    Overview

    If you’re after the cooking prowess of a convection oven and the ease of use of a microwave, you can get the best of both worlds with this 44L built-in combination microwave and oven from Westinghouse.

    When you hear the word “microwave”, you think of leftovers, hot chocolate, and popcorn. This Westinghouse combi microwave-oven offers so much more, but with the ability to prepare those old favourites too. You have the choice of 10 cooking functions, including roast, bake, and grill. Go a step further and upgrade your static grill to grill plus microwave or grill plus convection. These combination cooking modes help you to prepare meals faster and with more even results. For tailored cooking performance, consult the 13 Auto Cook menus. These menus, including Pizza, Cake, and Fresh Vegetables, already have the power, cooking time, and temperature set. All you have to do is enter the weight of your food. Navigate the oven’s features using the handy touch controls. They are as easy to clean as they are to use, and they come with a child safety lock to keep little ones from becoming master chefs before their time.

    From quick reheats to three-course meals, it’s all possible with this Westinghouse combi microwave-oven.
    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.

    Great Quality
    [This review was collected as part of a promotion.] We wanted to replace our previous Westinghouse microwave combined wall oven and have been very pleasantly surprised with the quality of our new purchase.

    Stylish, Spacious, and Surprisingly Versatile – A Perfect Fit for Our New Kitchen
    [This review was collected as part of a promotion.] As part of our full kitchen renovation, we chose the Westinghouse 44L built-in combi microwave in dark stainless steel, and it has turned out to be one of our favourite upgrades. The sleek dark finish blends seamlessly with the rest of our cabinetry and appliances, giving the entire kitchen a clean, modern look that feels both premium and timeless. What sets this unit apart is its versatile functionality. It’s not just a microwave – it combines microwave, convection, and grill functions, which has made everything from reheating leftovers to baking and grilling incredibly convenient. Whether it's a quick defrost or cooking a full meal, this appliance handles it effortlessly. The touch control panel is very intuitive, with auto cook and auto defrost settings that take the guesswork out of everyday use. Even with all its functions, it still feels simple and user-friendly. With a 44-litre capacity, it’s much more spacious than we realised, we can comfortably fit larger dishes, which is especially handy when cooking for the family or hosting guests. Overall, the Westinghouse 44L built-in combi microwave delivers an excellent blend of style, convenience, and performance. If you’re renovating your kitchen or looking for a premium built-in option, this one is absolutely the right choice!!. Westinghouse has truly delivered a reliable, modern appliance that elevates our kitchen and makes everyday cooking easier.

    Amazing microwave
    [This review was collected as part of a promotion.] Was bit sceptical to buy an expensive product because am mainly going to use this as microwave, but so far it has really impressed in looks and functionality. Haven't used oven yet and had to clean only once.

    Hi there, is this unit suitable for under bench installs? If so, are there modified instructions. I want to install this unit under the kitchen bench not in a tower. Craig · 2025-03-07
    Hello Thank you for this product question. Yes, any single oven can be installed under the benchtop or placed in a wall installation. This model requires a 14-amp electrical connection and needs to be on a separate electrical connection from the powerboard to the oven location. On our website, we have included the user manual that you can download, which has installation details for your cabinet maker and electrician; please download this manual with installation information, pages 15 onwards. I hope this information will assist you when shopping with us at Appliances Online. Our Sydney-based team is available 24/7 to assist you at Ph: 1300-000-500. Colin Jones, Appliances Online
    Is there a SS trim kit available for this oven? Tony · 2024-01-14
    Hello Tony, Thank you for your product question. There is no trim kit available for this model because it is not necessary when integrating this unit into a cupboard. The dimensions of 595mm are comparable to the typical width of most 60cm ovens, making it suitable for installation either above or below an oven. This model can be installed as a standalone unit. For detailed installation instructions, please refer to the user manual, starting from page 15. I trust that this information will prove helpful as you shop with us at Appliances Online. Our Sydney office operates around the clock 24/7, and you can reach us at 1300-000-500. Colin Jones, Appliances Online
