Breville BMO870BSS Combi Wave 3-in-1 Microwave Review 2026
Cluttered countertops drain creativity and stall dinner plans. Most kitchens juggle a microwave, an air fryer, and a small oven, each fighting for outlet space and cabinet storage.
The Breville BMO870BSS Combi Wave 3-in-1 promises to fold all three jobs into one brushed stainless box.
This review digs into real performance after months of hands-on testing, plus feedback from owners who’ve lived with it for years. You’ll learn how the inverter microwave, convection oven, and air fryer actually cook, where the unit stumbles, and whether the premium price tag holds up in 2026.
In a Nutshell
- Three appliances in one footprint: Combines a 1100-watt inverter microwave, a true convection oven, and a genuine air fryer using Breville’s Element iQ system, so one outlet replaces three gadgets.
- Smart presets remove guesswork: 19 built-in auto programs including Smart Cook, Smart Reheat, and Smart Defrost handle pizza, popcorn, frozen meals, and proteins without manual time entry.
- Soft-close door and quiet operation: The door closes itself silently, and Breville claims 50% quieter cooking than standard microwaves, which holds up in real kitchens.
- Air fry quality is genuinely crispy: Fries, wings, and frozen snacks brown evenly thanks to the 2.4 kW convection element and included air-fry rack and pan.
- Best for serious home cooks: Worth the spend if you bake, reheat, and air-fry often. Casual microwave users will find it overkill.
- Premium price, premium build: Around $450 to $500 in 2026, with brushed stainless steel housing and a 1-year warranty that some owners have stretched well past three years of daily use.

The Combi Wave is Breville’s flagship countertop multifunction oven. It packs a 1.1 cubic foot interior, a 1100-watt inverter microwave, 1700 watts of convection power, and a dedicated air-fry mode into a single 22-pound unit.
Breville positions it for busy households who want crispy texture without owning a separate air fryer. The interior is large enough for a 12-inch pizza or a small roast, yet the exterior footprint stays manageable on most counters.
The Element iQ system shifts heat between top, bottom, and convection elements based on the chosen program. This is the same technology Breville uses in its Smart Oven line, now adapted for microwave duties.
Key Features and Specifications
The control panel uses a clickable dial plus dedicated buttons for power, timer, and presets. No touchscreen, which owners actually prefer for cleaning.
Inside, you get a 12.5-inch glass turntable, a non-stick air-fry pan, and a wire rack for elevating food during convection cooking. The child-lock and mute function are welcome additions for families.
Key specs include 10 microwave power levels, a temperature range of 250°F to 450°F for convection, and a soft-close door that Breville claims is 80% quieter than typical slams. The interior light stays bright enough to monitor browning without opening the door.

Unboxing and First Impressions
The box arrives heavy, around 30 pounds with packaging. Breville uses molded foam and recycled cardboard, so setup feels premium without excessive plastic waste.
Inside, you’ll find the unit, a crumb tray, air-fry basket, wire rack, a quick-start guide, and a full recipe book. The brushed stainless finish resists fingerprints better than glossy alternatives.
First impression: this thing is solid. The door closes with a satisfying hush rather than a clatter. The dial spins with weighted resistance, and the buttons click with confidence rather than mushiness.
Performance: How It Actually Cooks
The inverter microwave is the standout. Reheated rice stays fluffy instead of rubbery, melted butter doesn’t explode, and chocolate tempers without scorching. This alone justifies a chunk of the price.
Air-fry performance impresses on frozen fries, wings, and breaded items. A pound of fries crisps in roughly 18 minutes with a single shake. Fresh-cut potatoes need a light oil toss to match results from a basket-style air fryer.
Convection baking handles cookies, small pizzas, and reheated leftovers beautifully. The cavity isn’t deep enough for a full chicken, but a 4-pound spatchcocked bird roasts to crisp-skinned glory in about 50 minutes.
Smart Presets and Ease of Use
The 19 smart presets cover pizza, popcorn, vegetables, fish, and reheating common leftovers. Each preset asks for weight or portion size, then calculates time automatically.
Smart Reheat is the program owners use most. Drop a plate of leftovers in, hit the button, and the unit detects moisture to stop cooking before food dries out.
There’s a real learning curve, though. The manual is dense, and unlocking the convection-microwave combo cooking takes a few menu dives. Expect a two-week familiarity period before muscle memory kicks in.
Build Quality and Design
The brushed stainless exterior matches most modern kitchens and hides smudges well. Inside, the cavity is enameled steel with a removable glass plate that cleans in the dishwasher.
The soft-close door is genuinely quieter than rivals. Late-night reheats no longer wake sleeping kids or partners. This single feature converts skeptics in showrooms.
