    Overview

    Renowned for creating high quality small home appliances, the Breville Smooth Wave microwave upholds this, using Sensor IQ technology to enable precision when cooking or reheating food. Automatically adjusting its power to find the most appropriate setting, this microwave offers 15 preset programs. Easily navigate your desired program using the simple one touch auto settings, and LCD display.
    Sensor IQ® technology

    Sensor iQ technology is designed to take the guesswork out of cooking by automatically adjusting power to precisely cook or reheat your favourite dishes and delicious treats with ease.

    Power smoothing inverter™

    The Power Smoothing Inverter technology does away with the old ON-OFF method to automatically adjust power intensity and deliver smooth even power when you need more or less, for deliciously even results.

    Soft close door & quieter operation

    The Smooth Wave is engineered with a soft close door which is 80% quieter* and is 50% quieter** in operation. Clever touches like child lock, Breville sound suite and mute button means fewer beeps, bumps and clangs, and more pops, bites and crunches.

    Shortcuts & one touch auto settings

    Cleverly designed shortcuts panel on the inside door of the Smooth Wave, for commonly used tasks such as melting chocolate, softening butter, reheating pizza and more. Set your favourites with one touch and get delicious results every time.
