- Place a container under the coffee spout.

Descaling Program
If you are not using a CLARIS filter, the machine will eventually prompt you to descale. Use Jura descaling tablets and follow the instructions.

Filter Replacement
If using a CLARIS filter, replace it when prompted by the machine (approximately every 2 months or after 50 liters of water). This prevents limescale buildup and ensures water quality.
