Hello,
 
that sound is from the electric-magnet at the drainage-valve.
 
When the brewing stops, the fluidsystem would rinse through the nozzle

So this problem is solved by the drainage-valve, which lets the water out and air in
 
to stop the tripping.
 
The electric magnet knocks a steel-needle at a plastic cap which is mounted to
 
a metal axle in the valve which then opens.
 
Sometimes these Juras make awfuawful humming noises while the electric-magnet
Sometimes these Juras make awfuawful humming noises while the electric-magnet

As long as the knock sound and the humming is only hearable while the drainage-valve has

Friendly greets and good luck. :)
