What Jura cleaning tablets do and when to use them

Jura cleaning tablets are designed to dissolve in water and remove mineral buildup, coffee oils, and residue from the internal pipes and components of your Jura coffee machine. You use them during a cleaning cycle that your machine runs automatically—you do not manually scrub anything. Most Jura machines prompt you to run a cleaning cycle every 200 to 500 cups of coffee, depending on the model, though you can also start one manually whenever you notice slower water flow or weaker espresso shots.

The tablets work best when your machine's water tank is empty and the drip tray is in place. A single tablet is usually enough for one cleaning cycle, though some larger machines or heavily used commercial models may need two. The entire process takes about 20 to 30 minutes and produces hot water and cleaning solution that flows through all the internal pathways where coffee residue collects.

Key Takeaways

  • Drop one Jura cleaning tablet into the water tank when your machine prompts you or when you notice slower flow, then start the cleaning cycle from the menu.
  • The machine heats the tablet and water together, then automatically pumps the solution through the group head, pipes, and dispensers to break down buildup.
  • After the cleaning cycle finishes, you must run two to three water-only rinse cycles to flush out all tablet residue before making coffee again.
  • Use one tablet per cleaning cycle; do not drop multiple tablets in at once or use a tablet that has already been dissolved.
  • Store tablets in a cool, dry place and check the expiration date on the package, as old tablets may not dissolve properly.

Step-by-step: Running a cleaning cycle with a tablet

Start by emptying the water tank completely. If there is still water in the tank, the tablet will dissolve too quickly and unevenly, and the cleaning solution will be too diluted to work well. Remove the tank, pour out any remaining water, and dry the inside with a clean cloth if you have time.

Drop one tablet into the empty tank. Do not break it into pieces or try to dissolve it beforehand—the machine needs the tablet to dissolve gradually as the cycle runs. Replace the tank in the machine and make sure it is seated firmly.

Open the machine's menu on the display screen. On most Jura models, you will find a "Maintenance," "Service," or "Cleaning" option. Select it, then look for "Cleaning Cycle" or "Rinse Cycle." The exact wording varies by model—check your manual if you cannot find it. Press start and the machine will begin heating water and dissolving the tablet.

The cycle will pump hot cleaning solution through the group head (where the portafilter or coffee grounds go), the internal pipes, and the milk frother if your machine has one. You will see water and foam come out of the group head into the drip tray. This is normal. Do not interrupt the cycle or open the machine while it is running. The whole process takes 15 to 25 minutes depending on your model.

Rinsing after the cleaning cycle is complete

When the cleaning cycle finishes, the machine will display a message telling you to rinse. Empty the drip tray and refill the water tank with fresh, cold water. Do not add another tablet—this step uses water only.

Run the rinse cycle from the same menu where you started the cleaning cycle. The machine will pump plain water through all the same pathways to wash away the tablet residue. This first rinse usually takes 5 to 10 minutes. When it finishes, empty the drip tray again.

Refill the water tank a second time and run the rinse cycle again. Most machines require at least two rinses, but some models ask for three. Follow the prompts on your machine's screen—it will tell you when rinsing is complete and the machine is ready to brew. If you skip this step or do not rinse enough times, your next cup of coffee will taste soapy or bitter.

Common mistakes that reduce cleaning power

The most frequent error is adding a tablet to a tank that still has water in it. The tablet dissolves too fast and the solution becomes too weak to clean effectively. Always empty the tank first, even if it means pouring out water you could have used.

Another mistake is interrupting the cycle or opening the machine while it is running. The pressure and temperature need to stay consistent for the solution to reach all the internal passages. If you open the group head or remove the tank mid-cycle, the machine may stop or the cleaning will be incomplete.

Using an old or expired tablet is also common. Jura tablets have a shelf life printed on the package. If a tablet is more than two years old or has been stored in a humid place, it may not dissolve properly or may clump inside the tank. Check the date before you use it.

Finally, skipping the rinse cycles or rinsing only once will leave soap residue in the machine. This affects the taste of your coffee and can build up over time. Always complete all the rinse cycles your machine asks for, even if it seems like extra work.

