Washing Machine Smoking or Smells Like Burning? What to Do First – and How to Find the Cause

If your washing machine is smoking or smells like something burning, stop the cycle and cut the power before you read another word. Smoke or a burning smell from an established washer is never normal, and the answer is never “run it again and see if it does it again.” There is exactly one common harmless case — a faint odor from a brand-new machine in its first few weeks — and I’ll show you how to tell the difference below.

This guide covers what to do in the first two minutes, how the type of smell points to the cause (rubber vs. electrical vs. hot metal), which checks are safe to do yourself with the machine unplugged, and which ones genuinely belong to a technician. Quick note on who’s writing this: I’m a homeowner who fixes his own stuff, not a licensed electrician or appliance tech. So every safety-critical claim here is cited to the NFPA, the CPSC, the U.S. Fire Administration, or manufacturer documentation — and I’ll tell you plainly where DIY should stop.

Seeing smoke or smelling burning right now? Do this first

1. Stop the cycle. Press pause/cancel or turn the dial to off.
2. Unplug the machine — but only if you can reach the plug safely. If the outlet is behind the machine and you’d have to lean over a smoking appliance to reach it, don’t. Flip the circuit breaker for the laundry area instead. This is the standard guidance for any malfunctioning appliance: cut power at the plug if it’s safe, otherwise at the breaker.
3. If you see flames, or smoke keeps coming after the power is off, get everyone out and call 911 from outside. Don’t open the washer door, and never put water on anything electrical.
4. Once the machine is off and the smoke has stopped, ventilate. Open a window or door. Burnt plastic and rubber fumes are not something you want to stand around in.
5. Do not restart the machine to diagnose it. If your machine has smoked or smelled strongly of burning, every check described in this guide is done with the machine unplugged — a check that would require the machine to be running is not a DIY check. (The one exception, for a brand-new machine with only a faint odor and zero smoke, is the new-hose fill test below.)

The caution isn’t theatrical. In the most recent detailed NFPA study of laundry appliance fires (published 2017, covering 2010–2014), U.S. fire departments responded to nearly 16,000 home fires a year involving washers or dryers. Dryers cause the large majority (92%), but washing machines still account for roughly 620 fires a year — and the washer fires are a different animal. Per the same NFPA report, the first thing to ignite in a washer fire is most often electrical wire or cable insulation (26%) or the appliance housing itself (24%). In other words, washer fires usually start as electrical fires, which is why a sharp electrical smell gets treated more seriously than a rubber one throughout this guide.

The one exception: a new washer can smell for a while

If your machine is only days or weeks old, there’s a decent chance nothing is wrong. Two documented, normal break-in smells:

• New motor coatings. LG’s support documentation says a new washer’s motor coils and the insulation around them heat up in normal use and can give off an electrical or burning-rubber odor that should stop after 10 to 20 full cycles.
• New rubber inlet hoses. GE notes that fresh inlet hoses can put off a strong rubber odor that gets mistaken for burning. Their diagnostic is simple: start a hot fill and stop the machine before it agitates. If you smell it during fill only — no motor or pump running — it’s just the hoses, and it fades with time. Only run this test on a new machine with a faint odor and no smoke; a machine that has actually smoked stays unplugged.

Two more things worth knowing here. First, if your machine has a drying or sanitary cycle, LG documents that the door gasket itself heats up during those high-temperature cycles and can give off a burning odor, especially when the machine is new or when lint reaches the heater. Second — and this applies to any machine, new or old — check whether yours has been recalled. In December 2022, Samsung recalled about 663,500 top-load washers because they could short-circuit and overheat, after 51 reports of smoking, melting, or fire. Search your model number at cpsc.gov/Recalls; it takes two minutes and the fix, when there is one, is free.

How to tell break-in smell from a real problem: a normal new-machine odor is faint, doesn’t come with any visible smoke, and fades over the first weeks. A strong or acrid smell, any visible smoke, or an odor that gets worse instead of better is a fault — and on a machine that new, it’s a warranty call, not a screwdriver job. Don’t open up a machine that’s under warranty.

