Steam ovens, combi ovens and steam air fryers aren't the same thing
A built-in steam oven in a kitchen renovation costs thousands and gets plumbed or filled from a big tank. On Amazon AU, the countertop versions come in three shapes, and they don't do the same job. There are combi steam ovens, which are small convection ovens with a water reservoir and a steam function. There are microwave combis that add steam to a microwave, grill and oven. And there are steam air fryers, which are air fryers with a small water tank that puffs steam into the basket.
Two of the six picks are ovens and four are air fryers. The Cuisinart Gourmet Pro is a 20L combi oven with steam, air fry and convection, and the Panasonic NN-DS59 is a 27L microwave that also steams, grills and bakes. The Philips 5000 Series, the two Sunbeams and the Dreame AF30 are air fryers with steam modes. I've put them on one page because Amazon AU has so few countertop steam ovens that most people searching for one end up choosing between these.
The difference that matters is the cavity. An oven has a door, a flat tray and enough height for a roasting dish or a loaf tin, so it can bake, roast and steam a tray of vegetables at once. An air fryer has a drawer with a basket, which is great for crisping but limits you to what fits in the basket. If you want to bake, an oven shape is the one to buy. If you mostly want crispy chicken that isn't dried out, a steam air fryer usually does it with less fuss.
The listings for all six are full of claims about what steam does to the food, and I've left those out. What I can tell you is how the hardware works, where the water goes, what fails and what each one asks of your power point, which is what decides whether one of these is still working in three years. Our benchtop oven guide covers the dry convection ovens if you don't need steam at all.
What the steam actually does
Steam carries heat into food faster than dry air at the same temperature, and it stops the surface drying out while the inside cooks. That's why a steam oven can reheat leftovers without turning them to cardboard and why a steam air fryer can cook a whole chicken that's crisp outside and still moist. Pure steam cooks at around 100 degrees, while the combination modes mix steam with fan heat at higher temperatures so the outside still browns.
The Cuisinart lists a range of 40 to 230 degrees with a 1L water reservoir, and the Dreame lists 50 to 200 degrees. The Philips, Sunbeam and Panasonic listings don't give their steam temperatures or water tank sizes, so check the manual on the maker's site before you buy if those matter to you. A small tank on an air fryer is fine for a 20 minute cook, but a long roast with steam may need a top up partway through.
Steam also cleans. The Philips, both Sunbeams and the Panasonic list a steam cleaning programme, which softens baked-on grease so it wipes off instead of needing a scourer. That's a genuine plus, because grease left on heating elements and fan guards bakes into a hard layer that smokes and smells, and it's one of the reasons air fryers end up in the bin. Running the steam clean after greasy cooks keeps the element clean far longer.
Scale is what kills steam appliances
Every steam appliance boils water, and boiling water leaves its minerals behind as scale, the same white crust you see inside a kettle. In a steam oven or steam air fryer, scale builds up in the small boiler or heating plate that makes the steam and in the narrow tubes and nozzle that carry it. Once it builds up, the steam comes out weaker, the element runs hotter than it should, and eventually the pump or nozzle blocks and the steam mode stops working altogether.
How fast that happens depends mostly on your water. Hard water areas scale an appliance in months, while soft rainwater or filtered water can take years. If your tap water leaves white marks on the shower screen, it'll scale a steam oven too. Filtered water from a jug is the easy fix, and our filter jug guide covers the ones that reduce scale. Distilled water works as well, though check the manual, since some makers want a little mineral content for their sensors.
Descale on a schedule rather than waiting for a fault. Most makers use a citric acid or vinegar solution run through a descale programme, and the manual says how often for your water. Don't use a strong acid or a bathroom descaler, since they can attack seals and the coating inside the boiler. If the steam has already slowed to a trickle, a couple of descale cycles back to back often brings it back, but a boiler that's completely blocked usually means a service call.
Empty the water tank after each use and leave its lid open to dry. Water left sitting in a warm tank grows a slimy film within a few days, and that film ends up in the steam lines. It's also why a steam appliance that's been stored with water in it can smell musty the next time you turn it on. Rinse the tank, dry it and put it back empty, and the steam system stays clean between descales.
