Noise Jura Impressa F70

Hi, I have a problem with my Jura Impressa F70 automatic coffee machine.
About a week ago, the display said that I should descale the coffee machine.
Then I started the descaling process. After just a few seconds, the machine rattled. Error 8 lit up in the display and the descaling process stopped.
After a few more failed attempts, I ordered a revised brew group for this model at BND-Kaffestudio.deAfter
yesterday's installation of the new comes again coffee from the fully automatic
.
But at the end of the brewing noise, a disturbing noise sounds from the machine. Since the noise also sounds at the start of the machine, when you press "care" and water runs out. I suspect that the noise is related to the water outlet. But I can also be wrong. Attached is a video of the coffee spout.
Can someone help me or can give me a reason for this problem?
Greetings
Felix

Hello,

this is the solenoid from the drain valve. There is a brass sleeve in it. If you're lucky, it's only come loose. The solenoid sits between the pump and flowmeter.

Ah okay thanks. Then I'll make me tomorrow times to it. I think I know which clamp on the that is.

Is not a bracket. The bracket is fixed with two screws.
