What you need is " Regeneriersalz ", you'll find it with the dishwasher products. There is a big flap inside the bottom of your machine, you open it and pour in the whole box of salt, that's it.
Miele machines take 1-2kgs of salt. Any kind of salt is fine, just that the one with added iodine is intended as cooking salt. Roll out the bottom tray in the dishwasher and look for a white cap with an "S" on it. Turn it to open and pour in as much salt as will fit. Water will spill out, that's okay. Keep pouring until it can't fit any more salt.
The person who installed my Miele said that table salt is fine, just more expensive. I was really keen on trying out my new machine and table salt was all I had in the cupboard. Best machine i've ever used with a delicates cycle for glasses and a quick wash. Even the tray heights adjust to fit larger items.
BTW: It was ready to go right away and no need to run it once without dishes.
My Miele Instructions say that when you have filled it, you should run it. I always re-fill the salt compartment in mine when the machine is full, ready to be used. Then I switch it on straight away. If you don't have a load, run the cold programme.
The instructions also say 'use only special dish-washer salt'.
Or you can look on www.miele.co.uk and see if you can find yourself. The model number may not be identical, just look for a panel that looks like yours.
Recently I found that the V Zug website offers the option to download manuals in English.
Good idea to get the manuals in English. It took me around 6 months to figure out that my oven was also a microwave. I was also storing my cookbooks in the plate warming tray
DO NOT over fill the salt compartment as the salt becomes compacted and will not run through. I have Miele appliances and I had a problem with the dishwasher because of the compacted salt.
Baby, you also may need to top up the rinse-aid fluid so you don't get streaks. Usually the lil' cap is on the inside of the door, with a lil' hole to pour in the fluid. It looks something like this, but get the Eco version :
