3-in-1 Oven and Microwave Cooking

Microwave power is electronically controlled across 80, 150, 300, 450, 600, 850 and 1000W settings, while oven temperatures can be selected from 30°C to 250°C.

Special applications and automatic programmes provide additional flexibility for different cooking requirements.

Quick & Gentle Microwave Technology

Quick & Gentle uses inverter technology to combine conventional heat with an infinitely adjustable supply of microwave energy. This allows the microwave power to be tailored precisely to your cooking requirements, helping reduce cooking times while providing greater flexibility.

For fast reheating, Quick Microwave starts the highest microwave setting at the press of a button. Defined time values can also be reprogrammed to suit your preferences. A dedicated Popcorn function uses preset timings and wattages for a 100 g packet of microwave popcorn, with the cooking time adjustable to your preferred result.

M Touch Controls with MotionReact

The large M Touch display provides intuitive control of the appliance, while the MotionReact proximity sensor responds as you approach. MultiLingua offers a wide selection of display languages, and functions including MyMiele, user programmes, individual settings, a help function and recommended temperature and microwave power settings make day-to-day operation straightforward.

The handleless ArtLine design incorporates Touch2Open for convenient opening, while SoftOpen provides controlled, cushioned door movement. The door opens to 90° for easy access to the oven compartment.

Automatic Programmes and Wired Food Probe

Automatic programmes electronically control the settings required for a wide range of dishes, reducing the need to select the function, temperature and cooking duration manually. The degree of cooking can also be adjusted for suitable dishes, with microwave assistance available to shorten cooking times where applicable.

A supplied wired food probe measures the core temperature of fish and meat for more precise cooking. The time-left display indicates how much longer the food requires, helping you monitor cooking without repeatedly checking the oven.

43-Litre PerfectClean Oven Compartment

The 43-litre stainless-steel oven compartment provides three shelf levels and features Miele’s patented linen structure with a PerfectClean finish. The specially structured surface is scratch-resistant and designed to reduce the amount of residue that adheres during cooking, making the compartment easier to clean.

A hinged grill element and CleanGlass door further support easier cleaning, while a maintenance-free, energy-efficient LED spotlight provides clear illumination inside the oven.

Crisp Function and Flexible Cooking Modes

The Crisp function reduces moisture inside the oven compartment to help foods such as chips and potato croquettes develop a crisp exterior. Rapid heat-up, pre-heating and a keeping-warm function provide further flexibility for different cooking tasks.

Fan Plus supports gentle baking and roasting on up to two levels, while Intensive Bake is suited to dishes requiring crisp bases and moist toppings. Low Temperature Cooking provides even cooking at lower temperatures, and Auto Roast sears meat at a high temperature before continuing at the selected roasting temperature.

Miele@home Smart Connectivity

The network-enabled Miele@home system allows compatible Miele domestic appliances to be connected through a home WiFi router and the Miele Cloud. Depending on the available digital services, functions can include operation through the Miele app, push notifications, RemoteUpdate, voice control and integration with compatible Smart Home solutions.

Miele@home is a separate digital offer from Miele & Cie. KG. Functions can vary by model and country, and use requires acceptance of the relevant terms, conditions and privacy policy in the Miele app. Miele reserves the right to change or discontinue the digital offer.

Programmable Timer Functions

Timer functions allow you to programme the start time, end time or duration of a cooking process, with the appliance automatically ending cooking when the programmed duration has finished. An integrated minute minder is also included, while the set time is retained for approximately 150 hours in the event of a power cut.

Safety and Efficient Operation

The appliance cooling system helps keep the controls and adjacent cabinetry relatively cool, while the multi-layer door construction helps maintain a low temperature on the outside of the door. Safety functions include a system lock, sensor lock and automatic safety switch-off if the maximum operating time is exceeded.

Automatic residual heat utilisation allows the appliance to switch off early and use remaining heat to complete the cooking process. Power consumption is 0.3W in off mode, 0.8W in standby mode and 2W in networked standby, with automatic switching after 20 minutes.
