In an effort to control the cost of things that can typically
go wrong with a Super Automatic Espresso Machine, this
documents the critical part of taking one of these apart.

If you are handy and can fix common household items,
and you have the necessary tools, it really isn’t that
difficult. This detail to fix the Ceramic valve is
academic. If one needs the comlete valve, call
215-361-7000 to order one.

Tools needed:
• Screw drivers: standard blade and torque heads
• Specialty screw driver head for Jura “oval” screws that
hold the unit housing together
• Needle nose and standard pliers
• Light
• Patience
If you haven’t removed the housing before, the steps
for this are on the next page. These steps should help
you.

Housing Removal:
1. Unplug the unit. Remove the tray. Empty the bean
hopper.
2. Place unit on clear, accessible surface.
3. On the back of the unit, the Jura logo can be spun
counter clockwise about a 1/8 turn and removed.
Fiddle with it a bit if it doesn’t seem to want to move.
Trust me, it does turn.
4. Take your specialty “oval” head bit (can be purchased
on ebay from juracapressodoctor) and remove the
two screws holding the back panel on the unit.
5. Slide the back panel down slightly, then it should
come off the unit easily.
6. Now, the right side panel should be able to be slide
backwards slightly. If you inspect the back panel to
understand how it “slides” into the slots of each side,
you now understand how the right side panel is fitted
to the top. Be gentle and patient and it should slide
back and then easily removed.
7. If needed to facilitate removing the right panel your
first time, you can remove the entire top of the unit
by taking the three torque head screws out located:
1. Under the water tank lid near the front of unit
2. Under bean cover near right side
3. Under small cover behind the water cover

inspection, there is
a small drain hole
here, presumably to
avoid water build up
internally when the
seal eventually fails.

Notes: Even though the replacement valve comes with pre-attached hoses (2 of
5), it was far easier to unfasten them from the valve than detatching from the
various locations on the machine. In particular, the long hose that connects to the
boiler, I tried to detach the hose from the boiler but, after multiple attempts, the
hose could not be loosened from the boiler.

already been removed.
After the screws are
removed, these to

Pulled the seal with a screw
driver, came out with a very
gentle tug.
Very Important orientation to notice
here. On the black slotted disk, you will
notice two slots, one straight along the
center, the other a semi-circular shape
along the bottom. When reassembling,
this disk must be reinstalled in the same
orientation as this piece spins by the
motor and allows water to flow between
the correct holes (of the 5 in the
assembly).

This is the internal part that probably needs to be replaced.
Clean all components thoroughly, then apply thin film of
lubricant.

Having problems steaming Milk hot?
Use Milk flow restrictor (part #26151) to steam Milk Hotter
Eliminate small size Milk Carafe. They are expensive and need frequent refilling,
intense cleaning & replacement of damaged or lost rubber connectors.
Use of Milk flow restrictor with 15" Silicone tube Order part # 26151-S15
The restrictor is not good for use in Pannarello frothers & other older Jura
models in which frothers do not use a Milk container to draw milk.

Extensive Calcium deposits are seen in almost every Jura machine we open for repairs.
Jura Filter cartridges are preventative & ineffective. Filters cartridges remove chemical
taste in water & do not prevent Calcium build up in the hydraulic system.
The Brita filter installed on the kitchen faucet works better than expensive Jura filters.
Calcium sediment inside the machine causes the following problems:
(1) reduces flow of water with full or partial clogging.
(2) generate back pressure in the Hydraulic system & cause internal leaks.
(3) reduce pump pressure for coffee extraction & water collects in drain tray instead.
(4) error codes 4, 8, & "Fill water" will display & force expensive repairs.
We recommend Deactivating the electronic reminders for change of Filter.
Descaling is best done manually, every two or three months.

Order Best descaler (#DSC-6) from our online store for effective & authentic descaling.