Water, door seals and where the steam goes
Steam has to go somewhere, and in a countertop appliance it comes out of a vent, usually at the back or the top. Under overhead cupboards, that steam condenses on the underside of the cupboard every time you cook, and particleboard cupboards swell and peel after a year or two of it. Leave clear space above the vent, as the manual specifies, or pull the appliance forward to cook. The same goes for the wall behind it, where steam can lift paint and wallpaper.
The door seal on a combi oven is a wear part. It keeps the steam inside the cavity, and once it hardens, cracks or gets a nick from a baking tray, steam leaks out round the door and runs down the front of the oven. Wipe the seal after cooking, keep fat and food off it and look at it now and then for splits. A leaking seal also lets condensation drip onto the control panel below, which is a fault I'd sort out before it gets into the electronics.
Steam vents and phones don't mix either. A phone left charging on the counter beside a steam vent pulls in humid air every time it warms and cools, and that moisture condenses on the board inside, the same slow corrosion we find in phones kept in steamy bathrooms. Keep phones and tablets well clear of the vent. If one has started acting up after living next to the oven, our water damage guide explains what's happening inside it.
Power draw and the 10A socket
These appliances all heat with electric elements, and heating is the biggest draw in any kitchen appliance. The Cuisinart lists 1,875W and the Dreame 2,300W, which sits just under the 2,400W a standard Australian 10A socket is rated for. The Panasonic's 1,000W figure is its microwave output, not what it draws from the wall, and the Philips and Sunbeam listings don't give a wattage. The rating plate on the back is the real figure, so read it when the appliance arrives.
At the Australian average tariff of roughly 33c per kWh, a 1,875W oven costs about 62c an hour running flat out, and the 2,300W Dreame about 76c. In practice the element cycles on and off once it's up to temperature, so a typical 30 minute cook costs less than half of that hourly figure. That's usually less than heating a full size wall oven for the same tray of food, which is where a countertop unit earns its spot.
Plug each one straight into a wall socket, not into a powerboard shared with a kettle or toaster. Two heating appliances on one powerboard can pull more than 10A between them, and a powerboard running at its limit warms up at the plug and the switch. Don't use an extension lead either, especially a thin one. If the plug or socket ever feels warm after a cook, stop using that socket and get it looked at, because a loose socket contact is a common cause of scorched plugs.
Microwave combis are the one you never open
The Panasonic NN-DS59 is a microwave as well as a steam oven, and that changes the repair picture. A microwave contains a high voltage capacitor that can hold a dangerous charge even after it's unplugged, so it isn't something to open up at home, however simple the fault looks. A door that won't latch, a turntable motor or a blown fuse can all be fixed, but it's a job for a qualified appliance technician, not a screwdriver and a YouTube video.
The parts you can look after are the door, the seals and the inside. Keep the door edges and the cavity face clean, since food left there stops the door sealing and can cause arcing. Wipe up steam condensation after each steam cook, because water left in the cavity rusts the edges of the paint over time. The Panasonic is a flat-bed design with no turntable, which leaves one less part to break and makes the floor of the cavity easy to wipe.
If a microwave sparks, makes a buzzing or grinding noise it didn't used to make, or keeps running with the door open, stop using it and unplug it. Those faults can point to a damaged waveguide cover, a failing magnetron or a door interlock problem, and the interlock is the part that matters most. Our microwave guide covers what to look for if the combi features aren't worth it to you.
Size, capacity and counter space
Capacity numbers aren't comparable across the shapes. The Cuisinart is a 20L oven and the Panasonic a 27L microwave cavity, measured as the inside of a box. The air fryers are measured by basket: 7.2L for the Philips, 7L for the Sunbeam SteamFry and the Dreame, and 11L for the Sunbeam Multi Zone, which splits into two 5.5L zones. A 7L basket fits a whole chicken by the Sunbeam SteamFry's listing, while the Cuisinart's listing describes a tray, a rack and a basket inside the oven.
Measure the counter before you order. The Cuisinart lists its outside size as 41 by 39 by 37.5cm and the Philips as about 46 by 40 by 32cm, and the others don't give outside dimensions in their feature text. Allow space at the sides and above for the vents, plus room to open a door or pull out a drawer. A drawer air fryer needs clear space in front of it, while an oven door needs space to drop down and a bit of counter to put a hot tray on.