Weight and size deserve mention. At 22 pounds and roughly 21 inches wide, it eats real counter estate. Measure your space before ordering, and leave the required 20 cm clearance on the sides and top for ventilation.
Real Customer Feedback in 2026
Long-term owners on Reddit, Amazon, and appliance forums report 3 to 4 years of trouble-free use as common. The inverter draws particular praise for melting chocolate and softening butter without hot spots.
The most repeated complaint involves service costs after warranty. One owner reported a $200 part plus $150 labor repair when the magnetron failed at year four. Breville’s repair network is thinner than mainstream brands.
Buyers who use it primarily as a microwave often regret the spend. The phrase “I only use the microwave” appears in multiple reviews, suggesting light cooks should choose a cheaper inverter unit.
Downsides and Who Should Skip It
Defrost performance tested as mediocre in independent lab tests, particularly for a pound of frozen ground beef. Edges cook while centers stay icy without manual intervention.
The unit is not for small kitchens or apartments with limited counter depth. It also isn’t ideal for budget shoppers, since competing 4-in-1 units from Panasonic and Toshiba cost half as much with respectable results.
Skip this if you bake bread weekly. The cavity is too small for standard loaf pans, and the convection element runs slightly hotter than dial settings indicate. Adjust temperatures down by 15 to 25 degrees until you calibrate by feel.
Cleaning and Maintenance
The enamel interior wipes clean with a damp microfiber and mild soap. Avoid abrasive pads, which dull the finish over time.
The air-fry pan and rack go in the dishwasher, though hand-washing extends the non-stick coating’s life. Crumbs collect under the turntable, so a weekly lift-and-wipe keeps odors away.
Grease splatter from air frying is the only nuisance. Cooking bacon or wings uncovered will speckle the ceiling of the cavity, requiring a degreaser every few weeks. A parchment lining on the pan reduces this dramatically.
Pricing and Value in 2026
The Combi Wave sits between $450 and $500 in 2026, occasionally dipping to $399 during Prime Day or Black Friday. Refurbished units appear around $320 with the same 1-year warranty.
Value depends entirely on use case. Replacing a $150 microwave, a $120 air fryer, and a $200 toaster oven makes the math work. Counter space saved is worth real money in small kitchens.
For heavy users, the cost-per-meal over 4 years sits below 15 cents. That’s reasonable for an appliance touched multiple times daily. Light users won’t recoup the premium.
Final Verdict
The Breville BMO870BSS Combi Wave 3-in-1 earns its premium status through thoughtful engineering, quiet operation, and genuinely useful three-in-one cooking. The inverter microwave alone outperforms most standalone units, and the air fry and convection modes turn out crispy, evenly browned food.
It’s not flawless. Defrost results disappoint, repair costs sting, and casual cooks won’t use enough features to justify the spend. But for home cooks who reheat, bake, and air fry regularly, this is the most capable countertop unit available in 2026.
Recommended for: serious home cooks, small households consolidating gadgets, and anyone tired of noisy microwave doors.
Expert FAQs
Is the Breville Combi Wave worth the high price?
For households that genuinely use all three functions, yes. Replacing a microwave, air fryer, and small convection oven recovers most of the cost, and build quality outlasts cheaper rivals by years.
Can it replace a full-size oven?
No. The 1.1 cubic foot cavity handles a 12-inch pizza or small roast, but full sheet pans, large casseroles, and bread loaves won’t fit. Treat it as a supplement, not a replacement.
How loud is the Combi Wave during operation?
Notably quieter than standard microwaves. The soft-close door and insulated cavity reduce hum and vibration. Late-night use rarely wakes light sleepers in adjacent rooms.
Does the air fryer actually crisp food?
Yes, especially frozen foods and breaded items. Fresh-cut fries need a light oil coating to match basket-style air fryers, but wings, nuggets, and tots come out genuinely crisp.
How long does the Combi Wave last?
Owner reports consistently show 3 to 5 years of daily use before any issues. Breville’s 1-year warranty is shorter than some rivals, and out-of-warranty repairs run $200 to $400.
Is it safe for kids to use?
The child-lock function prevents accidental starts, and the soft-close door avoids pinched fingers. The exterior gets warm during convection cooking, so supervise younger children near the unit.
Can I cook microwave and convection at the same time?
Yes. The Combi Cook mode runs both functions simultaneously for faster results on items like baked potatoes, lasagna, and casseroles. It cuts cooking time roughly in half versus convection alone.
How does it compare to the Panasonic HomeChef?
The Panasonic costs less and offers solid air frying, but feels less premium and runs louder. The Breville wins on build quality, quiet operation, and convection accuracy. Panasonic wins on price and availability.
