Full guide
What to check before you call
Safe observations first. Stop if anything involves smoke, gas, water near electricity, or a panel you would need to remove.
06 sections
A burning smell that is persistent, getting stronger, or smells electrical means stop using the appliance and leave it off. A faint odor during the first uses of a new appliance is the one case the manual may describe as normal; anything else needs diagnosis before the next cycle.
A burning smell from an appliance is hard to ignore. One symptom cannot single out a failed part, so begin with observations that are safe, can be repeated, and would be of use if you later set up an ASKO service visit.
Routine care is kept separate here from work that needs testing or disassembly. Never bypass a lock, a safety switch, or an error message in order to keep running the appliance. Short notes made now speed up the diagnosis and make it more accurate.
Start with the simple conditions
Shut the appliance off, keep everyone away from it, and isolate power only if that can be done without touching water, smoke, or a damaged connection. Leave the appliance in place and don’t force panels, fittings, or controls. If a small adjustment changes the outcome, run one normal cycle before reaching a conclusion.
Some new appliances give off a short-lived smell on first use. A smell that lingers, gets stronger, or seems electrical during ordinary use calls for a professional assessment. Check whether it occurs each time, with a specific load or setting, or after a stretch of running; that observation counts for more than restarting repeatedly.
| Circumstance | What to do | Don’t |
|---|---|---|
| Odor that persists | Stop using it | A further test cycle |
| Smoke in sight | Phone emergency services if needed | Opening panels |
| Smell on a new appliance | Follow the manual’s guidance | Disregarding a smell that worsens |
How can you tell what a burning smell means?
Describe it accurately. A dusty, baked-lint smell from a dryer points toward restricted airflow, while an electrical smell means stop and book a diagnosis.
Not every hot smell is an electrical one, and describing it accurately helps you decide what to do. A dusty or baked-lint smell from a dryer points toward restricted airflow or lint around the heating area. A smell of plastic or hot insulation that appears with a new appliance may be manufacturing residue burning off. A sharp, fishy, or acrid electrical smell, or any smoke, is a stop-and-isolate situation.
What matters is how the smell behaves: it fades after the first cycles, it tracks one program, or it grows each time you run the machine. A smell that grows is not a smell to wait out.
Safe checks that protect the appliance
Consult the manual that came with the appliance for model-specific controls, filter access, and care intervals. Clean only the parts labeled user-serviceable with the recommended products, and refit each removable piece exactly as intended.
Before testing again, clear any obstruction, lighten an unusually heavy load, and be sure airflow, water supply, and door clearance are unrestricted. Don’t reset again and again: doing so can hide an intermittent fault and leave water, heat, or pressure in places it doesn’t belong.
- Capture any message or error code on the display prior to clearing it.
- Look at visible hoses, vents, seals, and plugs while leaving electrical connections untouched.
- Keep to a single controlled test and avoid back-to-back tries.
Acceptable steps
- Stop running the appliance
- Let fresh air in if that is safe
- Set up a diagnosis
Technician’s job
- Searching inside while it has power
- Covering up the smell
- Carrying on with normal use
Can lint cause a burning smell in a dryer?
With a dryer, a burning smell can be tied to lint. The ASKO cleaning guide says to empty the lint filter after every load, and the dryer installation instructions for one vented model warn that excess duct length and bends impede drying performance. Poor airflow keeps heat in the drum area and lets lint build up where it should not.
Emptying the lint filter and looking at the accessible outdoor opening are fine user steps. If the smell remains after that, or the dryer shuts off hot, or the room smells of smoke, do not run another load.
Dishwashers and washers
For these, a hot smell during a cycle is not something a rinse or a cleaning cycle fixes. A musty or stale smell is a different complaint, usually about residue and moisture, and the cleaning guide treats it with interior and filter cleaning. Keep those two situations separate: stale means clean, burning means stop.
Know when the symptom needs diagnosis
When the basic checks leave the symptom unchanged, stay on the owner-serviceable side. Heating circuits and internal wiring, plus pumps, motors, and control boards, call for the right test equipment; refrigerant lines and gas connections do too, along with a technician who can verify the repair is safe.
Arrange service soon if performance declines, water leaks near electrical parts, a breaker trips, a hot or burnt smell shows, a new grinding noise starts, or a normal cycle can’t finish. An appliance with a safety warning should not stay in use.
What to tell the technician
Provide the model number, the precise symptom, when it started, the settings chosen, and what the safe checks above revealed. A picture of a code or a short description of a sound can assist too, but a cover must never come off to obtain it.
Watching closely never replaces a repair, though it is the right place to begin. Take care of the simple conditions, keep any error information that could help, and give electrical, gas, sealed-system, and internal mechanical jobs to a qualified ASKO technician.
Frequently asked questions
Is a burning smell from a new appliance normal?
Some new appliances give off a brief odor on first use, and the manual for your model is the place to confirm that. It should fade quickly. If it persists, intensifies, or is accompanied by smoke, stop using the appliance.
Can a full lint filter cause a burning smell in a dryer?
Lint buildup and restricted airflow can lead to hot, dusty smells, which is why the ASKO guide has you empty the filter after every load. A clean filter does not rule out other causes, so if the smell returns, book a diagnosis.
Should I open windows if I smell burning?
Ventilating is reasonable if it is safe to do so, but it is not a fix. Keep people and pets away, isolate power only if you can without touching anything wet or damaged, and do not restart the appliance.

Note the complete model number before buying parts, as board and sensor revisions can determine which part number is correct.
Resetting power once can clear a temporary fault; the same code returning again and again typically means something physical remains.
Keep vents and filters free of buildup between visits. Restricted airflow can look much like an electrical or sensor failure.
Stop using the appliance if you see water around it, smell something burning or notice sparks, and arrange for a professional to look at it.
