Yes, for most Cosori models the removable basket and crisper plate are dishwasher safe. Cosori labels them that way in its manuals and on its product pages. The main unit, the part with the heating element, fan, cord, and control panel, is never dishwasher safe and should never be submerged in water.
That's the short answer. The longer answer matters, because "dishwasher safe" and "will still look good in two years" aren't quite the same thing. Below I'll go through which parts are cleared for the machine, which ones aren't, how dishwasher cycles wear down the nonstick surface, and how the answer shifts if you own an air fryer toaster oven instead of a basket-style model.
What Cosori Means When It Says a Part Is Dishwasher Safe
The dishwasher-safe rating covers the removable, food-contact parts. On a basket-style Cosori, that's the outer basket and the crisper plate that sits inside it. Both are coated with a PFOA-free nonstick surface, and both are built to survive detergent and hot water without warping or delaminating.
What the rating doesn't promise is that the coating will look factory-fresh after 300 cycles. Dishwasher detergent is alkaline and abrasive by design. It's formulated to strip baked-on food from ceramic and stainless steel, and nonstick coatings sit at the softer end of what it's cleaning.
So the part is safe. The finish just ages faster.
Cosori's own manuals thread that needle by listing the basket as dishwasher safe while also recommending hand washing. Both statements are true at once. You can use the machine, and the manufacturer would prefer you didn't.
If you want the official wording for your exact model, the manual PDF for it is on Cosori's site.
The Parts You Can Put in the Dishwasher
On the popular basket models, the Lite, Pro LE, Dual Blaze, and TurboBlaze lines included, two pieces come out:
- The frying basket (the drawer itself)
- The crisper plate (the perforated insert with the little feet)
Both are dishwasher safe. Put them on the top rack if they fit. Larger 5.8-quart and 6.8-quart baskets often won't clear a top rack, and that's the moment most people give up and wash by hand anyway.
Accessory kits sold for Cosori fryers, skewer racks, cake pans, pizza pans, silicone liners, are usually dishwasher safe too, but check the packaging. Silicone and stainless handle detergent well. Anodized aluminum sometimes doesn't, and it can dull or discolor.
The Parts That Must Stay Out of the Water
The main housing never goes in the dishwasher and never gets submerged. Inside it you've got a heating coil, a fan motor, wiring, and a control board. Water in any of those is a shock or fire risk, and it voids the warranty instantly.
Same rule for the power cord and plug. Wipe the exterior with a damp cloth, dry it, done.
The interior chamber, the cavity above the basket where the heating element sits, gets cleaned by hand as well. Unplug the unit, let it cool completely, then wipe the element and the chamber ceiling with a damp cloth or a soft brush. Grease spatters up there and eventually smokes if you ignore it.
A soft-bristle brush works better than a scrubber because you don't want to bend the coil.
Why the Nonstick Coating Is the Real Limiting Factor
Ask why hand washing is recommended and it comes back to the coating every time. Three things in a dishwasher cycle work against nonstick:
Detergent chemistry. Powder and pod detergents contain enzymes and alkaline salts that etch soft surfaces over time. Liquid detergents are usually gentler.
Heat. A heated dry cycle can push interior temps well above what a rinse cycle hits. Repeated heat cycling makes coatings brittle at the edges, which is where chipping usually starts.
Contact. Baskets rattle against racks and other dishes. Metal-on-nonstick contact leaves scratches, and a scratch is where a coating begins to peel.
None of this destroys a basket overnight. But the difference between a hand-washed Cosori basket and a daily-dishwashered one shows up clearly after a year or two, usually as dull patches near the corners and food starting to stick where it never did before.
Running a Cosori Basket Through the Dishwasher Without Trashing It
If you're going to use the machine, and plenty of people do, a few habits cut the wear down a lot.
- Soak first. Fill the basket with warm water and a drop of dish soap for 10 to 15 minutes. Softened grease comes off in the wash instead of getting baked on by the dry cycle.
- Use the top rack when it fits. Lower racks sit closer to the heating element in many dishwashers, and the spray pressure is higher down there.
- Skip the heated dry. Choose air dry, or pull the basket out at the end of the rinse and towel it.
- Use liquid detergent over pods when you can. Pods pack a stronger dose of alkaline cleaner into one release.
- Don't crowd it. Give the basket space so nothing knocks against the coating during the cycle.
- Dry it completely before reassembling. Trapped moisture between the crisper plate and basket floor encourages odor.
One caveat worth stating plainly: if your basket is already scratched or the coating has started flaking, stop putting it in the dishwasher. Detergent gets under a lifted edge and accelerates the peel. At that point you're better off replacing the basket, which Cosori sells separately for most current models.
Hand Washing, and Why It Takes Less Time Than You'd Think
Hand washing a Cosori basket is a two-minute job if you do it while the unit is still warm. Warm grease wipes; cold grease scrapes.
