Washing Machine Making Noise? What Each Sound Means — and What To Do
A noisy washing machine is one of the most common and most misread appliance problems. A loud bang, a grinding roar, a high-pitched squeal, and a rhythmic thumping during spin all sound alarming — but each sound points to a different component, a different cause, and a very different repair cost. This guide walks through every noise type in detail, what’s actually causing it, whether it’s safe to keep running the machine, and when a technician needs to diagnose it before the problem gets significantly more expensive.
Diagnosing Your Washer Noise — By Sound Type
The sound your washer is making is the most direct diagnostic clue. Different components fail in acoustically distinct ways — knowing which sound matches which cause tells you immediately how urgent the situation is and what a technician will be looking at.
Grinding or Roaring During Spin
A low-pitched roar or grinding that increases in volume and pitch as the spin speed rises is almost always drum bearing failure. This is the most serious noise your front-loader can produce. Drum bearings support the entire weight of the rotating drum and drum shaft. When they fail — most often from water exposure after a door seal crack — they produce a roaring sound at low spin speeds that becomes loud and grating at high spin speeds.
Allowing a machine to run with failed bearings risks catastrophic drum damage within weeks. The noise will worsen consistently with every wash cycle. This is a professional repair. More on bearing failure →
✕ Professional repair requiredLoud Banging or Thumping During Spin
A rhythmic banging or thumping during the spin cycle has three likely causes, each distinguishable by context. If it happens only occasionally or on certain loads — especially single heavy items like jeans or towels — unbalanced load is the cause: open the machine, redistribute items, and restart spin. If it happens consistently on every load regardless of size or type, worn shock absorbers (front-loaders) or suspension springs (top-loaders) are the mechanical cause. If it is accompanied by the drum feeling loose when pushed by hand with the machine off, a drum support bracket or spider arm may be cracked.
Shock absorber replacement is a moderate-cost repair that resolves consistent banging on front-loaders. Spider arm fracture on Samsung and LG is a more involved repair that affects the financial repair decision. Spin-related diagnosis →
◯ DIY possible for load rebalancing; professional for mechanical causesSquealing or Squeaking During Agitation or Spin
A high-pitched squeal — especially one that starts during agitation and continues into spin — is most commonly a worn drive belt or a dry or failing pulley bearing. Top-loaders with belt-driven motors (most Whirlpool, GE, Kenmore, and Maytag models) develop belt squeal as the belt glazes and loses friction against the pulleys. Squeal that stops when you press lightly on the belt (with the machine off) confirms the belt is the source. Drive belt replacement is a moderate-cost, same-visit repair.
On LG’s direct-drive models, which have no belt, a squealing sound typically indicates a worn drum bearing at its early stage — before it progresses to grinding. Early bearing intervention costs significantly less than a deferred replacement.
◯ Drive belt: professional same-visit repair. Bearing: professional diagnosisClicking or Rattling During Any Cycle
A clicking or rattling sound — particularly one that started suddenly after a recent wash — is most commonly a foreign object that entered the pump or drum: a coin, a button, a small clip, a bra underwire. The clicking is the object moving through the pump impeller or bouncing inside the outer drum. Check the drain pump filter first (lower front panel on front-loaders) — many foreign objects are retrieved there. A rattling that persists after filter cleaning may indicate the object reached the pump housing or outer drum, which requires professional access.
A persistent rattle that sounds structural — consistent regardless of drum position — can also indicate a loose counterweight or bracket inside the machine cabinet.
◯ Filter check: DIY. Persistent internal rattle: professionalLoud Agitation Noise — Banging or Clanking (Top-Load)
A loud clanking or metallic banging specifically during the agitation phase — not spin — in a top-loader is often an agitator problem. The agitator dogs (small plastic ratcheting components inside the agitator column) can wear out, causing the agitator to move loosely and bang against the drum. This produces a loud, irregular clanking during agitation that stops during spin. Agitator dog replacement is one of the least expensive top-load washer repairs and resolves the problem entirely.
On machines where agitator clanking has been ignored for an extended period, the agitator shaft itself can develop wear. Diagnosis by a technician determines whether dogs alone or a full agitator replacement is needed.