Think about where the water tank sits, too. A tank that slides out from the side or the back is easy to fill if the appliance is pulled forward, but awkward if it's tucked into a corner. Most of the listings don't say where the tank goes, so look at the product photos or the manual before deciding where the appliance will live. A tank you can't reach easily is a tank that gets left full, and that's where the scale and the slime start.
How I picked these six
I looked at every countertop steam oven, combi oven and steam air fryer sold new on Amazon AU between about $150 and $1,500. I left out a Cuisinart combi oven whose listing describes no steam function at all, a Philips dual basket listing whose title and model code didn't match, and the sellers I couldn't confirm as Australian retailers. Then I picked six from what was left, all sold by Amazon AU or Cuisinart's Australian store.
The two ovens come first because they're the closest thing to a steam oven on Amazon AU. The four air fryers are ordered by Amazon AU sales rank in the Air Fryers category on the day: the Philips at #36, the two Sunbeams sharing #38 on a grouped listing and the Dreame at #56. The Cuisinart sits at #105 in Air Fryers and the Panasonic at #52 in Microwaves, so their ranks aren't directly comparable with the others.
Where a listing doesn't give a figure, the card says so rather than guessing, and the Cuisinart's listing carries a 17L size field against the 20L in its title and features, which I've noted on its card. Prices move week to week, and small kitchen appliances move a lot before Christmas, so check the price and what's in the box on the day you order. If you just want crisp food without steam, our air fryer picks cover the plain models.

Cuisinart Gourmet Pro Multifunctional Combi Steam Oven CSO-500NXA, 20L, Stainless Steel
ASIN B0FRF7QM6B • $448 • Sold by Cuisinart AU on Amazon AU
This is the closest thing to a real steam oven you'll find on Amazon AU, and it's the one I'd start with if steaming is the point. Cuisinart's Australian store sells it for $448. It's a 20L countertop oven with steam, air fry and convection modes in one cavity, a 1L water reservoir and a temperature range of 40 to 230 degrees. The listing gives 1,875W, 20 auto presets and 11 programs on a touch screen, and an outside size of 41 by 39 by 37.5cm. The model code is CSO-500NXA, and it ranks #105 in Amazon AU's Air Fryers category, which is where Amazon has filed it. The touch screen sits on the front, so it's easy to reach even when the oven is pushed back under a cupboard.
The oven shape is what sets it apart from the four air fryers. It comes with a stainless steel baking tray, an oven rack and a cooking basket, so it can roast on the tray, steam a tray of vegetables or air fry in the basket, and the door gives you room for a loaf tin or a small casserole dish. Cuisinart states a 3 year warranty on the listing, the longest stated of the six, which matters on a steam appliance because the steam system is the part most likely to fail. The 1L tank is a sensible size for a countertop unit. It's enough for a long steam roast without stopping to refill halfway through, which the smaller air fryer tanks can't always manage.
The listing's size field says 17L while the title and features say 20L, so I'd treat 20L as the cavity and check the manual. At 1,875W it wants its own wall socket. Use filtered water in the reservoir, empty it after each cook and leave it open to dry, and run the descale programme as the manual sets out. Wipe the door seal after steam cooks, and leave clear space above the vents under overhead cupboards so the steam doesn't swell them. Wipe the cavity dry after steaming so the paint doesn't rust at the edges.
Honest caveats: The listing's size field says 17L against 20L in the title and features. It ranks #105 in Air Fryers, well below the steam air fryers. At 1,875W it needs its own wall socket, and the listing doesn't give the steam temperature or how often to descale.
Best for: Cooks who want a true countertop steam oven that can also bake, roast and air fry.