Let the basket cool enough to touch, then wash with warm soapy water and a soft sponge or a nylon brush. No steel wool, no scouring pads, no abrasive powders. For stuck-on residue, a paste of baking soda and water left for 10 minutes lifts most of it without scratching.
For burnt-on spots along the basket seams, a soft toothbrush gets into the corners better than a sponge. Rinse well, since detergent film left behind can smoke on the next cook.
The crisper plate is the fiddly part. Food wedges into the perforations and the plate's little feet. Soaking handles almost all of it.
Push a soft brush through the holes from the underside rather than picking at the top.
How the Answer Changes by Cosori Model
The question of whether a Cosori air fryer is dishwasher safe has slightly different answers depending on which shape you own.
Basket models (Lite 4.0-Qt, Pro LE 5.0-Qt, Dual Blaze 6.8-Qt, TurboBlaze 6.0-Qt and similar): basket and crisper plate are dishwasher safe. Straightforward.
Dual-basket models: same rule, doubled. Both drawers and both crisper plates come out. Worth noting that two baskets take up serious dishwasher real estate, so most owners with these end up hand washing at least one.
Air fryer toaster ovens (the countertop oven-style units with a door): these come with a food tray, a fry basket, a wire rack, a crumb tray, and sometimes a rotisserie fork set. The removable trays and racks are generally dishwasher safe. The crumb tray usually is too.
The oven cavity itself is wiped by hand, and the rotisserie shaft and forks are typically stainless, which handles the dishwasher fine.
Rotisserie and accessory pieces: check each one. Stainless goes in. Coated pans are usually fine but wear the same way baskets do.
If your model isn't listed here, the manual settles it. Cosori prints the dishwasher-safe icon in the care section for every unit, and the manuals are downloadable by model number, which is on the sticker underneath the base.
Mistakes That Shorten the Life of a Cosori Basket
A few habits do more damage than the dishwasher ever will:
- Dunking a hot basket in cold water. Thermal shock warps metal and cracks coatings. Let it cool first.
- Using metal utensils inside the basket. Tongs and forks scratch the surface. Silicone or wooden tools only.
- Aerosol cooking sprays. Many contain propellants and lecithin that polymerize into a sticky, brown film nonstick coatings can't shed. Brush on oil instead.
- Scrubbing with steel wool or a green scouring pad. This is the fastest way to ruin a basket, and it's not covered by warranty.
- Leaving grease to sit for days. Old grease bakes harder each time you cook, and eventually you need aggressive scrubbing to remove it.
- Cleaning the interior with the unit plugged in. Unplug it. Always.

A Note on Safety Recalls
Worth knowing if you own an older unit: in early 2023, Cosori recalled roughly 2 million air fryers in the US and Canada over a wiring issue that could overheat. If you bought a Cosori before that date and never checked, look up your model on the U.S. Consumer Product Safety Commission site.
It has nothing to do with cleaning, but it's the kind of thing people miss.
Frequently Asked Questions
Can I put the Cosori crisper plate in the dishwasher?
Yes. The crisper plate carries the same dishwasher-safe rating as the basket on Cosori's basket-style models. Soaking it in warm soapy water first is worth the extra ten minutes, because dishwasher spray often doesn't clear food from the perforations on its own.
Does putting the basket in the dishwasher void the Cosori warranty?
No. Cosori lists the basket and crisper plate as dishwasher safe, so normal machine washing doesn't void anything. Damage from abrasive scrubbers, metal utensils, or submerging the main unit is a different story, and that kind of damage generally isn't covered.
Is it true that the dishwasher ruins nonstick air fryer baskets?
It doesn't ruin them, but it does age them faster than hand washing. Alkaline detergents and heated dry cycles slowly dull and weaken nonstick coatings. A basket washed by hand will typically keep its release properties longer than one that goes through the machine several times a week.
Can I put the whole Cosori air fryer in the sink?
No. Only the basket, crisper plate, and any removable racks or trays touch water. The main body holds the heating element, fan, and electronics, and submerging it creates a shock and fire risk plus a dead appliance.
How often should I clean the basket?
After every use. Grease left in the basket bakes on harder with each cook, and it eventually smokes. The heating chamber above the basket needs attention less often, roughly every few weeks with regular use, or sooner if you cook a lot of bacon or fatty cuts.
What if the nonstick coating is already peeling?
Stop using the dishwasher on it and replace the basket. Cosori sells replacement baskets and crisper plates for most current models. A flaking coating won't release food properly, and detergent will lift more of it every cycle.
Worth Remembering
Cosori baskets and crisper plates are dishwasher safe, and using the machine occasionally won't hurt anything. Daily dishwasher trips will visibly wear the coating over a couple of years, and a warm-water hand wash takes about as long as loading the rack anyway. The only hard rule is the one about the main unit: damp cloth, never water.