What the smell is telling you

Before you open anything, the smell itself plus the moment it shows up narrows the field considerably. This is the diagnostic order I’d work through:

What you notice	Most likely source	Yours to check?
Burnt rubber, strongest during or after the spin cycle	Drive belt slipping or worn (belt-drive machines)	Yes — unplugged
Burnt rubber on a front-loader, black scuff marks near the door seal	Door gasket rubbing the drum, or an item trapped in the gasket	Yes
Burning smell during or right after draining, often with a strained hum	Drain pump jammed by a foreign object	Yes — unplugged
Hot or burning smell after washing very large, packed loads	Motor and belt strained by overloading	Yes — it’s a habits fix
Sharp electrical or acrid smell (burnt plastic, ozone), at any point in the cycle	Motor windings, wiring, capacitor, or control board	No — technician
Burning smell plus a grinding or roaring noise that’s been growing for weeks	Tub bearing (or spider arm on front-loaders)	Diagnosis yes; repair usually no
Faint odor, machine less than a month old, fading over time	New motor coatings or new inlet hoses	Yes — see above

One distinction matters more than all the others: rubber smells are usually friction; electrical smells are usually a failing component. A slipping belt is a part-wearing-out problem you can often handle. A burnt-wiring smell means insulation somewhere is cooking, and the NFPA’s electrical safety guidance is unambiguous — a burning or rubbery odor from an appliance, flickering lights, or sparks from an outlet are all on its “call a qualified electrician” list.

Checks you can safely do yourself (machine unplugged)

Unplug the machine before every one of these. Not switched off — unplugged.

Drive belt: the classic burnt-rubber culprit

On belt-drive machines, the motor spins the drum through a rubber belt. As the belt ages it stretches, cracks, or glazes (the surface turns shiny and slick), and under the high load of a spin cycle it slips against the pulley instead of gripping. Slipping rubber against spinning metal makes heat, and heat makes that unmistakable burnt-rubber smell. This isn’t a trivial failure to shrug off: in the NFPA’s washer fire data, a drive belt or V-belt was the first item ignited in about 11% of washing machine fires.

To check it: unplug the machine, pull it away from the wall, and remove the rear or lower access panel — the location varies by model, so search your model number plus “belt replacement” for the specific panel and belt part. You’re looking for a belt that’s shiny, cracked, frayed, or has left black rubber dust below it. Also turn the drum slowly by hand: it should rotate with smooth, even resistance. If the drum barely turns, look for the jam first — a sock or bra wire worked between the inner drum and outer tub will stall the drum and make even a healthy belt slip and burn. Replace the belt without clearing the jam and you’ll cook the new belt too.

A belt is typically one of the cheapest washer parts, and swapping one is a realistic first appliance repair on many machines.

Important caveat: many machines don’t have a belt at all. LG’s direct-drive front-loaders and many other modern designs couple the motor directly to the drum. If your machine is direct-drive and smells like burning rubber, skip to the gasket, hoses, and pump — and treat a persistent smell as motor/electrical territory.

Drain pump: the coin-and-chapstick trap

If the burning smell shows up while the machine is draining — often with a laboring hum — suspect the drain pump. Coins, hair pins, guitar picks, and chapstick tubes migrate out of pockets, through the tub, and into the pump, where they jam the impeller. A stalled pump motor overheats fast and smells like it.

On most front-loaders this is the easiest check in this guide: there’s a small access flap low on the front panel hiding a clean-out filter. Put down towels (a cup or two of trapped water will come out), unscrew the filter, and pull out whatever you find. On top-loaders the pump usually sits behind a rear or bottom panel and takes a bit more disassembly — still doable unplugged, but check a teardown guide for your model first. If the impeller is cracked or the pump still won’t turn freely once it’s clear, the pump needs replacing.

Door gasket rubbing (front-loaders only)

The gray rubber bellows around a front-loader’s door — the gasket, or boot seal — can get pushed out of position, or catch a small item like a baby sock or a rubber toy in its folds. Either way, rubber ends up dragging against a drum spinning at high speed, and you get a burnt-rubber smell plus, usually, visible black scuff marks on the gasket or the drum edge. LG’s troubleshooting for burning smells specifically says to check the gasket, filter, and tub for trapped debris and small rubber items.