Price: $448 (Cuisinart AU) • Model: CSO-500NXA • Type: Combi oven: steam, air fry, convection • Capacity: 20L stated (size field says 17L) • Water tank: 1L reservoir • Power: 1,875W stated • Temperature: 40 to 230 degrees • Warranty: 3 years stated • Rank: #105 in Air Fryers (Amazon AU)

Panasonic NN-DS59 27L 4-in-1 Flat-Bed Combination Microwave Oven with Steam
ASIN B0BM39DXS3 • $824 • Ships from Amazon AU
The Panasonic is the pick for a kitchen that wants a steam oven and a microwave in one footprint. Amazon AU sells it for $824, the most expensive of the six, and it ranks #52 in Amazon AU's Microwaves category. It's a 27L flat-bed combination microwave, which means no turntable, with steam, grill and bake functions on top of the microwave, and the listing gives 1,000W as its microwave output. The model code is NN-DS59NBQPQ in black, and the listing states an Australian plug and an Australian manufacturer's warranty, with the warranty field giving 1 year. An Australian plug stated in the listing is exactly what I look for on any appliance sold through a big marketplace.
Its party piece is the grill tray. Microwave power heats the bottom of the tray while the grill works from the top, so chicken and chips crisp on both sides without turning, and fat runs off down the grooves. You can also steam from the top for vegetables, and the listing describes steam cleaning programmes for the stainless steel interior. A flat-bed cavity is easier to clean than a turntable model and fits a wider dish, and the grill tray is listed as dishwasher safe, which helps after a greasy cook. The steam function sits alongside the normal microwave controls, so it's easy to steam a bowl of vegetables while something else waits on the counter, and it frees up the counter space a separate microwave would take.
It's a microwave, so the high voltage parts inside mean it should never be opened at home, and any repair is a job for an appliance technician. The listing doesn't give the water tank size or the oven's power draw from the wall, so read the rating plate when it arrives and give it its own socket. Keep the door edges clean so it seals, wipe out condensation after steaming and empty the water tank after each use. Descale it with the method in the manual. If it ever sparks or buzzes, unplug it straight away.
Honest caveats: It's the most expensive of the six and ranks #52 in Microwaves with a low overall rank. The 1,000W figure is microwave output, not wall draw, and the listing doesn't give the water tank size. Microwave repairs need a technician, so it isn't one to open up yourself.
Best for: Kitchens that want steam, grill and bake in the same space as the microwave.
Price: $824 (Amazon AU) • Model: NN-DS59NBQPQ • Type: Microwave combi: steam, grill, bake • Capacity: 27L, flat-bed, no turntable • Power: 1,000W microwave output stated • Plug: Australian plug stated • Cleaning: Steam cleaning programmes • Warranty: 1 year, Australian manufacturer's • Rank: #52 in Microwaves (Amazon AU)

Philips Air Fryer 5000 Series with Steam, 7.2L NA547/07
ASIN B0G26BH1PF • $348 • Ships from Amazon AU
If you want a steam air fryer rather than an oven, the Philips is where I'd start, since it's the best-ranked of the six on Amazon AU at #36 in Air Fryers and #7,297 overall. Amazon AU sells it for $348. It's a single 7.2L basket air fryer with a SteamFry mode that combines steam and air frying, plus 21 cooking options by the listing, Philips' RapidAir Plus air flow, a ceramic coated basket and a viewing window so you can check the food without opening the drawer. The model code is NA547/07, and the listing gives its size as about 46 by 40 by 32cm. That's a fair chunk of counter, so measure first.
The automatic SteamClean function is the feature I'd buy it for. It uses steam to soften fat build-up in the basket and around the heating element, and grease baked onto the element is what makes most air fryers smoke and smell after a year or so. The listing also mentions shake reminders through Philips' HomeID app. Philips states a 2 year warranty on the listing, while the Sunbeams and the Dreame don't state one. A viewing window is a small thing that saves a lot of drawer pulling, and every pull lets heat and steam out. The ceramic coated basket wipes clean easily as long as you keep the scourer away from it.
The listing doesn't give a wattage or the water tank size, so check the rating plate and the manual. A 7.2L single basket cooks one thing at a time, so it suits a couple or a small family better than a big one. Use filtered water, empty the tank after cooking, and descale as the manual says. Wash the ceramic basket by hand or gently, since scourers wear the coating, and keep the vent clear of overhead cupboards and phones on the counter. Give it its own wall socket rather than a powerboard.
Honest caveats: The listing doesn't state the wattage or water tank size. It's a single basket, so it cooks one dish at a time. The ceramic coating needs gentle cleaning to last, and the shake reminders need the HomeID app. At about 46cm deep it takes a fair bit of counter.
Best for: Couples and small families who want the best-ranked steam air fryer with an easy clean.
Price: $348 (Amazon AU) • Model: NA547/07 • Type: Steam air fryer, single basket • Capacity: 7.2L • Size: About 46 x 40 x 32cm stated • Cleaning: Automatic SteamClean • Extras: Viewing window, HomeID app • Warranty: 2 years stated • Rank: #36 in Air Fryers (Amazon AU)

Sunbeam Multi Zone Steam Air Fryer AFP6100BK, 2 x 5.5L or 11L
ASIN B0HGMZ73R3 • $399 • Ships from Amazon AU
The Sunbeam Multi Zone is the steam air fryer for a bigger household. Amazon AU sells it for $399, and it ranks #38 in Air Fryers, a rank shared with the smaller Sunbeam SteamFry on a grouped listing. Its removable centre wall turns one wide drawer into two independent 5.5L zones or one 11L zone, the biggest basket capacity of the six, and the listing says it cooks for up to 6 people. Match and Sync functions coordinate settings and finish times across the two zones. The model code is AFP6100BK in black. For a family that roasts on a Sunday and air fries chips through the week, it's the most flexible of the four air fryers, and the shared drawer means one thing to empty and clean at the end of the night.
It lists eight functions: air fry, steam fry, turbo crisp, steam, bake, grill, roast and reheat, and it comes with 11 accessories, which is more kit than the other picks list. The steam clean function softens grease so it wipes off, which matters on a big drawer that'll see a lot of roasts. Two zones are useful when the main and the vegetables need different settings, and Sync means both finish together instead of one going cold. Sunbeam is a long established brand in Australia, so parts and accessories tend to be easy to find. A drawer this wide is heavy when it's full, so pull it out with both hands.
The listing doesn't give a wattage, a water tank size or a warranty, so check the box and the manual. A wide drawer needs counter space in front of it, and two heating zones can draw a lot, so give it its own wall socket rather than a powerboard. Use filtered water, empty the tank after each cook, and descale as the manual sets out. Wash the accessories after use, since grease left on them bakes on, and keep the vent clear of overhead cupboards. Take the centre wall out to clean behind it now and then.
Honest caveats: The listing doesn't state the wattage, water tank size or warranty. The rank is shared with the smaller Sunbeam SteamFry, so it isn't this model's own figure. It's a wide unit that needs counter space and a wall socket of its own.
Best for: Families who want two steam air fryer zones that finish at the same time.
Price: $399 (Amazon AU) • Model: AFP6100BK • Type: Steam air fryer, dual or single zone • Capacity: 2 x 5.5L or 1 x 11L • Functions: 8, incl. steam and steam fry • In the box: 11 accessories • Cleaning: Steam clean • Warranty: Not stated on the listing • Rank: #38 in Air Fryers (Amazon AU), listing shared

Sunbeam SteamFry Air Fryer + Steam AFP4600BK, 7L
ASIN B0CN596PYS • $174 • Ships from Amazon AU
The Sunbeam SteamFry is the way into steam air frying for the least outlay of the six, at $174 from Amazon AU. It shares the #38 rank in Air Fryers with the Multi Zone on a grouped listing. It's a single 7L drawer air fryer with six functions: air fry, SteamFry, steam, roast, grill and reheat, plus six air fry presets for fries, steak, chicken, drumsticks, fish and vegetables. The listing says the 7L space fits a whole chicken or a big batch of fries. The model code is AFP4600BK, and the controls are a digital touch panel with adjustable time and temperature. It's the smallest step up from a plain air fryer among the picks.
The drawer is listed as dishwasher safe, which is handy after greasy cooks, and it has a steam clean function to lift oil and food from inside before you wipe it out. SteamFry runs air frying and steam at the same time, so a roast or a whole chicken browns outside without drying out, and steam on its own handles dumplings and vegetables. For a couple or a small family that wants to try steam without paying oven money, it covers the basics, and Sunbeam accessories are easy to find in Australia. If you already own a basic air fryer and want steam, this is the closest swap in size and footprint, so it should fit the same spot on the counter without moving anything else around.
