Does anyone know how to take apart Jura Impressa
I hope this Jura F90 dismantling guide may offer some clues for
your E-series machine.
Before you start remind yourself of the risks. In case of a mess up,
below I've listed a firm selling spares in Europe. In the UK it is
assumed that it you can afford the BMW of coffee machines, you can
afford to fix and service it too. However I haven't tried any of the servicing firms so they, and yours could be really, really helpful and cheap.
You will need about 4 different torx; hexagonal and possibly unique screwdriver
bits to remove all screws. A plastic pry tool (used for mobile phones)
will help where plastic lugs hold on the side and top panel.
Empty beans; water store and remove the waste tray. On the Jura F90 use
pliers to undo two oval headed screws at the back at the top. You'll be
able to remove the top panel after using a pry tool to disconnect two
lugs at the front edge.
You don't want to dismantle the coffee grinder and its hopper. Retain
the hopper's rubber seals or glue them in place before you lose them as I
did. Four screws hold the central back panel. Slide out a white key
underneath the machine (can't recall how crucial this was).
The side panels are removed by using a pry tool to release lugs all down
the edge where these panels meet the front. Work slowly to manoeuvre
the side panels off. If you simply want to clean the brewing unit
externally then just remove the panel on the water side.
Find the water inlet just where the water tank sits. A screw here allows
you to remove a plastic piece - but take a photo of how it slots in.
This gives access to the lower end of the brewing unit. If the plastic
piece is still it the way, you can ease off the water pipe from the
water inlet and put it aside.
A number of different brands are made by one firm and branded. Thus the
guts of these machines are similar. The brewing unit in the Jura F90 is
almost identical in many machines. The screws and attachment places are
different. The water inlet and valve are different. Cleaning the parts
you can now see may fix a Malfunction 8 without removing and dismantling
the brewing unit. The machine is partly operable in this state - cover
the exposed electrical connections and remind yourself of the danger
here. Thus you can switch off the power when the brewing unit's white
wheel is at the top and then at the bottom. In this way you will get
access to places causing any jam. You might just need to clear the inner
chamber and path for two plungers with two large O-rings. You can see
the water inlet nozzle with its o-ring which can perish and cause coffee
or water to go to waste. Silicone grease only where the O-rings slide.
Leave the other plastic parts ungreased. As I said you might get away
with not disassembling the brewing unit. You can however buy a
maintenance kit or a new brewing unit from the shop below.
You will want to avoid removing the nylon water pipes - unless they're
actually leaking. These pipes are held in place with a wire clip (remove
with a flat head screwdriver). Ease the nylon pipe with its brass
collar out of its socket. The pipe goes into an O-ring in the pipe's
socket - this might fall out.
Removing a brewing unit is like removing a car engine. The link at the
shop below has a pdf (Anleitung_Jura_E.pdf) There is no need to force
anything. On the Jura F90 the brewing unit is removed by undoing two
obscure screws from the coffee grinder side. I had difficulty removing
these and I wish I had taken time to find the right tool instead of
wearing down the screwhead.
On the electronic side there's an optosensor (encoder) unit held in
place with a steel clip. You might remove this to access one of the two
screws. At the bottom of the brewing unit, the water inlet valve is
fixed to the machine with a single screw. Next, on the water tank side,
you'll see two lines of screws that hold the assembly in place. The
middle screws of the screws allow you to separate the unit from the
gears. The top two holes don't have screws.
Coffee machine spare part supplies are not as common in the UK as they
are in mainland Europe. You'll find this web useful because of the
pictures: www.kaffeemaschinendoctor.de is a German web shop for machine
spares AND there's a pictorial of how to dismantle the Jura F90 as a
pdf. Google will almost translate it). Juradoctor.de also carry lots of
spares but don't seem to ship to my country.

Error code 8 appeared and now cannot get basket
The machine did not complete its cycle, either while finishing a brewing cycle or a cleaning cycle. This is caused because the motor is not strong enough and overheated. I think it is a design problem, but there is a "work-around" solution.
First, to put basket back, look inside opening. You will see a flap at the back of the opening. This flap is down and is what is preventing insertion of basket. Take only the grounds basket. Tilt the grounds basket and insert it so the back end of basket goes under the flap. Then level out the basket. Note the flap is now inside the back end of the grounds basket. Holding the basket up and level, re-insert the drip tray and the basket holder underneath the basket. These should now slip into place.
The "work-around" solution is to let the motor cool down. Unplug the machine for at least 30 minutes, then turn unit back on, and the cycle should complete because the motor is now cool.
I notice this error 8 happens mainly when the voltage from the Hydro Utility is low. This happens during peak electricity usage hours. So, to clean your machine, do it on the week-end during the daytime either mid-morning or mid-afternoon.

Impressa e9 won't turn on,
these coffee makers and, many kitchen heating appliances have a small thermo fuse in between the one side of the plug and, your heating element it looks like a metal can with one flat and, one pointed end Radioshack sells the fuse
