Quick & Efficient Microwaving
Microwave cooking dramatically reduces cooking times and can offer notable energy savings. However it’s often the convenience of microwave cooking which makes it a must have appliance. In microwave cooking, heat is generated directly inside the food so that it can be defrosted, re-heated or cooked in less time compared to traditional cooking. You can defrost by weight or time, reheat, even preparing a full meal is achievable in arguably the handiest appliance in the kitchen, especially combination microwaves with multifunction oven capabilities. Smeg's compact microwave appliances measure 45 cm high and are often combined with complimentary 60cm ovens and 15cm drawers.

Easy Clean Enamel Interior
The enamel finish of the SF4303WMCX oven cavity has a special antacid lining which helps to reduce the amount of dirt adhering to the surface.

Closed Door Grilling
Closed door grilling allows you to grill with the door closed, keeping cooking smells inside the oven and out of the kitchen to ensure a safe cooking environment and reduced energy consumption.

Vapour Cleaning
The eco-friendly Vapour Clean function makes cleaning easy through the use of steam. Simple put a little water mixed with detergent into the hollow of the oven base to generate vapour and release burnt food from the walls of the oven.

Eclipse Black Glass
Eclipse black glass in an innovative, premium material which appears jet back when the oven is off, yet transparent when the oven is turned om, offering enhanced visibility into the oven cavity to check on cooking progress with ease.

My Recipes
The SF4303WMCX is capable of saving 64 favourite recipes along with your chosen cooking function, preferred temperature and duration. It’s quick and simple to setup, especially if you’re struggling for time and regularly cook the same dish.

The history function remembers the last dishes you have cooked. This allows quick selection, and cooking of ‘go to’ meals.

Sabbath Compliant
The SF4303WMCX includes a dedicated Sabbath function which allows you to use the oven during the Sabbath, the day of rest in the Jewish community. It has been specifically designed to meet the strict Shabbat law requirements and as such has been certified Super Kosher compliant by the Rabbis at FedTech (The Federation of Synagogues).

SmegConnect Ovens
Smeg Connect, WiFi enabled ovens allow you to control your appliance by phone or tablet. This is perfect for preheating your oven, setting oven functions and programmes ready for cooking when you return home. The SmegConnect App allows you to add and personalise recipes, try some preloaded Smeg favourites and even share ingredients needed for a dish to ensure you have the groceries you need. To connect please ensure that you have a minimum router capability of 2.4 GHz and IOS 10 or higher for iPhone users or Android 5.3 or Higher.

Telescopic Rails
Selected ovens include a set of telescopic rails as standard, usually an additional purchase. Extending telescopic rails allow you easy access into the oven to safely check hot food, particularly useful when grilling.
