This is the Just Answer website and not Technika, just so you know, please supply me the model number of the oven and I will assist you in finding the user manual okay, Cheers,
Hi Aussie repair tech.....I don't have a model number, there is nothing visible on the stove to indicate a model or serial number, but the house is only seven years old, so the stove/oven is not very old....the oven is just simply called "Bellissimo Technika". It's a very homely large, all stainless steel, looking piece on legs, which purch it of the floor by approximately 160cm. EAsy for cleaning under the beast..
There are a lot of different Bellissimo ovens, and dishwashers, so finding the exact manual will be kind of hard without a model number. If you look at this page, it will describe the different Icons on their ovens, and may assist you in finding the info you require.
Are you sure there is no sticker attached to the side of the door?

Maybe take a picture, and email them direct with your request, tell them you desperately require one and the model number has worn away,, so you cannot identify the model etc..
