Flexible combination cooking
This appliance is designed to cover several cooking tasks in one built-in unit. Microwave power can be used on its own or combined with fan oven heat, grilling or roasting functions to support quicker cooking while aiming for an even finish.
The 43-litre cavity, three shelf levels and temperature range up to 250°C give it useful flexibility for everyday baking, roasting, reheating and defrosting. QuickMicrowave provides rapid access to maximum microwave power, while Quick & Gentle allows the microwave contribution to be adjusted alongside conventional heat.
Precision and convenience
The wired food probe is a notable feature for cooking meat and fish, as it monitors core temperature while the food cooks. Automatic programmes, recommended settings, programmable start and end times, and a time-left display can reduce the amount of manual adjustment required.
The M Touch display, MotionReact lighting and display response, SoftOpen and SoftClose features give the appliance a more considered user experience. Miele@home connectivity and related functions add remote and supervisory options, although their usefulness will depend on how much connected control you want from a cooking appliance.
Cleaning, installation and daily ownership
The stainless-steel oven compartment has a PerfectClean finish intended to reduce residue build-up, while the CleanGlass door and CleanSteel front are designed to simplify routine cleaning. Cooling and touch-cool features, safety switch-off, system lock and sensor lock provide additional reassurance during use.
At 595mm wide and 456mm high, this is a compact built-in appliance, but installation still requires careful checking of the stated niche dimensions, electrical requirements and available ventilation. The supplied rack and two glass trays help it arrive ready for a range of cooking tasks.
