Impressa x7-s rinsing programme

Hello to all Jura x7 and x7-s friends
I rebuilt my Impressa x7-s today after a complete overhaul, and of course tested it with great joy.
Had to find out that the flushing program doesn't work properly somehow.

I turn on the usual, and then press the flush button.
You rinse the milk nozzle but don't stop then I press the
Rinse button for the second time, rinse the milk nozzle stops and then the coffee spout rinses as it should be.

Used your help there.
Before everything ran the way it should.
Could it be, it stood now some weeks in my workshop that the solenoid valves have tightened themselves?
Could not be but, however, or???it works perfectly!
Up to the rinsing program.

And you can't stop the
rinse normal either...???

Or you could do that before too??
