No water dispenses when making coffee, the hot water feature works fine. I have descaled twice

Hi,

Please double check that you're using a good water filter to lower the need to descale. Also, please make sure that you're refilling with cold water and not hot. And also double check that each espresso you make is being poured into the recommended size container by the manufacturer otherwise you would run into this problem based on the small size of the water tank (ie 40 oz).

Thank you.

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:
1- When new machine is set up, the owners click OK for use of Filter cartridges. This helps only to display reminders for replacing the filter.
2- The instruction also advises, regular use of Filters, eliminates descaling the machine. That is not accurate. Reminders for descaling are delayed or eliminated. This allows accumulation of Calcium deposits in the entire hydraulic and coffee system.
3- Cleaning tables recommended & sold by Jura do not remove Calcium deposits in the coffee/water passages. The automatic descaling method recommended by Jura also 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 & pointing to descaling the Brew group, coffee outlet tube and coffee dispensing faucet by using rinse cycles.

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

The problem is a very frequent one a small scale part have been moved and it stack to the water steam valve and it blocking it from closing completely. So when you make coffee the hose of water for coffee is in parallel with hot water steam wand and since the valve remains partially opened the water for coffee find easy escape from steam wand.

So we suggest to perform one more descale and it may need twice hopefully this small scale part to be dissolve a little bit more in order to pass thought the steam valve and thus the valve can close again completely. If you are not so lucky the part remain on the valve then only solution is to disassemble the machine thus clean the steam valve manually. In this solution you may find out that the valve o ring might be damage and thus the leak.
here is the link with steam valve parts and this the parts diagram of the machine and here many more for your machine

If you don't have a manual I hope this helps. You can make coffee without "Descale"ing it but it is recommended you don't go too long without doing it.

- Make sure that the filled water container is in the appliance.

- Turn the program selector to "On" with lighting and place a container under the hot water spout and another under the steam spout.

- Press the hot water button, turn the steam selector counterclockwise and dispense hot water until it flows in quiet, continuous streams.

- Press the hot water button again. Turn the steam selector clockwise to o, to turn off the water.

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

your machine is "Short Cupping"

It needs to be descaled. Even though the descale light might not be on yet, the descale light only comes on when it is in SERIOUS need of a descaling. You should descale once every 3 months.

Fill reservoir with distilled white vinegar and leave the machine on for 4 hours (make sure to turn off the auto off option).

after 4 hours, run the vinegar through the machine until the reservoir is empty. Refill with water and repeat twice. you will notice a difference right when you start running vinegar through.

The first descaling cycle likey dislodged some calcium which then found its way into a valve or water line. A second descaling cycle resolved the problem.

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.
