". It worked fine,
however I decided to
create this instruction. The two pictures on the upper German page show the
state of the machine after 1800 cups of coffee and the normal cleaning program.
If you have any questions about this instruction, please name the number of the
picture as a reference. It shows when you rest the mouse on it.
At this point I want to thank you for all the friendly emails I receive. I enjoy
them much and they encourage me to keep these pages in good shape.
General Information
At the first cleaning (11/18/2002), when these pictures were taken, I
replaced all three O-rings with the ones from the "Rundum sorglos Paket XXL".
Then I had to apply lubricating grease about every 200 cups. I was lucky to save
the original O-rings after that first cleaning. Later
(04/14/2003) I replaced the two bigger O-rings with the original ones.
After that change, the normal interval rates returned (01/05/2004 : 750 cups without
any service).
A technician from the Jura service gave the hint to use lubricating grease
for drinking water fittings. It is compatible to the O-rings, hot water
resistant up to +180°C and you can get it from any do-it-yourself store at a
reasonable price. He suggests to put lubricating grease only on the O-rings and the long gearwheel.
All other moving parts do not need lubrication, as plastic slides on plastic. Grease attracts coffee
powder that would slow down the machine.
Picture 00
Andreas uses an old toothbrush and the small vacuum cleaner nozzle for
cleaning and reapplying lubricating grease through the pre-ground coffee filler
funnel (without dismantling the machine).
Rainer told me, his S95 has Torx screws instead of Philips screws.
Sven bought the replacement for his boiling part at the online shop of
http://www.trepesch.de. Until further
notice, I show this link with permission of the Trepesch GmbH.
Rainer bought Viton O-rings at Mordhorst + Bockendahl from Kiel. He paid
€13,= for 2 rings 1.8 x 3.9, 2 rings 3.5 x 37 (upper cylinder) and 2 rings
3.5 x 35 (lower cylinder). The rings are heat resistant and will run for a long time.
Andreas Krietsch permitted me to
advert his offer (01/05/2004)
O-ring set (2x 36.1x3.53mm, 1x 3.4x1.9mm) €2,= +
postage for letters €2,= (against prepayment)
Further details may be requested by
email.

Picture 01
We start here. Left of the S95 you can see the "Rundum sorglos Paket XXL"
of XXX*. On the right side you can see the tools I use. A Philips
screwdriver and a normal screwdriver to open the latches. The
Long-Nose pliers on
the right side is used to pull the clamp. The small pliers on the left side
isn't used at all. You need to vacuum clean with a small nozzle to
get rid off the coffee residue.
Picture 02
First remove the water tank, then the drip tray, the pre-ground
coffee filler funnel and the cover for the bean container. You have to
pull off the two knobs "grinding selector panel" and "selector
panel for coffee or hot water". When you remove the two screws you can
remove the heating plate.
Picture 03
Now it's time to remove the top cover of the machine. Please be
careful after taking the screws out with removing the panel.
Picture 04 |
The next step is the front door. You have to
remove the screw in the area of the drip tray. Please regard the small nib
on the right side, that fits into the door. You have to watch this when
you reassemble the machine. It must fit into the whole at the door. By
the way, in the left lower corner of this picture you see the two plugs for
the contacts shown in Fig. 8 of the Jura Instruction for use. Therefore the
contacts are on the rear side of the drip tray. |
Picture 05 |
Remove the "selector panel for coffee or hot
water" from the front door by carefully inserting a screwdriver between
the two clips
on the door. While you
topple the "selector panel for coffee or hot water" backwards, you can pull out the
pivoting nozzle for hot water/steam. |
Picture 06 |
Now it is possible to open the door a little
farther in order to remove the hoses from the coffee- and tea-spout. You have to bend the clips a
little. But take care again. |
Picture 07 |
Now we are done. The
door can be opened
completely. When you open the door towards 90° the wires are stretched and
there is a dead stop. I suggest to avoid to open it further on. ;-) |
Picture 07 a |
Kerstin, this is the way to unmount the coffee dispenser. Unlock the four clamps at the door.
|
Picture 07 b |
The coffee dispenser is disassembled by lifting the latch. With this you seperate the upper part from
the lower part. The insert has to be removed from the lower part.
