    Overview

    The Westinghouse WMB4425DSC 44L Built-In Combi Microwave brings microwave convenience together with convection and grill cooking, giving busy households a versatile appliance for reheating, defrosting, baking, roasting and grilling. Finished in dark stainless steel, its fully integrated design coordinates neatly with other Westinghouse built-in cooking appliances for a streamlined kitchen.

    With a generous 44 litre capacity and 900W microwave output, this built-in combination microwave provides plenty of flexibility for everyday meals. Beyond standard microwave cooking, convection and radiant grill functions expand what you can prepare, while three combination cooking modes let you combine technologies for efficient cooking with browned and crisped results.

    For easier meal preparation, 13 Auto Cook options take much of the guesswork out of selecting settings. Simply choose the appropriate program and enter the food weight, and the appliance determines the required cooking parameters. Auto Defrost provides additional convenience when preparing frozen ingredients.

    The full touch electronic controls provide straightforward access to temperatures, cooking times and functions, complemented by an LED display and programmable timer. Ten microwave power levels give you greater control when moving between gentle heating and more powerful cooking tasks, while the child safety lock helps prevent unintended operation.

    Measuring 595mm wide, the Westinghouse WMB4425DSC 44L Built-In Combi Microwave is a practical choice for kitchens where the versatility of microwave, convection and grill cooking is wanted within one integrated appliance.
    13 Auto Cook programs

    As life gets busier, it helps to have some convenient shortcuts up your sleeve in the kitchen. With 13 Auto Cook programs to choose from, you can place your food inside the cavity, set the weight, and trust the microwave to select the appropriate power, cooking time, and temperature.

    Combination cooking

    Take your microwaving to the next level with the help of three combination modes. Choose between Microwave + Grill Cooking, Microwave + Convection Cooking, and Microwave + Grill Fan Cooking. The initial microwave heat will result in faster cooking times compared to a conventional oven.

    Seamless integration

    This microwave has been designed to seamlessly blend in with other appliances in the Westinghouse built-in family, helping you turn your house into a home.

    Child safety lock

    This appliance is safe for family households thanks to its child safety lock. When you activate this setting on the touch control panel, curious hands won’t be able to operate the unit by accident.

    Life Changing microwave
    [This review was collected as part of a promotion.] I so Happy With this new microwave the twin use is just so amazing easy to use.Wish i had it years ago

    Absolute trash
    More useless as a microwave than anything I've ever seen. If you like part of your food literally charcoal and on fire, while another part is still cold and icy - this is the microwave for you. Completely useless, every use as a microwave does not work at all, and is a hazard. This should be removed from sale. Clearly the technology is not ready yet.

    Needs some tweaking for the price
    [This review was collected as part of a promotion.] Was a bit sceptical as to whether we would use all the features in this microwave as we are in our mid to late seventies and previously have only used a very basic microwave. The features on the panel are very hard to see and would benefit from lighting behind panel. At this point in time we require a torch to read them as the background is black. Our previous microwave does seem to have more power than this one but hopefully over time, we will be able to navigate the other features
