Cooking versatility
This appliance is designed to cover a wide range of cooking tasks, including baking, roasting, grilling, reheating and defrosting. Microwave combination modes can pair microwave energy with fan-oven cooking to help reduce cooking time while supporting even results.
Quick & Gentle cooking combines conventional heat with adjustable microwave energy, while automatic programmes can select cooking settings for supported dishes. The stated 30°C to 250°C temperature range also accommodates low-temperature cooking as well as more conventional oven use.
Precision and convenience
The integrated wired food probe is a notable feature for anyone who regularly cooks meat or fish. It measures core temperature and can work with the appliance’s target-temperature settings, helping reduce guesswork when aiming for a preferred degree of cooking.
The M Touch display, Rapid Heat Up, Keep Warm, Crisp function, programmable timings and MotionReact features are intended to make everyday operation more convenient. A time-left display and temperature indicators provide additional cooking information.
Design, cleaning and installation
The 43-litre cavity gives this compact built-in appliance practical cooking space, with three shelf levels and an LED oven light. The stainless-steel interior has a PerfectClean finish, while the CleanSteel front and CleanGlass door are designed to make routine cleaning easier.
Before installation, the available product information indicates that the kitchen niche should measure between 560mm and 568mm wide, 450mm and 452mm high, and 550mm deep. The appliance weighs 38kg, so suitable support and careful installation planning are important.
Connected features and safety
Miele@home, WiFiConn@ct, MobileControl, RemoteService and SuperVision display provide a broad set of connected-home functions. These features may appeal to households that want appliance monitoring and control within a wider smart-home setup.
Safety provisions include an appliance cooling system, touch-cool front, safety switch-off, system lock and sensor lock. The supplied information also lists residual heat utilisation and low power figures for off, standby and networked-standby modes.
