New and used dishwasher ⇐ Bosch

[TernyFolls]

Hello everyone
When we moved to a new apartment, the former residents left behind a kitchen, including a built-in Bosh machine. It’s been standing for a long time, it’s been used before, it’s connected, it even lights up when you turn it on. I myself had never even thought about buying it before, but here I’m using it) I myself am more into computers and other electronics, my maximum is to connect the washing machine according to the instructions.
Please help me with the following questions
what should I do first? In such a situation, according to the former owner, the machine was not used for plus or minus half a year, is it possible to start using it right away, or are some preventive measures needed, prepare the device, etc?
how to use the machines in general? Maybe you can provide some links, I couldn’t figure it out myself, there is too much new information, I would like a manual with the basics and without any special difficulties)
On the door, in addition to the Finish\Calgonit sticker, there is an engraving, how to read it correctly?

as well as voltage, power and other characteristics

Please forgive me if my questions are trivial, and thanks in advance

TernyFolls, hello! I think the machine can be used right away. What could happen to her in six months? First start it in short mode, stand nearby, make sure nothing flows from anywhere. You never know what’s wrong with the fill/drain hoses. So as not to flood the neighbors.

Then, as you use it, you’ll see if the dishes don’t shine, then you’ll need to add salt from the special compartment and add rinse aid.
