Jura E8 Expresso machine makes unusual noise when rinsing
My coffee machine stopped dispensing coffee during brewing and water during rinsing. I took the machine and brew group apart and replaced a faulty O-ring. I reassembled the whole machine. back
Initial problem is fixed, but now the machine makes this loud humming sound during part of the rinse. Also, the drawer gets pushed out every time when the coffee container is inside the drawer.
Here is a video capturing the sound:
Any ideas for troubleshooting? I notice that the brew group has a bit of play up and down (3 mm) - not sure whether that's the way it is supposed to be. I did not notice anything out of the ordinary looking at the brew group with the case open.