The listing doesn't give a wattage, water tank size or warranty. It's a single drawer, so one dish at a time. Use filtered water, empty the tank after cooking and descale as the manual says, since a small tank scales faster than you'd expect in hard water. Give it its own wall socket, put the drawer through the dishwasher or wash it gently by hand, and keep the vent clear of cupboards and phones on the counter. Wipe the door seal area after greasy cooks, since built-up grease lets steam escape out the front.
Honest caveats: No wattage, water tank size or warranty is stated on the listing. It's a single 7L drawer, and its rank is shared with the Sunbeam Multi Zone. Fewer functions than the bigger Sunbeam, with no bake mode listed. Check the tank's location before choosing where it lives.
Best for: Couples who want to try steam air frying for the least money of the six.
Price: $174 (Amazon AU) • Model: AFP4600BK • Type: Steam air fryer, single drawer • Capacity: 7L • Functions: 6, plus 6 air fry presets • Cleaning: Steam clean, dishwasher safe drawer • Warranty: Not stated on the listing • Rank: #38 in Air Fryers (Amazon AU), listing shared

Dreame AF30 Air Fryer with SmartSteam, 7L, 2300W
ASIN B0GDD221HP • $194 • Ships from Amazon AU
The Dreame AF30 is a 7L air fryer with what Dreame calls SmartSteam 3X Infuse, and Amazon AU sells it for $194. It ranks #56 in Air Fryers, the lowest-ranked of the four air fryers. The listing gives 2,300W, a 50 to 200 degree range, a full colour touchscreen with six signature recipes and six cooking modes, and a nano-ceramic nonstick coating. It also describes a no-flip 360 degree air flow, so food browns without turning. Dreame is better known for robot vacuums than kitchen appliances, so it has less of a kitchen track record than Philips or Sunbeam, and I'd read the reviews closely before buying. The listing doesn't give a model code.
The steam side is described differently from the others. The listing says smart sensors adjust steam levels in real time during high heat cooking, but it doesn't describe a separate steam-only mode, a water tank or where the water goes, so I'd read the manual before buying it as a steamer. Treat it as an air fryer that adds moisture rather than one that steams vegetables on their own. The colour screen is clear and easy to use, and 7L suits a small family. The 2,300W rating is the highest stated of the six. That high rating should mean it heats up quickly, but it also means it's the one I'd be most careful about plugging in anywhere other than its own wall socket in the kitchen.
At 2,300W it sits just under the 2,400W a 10A socket allows, so it needs a wall socket of its own and should never share a powerboard with a kettle. The listing doesn't state a warranty either, so keep the receipt somewhere safe. Clean the nonstick basket gently, since scourers wear the coating, and if it does use a water reservoir, empty it after each cook. Keep the vent clear of overhead cupboards, and check the plug isn't warm after long cooks. If it is, stop using that socket and have it checked.
Honest caveats: The listing doesn't describe a steam-only mode, a water tank, a model code or a warranty. At 2,300W it's close to the limit of a 10A socket, and it's the lowest-ranked of the four air fryers. Dreame has a shorter kitchen appliance track record than Philips or Sunbeam.
Best for: Small families who want a big screen air fryer with a moisture boost rather than a true steamer.
Price: $194 (Amazon AU) • Type: Air fryer with steam infusion • Capacity: 7L • Power: 2,300W stated • Temperature: 50 to 200 degrees • Controls: Colour touchscreen, 12 presets • Warranty: Not stated on the listing • Rank: #56 in Air Fryers (Amazon AU)

What fails on steam ovens and steam air fryers
Small kitchen appliances don't usually come through our workshop, so this part comes from how steam systems are built and from what we see go wrong with anything that mixes water, heat and electronics. Most steam appliances don't die suddenly. The steam gets weaker, the door starts to leak or the panel starts playing up, and the cause is usually water left where it shouldn't be.
Scaled boilers and blocked nozzles
Scale is the number one steam fault. It narrows the tubes and coats the plate or boiler that makes the steam, so less steam comes out and the element runs hotter. Eventually the nozzle blocks and the appliance throws an error or just stops steaming. Descale on the manual's schedule, use filtered water in hard water areas, and if steam slows, run a couple of descale cycles before assuming it's broken. A fully blocked boiler is usually a service job rather than a home fix. Keep the receipt, since an early steam fault may be a warranty claim.
