I recently completed a decalcifying cycle on my Jura Impressa X7 when troubleshooting an issue.With the problem now solved, a "decalcifying necessary" message is flashing.Is there a way to reset this?

I had the same problem, when I called their very helpful customer service, I was given these directions.
Take out the tray.
Inside the machine you can now see a flap hanging from the top.
Reach behind the flap, and you should feel a round object/filter. It has a little dimple sticking out in the middle.
Wipe the filter with a paper towel.
Put the machine back together, and voila you got your coffee brewing again.

Hi, if you havn't already solved this one, it has been caused by pulling the drip tray/ dump box out while the brew unit was still active. Switch off the machine and insert the drip tray without the dump box. Turn the machine back on and the brew unit should re align itself.

I had a similar problem. I took off the side and rear cover, followed the hose that comes from the steam wand to the rear of hte unit. It enters a solenoid made by ACL Italy. I dismantled the solenoid unit by disconnecting the two hose ends, removing the relay, and unscrewing the plunger unit (vertical pipe). The plunger unit internals should move freely up and down like a piston in a cylinder , powered by a small spring. In my unit, this plunger was calcified and seized. I soaked it in boiling water and pressed on it gently several times and it unstuck. I put it all back together again and presto! Good luck

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.

Hi,

This error is due to the coffee sludge built up in the system and needs you open the machine and clean it.

Note - Capresso recommends that you unplug the unit, wait a minute, and then plug in and turn on. Try twice if the first time doesn't work. If you still have a problem, call Capresso, and if your machine is under warranty they will repair it for you free of charge and even pay shipping both ways.

For cleaning instructions, let me provide you with a generic link that would help you :
