2. Filling the Water Tank
Remove the water tank from the machine. Fill it with fresh, cold tap water up to the 'MAX' mark. Insert the water filter (if using) as per the filter instructions, then reinsert the tank firmly into the machine.

4. First Use and Rinsing
Plug the machine into a power outlet. Follow the on-screen prompts or indicator lights for the initial rinsing process. This cleans the internal system and prepares the machine for brewing.
Operating
1. Brewing Coffee
Place a cup under the coffee spout. Select your desired coffee specialty (e.g., Espresso, Coffee) using the rotary switch or dedicated buttons. The machine will automatically grind the beans and brew your coffee.

3. Using Pre-ground Coffee (if applicable)
Some models allow for pre-ground coffee. Open the funnel for pre-ground coffee, add one level measuring spoon of pre-ground coffee, and then select the pre-ground coffee function before brewing.
Maintenance
Regular maintenance ensures the longevity and optimal performance of your Jura D4 coffee machine.
1. Emptying the Drip Tray and Coffee Grounds Container
