Cannot get any water or coffee to come out of coffee tubes. Machine descales fine.

Fortunately the problem you describe is not model specific. All Jura machines in the series C, E, F, J, S & Z models have the same problem. The Jura recommended maintenance is insufficient or erroneous. Here is how it occurs:
1- When new machine is set up, the instructions advice the owner to set up OK for use of Filter cartridges. This set helps only to display reminders for replacing the filter.
2- The initial set up instruction also advises that with regular use of Filter, descaling the machine will not be needed. That is really not accurate. Consequently, the reminders for descaling are delayed for over one year or more. This causes serious consequence with accumulation of Calcium deposits in the entire hydraulic and coffee system.
3- Use of Filters alone does not prevent Calcium deposits. Cleaning tables recommended & sold by Jura do not remove Calcium deposits in the coffee/water passages. The automatic descaling method recommended by Jura leaves the coffee side of the machine unclean. The error message in your machine is due to Calcium deposits in the Brew group, coffee outlet & the faucet dispensing coffee in the cup. I suggest all Jura machine owners should manually descale machine. Manually descaling includes use of 6 to 10 rinse cycles with descaling solution in the water tank. The error message "Clean Machine" is accurate. This error message is pointing to descale the Brew group, coffee outlet tube and coffee dispensing faucet by using rinse cycles.

After the rinse cycles are complete, refill Descaling solution in the water tank & continue descaling the rest of the machine by using hot water dispensing function, ½ cup at a time until the tank is empty. Finally, give a final flushing of machine to flush out remaining descaling solution inside the machine.

Hi
Yes it may need descaling - deposits like calcium etc from 'clean' town water will build up in the machines boilers and tubes over time - that's why we descale them regularly - even if they don't get a lot of use.
Suggest you get some proper descaling liquid, not vinegar or CLR, read the manual on how to do it (download it off the net if you don't have it). ( it takes a little while as the descaler has to eat away those deposits and the machine will pump a little water out, then wait for a while, pump a little more etc until its finished the process)
Make sure your filter in the coffee dispenser handle is clean as coffee itself will build up and block those tiny holes if the machine is not porperly cleaned each day when used.
Cheers

Not too sure sort of same issue on last machine i descaled it and it worked on this one not so lucky so looking for answers too, if you often descale your machine then it wont be this if you havent descaled it for some time, then this could well be your issue, pending on how knowlagable you are, you can take to bits, put CRC or neat descaler into the tubes, there is a little spring clip type of holder you need to take out before removing small tube, use a serynge and squirt some neat descaler into tube and if possible where it came out of, few time before my main issue was at the front water dispenser part, so if you can undo a tube from the furthest point from this then put in descaler attach tube again, put back to gether leave for a little to get through then turn on and try to get hot water out, if so the coffee side will probably work too, but before you have a cup fully descale the machine and rinse through a few times then try a cup

HI
There are a few things that can cause this. If it brews without the portafilter in, then your coffees is too fine or you have a blockage in your basket if it has a ring in the bottom. If it doesn't brew with out the portafilter in, then you have a blockage in your brew head. There is a screw that holds in the dispersion screen. Above that is a larger screw that holds in a check valve. if you can get the check valve out see if water will run through. If not your blockage is in this tube. run a heavy wire up this tube for about 4 inches. Twist the wire as you go. Test to see if you can get water through. If so reassemble and do a descale through both the wand and brew head. Use a strong descale the first time and then do a second. Descale 2 to 3 time a year to prevent this.

Yup, it sounds like you have a leak !  When the spoon is locked in place, the coffee is preventing (blocking) the water from flowing freely, and it simply finds an easier path, through a hole or loose fitting above the spoon... Depending upon your skill level, you may want to have a look inside the machine and you should be able to see where the leak is.  If it's a hole in a pipe/tube, the pipe/tube will probably need to be replaced (maybe it can be repaired...), and if it's a loose fitting, you can try to tighten it.  It might have come loose due to the vibrations from the pump. Another possibility is that you have a lot of scale built up in the system.  If you've never descaled your machine, you should do so regularly using coffee machine descaler or "CLR" available at hardware stores.  If you've ownded your machine for a while and never descaled it before, run the descaler 4 or 5 times to give it a good cleaning and then do so according to the instructions (I do mine every couple of months but I don't use my machine every day).  If you use unfiltered tap water, the scale will build up more quickly, specially if your local water is "hard".  Consider using filtered water to reduce the buildup of scale.

Hi,

Try this:

Standard descaling
Switch off the machine.
Pour a descaling product into the water tank.
Switch the machine on to the programming mode(see below). Place a large container under the steam/hot water dispensing tube and open the steam/hot water knob slowly, turning it counterclockwise.
Turn on the machine by pressing the main switch and let the descaling product flow out of the dispensing tube for approx. 1 min.
Close the knob again.
Turn off the machine with the main switch and let the solution take effect for approx. 5 minutes.
Repeat this procedure two or three times, to allow all of the descaling product in the water tank to flow out of the dispensing tube.
As soon as descaling has been carried out, rinse the tank thoroughly and fill it with fresh water.
Switch on the machine and let fresh water (approx. 2 l) flow out of the steam/hot water dispensing tube in order to rinse away residue.
The machine is now ready for operation.

When the machine is on, the warning light switches off automatically, by pressing the steam selection button for at least 5 seconds.

To enter the programming mode, turn the machine
off with the main switch.
Press steam , espresso coffee and the
main switch at the same time.

Release the buttons.

Hope this will help you.

Hi,

Warning! Never use vinegar as a descaling agent. You can use any commercially available non-toxic, non-harmful descaling product for coffee machines.

Descaling is necessary every 2 months; should water be very hard, descale the machine more frequently. The machine must be on; it automatically controls the distribution of the descaling solution.

1. Switch off the machine.
2. Fill the water tank with the descaling solution.
3. Place a large receptacle beneath the steam tube.
4. Switch on the machine.
5. Open the knob.
   The descaling process starts.
6. Dispense the descaling solution into the receptacle.
7. After about 30 seconds close the knob.
8. Switch off the machine and remove the receptacle.
9. After 10 minutes, follow instructions 1 to 8 to the water tank is empty.
10. Rinse out the tank and fill it with fresh drinking water.
11. Place a large receptacle beneath the steam tube.
12. Switch on the machine.
13. Open the knob to rinse.
14. If the receptacle fi lls, empty it.
15. When no water is left, turn the knob to close the valve.
    Remove the container.

After descaling the machine, reload the machine circuit. Install the cartridge filter again in the water tank.

THIS HAS NOTHING TO DO WITH THE COFFEE. This has to do with water filter system and most importantly descaling of machine, as over time the metals in side machine and tubing get a mold type build up. Its a chemical reaction from the water and tubing and the coffee and metals. To 100% solve this, descale the machine with water and vinegar mixed. Do this a couple of times and use bottled water to fill water tank if you do not have a good water filter tap system. I have been the espresso business for over 16 years with 4 locations, and it has nothing to do with the coffee. If it was the coffee or poor coffee it would tasted burned or bitter, but NOT tasting like metal.

Please rate my solution as you see helpful, Thanks Mike Espresso Expert

it started to leak after the descaling and the water that leak is the water very hot you might have a leaky boiller in the descaling process calcium in the boiller melt and if you have bad seal =leak in the boiller. if you use a descaler product and if you use vinegar that might be y you have no steam vinegar remove calcium in little pieces and sometime those pieces block the machine descaler product melt the calcium thanks for using fixya pierre