A machine that hums but whose drum does not move — or moves barely — is usually a motor that is receiving power but cannot turn the drum. On top-loaders, the motor coupling is the first suspect: it’s a small plastic coupler designed to shear under overload to protect the motor, and it can fail from age or consistently overloaded drums. On front-loaders, a humming motor that produces no drum rotation often points to a capacitor failure (the capacitor provides the starting torque) or significant pump restriction preventing the motor from building speed.
✕ Professional diagnosis required — do not continue running the machineThe Noise That Can’t Wait — Drum Bearing Failure
Of all the noises a washing machine can make, a grinding or roaring sound during spin is the one that requires the most urgent attention. Here is why the progression matters.
Drum bearings in a front-loader are housed just behind the drum, sealed against moisture by the rear bearing seal. In most cases, bearing failure begins not with the bearing itself, but with a failing door boot seal. The front door seal (the thick rubber gasket that creates a watertight seal around the door opening) embeds mineral deposits over time in hard water environments, stiffens, and eventually cracks. A cracked seal allows wash water to weep toward the drum shaft and rear bearing housing during every cycle.
Drum bearings are not designed to be wet. Once water reaches the bearing, corrosion begins within weeks. A bearing that was silent in January and produces a faint hum in February will roar in March and grind in April. The failure is progressive and there is no point at which it stabilizes. Running a machine with failed bearings risks the drum shaft scoring the bearing housing in the outer tub — which converts a bearing repair into a full drum and outer tub replacement at several times the cost.
California hard water note: In Southern California cities with high mineral content — Ventura (~479 ppm), Glendale (~360 ppm), Burbank (~315 ppm), Mission Viejo and Encinitas (~278 ppm) — door boot seals degrade faster than in soft-water markets. The seal-to-bearing cascade that causes grinding noise happens at 5–7 years in these cities, compared to 8–11 years in soft-water markets like Sacramento or the Bay Area. If your front-loader is 5+ years old in a SoCal hard water city and showing early grinding noise, prompt attention avoids the more expensive repair.
One or two cycles to finish urgent laundry will not cause catastrophic damage if the grinding is early-stage. Running it continuously for weeks after grinding noise appears risks scoring the drum shaft against the bearing housing — a much more expensive outcome. Get a diagnosis as soon as reasonably possible. A technician can assess how far the bearing has progressed and whether the damage is currently contained to the bearing alone or has extended to the shaft or tub.
Bearing repair is worth doing on most machines under 9–10 years old when it’s a confirmed bearing-only failure with the drum shaft intact. The financial decision changes if the spider arm (the three-arm casting connecting the drum to the shaft) is also cracked — a common combined failure on Samsung and LG front-loaders at 7–10 years. Get the confirmed diagnosis first, then apply the 50% rule against your machine’s replacement cost. Repair vs. replace guide →
Noise by Phase — Quick Diagnostic Reference
| When Noise Occurs | Most Likely Cause | Action |
|---|---|---|
| During fill only | Water hammer in pipes, not the machine | Check household water pressure; install hammer arrestor |
| During agitation, top-load | Agitator dogs, loose agitator, worn belt | Professional diagnosis |
| During agitation, front-load | Drum paddle loose, foreign object | Check drum interior; professional if persistent |
| Early spin only | Unbalanced load, shock absorbers | Rebalance load; if persistent on balanced loads — shocks |
| Mid and high spin | Drum bearings (grinding/roar) or drive belt (squeal) | Urgent professional diagnosis |
| During drain | Foreign object in pump, failing pump motor | Check pump filter; professional if noise persists |
| Any phase, constant rattle | Loose counterweight, bracket, or foreign object | Check filter; professional if structural |
| Machine hums, drum doesn’t move | Motor coupling, capacitor, pump restriction | Do not run; professional diagnosis |
Brand-Specific Noise Patterns
- LG front-load: Bearing failure at 6–9 years, typically downstream of door seal crack. Direct-drive models: no belt squeal.
- Samsung front-load: Bearing and spider arm failure at 6–9 years. Spider arm cracks often produce thumping before grinding begins.
- Bosch 500/800: Pump filter restriction (hard water scale) produces a strained humming during drain. Bearing noise similar profile to LG.
