Zanussi Geschirrspüler Salzmenge, Wasserhärte, Klarspülmenge, Maschine Care, Tür Funktion einstellen

How to adjust the salt level, water hardness, rinse aid level, Machine Care, and door function on the Zanussi ZDLN-5521 dishwasher. Since these functions are somewhat hidden or "complicated" to use, I've uploaded a video because I couldn't find one on YouTube. It's also good for me to look at if I forget how to do it in a few years ;-).
