    Press the P button. "Maintenance status (1/6)" appears on the display. Press the "Decalcify" button. Now follow the instructions on the display.

    Note: If "Decalcify" remains displayed for a long time, this means the descaling programme was started with too much liquid or water was replenished before the water tank was empty.

    If "Decalcify machine is displayed even though the CLARIS Blue filter cartridge is inserted, this means the machine was not changed over to using a filter in programming mode.

    Coffee taste and coffee temperature

    Coffee taste:
    Are you dissatisfied with the coffee taste? A poor coffee taste may be due to the following possible causes:

    • Grind setting: If your coffee tastes too weak, you can select a finer grind setting to extend the extraction time. If your coffee tastes too strong or too bitter, select a coarser grind.
      Please note: We would normally recommend a coarser grind for dark roasted beans.
    • Coffee strength: The coffee strength is not set according to your taste. Please note that you can select the coffee strength individually for each beverage you prepare (extra mild, mild, normal, strong and extra strong)
    • Filter cartridge: The descaling programme was performed with the CLARIS Blue filter cartridge inserted. In this case, remove the filter, insert a new one and change the machine over to using the filter in programming mode.
    • Coffee beans: Your coffee beans are "sour". Empty the bean container and fill it with fresh beans.

    Coffee temperature:
    Is your coffee not hot enough? A coffee temperature that is too low may be due to the following possible causes:

    • Temperature setting: The coffee temperature has not been set to "High" in programming mode. Please note that the temperature can be set individually for each coffee product ("Normal" or "High").
    • Machine has built up limescale deposits: If you are not using a CLARIS Blue filter cartridge, the machine might have built up limescale deposits. Check the water hardness, set the machine to the correct water hardness and perform descaling.
    • Tip: Prewarm your cup!

    Display and text messages

    "Decalcify machine" is displayed even though you are using the CLARIS Blue filter cartridge.

    Reason: The CLARIS Blue filter cartridge has been inserted without the machine being changed over to using the filter in programming mode.

    Remedy: Remove the filter from the water tank and run the descaling programme. Then insert a new filter and change the machine over to using the filter.

    "Descaling"is displayed for a long time.

    Reason: The descaling programme was started with too much liquid or fresh water was replenished too soon. All the water in the water tank must be sucked out during the descaling programme.

    Remedy: Run the descaling programme again with 0.5 l water.

    Milk foam

    If the milk is not frothed, this means the Professional Cappuccino Frother / Professional fine foam frother is blocked. Remove the frother and clean it thoroughly.

    • Please note that the frother must always be cleaned well after preparing milk or milk foam.
    • Tip: Use the special JURA Cappuccino Cleaner for cleaning.
    • Note: The fat content of milk does not influence frothing. It is also possible to use low-fat milk.
    • Tip: If you are not using a CLARIS Blue filter cartridge, run the descaling programme because calcium deposits in the pipes can impair steam preparation.
