A:AnswerAll of the functions on the Breville® BOV845 Smart Oven® Pro require a time setting which will shut the function off once complete. With no interaction with the oven for a minimum of 10 minutes, the oven will go into a stand-by mode. However, unless unplugged from the wall outlet, the oven will not completely shut off.