|
Picture 07 c |
Picture 07 d |
Picture 07 e |
|
Picture 07 f |
Picture 07 g |
Now it is possible to clean the lower part. |
|
Picture 08 |
Although you might not
believe it, there is a
clamp at the tip of the arrow. This clamp fixes the hose into position and is removed by
pulling it to the front of the machine. |
Picture 09 |
As you pull the hose out, an
O-ring
stays inside. This is the O-ring, I replaced with a new one. Rainer told
me, that his machine has a ring of copper and it had verdigris on its surface. He used
hot air (100°C) to heat the area. Then he could remove the hose. |
Picture 10 |
Two more clips to carefully bend, with a
screwdriver, to remove the tiny pipe at the top of brewing unit. |
Picture 11
Now we have to remove the brewing unit. It is fixed with three
screws. When
these screws are removed, the whole part can be slid down and to the left to get it from
behind the "selector panel for coffee or hot water".
Picture 12 |
Picture 13 |
Here it is!
Picture 14 |
The long gearwheel can be slid off to the top.
CAUTION: The gearwheel fits in one way only. You have to remember it's
position. The cover above the big white gearwheel, opposite to the long
gearwheel, is clipped in. The guiding plate must be bend outside
at it's top to loosen it. Now you can slide it down to remove it. |
Picture 15 |
Pull off the cap to the top
by slightly bending all four corners outward to release the notch. The
angled plastic pipe is pulled off the vertical pipe. The position of the
vertical pipe defines the position of the cap during reassembling. |
Picture 16
|
Picture 17
|
The front and the rear cover is removed by opening four
clips for each cover. Rainer, you are right. You should start with the fourth
clip, that is not shown in these pictures. Be careful, the metal spacers from the outer guiding
of the topple mechanic will fall down now. They must be placed back during
reassembly.
Picture 18
|
Picture 19
|
Picture 20
|
To
remove the lower water supply from the brewing unit, the topple mechanic must be
moved to the shown position. Turn the big white
gearwheel. Be careful with the direction. The topple mechanic can be moved in
one direction only. When the topple mechanic has reached the shown position the
lower water supply shall drop down without any force.
Picture 21 |
The water supply can now be
removed from the slider. CAUTION! The white plastic part will jump off
immediately. I used the picture of the cleaned piece to be able to show the
details. |
Bild 21 a |
Once I had a service for my brewing unit. With that change I got this water
valve. It combines more parts, but it's more easy to clean. When the valve
is removed, it falls into peaces.
|
Picture 22 |
Now remove the two snap
rings from the axis of the topple mechanic. Use a screwdriver
to pull them off. The next step is to push the axis through the bearing to
one side. In our machine one end of the axis was covered with rust. I had to
use a wooden punch and a hammer to get it out. But I had to be careful also,
plastic parts break easily. The brown plastic parts of the
topple mechanic can be turned in such a way to release the tube with the
pusher to the top. Now the lower part with the six gearwheels must be
twiddled out of the black plastic part. Without using force it is a little
difficult, but it is possible. |
Picture 23 |
The two side plates that cover the big white
gearwheel can be pulled out off the bushing right below the gearwheel. Now
the gearwheel is free to remove the brown inner pieces of the
brewing unit. |
Picture 23 a |
Picture 23 b |
The slide can also be disassembled.
The coffee pipe can be removed by turning it. With this the spring
and the plug are released. The filter is released by removing the
screw. Robin, here is one of the large O-Rings.
|
|
Picture 24 |
That's it. Everything is disassembled and you
can start to clean each piece. I used a vacuum cleaner, hot water and a
brush with plastic bristles. |
Picture 25 |
We start with this piece. It is the lower
water dispenser of the brewing unit. You put an O-ring with a thin cover of
lubricating grease
into the short connector. The long connector will get the new O-ring
later. |
Picture 25 a |
Picture 25 b |
If someone is having this type of water valve, it is important that only one side is
having a notch. At this side the output to the drip pan is placed fitting into the notch.
|
|
Picture 25 c |
This picture is showing all parts of the water valve unit. |
Picture 26
|
Picture 27
|
Picture 28
|
On the
front of the slider fit in the long connector of the water dispenser. On
the rear of the slider fit in the angled pipe. Both pieces are fixed with a
clamp.
Picture 28 a |
Now the cylinder with the lower slide is
assembled. This picture is showing all parts.