Run your hand around the full circumference of the gasket, clear out anything trapped, and re-seat any section of the lip that’s folded or popped out of its channel. A gasket that’s torn or permanently deformed needs replacement — a moderate DIY job on some models, a technician job on others.

Overloading: the cause you fix by changing habits

Cramming the drum makes the motor and belt work at their limit for the whole cycle, and it’s not just bad for the machine’s lifespan — overloading appears in the NFPA’s washer fire data as a contributing factor in about 3% of fires. The working rule: clothes should fit loosely, and you should be able to turn the drum by hand with the load in it. On a top-loader, don’t pack laundry above the agitator; on a front-loader, leave roughly a hand’s width of space at the top of the drum. Your manual lists the actual rated capacity in pounds, and it’s worth the thirty seconds to look it up once.

Where DIY should stop: motor, wiring, capacitor, bearings

Being honest about this line is the whole point of this site. Here’s what I don’t open up, and why.

Electrical smells are a technician’s job

A sharp, acrid, burnt-plastic smell points at motor windings, the wiring harness, or the control board. Once wire insulation has overheated, the damage doesn’t heal — it’s a weak point that can short later even if the machine seems to run fine. Two specific traps for the DIY-inclined:

• The thermal protector fake-out. Washer motors have thermal cut-offs that kill power when the motor overheats. The machine “working again after it cools down” doesn’t mean the problem passed; it means the safety device is doing its job on repeat while the underlying jam or winding fault keeps cooking the motor.
• Capacitors hold a charge after unplugging. Some washer motors use a start capacitor, and a failing one can overheat and smell burnt. But a capacitor can bite you even with the machine unplugged, which is exactly why this one stays off my list.

If the breaker tripped at the same time you noticed the smell, that’s a short circuit announcing itself. Leave the power off and make the call. And if you’re seeing related symptoms at the outlet — sparks, discoloration, warmth — that’s an electrician rather than an appliance tech, per the NFPA’s guidance.

Tub bearing and spider arm: diagnosable by you, rarely fixable by you

If the burning smell arrived after weeks of a growing grinding, rumbling, or roaring noise during spin, the tub bearing is the prime suspect. A quick unplugged check: spin the empty drum by hand and listen — a rough, gravelly rotation or a drum that wobbles visibly on its axis points to the bearing, or on front-loaders to the spider arm, the three-armed bracket that carries the drum. (You’ll sometimes see “spider bearing” written online — there’s no such part. The spider and the bearing are separate components; either one failing lets the drum run untrue and rub where it shouldn’t.)

The reason this is pro territory isn’t the diagnosis, it’s the repair: on most front-loaders, replacing the bearing means tearing down the entire tub assembly. It’s one of the most labor-intensive washer repairs there is, and it’s frequently the repair quote that makes replacing the machine the smarter move — which brings us to the next section. Note that a wobbling drum has gentler causes too: a machine that rocks because it isn’t sitting level is a different, much cheaper problem, and it doesn’t produce burning smells by itself.

Front-loader vs. top-loader: what actually differs

• Drive system. Many modern front-loaders are direct-drive (no belt to slip); many top-loaders and some front-loaders are belt-drive. Your manual or a search on the model number settles which you have — and whether “check the belt” even applies.
• Door gasket. Only front-loaders have the big rubber boot seal, so gasket-rub smells are a front-loader problem by definition.
• Pump access. Front-loaders usually give you an easy clean-out filter behind a front flap; top-loaders generally make you remove a panel to reach the pump.
• Older top-loaders have extra friction parts in the drive train. On Whirlpool-family direct-drive top-loaders (Whirlpool, Kenmore, Maytag, Estate, Crosley, Roper), a failing motor coupler is a classic burnt-rubber source — Sears PartsDirect’s repair guide lists a burning rubber or plastic smell when the motor runs as a symptom of a worn coupler. Some of the same designs also use a brake assembly to stop the tub after spin, which repair technicians commonly cite as another friction-smell source when it drags. Both are technician jobs for most homeowners.
• Bearing repairs hit front-loaders harder. The sealed tub design makes the teardown longer, which is why bearing failure so often totals an older front-loader economically.

