Optimum Maintenance

Proper maintenance of an automatic coffee machine ensures better coffee quality and significantly extends the machine’s lifespan. For consistently excellent coffee and reliable machine performance, cleanliness and hygiene of the milk, coffee, and water systems are just as important as the machine’s technology itself. JURA has developed a complete range of phosphate-free maintenance products to make machine care simple and convenient at the touch of a button. The CLARIS water filter provides optimal water quality, while JURA cleaning tablets ensure that the brewing unit remains clean and free from coffee oils and residues. In addition, the milk system cleaning process keeps all milk lines hygienically clean and free from milk deposits.

If maintenance tasks are carried out correctly and regularly, the required time and effort are absolutely minimal. Maintaining a JURA automatic coffee machine is just as easy as preparing a coffee specialty: all it takes is the touch of a button. The combination of original phosphate-free JURA cleaning products and JURA’s automatic maintenance programs has been specifically designed to work together, ensuring impeccable cleanliness and consistently perfect coffee.

Always use original JURA maintenance products and follow the recommended maintenance intervals and instructions. Only original JURA maintenance products guarantee complete hygiene and optimal protection for your machine. JURA’s specially developed protection formulas are carefully designed to work perfectly with the maintenance programs and materials used in JURA automatic coffee machines.

The composition of water can vary greatly around the world, from region to region and even from day to day. Mineral content, including limescale levels, may be either high or low depending on local conditions. Harmful substances such as heavy metals, chlorine, and other contaminants can also be present in the water supply.The specially developed filter granules used in CLARIS water filters provide highly effective filtration, even in areas with low water hardness, and reduce harmful substances more efficiently than ever before. At the same time, valuable minerals and fluoride are retained, as they are important for human health and help coffee develop its full aroma.By optimally stabilizing the mineral content of the water and filtering out unwanted substances, CLARIS consistently delivers the ideal water quality for perfect coffee enjoyment.

Always. Since coffee consists of approximately 98% water, water quality plays a crucial role in the final taste. In addition to calcium, minerals, and fluoride, tap water in many regions may contain traces of lead, copper, aluminum, and chlorine. Both the quality and hardness of water can vary depending on the location and even the time of day.Thanks to their innovative filtration formula, CLARIS water filters are suitable for water supplies worldwide. They continuously provide fresh, perfectly filtered water by effectively reducing harmful substances such as lead and chlorine while preserving the essential minerals that help bring out the full aroma of the coffee.Superior water quality transforms every cup of coffee into a truly exceptional taste experience.

No, descaling is not necessary when a CLARIS water filter is used. The specially developed filter granules inside the cartridge absorb harmful substances and improve water quality, ensuring perfect coffee flavor. At the same time, beneficial minerals and fluoride are retained.The most important feature of CLARIS water filters is their ability to stabilize the calcium carbonate content of the water. This prevents limescale buildup, even when the steam function is used frequently, and actively protects the machine’s internal water system from blockages caused by scale deposits.

Mineral water is generally of high quality and provides the body with valuable minerals. However, due to its often very high calcium content and water hardness, which can reach up to 60°dH, it contains significantly more limescale-forming minerals than typical tap water.For this reason, mineral water is not recommended for use in automatic coffee machines, as it can promote limescale buildup and negatively affect the machine’s performance and longevity.

Yes. While calcium is considered the main enemy of coffee machines and other household appliances, other substances found in water, such as lead, copper, and aluminum, may also be harmful to health. Chlorine can negatively affect both the taste and aroma of coffee. However, certain minerals play an important role in allowing the coffee’s aroma to develop fully. These valuable minerals are preserved thanks to the specially developed filter granules used in CLARIS water filters. CLARIS filters reduce harmful substances while simultaneously improving water composition, ensuring the perfect taste in every cup of coffee.

The CLARIS water filter should be replaced either after 50 liters of water have passed through the machine or after 2 months of use, whichever comes first. Adhering to this replacement interval is essential to ensure the filter remains fully effective. Otherwise, optimal water quality cannot be guaranteed, which may also affect the perfect taste of your coffee.

Yes, because water hardness can still fluctuate even when a water softening system is installed. This is often due to variations in the softening process, the effectiveness of which may not always be known. In addition, many water softening systems do not remove substances that can affect the taste and aroma of water, such as chlorine. In these cases, the CLARIS water filter acts as an important regulator of water quality for your machine and is a key factor in achieving the perfect aroma in every coffee specialty.

The automatic coffee machine has not been programmed to operate with a water filter. As a result, the machine does not recognize that a water filter has been installed and therefore continues to request a descaling cycle. Make sure to activate, program, and rinse the filter according to the machine's instructions whenever a new filter is installed.