Robin, here is the second large O-Ring.
Karsten, these pictures are showing the correct assembly of the parts. It
fits when the part with the gearwheel is moved to the top most position
(towards the cylinder) to insert the slide. |
Picture 28 b |
Picture 28 c
|
Picture 28 d
|
Picture 28 e
|
|
Picture 29 |
The smaller O-ring
is mounted on the lower pusher of the brewing unit. Put lubricating grease
into the notch to cover the whole O-ring. The pusher is placed inside the
tube that will hold the coffee powder. |
Picture 30 |
Now you twiddle in the
lower part with the six gearwheels. It's a good idea to put one arm into
the opening as shown in the picture. The inner the metal
spacers get a cover of lubricating grease before they are mounted.. |
Picture 31 |
With the next step you place the tube with the
pusher into the six gearwheels. It is important that the pusher can reach
both end positions. Planar with the upper edge of the tube and with contact
to the stop position at the lower end of the tube. If it doesn't match, the
pusher will drop of the upper end of the tube. Now put in the axis and
fix it with the two snap rings. To ease the next remove of the axis, put
little lubricating grease around each end. |
Picture 32 |
At this point you can check the movement of
the topple mechanic. It is important that the nib fits
into the notch. Otherwise the water dispenser isn't sealed when the brewing
takes place. Unfortunately the brown parts can also be put in in the other
direction. |
Picture 33 |
The larger O-ring
is mounted on the upper pusher of the brewing unit. The pusher is placed
inside the screw thread. This notch needs lubricating grease too, to cover
the O-ring. After that, you must move the topple mechanic into
the shown position. Now you place the metal spacers on the outer guiding of
the topple mechanic together with some lubricating grease. |
Picture 34 |
Screw the big white gearwheel onto the
thread and push the two side plates into their bushing right below the
gearwheel. Don't lose the metal spacers during that step! |
Picture 35
|
Picture 36
|
Snap in the two side covers.
|
Picture 37 |
Snap in the angled pipe into the notches of
the cap. As it is symmetric, there is no wrong way to do it. |
Picture 38 |
With the mounted angled pipe, the position of
the cap at the top of the brewing unit is defined. Each four corners must
snap into a notch. |
Picture 39 |
Now slide in the long gearwheel
and snap on the guiding plate. With the
black cover plate the horizontal pipe is kept in place (not shown in this
picture). As mentioned earlier, the long gearwheel fits in only one
direction. At this point the mounting of the brewing unit is finished. |
Picture 40
The brewing unit is placed into the machine and fixed with three crews.
Picture 41 |
This step is a little difficult. The lower
water hose with the O-ring must be inserted and fixed with the clamp. To
prevent the copper ring from getting verdigris on its
surface, cover it with a little lubricating grease.
By
the way, this is the small O-ring I replaced with a new one. |
Picture 42 |
The O-ring inside the upper water supply gets
a little lubricating grease and the pipe is connected and fixed
with the two clips. |
Picture 43 |
The two O-rings get a
little lubricating grease too, and the
hoses are reconnected with the coffee- and
tea-spout and
fixed with the clip. |
Picture 44
|
The two O-rings on the pivoting nozzle for hot water/steam get a little lubricating grease and the
nozzle is pushed into the "selector panel for coffee or hot water". The "selector
panel for coffee or hot water" is fixed with the two clips at the door.
|
Picture 44 a |
Picture 44 b |
For Christian and Armand I add detailed pictures of the selector in case someone has removed all hoses.
|
|
Picture 45 |
Now close the front door. Please take care
of the nib that must fit into the notch in the wall. Otherwise you can not
close the door. The door is fixed with the shown screw. |
Picture 46
The
top cover of the machine follows with the five crews ...
Picture 47
... and the heating plate.
Picture 48
Put on
the knobs, place the pre-ground coffee filler funnel and the water tank and you are ready. The
coffee machine is in one piece again.
XXX* suggests to run the cleaning program once to remove spare
lubricating grease. I have done this without a cleaning tab and I didn't notice
a difference in the taste of the first cup of Espresso. Now it is working again
and everyone is pleased.
Congratulations! You have earned the official
do-it-yourself certificate!
The ones of you, who own a Windows Mediaplayer, can listen to the sound of
the cleaning program:
