Miele in the Netherlands was very helpful with finding out the age of my small Miele toploader. I would advise to call Miele Norway and see if they can help you to find out the exact date of the production of this dryer.
That's completely wrong indeed. Theo is right with ca. 1985. I got the boxes with Miele brochures from the shelves. This range was introduced in 1982 and I have a brochure of a newer range from 1987. That is as close as I can estimate the age of this dryer.
I also think so, because I've fixed up the G560 to my grandma, and that machine has the same touchpanel and so, and it dates from 1984. It's right if we say mid 80's
