past about 8 years you should lean toward replacement, especially for a big repair.
Whether the tub is sealed or serviceable decides a lot. A bearing job on a sealed-tub machine is a tub-assembly job, the classic case where replacement wins. Add the hidden costs of a new machine too: delivery, installation, haul-away and new hoses all count toward the real total.
Each tier of repair brings its own answer. A small part such as agitator cogs, a belt, a coupling or a pump is a straightforward fix worth doing on almost any machine. A mid-level job such as bearings on a serviceable tub is worth it on a younger machine. A tub assembly or a transmission is usually only worth it on a machine that is still young and otherwise sound.
US repair-cost sources put a service call at a modest flat fee, often credited toward the repair, with typical repairs in the low hundreds. Bearing jobs sit in the middle of the range, and tub assemblies at the top of it. The price varies with the part involved, whether the tub is sealed, whether the machine is front-load, top-load, compact or a combo, local labor rates, and whether the service call fee is credited.
Grinding in a compact or all-in-one washer
Compact and portable washers often have small plastic tubs and pump impellers that jam easily on coins and lint. When the grind happens only on drain, the pump is the first suspect.
All-in-one washer-dryer combos can grind during the dry phase, from lint, coins or a bra wire in the blower or around the drum. That cause does not exist on a washer-only machine, so note whether the grind happens in wash or dry mode.
Stackable and compact front-loaders share the bearing and foreign-object causes of full-size front-loaders, but they have less room around the tub, so a trapped object is more likely to need a technician.
How to keep it from happening again
- Empty pockets before every load. Coins and hair clips are the top foreign objects.
- Use a mesh bag for underwire bras. Bra wires are the number-one object found between the tubs.
- Don't overload. An overloaded drum strains bearings and suspension and makes any grinding worse.
- Level the machine and adjust the feet so the tub doesn't rub a drain pan. If you use a drain pan, make sure the tub clears it.
- Check that hoses and the power cord aren't rattling against the cabinet.
- On a new front-loader, confirm the shipping bolts are out.
- Run a maintenance cycle and clean the pump filter or coin trap on schedule where the machine has one.
The timing of the noise tells you the cause: spin points to bearings, every cycle to a trapped object, drain to the pump, agitation to the agitator cogs. Run the 5-minute check, stop the machine if it is a bearing or something trapped, and use the 50% rule plus the machine's age to decide between repair and replacement. Empty pockets, bag the underwire bras, skip the overloads and keep the machine level, and the grind is far less likely to come back.
Frequently asked questions
Most grinding calls come down to one question: is the noise a worn part or something stuck where it shouldn't be, and the answer changes what you do next.
Can I still use my washer if it's grinding?
It depends on the cause. Stop for bearing noise, a metallic scrape, a pump jam, or any sign of water or rust. Worn agitator cogs can wait, since the machine still washes, just not well.
Is grinding always a broken part?
No. Some drive-system sounds and the clank of a mode shifter are normal. An unlevel machine or a drain pan rubbing the bottom of the tub can also sound like grinding without anything being worn.
Why does my washer only grind with heavy loads?
A heavy load strains the suspension and the bearings, so a part that is already worn gets loud. A worn belt or motor coupling also shows up first under load, because it slips more when it has more weight to move.
Why does it only grind during the spin cycle?
Spin is when the drum turns fastest, so anything loose or worn has its best chance to announce itself. The giveaway is the pattern: a noise that starts faint and builds into a roar as the speed climbs is the classic signature of a failing bearing, while a steady scrape that stays the same pitch from the first turn to the last points elsewhere.
Why does it only grind during agitation?
On a top-loader, the agitator dogs or the transmission are the usual causes. Turn the upper agitator by hand with the machine off: if it spins freely, the cogs are worn.
Why does it only grind when draining?
The drain pump impeller is jammed, usually by a coin, a bra wire or a piece of glass. Clear the filter or coin trap before running another load, or the pump motor can burn out.
What do bad drum bearings sound like?
A rumble or roar that grows with spin speed, like a jet engine. Turning the drum by hand feels gritty or draggy instead of smooth.
How do I tell bearings from a spider arm?
Bearings rumble and let the drum move when you rock it. A cracked arm shows up as a drum that hangs low or off-center, and the sound tracks the rotation rather than the speed.
How long do washer bearings last?
Usually about as long as the machine, roughly 10 years. A failed tub seal shortens that sharply, because water reaches the bearing and washes out the grease.
Can I replace the bearings myself?
Only on a machine with a serviceable tub. On a sealed tub the bearing is pressed into the tub half, so the whole tub assembly has to be replaced, which is best left to a technician.
Why is my new washer grinding?
Shipping bolts left in the back are the usual cause on a new front-loader. They hold the drum rigid, so the machine shakes and grinds violently. Removing them is free.
Is it cheaper to fix or replace?
Weigh the quote against what a comparable new machine would cost, then factor in the age and whether the tub is sealed. A small part is usually worth fixing; a tub assembly on an old machine usually isn't.
