I have a HK AVR7000 there the volume all suddenly raised to a very
high level (luckily not so late at night..). It was no problem to turn
the volume down after it happened and no other problems. It was the
firs time it happen but it will fore sure happen again.. Does somebody
know what could be the fault or experience the same thing?

Causes will vary depending upon type of volume control - motor-driven analog
potentiometer, totally electronic using volume control IC's, you can see
they would be different.

Bad solder connection somewhere or a momentarily stuck front panel or remote
control button are the first things that come to my mind. You probably will
just have to wait to see if it recurs or becomes more frequent before any
real troubleshooting can begin.
