The Siemens IQ-300 SN73HX10VG is a fully integrated, full size dishwasher designed to disappear behind your kitchen door while quietly getting through the family washing up. With 14 place settings, flexible baskets and a decent choice of programmes, it’s clearly aimed at busy households that want hassle-free cleaning.
Siemens sits at the more premium end of the built-in appliance market, and this model reflects that with Wi‑Fi connectivity, app control and thoughtful touches like rackMatic height adjustment and a cutlery drawer. At this price it’s a mid-to-upper range machine rather than a bargain buy.
Owners rate it highly, with an average score of 4.7 out of 5 from user reviews, which backs up the impression that you’re getting dependable cleaning performance and solid build quality.
This Siemens IQ-300 is best suited to medium-sized households that run the dishwasher most days. With space for 14 place settings, it will comfortably handle the dishes from a typical family of four, including larger dinner plates, pans and glassware.
It’s a good choice if you’re planning or updating a fitted kitchen. The fully integrated design requires your own matching furniture door, and the sliding door fixing (varioHinge) makes it easier to line up with modern handleless or low-plinth units.
If you appreciate convenience and smart features, this model stands out. Wi‑Fi and Home Connect let you start or monitor cycles from your phone, and the machine can even flag up when you’re running low on tablets. Auto programmes, an intensive option and quick washes mean you don’t have to fiddle with settings for every load.
Budget-conscious buyers looking for the absolute cheapest full-size dishwasher may find this a stretch, and those with very small kitchens or households of one or two might prefer a slimline model. But if you want a feature-rich, built-in dishwasher that will cope with daily family use, it’s a strong fit.
The 14-place-setting capacity makes it ideal for families or anyone who regularly entertains, as you can fit a full day’s dishes in one go.
Flex Baskets, the varioDrawer cutlery tray and rackMatic height-adjustable upper rack give you plenty of loading flexibility. Taller pans or stemware are easier to accommodate than on many basic machines.
varioSpeed Plus is genuinely useful when you’re in a hurry, cutting the length of many cycles without sacrificing cleaning results – handy after a dinner party or when you need plates turned around quickly.
Wi‑Fi and Home Connect add smart convenience. You can check remaining time, get maintenance alerts and be reminded when salt or rinse aid are running low, which helps you avoid streaky glasses and poor results.
Water consumption of around 9 litres per cycle is efficient for a full-size machine, helping keep running costs and environmental impact down.
Useful quality-of-life touches such as the audible end-of-programme signal, remaining time indicator and floor infoLight mean you always know what the machine is doing, even though it’s hidden behind a cabinet door.
The D energy rating isn’t class-leading by today’s stricter standards. It’s not wasteful, but there are more efficient (and typically pricier) models if ultra-low running costs are your top priority.
The interior is mainly plastic rather than full stainless steel, which is common at this level but slightly less premium in feel and potentially a touch less robust long term.
There’s no specific half-load or zone-wash option listed, so if you often run very small loads you won’t be able to optimise water and energy use quite as much as on some competitors.
Noise at 46 dB is reasonable but not ultra-quiet. It should be fine in most homes, but in open-plan living spaces particularly sensitive users might notice it during quieter moments.
A two-year manufacturer warranty is decent, yet some premium brands now offer longer cover on certain models, which could be reassuring for an integrated appliance that’s harder to replace.
Day to day, the Siemens IQ-300 SN73HX10VG is designed to be straightforward and unfussy. Electronic controls with push buttons and touch keys keep the front panel clean and simple to read, while the built-in time-remaining indicator means you’re not left guessing when the cycle will finish.
Loading is intuitive. The adjustable top basket and Flex Baskets give you different folding tines and sections to accommodate everything from cereal bowls to casserole dishes. The varioDrawer at the top replaces a traditional cutlery basket, freeing up space in the lower rack and making knives and utensils easier to separate for better cleaning.
The 46 dB noise level means you’ll hear a gentle whoosh in a quiet kitchen, but it’s more of a background hum than a disturbance. Silence on Demand lets you temporarily reduce noise during particularly quiet times, which is handy if the kitchen is near bedrooms or a home office.
Maintenance is kept relatively simple. Integral water softening helps protect against limescale in hard water areas, and clear salt and rinse-aid indicators prompt you when top-ups are needed. The triple water protection system and AquaStop-style safety reassure you that leaks are very unlikely. With app alerts for maintenance and low consumables, you’re nudged to keep everything running smoothly without needing to remember.
Core washing performance is supported by a sensible mix of six programmes, covering Auto (45–65°C), Economy, Intensive, two quick options and a custom programme. Auto mode will be the go-to for most users, automatically adjusting water, temperature and duration to match how dirty the load is, saving you from choosing settings manually.
For heavily soiled pans or baked-on dishes, the intensive zone and high maximum temperature of 70°C give the machine the power to shift stubborn grime. At the other end of the scale, Quick L and a 45°C quick wash provide faster turnarounds for lightly soiled items, particularly when combined with varioSpeed Plus.
Drying is handled by a heat exchanger system, which is typically more efficient and gentler on delicate glassware than simpler plate-warming elements. Glasses and plastics should come out drier and with fewer watermarks when used with rinse aid.
Smart functionality is a major part of this model’s appeal. With Wi‑Fi and Home Connect, you can start or schedule cycles, choose programmes, check on progress and receive notifications straight to your phone. The app can also highlight any issues with water intake or maintenance, so you can address small problems before they become bigger ones.
Installation-friendly touches like adjustable feet (accessible from the front), a sliding door fixing kit and varioHinge make it easier for fitters to align the appliance perfectly in a modern kitchen. The internal infoLight projected onto the floor lets you know when the machine is running – particularly handy with integrated models that hide their controls once the door is shut.
At around £599, the Siemens IQ-300 SN73HX10VG sits in the mid-to-upper price bracket for full-size integrated dishwashers. It’s not a budget pick, but you are paying for a richer feature set than many entry-level models.
The combination of 14 place settings, flexible storage, Auto and intensive programmes, decent efficiency and a sophisticated drying system would already be competitive at this price. Adding Wi‑Fi, Home Connect, varioSpeed Plus, Silence on Demand, varioDrawer and rackMatic height adjustment strengthens the case further.
The D energy rating stops it from being a standout on running costs, and the two-year warranty is solid rather than exceptional. However, the strong 4.7/5 user rating indicates that buyers generally feel they’ve received good value in terms of performance and reliability.
If you’re simply hunting for the cheapest integrated dishwasher, there are plainer alternatives. But if you want a smart, well-specced model from a respected brand, the overall package justifies the asking price for many households.
The Siemens IQ-300 SN73HX10VG is a well-balanced, feature-rich integrated dishwasher that should slot neatly into most family kitchens. It offers generous capacity, genuinely useful loading flexibility and a strong spread of wash programmes, all wrapped in a discreet, built-in design.
Smart features such as Wi‑Fi, Home Connect, varioSpeed Plus and Silence on Demand add real everyday benefits rather than being gimmicks, while the integral water softener and protective systems are reassuring if you live in a hard water area or worry about leaks.
It’s not the quietest or most energy-efficient model available and the warranty is fairly standard, so efficiency purists or those on tighter budgets might want to compare a few options. For everyone else looking for a dependable, modern, fully integrated dishwasher with a touch of smart convenience, this Siemens IQ-300 is an excellent all-round choice.
