Connecting milk

Your W8 creates fine, creamy, feather-light milk foam with a perfect consistency. The most important requirement for frothing milk is a milk temperature of 39–46°F (4–8°C). We would therefore recommend using a milk cooler or a milk container.

Remove the protective cover from the fine foam frother.
Connect the milk pipe to the fine foam frother.

information The milk system of your W8 has a connector HP3 and an interchangeable milk spout CX3.

Connect the other end of the milk pipe to a milk container or a milk cooler.

Preparation

Hot coffee, hot steam and hot water can cause scalding. Scalding is a serious burn.

Use extreme care when handling hot liquid or steam.
Allow liquid to cool down before drinking.
In the event of scalding, rinse affected area with cold water and seek medical attention.
Keep children AWAY.

Coffee tastes best served hot. A cold porcelain cup cools the beverage – and impairs the taste. We therefore recommend prewarming the cups. You can purchase a JURA cup warmer from your specialized dealer.

Preparation with preselection

Press the button to open the Specialty Selection.
Now choose the desired preselection for the product:

Specialty Selection	Meaning
– 'Extra Shot' (for latte macchiato, cappuccino and flat white)	The product is prepared with two brewing operations, with half the amount of water – for a specialty coffee with a particularly intense taste.
– Ground coffee (all specialty coffees)	The product is prepared with ground coffee.

Latte macchiato/cappuccino and other specialty coffees with milk

Your W8 prepares the following specialty coffees with milk at the touch of a button:

Cappuccino
Latte macchiato
Cortado
Macchiato
Flat white

Example: Latte macchiato
Precondition: Milk is connected to the fine foam frother.

Place a glass under the fine foam frother.
Press 'Latte macchiato' (on page ).
The preset amount of milk foam flows into the glass.

information There is a short interval while the hot milk separates from the milk foam. This allows the typical layers of a latte macchiato to form.

The preset amount of water for espresso flows into the glass.

To ensure that the fine foam frother always works properly, you must clean it daily when you have been preparing milk (see chapter 'Maintenance – Cleaning the milk system').

Espresso and coffee

Example: Coffee

Place a cup under the coffee spout.
Press 'Coffee' (on page ).
The preset amount of water for coffee flows into the cup.

Americano and lungo

For the americano and lungo, the W8 blends the coffee with hot water using a special preparation method. This results in a full-bodied specialty coffee which is particularly easy to digest. You can change the amount of this additional water (see chapter 'Preparation – Adjusting the product settings').

Ground coffee

You can choose to use a second coffee variety, for example decaffeinated coffee, with the filter funnel for ground coffee.

Basic information about ground coffee:

Never add more than two level measuring spoons of ground coffee.
Use ground coffee which is not ground too finely. Very fine coffee can block up the system so that the coffee only comes out in drips.
If you did not fill the machine with a sufficient amount of ground coffee, 'Not enough ground coffee' is displayed and the W8 stops the operation.
The desired specialty coffee must be prepared within approximately one minute after filling with the ground coffee. Otherwise the W8 stops the operation and is once more ready for use.
All specialty coffees with ground coffee are always prepared following the same model.

Example: Espresso with ground coffee

Place an espresso cup under the coffee spout.
Press the button to open the Specialty Selection.
Press 'Ground coffee' .

Troubleshooting

Problem	Cause/Result	Action
Insufficient foam is produced when the milk is frothed or milk sprays out of the fine foam frother	The fine foam frother is dirty.	Clean the fine foam frother (see chapter 'Maintenance – Cleaning the milk system'). Dismantle and rinse the fine foam frother(see chapter 'Maintenance – Dismantling and rinsing the fine foam frother').
Coffee only comes out in drips when it is being prepared	The coffee is ground too finely and obstructs the system.	Set the grinder to a coarser setting (see chapter 'Preparation – Adjusting the grinder').
	The water hardness may not have been correctly set.	Perform descaling (see chapter 'Maintenance – Descaling the machine').
There is dry ground coffee behind the coffee grounds container	The beans used are resulting in an above-average volume of ground coffee.	Reduce the coffee strength or choose a finer grinder setting (see chapter 'Preparation – Adjusting the product settings').
Little or no water or steam comes out of the fine foam frother. The pump is very quiet.	The connector of the fine foam frother may be blocked by milk residues or limescale fragments loosened during descaling.	Remove the fine foam frother. Unscrew the black connector with the aid of the hexagonal hole on the measuring spoon for ground coffee. Clean the connector thoroughly. Screw the connector back on tightly by hand.
Grinder is making a very loud noise	There are foreign objects in the grinder.	Contact customer support in your country (see chapter 'JURA contact details').
