Preventing damage To avoid damage to the machine and the mains cable: U Do not use the J8 and the mains cable near hot surfaces. U Do not allow the mains cable to rub against sharp edges and ensure that it does not become
trapped. U Never allow the mains cable to loosely hang down. The mains cable could pose a tripping hazard or
become damaged. U Protect the J8 from weather and direct sunlight. U Only connect the J8 to a mains voltage corresponding to that stated on the rating plate. The rating
plate is located on the underside. U Connect the J8 directly to a domestic power socket. Using multi-socket adapters or extension cords
may cause overheating. U Do not use alkaline or alcohol-based cleaning agents; only use mild cleaning agents and a soft cloth. U Do not use any coffee beans treated with additives or caramelised coffee beans. U Only fill the water tank with fresh, cold, non-carbonated water. U Switch the machine off with the On/Off button Q if you are going to be absent for a longer period of
time and remove the mains plug from the power socket. U Only use original JURA maintenance products. Use of products that are not explicitly recommended
by JURA could damage your J8.
Danger of electric shock Water conducts electricity. Do not bring water and electricity into contact with one another: U Never touch the mains plug with wet hands. U Do not immerse the J8 and/or mains cable in water. U Do not put the J8 or any individual parts in the dishwasher. U Before cleaning, switch the J8 off with the On/Off button Q. Always wipe the J8 with a damp cloth
rather than a wet one, and protect it from prolonged exposure to water splash. The J8 must not be cleaned with a jet of water. U The J8 is not suitable for installation on a surface where a jet of water can be used.
Danger of burns, scalding and injury U Do not touch the spouts during operation. Use the handles provided. U Optionally, your J8 can be remotely operated using mobile devices. When preparing a product or
initiating a maintenance programme, make sure that other people are not put at risk ­ for example, through contact with the spouts. U Be careful to ensure that the fine foam frother is correctly installed and clean, otherwise the fine foam frother (or parts of it) may come loose.

9 Troubleshooting

Problem Insufficient foam is produced when the milk is frothed or milk sprays out of the fine foam frother.
The Coffee Eye’ reports a cup under the coffee spout even though no cup has been placed there. Coffee only comes out in drips when it is being prepared. There is dry ground coffee behind the coffee grounds container. Fill water tank’ is not displayed although the water tank is empty. Grinder is making a very loud noise.

Cause/Result The fine foam frother is dirty.
The cup detection sensor behind the coffee spout is dirty.

Action T Clean the fine foam frother (see chapter 7 Maintenance ­ Cleaning the milk system’). T Dismantle and rinse the fine foam frother (see chapter 7 Maintenance ­ Dismantling and rinsing the professional fine foam frother’). T Clean the sensor with a damp cloth.

The coffee is ground too finely and obstructs the system. The water hardness may not have been correctly set. The beans used are resulting in an above- average volume of ground coffee.
There is a lot of limescale in the water tank.
There are foreign objects in the grinder.

T Put the grinder on a coarser setting or use coarser ground coffee. T Perform descaling (see chapter 7 Maintenance ­ Descaling the machine’).