Door seals and condensation
Combi oven door seals harden and split over time, and once they leak, steam runs down the front of the oven onto the controls. Condensation left inside the cavity also rusts paint at the edges. Wipe the seal and the cavity dry after steam cooks, keep fat off the seal and replace it once it cracks. On air fryers, the drawer seal does the same job, and grease built up around it is what lets steam out the front. A soft brush along the seal after greasy cooks keeps it sealing properly for much longer.
Control boards and steam vents
The control board is the expensive part, and moisture is what kills it. Steam leaking past a seal or condensing above a vent can work its way into a touch panel, and that corrosion shows up as phantom presses, dead buttons or random errors. Keep the vent clear, wipe the panel dry, and don't spray cleaner straight onto it. A panel that's started to misbehave after a leak is worth fixing before the corrosion spreads, and on a microwave combi that job belongs to a technician. Unplug before cleaning any panel.
Decision tree: which one should you actually buy?
- Want a true countertop steam oven that bakes and roasts too? → The Cuisinart Gourmet Pro at $448 is a 20L combi oven with steam, air fry and convection, a 1L tank and a 3 year warranty.
- Short on space and want steam in the microwave? → The Panasonic NN-DS59 at $824 is a 27L flat-bed microwave that also steams, grills and bakes, with an Australian plug stated.

Frequently asked questions
What's the difference between a steam oven and a steam air fryer?
A steam oven has a door, a flat tray and enough height for a roasting dish or a loaf tin, so it can bake, roast and steam a tray of food. A steam air fryer is an air fryer with a small water tank that adds steam to the basket, so it crisps food without drying it but only cooks what fits in the drawer. The Cuisinart Gourmet Pro is the oven shape among the picks, and the Philips, Sunbeams and Dreame are air fryers.
Do steam ovens need descaling?
Yes. Boiling water leaves minerals behind as scale, which builds up in the boiler or heating plate and the tubes that carry the steam. In hard water areas that can happen in months. Use filtered water, empty the tank after each use, and run the descale programme on the schedule in the manual, usually with a citric acid or vinegar solution. Don't use a strong bathroom descaler, since it can damage seals and coatings inside the steam system.
Can I use tap water in a steam air fryer?
You can, but in a hard water area it'll scale the steam system faster. If your tap water leaves white marks on the shower screen or the kettle, filtered water from a jug is the easy fix and makes descaling less frequent. Some makers also allow distilled water, while others want a little mineral content for their sensors, so check the manual. Whatever you use, empty the tank after cooking, since water left sitting grows a film that ends up in the steam lines.
How much power does a steam oven use?
The Cuisinart lists 1,875W and the Dreame 2,300W. At the Australian average of roughly 33c per kWh, 1,875W costs about 62c an hour flat out, but the element cycles once it's up to temperature, so a 30 minute cook costs well under half that. The Panasonic's 1,000W is microwave output, not wall draw, and the Philips and Sunbeams don't list a wattage, so read the rating plate. Plug each one into its own wall socket, not a shared powerboard.
Is it safe to put a steam oven under overhead cupboards?
It's safe electrically, but the steam is hard on the cupboards. Steam from the vent condenses on the underside of the cupboard every time you cook, and particleboard swells and peels after a year or two of that. Leave the clearance the manual specifies above the vent, or pull the appliance forward under open space when you cook. Keep the wall behind it in mind too, since steam can lift paint and wallpaper over time.
Can I repair a steam combination microwave myself?
Not the inside. A microwave has a high voltage capacitor that can hold a dangerous charge even when it's unplugged, so opening the case is a job for a qualified appliance technician. What you can do is keep the door edges and seals clean, wipe out condensation after steam cooks and descale the steam system as the manual says. If it sparks, makes new noises or runs with the door open, unplug it and stop using it until it's checked.

Phone been living next to the steam vent?
A phone left charging on the counter beside a steam vent takes on moisture every time it warms and cools, and that slowly corrodes the board inside. If it's started dropping charge, freezing or showing lines, bring it into our Erina workshop. We'll check what's failed and tell you whether it's worth fixing before you spend anything.
