Question about Jura Capresso Impressa S90 Espresso Machine
I'm looking for a manual that explains how to take it apart so I can fix the leak. Seveal screws but there are some strange fastener not sure how they are ment to come off.
Here is how I solved this problem. I had a small needle nose vice grip, the 'nose' is about 1 1/2 inches long. I tried to clamp the oval shaped screw heads in the vice grip in a perpendicular manner, ie the vice grip was extending away from the side of the coffee maker. There is a recess in the plastic where the screw heads are seated so they are flush when tightened. The ends of the vice grip were slightly too large to fit in this recess. So I ground down the ends of the vice grip so it could fit in the recess and grip the oval end of the screw. After clamping it tightly, I used an adjustable wrench to turn the vice grip and the screw to successfully remove them. I replaced them with normal Phillips screws during the reassembly.

Tips for a great answer:
The mechanical engineer in me just had to solve the
problem. I unscrewed and removed the bottom plastic cover (3 screws) where the power card
goes into the machine and found the problem. The water from the reservoir feeds
into a white plastic priming pump. This priming pump is assembled in two halves
and one half has four plastic clips that hold the pump together. In between the
two halves is a rubber o-ring. Well, one of the clips was not secured and I
could see part of the o-ring protruding. This is an obvious source of leakage.
Either the pump was not properly assembled or it snapped out of place during
I unscrew the two screws that hold the priming pump in place, leaving the hoses attached, and carefully pulled the two pieces apart. Note how the magnetic impeller is installed and reassemble the same way. Use a small amount of vegetable oil to lubricate the o-ring and reinstall in the same place. Reassemble the to two halves, making sure the o-ring doesn't protrude, then snap the two halve together tightly. Screw the primer pump back into place then screw the bottom plastic cover back into place.
After this fix the machine no longer leaked and it brewed
a nice espresso. Everyhing seams to work find now.

There are many possible points that the leak can be.
All points of the water supply from water tank to the pressure pump then to boiler and finally to coffee group. All this are connected together with plastic or Teflon pipes with easy fit unions secure with clips
You need to disassemble the machine and work it without the side panels of course with extra care since power electrical cables are exposed.
In this way with a very good visual check while the machine is in operation you can identify the leaking point and fix it.

The problem is that the heated water is leaking out of the drip chamber. This is caused by the fact that they were to cheap to use stainless steel screws that hold the chamber top to the bottom. The screws have rusted and the hot water can escape the drip area and runs down next to a plastic tube that delivers the hot water to the top of the coffee maker from the heating element. To repair you have to remove two screws that are on the underside of the hot water drip area above the coffee filter. Then there are 3 tabs that have to be released and separate the cover that has the strength control from its base. When you pop off this cover, you will see the remains of 4 screws that are badly rusted. I used a small ez-out and drill to remove the remains. Be very careful to not drill the pilot hole through the top. I got lucky and was able to remove the screws and replaced them with stainless steel. An alternate method would be to use a food grade 100% silicon adhesive and glue the to back together. This method may leak in the future, so try to get the old screws out first.
I would recommend a MR coffee $30 to $50 models, on sale, for coffee before I would ever buy this European designed junk. I took this thing apart and just shook my head and said that you can tell things that aren
