Would recommend to a friend




This microwave is a good size for a busy household – it’ll make the perfect companion to the main kitchen oven. It allows you extra flexibility at mealtimes to cook or heat food quickly and easily. The turntable will comfortably hold a standard sized dinner plate, so you’ll also be able to reheat your dinner in no time on those nights when you’re late home from work.


Defrost function

Quickly and hygienically defrost food thanks to the specialised function included on this model. You’ll never have to leave frozen meat to thaw in your kitchen all day again – simply place in the microwave and select the defrost setting. Your food will be thoroughly defrosted so it’s safe and ready to be cooked in no time.

Isofront Plus door

Keep the heat inside the oven with the Isofront® plus quadruple glazed door on this AEG microwave oven. Constructed from layers of specially coated glass designed to resist heat, the door insulates the oven – helping to maintain the temperature inside. And, because the heat’s trapped in, the door stays cooler to the touch, so little fingers won’t get burned.

ProSight display

This microwave oven from AEG innovatively combines user-friendly touch controls and a large LCD Prosight display screen to ensure that it’s always easy for you to keep an eye on your cooking settings. The clear LCD screen displays the time, cooking mode and temperature – all of which can be accurately adjusted using the sleek touch control panel – so you can carefully monitor the whole cooking process to ensure your food is always cooked to perfection.

Microwave and grill

With a handy grill feature, this microwave is a real multi-tasker. As well as functioning like a standard microwave, this model also has a grill setting so you can crisp up some bacon or make some cheese on toast without having to turn on the oven. You can even choose to use a combination of the microwave and grill functions to cook food through and then get a delicious golden brown finish on top.

    Product Tester

    Very Clever Technology in this Microwave Oven

    Pros:Ease to use, Good build quality, Looks good, Pizza Function, Quiet, Value for money

    "I was amazed by how much this Oven can actually do, not only you have all the features of a microwave with loads of presets for cooking all kinds of food and lets not forget without the annoying spinning plate inside, but also the full use of a Fan assisted Oven, grill and even a facility to cook Pizza to perfection ! My pizza came out super crispy on the bottom and with perfectly cooked toppings. Also loved the Dough proving facility and Bread baking sets.... SOOOOO easy to bake with it. Can be a touch complicated to use in the first few days because it has so many features but in all honesty after 4-5 days I'm like a pro already ! "