It is important to thoroughly clean the water tank every day and refill it with fresh water each morning. The water tank should also be cleaned carefully whenever the filter is replaced. To clean it, remove the tank, fill it with water before inserting the new filter, and dissolve 3 JURA descaling tablets in the water. Allow the tablets to dissolve completely, then rinse the tank thoroughly, insert the new filter, and program the machine accordingly.

To prevent the filter granules inside the CLARIS filter from drying out, the filter should always remain in water, meaning the base of the water tank must stay sufficiently covered with water. Ideally, store the water tank with the filter installed in the refrigerator. If space is limited, wrap the filter in aluminum foil or place it in a plastic bag and store it in the refrigerator. This will keep the filter active and ensure excellent aroma in your coffee specialties even after you return from vacation. Once you return, replace the water and thoroughly rinse both the water tank and the filter. We also recommend running hot water through the machine (approximately 1–2 servings, at least 200 ml in total) to flush the filter granules. If you are away for more than one month, replace the CLARIS water filter with a new one upon your return and rinse the machine before preparing your first coffee.

Yes. The materials used in CLARIS water filters are recycled wherever possible. However, they are not used to manufacture new CLARIS filters, as this is not permitted under food safety regulations. Used filters can be returned to the retailer or point of purchase for proper handling and recycling.

JURA automatic coffee machines feature integrated rinsing and cleaning programs that automatically notify the user when maintenance is required. Once the cleaning program is started, the machine prompts the user to insert the special JURA cleaning tablet. During the cleaning cycle, the water is heated to approximately 80°C. These high temperatures help eliminate bacteria while effectively removing coffee residues, oils, and fats from the brewing unit. If you prepare coffee specialties with milk or milk foam, the integrated milk system rinsing and cleaning programs, combined with original JURA maintenance products, ensure the highest standards of hygiene throughout the entire milk system.

One cleaning tablet is sufficient for each cleaning cycle. The formulation and size of JURA cleaning tablets are perfectly designed for a single cleaning program and ensure effective cleaning and optimal care of your machine.

The longer you postpone the cleaning process, the more coffee residues, oils, and fats will accumulate inside the machine. Over time, this buildup can noticeably reduce the quality, aroma, and taste of your coffee.

Fresh, cold milk is essential for preparing perfect coffee specialties with milk foam. We do not recommend simply placing the milk hose directly into a milk carton, as this does not provide sufficient protection against bacteria and germs. JURA milk containers ensure ideal storage conditions and the highest standards of hygiene. Whether you use the classic glass milk container, the insulated milk container, or the Cool Control milk cooler, which keeps milk at a constant 4°C, all JURA milk solutions help maintain optimal milk quality and deliver exceptionally smooth, light, and creamy milk foam.

With proper and regular cleaning of the milk system, the inside of the milk tube remains hygienically clean. However, over time, bacteria and germs can accumulate on the outside of the tube through contact with the air or handling by hand. If the milk tube is placed directly into a milk carton or bottle, these microorganisms may be transferred into the milk, making it impossible to guarantee optimal milk quality and hygiene. A closed milk system with a dedicated connector, into which the tube is securely attached, creates the ideal conditions for keeping milk fresh and hygienically protected.

Carefully selected materials, intelligent design, and the elegant appearance of JURA milk containers provide the ideal solution for milk storage. The specially designed connectors, which fit perfectly with the milk tube, have been developed exclusively for JURA coffee machines. Combined with optimal milk storage temperatures and intuitive maintenance and cleaning procedures, they ensure the highest standards of hygiene throughout the entire milk system.

The best way to prepare coffee specialties with delicious, light, and creamy milk foam is to keep the milk fresh and chilled at 4°C before use. All JURA milk containers are designed to maintain milk at the ideal temperature. Whether through active cooling with the Cool Control, thermal insulation with JURA insulated milk containers, or simple refrigerated storage using the glass milk container, JURA solutions provide optimal temperature conditions for milk and ensure perfect results every time.

The connectors (the fittings into which the milk tube is attached) create airtight connections between the milk container and the machine’s milk system. The milk tube can be connected and disconnected easily in just a few simple steps, ensuring consistently high standards of milk hygiene, whether you are preparing a coffee specialty with milk foam or carrying out the automatic milk system cleaning process afterward.

Many JURA automatic coffee machines allow you to enjoy coffee specialties with milk or milk foam, such as cappuccino, latte macchiato, flat white, and espresso macchiato, in exceptional quality at the touch of a button. To maintain this high level of quality, JURA has developed a dedicated milk system cleaning process. Together with the machine’s automatic cleaning program, the automatic milk system cleaning program effectively removes milk fats and proteins from the system. This keeps the milk lines clean, ensures proper hygiene, and guarantees consistently high-quality milk foam with every preparation.

For normal household use, we recommend replacing the milk tube every 3 months. If you prepare a large number of coffee specialties with milk foam each day, the milk tube should be replaced more frequently to ensure optimal hygiene and performance.
