General Jura Decalcification/Descaling process

Before you start the process, we recommend you have the following at hand:

What you need?

We recommend that since most of South Africa’s water is quite soft, that using an in-line filter is not really necessary. But this does mean that every 220 litres or so you will need to descale or decalcify your Jura.

  • Jura descaling tablets.
  • Some way to measure 500ml of water.
  • Optional: a vessel for the flushed water (you can also use the grind bin).
  • Water.

  1. Assuming the machine is asking to be descaled, press the button to start the process. You can also force the machine to run the process if you want, see manual for details.
  2. The machine will say something like Empty Tray.
  3. Remove any milk frother that is removable from the machine.
  4. Remove the tray from the middle of the machine, and clean. If you want, you can then use the grinds’ container to catch the flushed water as part of the process, so you can then put the tray back without that.
  5. Machine with probably say something like Solvent in tank.
  6. Remove the tank save the water for later, either in the tank or in a 500ml vessel, completely dissolve the descaling tablets (3 of them, or 1 set)) in the 500ml water.
  7. Wait until the water is clear.
  8. Then place the tank back on the machine.
  9. The process will now start, and may have some instructions. It takes around 30 mins.
  10. Once all the solvent water has gone through the machine, it will say: Empty Tray again.
  11. Empty the tray, clean.
  12. The machine will say Fill Tank.
  13. Remove, clean and fill the tank and return it to the machine.
  14. Now it will remove the solvent from the system. This takes about 10 minutes.
  15. Done.

Jura Video

Find below the video Jura made for descaling the Jura E8.


Coffee tastes funny: Either the tank was not cleaned properly or the water that was used to flush the system after the descaling process, still had some descaling stuff in it.Repeat the process (without using a tablet) or run about 500ml water through the machine.
Repeating: The machine wants to run the process again.This occurs when less than 500ml water was used as part of the process. Repeat process but do not use the tablet, merely have 500ml in the tank for it to clean the machine with.
Pills not dissolving: I added the pills to the water, and they are not dissolving.Make sure you use the correct pills, they are square, not round.

Hint: it does help to use lukewarm water to dissolve the tablets.

    I have descaled my Jura E8 coffee machine but when finished it says over and over to Empty drip tray which I have done about 8 times but still says Empty Drip tray , it won’t go back to the normal coffee list.

    1. Hi, the contractors at the back of the tray have liquid on them. Wipe them and in between with a paper towel. You may also need to do the same with the connectors in the machine. You will have to stretch into the machine and wipe them down. You can also use a hair dryer to blow inside to dry them out. If still giving an issue leave the tray out for an hour or two. The sensors are very sensitive. Try keep water away from them when pouring out the water in the tray.

    Do you leave the filter in when descaling, and if so does it need to be changed after descaling?

    1. As you need to add the descaling tablets into the water tank, and the filter then will block the cleaning liquid it is recommended to remove the filter. If you have a smart filter (grey) the machine will detect that the filter is removed, the white and blue filters it does not. Make sure to never over use a filter as this can damage the pump.