Repair or replace? Honest decision criteria

Consumer Reports puts the average washer lifespan at close to 10 years, and a long-standing rule of thumb reflected in CR’s repair-or-replace guidance is that spending 50% or more of the cost of a new machine on a repair is a poor bet. Layered onto what you now know about the causes, my honest read:

• Belt, drain pump, or gasket on a machine under 8 years old: repair, and it’s often a DIY repair. These are the cheap end of the parts catalog.
• Motor, control board, or tub bearing on a machine past 8 years: get the quote, but walk in expecting it to favor replacement. These repairs regularly land near half the cost of a new machine on their own.
• Any machine that actually produced flames or scorch damage: stop using it entirely, document everything for your insurer, and involve the manufacturer if it’s remotely recent — incident reports are how recalls like Samsung’s happen. You can also report the incident yourself at SaferProducts.gov.
• Anything under warranty: the manufacturer’s service line, every time. Opening the cabinet yourself can void coverage you’d otherwise get for free.

Preventing the next burning smell

Most of the failures above are wear, but a few habits genuinely shift the odds:

• Plug the washer directly into a wall outlet — never an extension cord. This is the U.S. Fire Administration’s flat rule for all major appliances; extension cords can overheat under a washer’s load. Their guidance is equally blunt about cords: if the cord is cracked, damaged, or loose, the card says to replace the appliance itself — not to patch the cord with tape.
• Stop overloading. See above — it strains the exact components (belt, motor) that produce burning smells when they fail.
• Empty pockets. Nearly everything that jams a drain pump walked in through a pocket.
• Run the tub-clean cycle and wipe the gasket monthly. LG recommends a tub clean roughly every 30 cycles; it’s mostly about mold and residue, but wiping the gasket folds is also when you’ll find the trapped sock before it drags on the drum.
• Keep the machine level. A washer that walks and slams during spin is adding vibration stress to the drum, bearing, and belt on every load.
• Register the appliance with the manufacturer. Unglamorous, but it’s how recall notices actually reach you instead of you finding out years later.

Key takeaways

• Smoke or a burning smell from a washer means stop the cycle and unplug it (or flip the breaker) immediately. Flames, or smoke that continues after power is cut, mean get out and call 911.
• Never restart a machine that has smoked or smelled strongly of burning. Aside from the new-hose fill test on a brand-new machine, every legitimate self-check happens with the machine unplugged.
• The smell narrows the cause: burnt rubber during spin points at the belt or gasket, burning during drain points at the pump, and a sharp electrical smell points at the motor, wiring, or control board.
• Belt, pump filter, gasket, and loading habits are homeowner territory. Motor windings, wiring, capacitors, and tub bearings are technician territory.
• A faint odor from a machine in its first 10–20 cycles is usually normal break-in per LG and GE; anything strong, smoky, or worsening is not — and a new machine is a warranty call, not a DIY project.
• Washer fires are real but rare (roughly 620 a year in the U.S. per NFPA), and they’re usually electrical — which is exactly why the electrical smells get the least DIY tolerance in this guide.

Frequently asked questions

Could the burning smell be the dryer, not the washer?

Genuinely worth checking — the machines usually sit side by side, and dryers account for 92% of laundry appliance fires, most often from lint. If both machines were running, shut both down, then check the dryer’s lint screen and vent for scorched lint before assuming the washer is the source.

The breaker tripped when the smell appeared. What does that mean?

A tripped breaker plus a burning smell almost always means a short circuit — the breaker did its job. Don’t reset it and try again. Leave the circuit off, unplug the washer if you safely can, and bring in an appliance technician (or an electrician, if the outlet itself shows sparking, warmth, or discoloration).

The machine still runs fine after the smell went away. Can I keep using it?

No — not until you’ve found the source. Friction and electrical faults are progressive: the belt that slipped once will slip worse under the next heavy load, and a motor being saved by its thermal cut-off is being damaged a little more each time. Do the unplugged checks above, and if they don’t turn up an obvious belt, pump, or gasket cause, that’s the signal to book a technician rather than to resume the laundry schedule.
