The AEG OB6SM171DB is a 17-litre built-in microwave designed for smaller households and streamlined modern kitchens. With its glossy black glass front, it’s made to sit neatly alongside matching AEG appliances rather than dominate your worktop.
This is a straightforward 800W standard microwave, focused on everyday reheating, defrosting and simple cooking rather than fancy combination or grilling functions. Electronic controls and 8 automatic programmes are there to take the guesswork out of timings.
Priced firmly in the mid-to-premium bracket for a compact microwave and backed by a strong 4.8 out of 5 rating from owners, it looks like a reliable choice if you want a built-in model that prioritises simplicity, style and solid day-to-day performance.
The AEG OB6SM171DB is best suited to smaller households, couples or singles who mainly need a microwave for reheating leftovers, defrosting and the odd quick meal. Its 17-litre capacity and relatively low internal height (190 mm) mean it’s not ideal if you regularly use large dishes or tall containers.
If you’re planning a fitted kitchen and want a clean, seamless look, this built-in model makes far more sense than a freestanding microwave on the worktop. The glossy black design is specifically intended to match other black AEG appliances, so it will particularly appeal if you’re already committed to that look.
It’s a good fit for buyers who value ease of use over advanced cooking functions. The electronic controls, 5 power levels and 8 automatic programmes are straightforward to get to grips with, even if you’re not especially tech-savvy.
However, if you want a microwave that can also brown, crisp or handle full roasting duties, this isn’t the right choice. There’s no grill or convection mode, so keen cooks who want an all-in-one combi oven will be better served by a more fully featured model.
The compact 17-litre capacity and 37.1 cm height make this a great option for small kitchens or where cabinet space is tight, without sacrificing a standard 59.4 cm built-in width for a fitted, integrated look.
An 800W maximum microwave power is ample for everyday cooking and reheating, helping meals and drinks heat through quickly without feeling underpowered.
Eight automatic programmes with weight control mean you can simply select the food type and let the microwave work out timings, which reduces the chances of overcooking or cold spots.
Electronic controls and a clear glass front give it a modern, fuss-free feel. It’s easier to set precise times and power levels than with older rotary dials, and the interior light makes it simple to keep an eye on your food.
The included steam cooking set is a nice bonus, letting you steam vegetables or fish more gently than in a pan, which is rare on a compact built-in at this size.
A 2-year manufacturer warranty offers more peace of mind than the basic 1-year cover found on many cheaper microwaves.
At 17 litres, the cavity is on the small side, and the 190 mm internal height limits the size of taller dishes or lidded containers you can use comfortably.
There’s no grill or conventional cooking function, so you can’t brown or crisp foods in the way a combination microwave would – it’s strictly for microwaving.
With only 5 power levels and 8 programmes, the feature set is fairly basic compared with some similarly priced models that offer more specialist settings.
The turntable diameter is quoted as 272 cm, which clearly should be 27.2 cm – in reality that means standard dinner plates will fit, but oversized plates or large square dishes may be a squeeze.
Power is listed oddly as “0 Watt” in places in the spec sheet, which is clearly an error; while the 800W microwave power is fine, the documentation could be clearer.
Day to day, the AEG OB6SM171DB is designed to be as straightforward as possible. The electronic control panel lets you tap through power levels, set cooking times precisely and choose from the 8 auto programmes without much of a learning curve.
The interior is painted rather than stainless steel, which helps keep the price sensible and is generally easy to wipe down after splashes or spills. The built-in interior light makes it simple to see when food is boiling over or nearly done, so you can stop the cycle early if needed.
With a 27.2 cm turntable, most standard plates and bowls will rotate freely, reducing cold spots. However, very wide dishes or square storage containers might need to be repositioned or decanted. The compact inner dimensions are noticeable when reheating larger portions.
Installation is straightforward for a professional: it’s a standard 59.4 cm-wide built-in appliance with a 1250W electrical connection and a 10-amp fuse rating, so it should integrate easily into a typical UK kitchen cabinet and socket arrangement.
The 140 cm power cable is generous enough to give some flexibility on where the socket sits behind or near the housing, which makes life a bit easier for installers and fitters.
Performance-wise, the 800W maximum microwave power strikes a good balance between speed and control. It’s strong enough to heat soup, ready meals and leftovers quickly, but not so fierce that everything ends up bubbling over in seconds. Five power levels give you enough granularity to gently defrost or reheat delicate items like fish or sauces.
The 17-litre capacity and 285 x 290 mm internal footprint mark this out as a true compact built-in model. For single portions, mugs, baby bottles and smaller dishes it’s ideal, and the small cavity generally means more even heating as there’s less space for microwaves to dissipate. For family-sized casseroles or large baking dishes, though, this isn’t the most practical choice.
One of the standout features at this size is the inclusion of 8 automatic programmes with weight control. Being able to input the weight and let the microwave decide on cooking time is particularly handy for defrosting meat or cooking vegetables without constant trial and error. It’s especially helpful for less confident cooks or busy households who just want to press a couple of buttons and walk away.
The sleek black glass front is more than just cosmetic. Because this is designed to match other AEG appliances, it helps create a coordinated run of ovens and microwaves, which is something you usually see in more premium kitchens. The glass front is also easy to wipe clean and doesn’t show fingerprints as badly as some stainless steel fronts.
While the feature set is deliberately focused and there’s no grill or convection mode, the inclusion of a steam cooking set adds a bit of versatility. It allows for healthier cooking of vegetables and fish, retaining moisture and nutrients better than blasting them in boiling water. Coupled with the interior light and simple controls, it makes this a solid, practical performer for everyday microwave tasks rather than an all-singing, all-dancing cooking centre.
At around £319, the AEG OB6SM171DB sits at the higher end of the scale for a compact microwave, though some of that cost reflects its built-in design and premium brand positioning rather than raw features alone.
You’re paying for a neat, integrated look, strong build quality and the reassurance of a 2-year manufacturer warranty, rather than for a long list of advanced cooking modes. If you simply need a freestanding microwave, it will be easy to find cheaper alternatives with similar power.
However, for an integrated model, the specification is sensible and the user experience is clearly resonating with owners. A 4.8 out of 5 average rating from 24 reviews suggests high satisfaction with performance and reliability, which strengthens the value argument.
Overall, it represents fair value for homeowners planning a fitted kitchen who want a dependable, stylish built-in microwave with just enough extra convenience (like auto programmes and the steam set) to justify the price, but it’s less compelling if you’re purely shopping on features-per-pound.
The AEG OB6SM171DB is a well-executed compact built-in microwave that does the basics very well. It offers reliable 800W performance, simple electronic controls and genuinely useful automatic programmes, all wrapped in a sleek black glass design that will sit neatly alongside other AEG appliances.
Its strengths lie in day-to-day convenience for smaller households and in helping deliver a clean, coordinated fitted kitchen. Owners clearly rate it highly, and the 2-year warranty adds extra reassurance.
On the flip side, the 17-litre capacity and modest internal height limit its usefulness for large dishes, and the lack of grill or convection functions means it won’t replace a traditional oven or combi microwave. If you’re after a compact, integrated workhorse for reheating, defrosting and simple cooking, it’s an excellent choice. If you want one appliance to do everything, you’ll need to look higher up the range.