- Whirlpool/Maytag top-load: Drive belt squeal and agitator dog rattle are the most common noise calls. Motor coupling failure produces humming with no drum movement.
- GE top-load: Suspension spring failure — banging during spin when springs disengage. Distinctive loud single-impact thump at spin start.
What To Check Before Calling a Technician
-
1
Confirm it is the washing machine and not the pipes
Water hammer — a loud banging in the walls when the fill valve opens or closes — comes from household water lines, not the machine. Run only the fill cycle and listen whether the sound comes from inside the drum or from the walls. Pipe hammer is resolved with a water hammer arrestor on the supply line, not a washer repair.
-
2
Check that the machine is level
A machine that is even slightly unlevel will rock during spin, producing thumping and walking. Use a spirit level across the top of the machine, front to back and side to side. All four feet should be firmly on the floor with no rocking. Adjust the leveling feet at each corner by hand or with a wrench. Anti-vibration pads under the feet further dampen resonance on hard floors.
-
3
Check the drum for foreign objects
Reach into the drum and run your hand around the entire inner surface. Check the perforations in the drum wall — a coin edge caught in a perforation will click on every drum rotation. Check the door seal fold on front-loaders: bra underwires and small clips lodge in the seal groove and rattle during agitation. Remove any foreign material you find.
-
4
Clean the drain pump filter (front-loaders)
A foreign object that has passed through the drum to the pump filter will produce clicking or rattling during the drain phase. Clean the filter (lower front access panel) and inspect what comes out. Coins, buttons, and small clips are retrieved this way on a regular basis. Full instructions: drain pump filter guide →

5
Identify when in the cycle the noise occurs and note whether it is worsening
Note the cycle phase (fill, agitation, spin, drain), the character (grinding, banging, squealing, clicking), whether it is getting louder over successive washes, and whether it is consistent or intermittent. This information is the most useful thing you can provide a technician at the start of a diagnostic visit and eliminates guesswork.
Frequently Asked Questions — Washing Machine Making Noise
It depends on the sound. A thumping noise on certain loads that stops when the load is redistributed is an unbalanced load — safe to continue with correct loading. A consistent grinding or roaring sound that is present on every load and worsens with spin speed is drum bearing failure — not safe to continue without diagnosis. Running a machine with failed bearings causes progressive damage to the drum shaft and outer tub that dramatically increases the repair cost. Get a diagnosis promptly.
Sudden onset of grinding during spin in a machine that was previously quiet almost always indicates drum bearing failure. In front-loaders, this typically follows a door boot seal failure that allowed moisture to reach the bearing housing. The progression from seal crack to early bearing noise can take 6–18 months. In California hard water cities, where seal mineral degradation is faster than the national average, the seal-to-bearing cascade often occurs at 5–7 years on unserviced machines. The grinding will worsen with every wash cycle until the bearing is replaced.
Clanking specifically during agitation on a top-loader is the characteristic sound of worn agitator dogs — small plastic ratcheting components inside the agitator that engage and disengage the directional motion. When they wear out, the agitator can move loosely and strike the drum. A secondary possibility is a loose agitator that is not properly secured to its shaft. Both are diagnosed and repaired in a single visit. It is one of the least expensive top-load washer repairs.
Cost varies significantly by the cause. Foreign object retrieval may require only a diagnostic visit if the object is in the pump filter. Agitator dog replacement, drive belt replacement, and shock absorber replacement are moderate-cost repairs. Drum bearing replacement is a more involved repair — it requires significant disassembly on most front-loaders — and is priced accordingly. The right sequence is to get a confirmed diagnosis and written estimate before authorizing any work. California law requires a written estimate before repairs over $100. Any technician should be willing to provide one. California washer repair cost guide →
A strained or struggling hum during the drain phase on a Bosch front-loader — particularly the 500 and 800 Series — is typically the drain pump motor working against restricted flow from mineral scale in the pump housing. In Southern California cities with hard water (San Diego County at 220–280 ppm, Ventura County at 350–480 ppm), scale accumulates in the pump housing interior faster than in soft-water markets. This is separate from the accessible pump filter — the housing interior requires professional descaling. If the machine later throws an E18 drain error, scale is the confirmed cause.