How often to clean and what to do between cycles

Most Jura machines display a cleaning reminder after a set number of cups—typically 200 to 500 depending on the model. You can see how many cups your machine has counted by checking the menu. When the reminder appears, run a cleaning cycle within the next few days. You do not have to stop when ready, but waiting more than a week after the reminder usually means more buildup has accumulated.

Between cleaning cycles, rinse the group head and portafilter with hot water after each use. This removes loose coffee grounds and prevents them from drying inside the machine. If your machine has a milk frother, purge it with steam and wipe the nozzle with a damp cloth right after you use it. These small steps reduce how much buildup forms and make the cleaning tablets more effective when you do run a cycle.

If you use your machine very heavily—more than 10 cups a day—you may want to run a cleaning cycle more often than the machine suggests, even if the reminder has not appeared. Buildup happens faster with heavy use, and cleaning more frequently keeps the machine running smoothly and the coffee tasting fresh.

Troubleshooting: What to do if the cycle does not start or finish

If you press start and nothing happens, the machine may be in a locked state or the tank may not be seated properly. Remove the tank, check that the contacts are clean and dry, and push it back in firmly until you hear or feel a click. Then try the cycle again.

If the cycle starts but stops partway through, the machine may have detected a problem—usually a clog in the group head or pipes. Turn off the machine, wait five minutes, and try again. If it stops again at the same point, the clog is serious enough that a single cleaning cycle will not clear it. Run the cycle a second time, and if the problem persists, contact Jura support or a service center. Do not try to force water through by hand or use tools to clear the pipes, as you may damage internal seals.

If water comes out very slowly during the cycle, the tablet may not have dissolved completely. This usually happens if the tank had water in it when you added the tablet. Let the cycle finish anyway—it will still help—but plan to run another cleaning cycle in a few days to finish the job.

Storage and safety information

Store Jura cleaning tablets in their original container in a cool, dry place away from direct sunlight. A kitchen cabinet or pantry shelf works well. Do not store them in the refrigerator or freezer, as moisture can cause them to clump or lose strength. Keep them away from children and pets—the tablets are not meant to be eaten and can cause stomach upset if swallowed.

If a tablet spills into the water tank and you are not ready to run a cleaning cycle, you can remove it with a spoon or small net. Rinse the tank thoroughly with water before adding fresh water for regular use. If tablet powder gets on your skin, rinse it off with water. If it gets in your eyes, rinse with water for several minutes and seek medical attention if irritation continues.

Never mix Jura tablets with other cleaning products or use a different brand of tablet in a Jura machine. Different products have different formulas and may damage internal seals or leave residue that affects taste. Stick with Jura brand tablets designed for your specific machine model.

Frequently Asked Questions

Can I use a Jura cleaning tablet in a different brand of coffee machine?

No. Jura tablets are formulated for Jura machines and their specific internal design. Other brands use different materials and seals that may react badly to Jura's formula. Use the cleaning tablets made by your machine's manufacturer instead.

What if I accidentally used two tablets in one cycle?

The cycle will still run, but the solution will be too strong and may leave more residue that requires extra rinsing. Complete all the rinse cycles your machine asks for, then run one or two additional water-only rinses to be safe. In the future, use only one tablet per cycle.

Do I need to clean my machine if I do not use it for a week?

No, but you should run a cleaning cycle as soon as you start using it again if the machine has not been used in more than two weeks. Stagnant water can develop mineral deposits and mold, and a cleaning cycle will flush these out before you brew coffee.

Can I buy Jura cleaning tablets online or only at a store?

Both. Jura tablets are sold through the manufacturer's website, Amazon, specialty coffee equipment retailers, and some grocery stores. Check the expiration date on the package before you buy, especially if ordering online. Buying directly from Jura or an authorized retailer ensures you get a fresh product.

What is the white powder left in the tank after the cleaning cycle?

That is undissolved tablet residue. It means the tablet did not fully dissolve, usually because there was water in the tank when you added it. Empty the tank, rinse it thoroughly, and refill it with fresh water before running the rinse cycles. The residue will not harm the machine, but it can affect taste if you do not rinse it out.
