Product Resource Details

Filling the bean container

  • Remove the aroma preservation cover of the bean container.
  • Remove any dirt or foreign objects from inside the bean container.
  • Fill the bean container with coffee beans.
  • Close the bean container.

First-time use

When using the machine for the first time, you can choose whether you want to operate ENA with or without the CLARIS Blue filter cartridge. If the water hardness is 10 °dH or more, we recommend using the filter cartridge. If you do not know the hardness of your water, you can find this out first (see Chapter 1 ‘Preparing and using for the first time – Determining the water hardness’).

Determining the water hardness

You can find out what the water hardness is by using the Aquadur® test strip supplied as standard.

  • Hold the test strip briefly (for one second) under running water.
  • Shake off the water.
  • Wait for about one minute.
  • You will then be able to read the degree of water hardness from the discolouration of the Aquadur® test strip and the description on the packaging.

The water hardness can now be set.

Connecting milk

Your ENA creates fine, creamy, feather-light milk foam with a perfect consistency. The most important requirement for frothing milk is a milk temperature of 4–8 °C. We would therefore recommend using a milk cooler or a vacuum milk container.

  • Remove the protective cover of the dual spout.
  • Connect the milk pipe to the dual spout.
  • Connect the other end of the milk pipe to a milk container or immerse it in a milk carton.


Coffee tastes best served hot. A cold porcelain cup cools the beverage – and impairs the taste. We therefore recommend prewarming the cups. The full coffee aroma can develop only in prewarmed cups. You can purchase a JURA cup warmer from your specialised dealer.

You can make permanent settings for all products in programming mode (see Chapter 4 ‘Permanent settings in programming mode – Products’).

Regular maintenance

Carry out the following maintenance actions regularly or as required:

  • In the interests of hygiene, we recommend changing the milk pipe and interchangeable milk spout on a regular basis (approximately every 3 months). Replacements are available from specialised dealers.
  • Clean the inside of the water tank, e.g. with a brush. Further information about the water tank is provided in these instructions for use (see Chapter 5 ‘Maintenance – Descaling the water tank’).
  • Traces of milk and coffee may stick to the top and bottom of the cup grille. If this happens, clean the cup grille.
