Question about Jura Capresso Impressa S9 Coffee Maker/Espresso Machine
I had the same problem and was about to take the machine apart when my girlfriend suggested I call customer service instead. Turns out when changing the filter, the air inside the new filter got sucked inside the machine causing a solenoir valve to airlock shut. You need to immerse the new filter in water before installing in the tank. All you do is keep pressing the steam button for 10 or 15 minutes at a time to jar loose the valve. Make sure you give the pump a rest every 10 minutes or so, or when the sound changes significantly so you dont burn it out. I did about 5 rounds of this yesterday and gave up, thinking I need to take it in for service....turned it on this morning for a few pushes and it worked. Be patient.

I had a similar problem. I took off the side and rear cover, followed the hose that comes from the steam wand to the rear of hte unit. It enters a solenoid made by ACL Italy. I dismantled the solenoid unit by disconnecting the two hose ends, removing the relay, and unscrewing the plunger unit (vertical pipe). The plunger unit internals should move freely up and down like a piston in a cylinder , powered by a small spring. In my unit, this plunger was calcified and seized. I soaked it in boiling water and pressed on it gently several times and it unstuck. I put it all back together again and presto! Good luck
