Question about Jura Capresso Impressa S90 Espresso Machine
Short answer: You need to lubricate the plunger mechanisms in the brew unit.
Long answer: There are two rubber o-rings - one in the base of the brew unit and on the plunger that descends into this to form a seal. There are great instructions on how to take apart, clean and lubricate the brew unit here:
...but they are not for the faint hearted.
There is also a cheats way too which I use.
First, get some SILICONE lubricant. It needs to be Silicone. You can get it from ACE for $3.
Remove the door / funnel mechanism from the powder inlet - it just lifts out.
Usign a flashlight, take a look inside where the coffee grind goes. You will see a cylinder with a plunger mechanism at the bottom. You need to lubricate the ring on the bottom plunger and the tope one (which you cant see this way).
Use the flashlight and a knitting needle and place some silicone at the base of the plunger - you will see what I mean when you look inside with the flashlight. Also put some around the top lip of the cylinder (for the upper plunger). It is sticky and messy.
Press the "rinse" button.
You can do this a few times. The silicone will not affect the taste of your coffee. I tend to put a liberal amount in and then wipe off the excess with a kitchen towel on the end of the knitting needle.
This is fiddly, but it works. I do this in between complete disassembly, which I do about once per year using the above instructions. If you need to replace the o-rings, you should be able to find suitable replacements at a local hardware store but this is a trial-and-error process, I'm afraid. I have never ordered the ones linked to on that page.
Hope this helps.
Now, if only I could work out how to fix the leak from the rear....

Same problem here also.
Any body got the order of pulling one of these things to bits. I want to have a look at the works. We have sent our S9 away about 4 times to get this fixed - 2 new brew units, 2 'O' ring replacements. It works for about 4 to 6 months after we get it back then starts taking longer to dump then binds up and shows an error 8. Turn the power off for awhile, resart and it works again for a couple of cups. I've taken the top off, looks like a need a 3mm socket for the 2 fixings on the lower back.
