Why the coffee is not coming out of coffee spout?

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 passage of water is not passing through coffee grounds. The coffee powder is dumped dry & water is bypassing the brew group and draining into the tray.
Causes:
1- Machine was not descaled. or descaled with automatic method only, as suggested by Jura.

2- There is accumulation of Calcium in the hydraulic system, generating back pressure. This reduces the pump pressure and water cannot force its way through coffee grounds.
3- Stop using filter cartridges. Turn the reminders off.

Solution:
Descale machine manually every three months. See link. Services Unlimited Inc Parts Guru Since 1988

Once coffee is extracted, its passage from the brew group to the cup is a simple gravity flow. There is no pressure to push its flow.
Layers of dried coffee clog the passage. In your machine this is advanced clogging or the water is not passing through the coffee and being drained into the tray.
To prevent this, use rinse cycle every day after coffee making is completed.
Descale the machine using Manual descaling method.
Do not use Filter cartridges as the same are expensive & ineffective.

There are two nozzles in front of the machine attached together, the nose of the bigger one on the top slides into the smaller one on the bottom. When it makes coffee, the spout outside the machine becomes lower so coffee can come out. When it is done making coffee, the spout goes up so water/coffee drips in the drip tray. If one of the nozzles breaks, the spout on the smaller one will not go down and the inside end is lower and coffee goes inside the drip tray. It has nothing to do with cleaning.

you hava to descall the machine

fill the tank with detergent and let the hot water run for about 15 seconds. Then turn off the machine for about 15 minutes. Then turn the machine back and let the hot water. Then rinse the water tank and fill it with clean water. Run hot water again to empty the tank. Fill clean water again and then you can put down coffee :)

Either the grind is too fine and the water cannot go through or the brew unit is blocked.

I have had this issue. First, check to make sure water tank is filled and correctly in place? Try descaling it; a kit came with coffee maker. (It just removes hard water build up, it may be blocking your water flow.) If that is not the issue, pull the tray where the used pods are dropped -Is it wet? Like the coffee is pouring into this tray rather than in your cup? If so, I have removed round silver plastic piece from around coffee spout,(gentle -do not crack it) then removed and washed the black spout, I even used a toothpick once, to remove the stubborn coffee ground, Once it was cleaned - it worked perfect. If you run water from the faucet into spout it should flow smoothly. I warn you though, not sure what this does to any warranty, but don't mess with my morning coffee! If the POD tray is not wet, I would tell you not that most likely your machine is not clogged by grounds, so you may not want to take snout apart. I hope this helps.

I had this problem and the spout was blocked you can push a small wire through the hole in the midle of the large white spout

Try this, if the machine has a pregrind door(usually on the top front) then use the button to tell it you are using pre grind coffee, if water comes out the spout this way then the grind on the grinder is too fine, if it goes out the drain then the coffee passage is blocked, remove the brew unit and check/clear tubes, also clean the spouts on the door of the unit.
