Jura manufactures a variety of coffee makers and appliances, including coffee grinders, frothers, accessories and espresso machines. The espresso maker’s Impressa E-line offers several features, including mild, regular or strong coffee settings, automatic grinding of up to 16 grams of coffee, an 8 oz. bean container and a separate funnel for ground coffee. Each machine they make is characterised by high quality, however, they are not without their problems.
If your Jura coffee machine is not working properly, you can visually inspect it, find the problem, and, if you can, fix it without having to call a service technician. Some malfunctions do not require special knowledge.
However, it is still worth reading the instruction manual. Repairing your Jura coffee machine will be easy if you understand the internal structure, where there is nothing complicated. However, in the case of the Jura Impressa coffee machine, which is quite expensive, you should not risk it without the ability to disassemble appliances.
In this article, we would like to introduce you to the most common problems you may face with a Jura coffee machine. Still, we would like to emphasise that proper use and care of the machine will greatly reduce the risk of breakdowns, so pay special attention to factors such as the quality of the water you put in your coffee machine, power supply surges, improper use of the device and wear and tear of spare parts.
The following measures will help to avoid many problems:
- Filtration and use of cold water only.
- Use only high-quality dry coffee beans.
- Make sure that no foreign objects fall into the device.
- Regular flushing of the system with specialised cleaning agents under the Jura brand.
- You cannot switch on the Jura coffee machine without ensuring that the water has been poured out.
- The filters should be cleaned regularly, preferably after 25 uses, even if the system does not require cleaning.

How do I clean my Jura coffee machine when it asks for cleaning?
Many of the problems with Jura coffee machines are caused by poor cleaning. For this reason, here we will show you how to perform the cleaning cycle of a Jura espresso machine.
The only thing you will need to clean your Jura espresso machine is the cleaning tablets; it is recommended to use only original cleaning products to clean your machine. Once you start the cleaning process, do not interrupt it, as this may cause damage to the machine.
We have selected two of the most popular models of Jura coffee machines (Jura S8 and Jura D6) to serve as a reference when cleaning your machine, and you can take them as a basis if you have a similar model as the procedure is almost always the same.
Automatic cleaning in Jura S8 or similar coffee machines, with digital display:
This machine with a large digital display will ask for a cleaning tablet every year, and it will tell you when it’s time to clean it (on almost all models with a digital display, it’s more or less the same).
Go to the menu on the digital display, usually by pressing the “P” button. From there, scroll through the options until you get to the cleaning menu and then go to the group cleaning menu, where you will also see an indicator of how long until the next cleaning is due; press there, and you will get the time it will take for the machine to clean (approximately 20 minutes, although it may be a little less), then press the start button.
After pressing the start button, the machine will ask you to empty the waste container; once you have done this and the drip tray is also empty, put the parts back in place. Next, place a jug to contain the water that comes out of the machine. Press “Next”, and the machine will start its cycle, passing some water through the pipes, before asking for the cleaning tablet.
Then the machine will ask you to add the cleaning tablet, which you should put into the bypass dispenser, every year a machine does not have a bypass dispenser, but they all have the chute for it, take the cleaning tablet and put it in there, close, press “Next” and the machine will do the rest.
Basically, you don’t need to be present while the machine does this process; there’s nothing else you have to do; it’s an automated process. What the machine does is clean the brewing unit with detergent, making sure to remove any oil residue, coffee residue or any other residue, to keep your machine clean and make great tasting coffee.
Automatic cleaning in D6 or similar coffee machines, without digital display:
D6 coffee makers are a bit different because they don’t have a digital display, so they only have an interface on the left with just text, but the cleaning process is very similar.
Again we will hold down the “P” button to enter the menu, and the cleaning option is in the “Rinse” part of this menu; after pressing there, the first option that appears is “M-Rinse”, which means milk rinse or milk cleaning, turn the knob skipping the options until you get to the cleaning click, by pressing the button on the “Clean” option, the machine will immediately ask you to empty the drip tray, so you have to remove it and make sure it is empty, do the same with the waste container.
When you have the container and drip tray empty, press the “Rinse” button (it is good to put a container under the coffee spout), and the cleaning cycle will start. First, it runs a little water, but then the machine will ask for a cleaning tablet, so you add the tablet, it is the same tablet used in all Jura machines, and you put it in the bypass dispenser.
The bypass dispenser on the D6 is right at the top; you simply put the tablet in there, press the “Rinse” button once more, and the machine will start the cleaning cycle, which can take at least 15 minutes. Everything is automatic; you don’t need to do anything else.
At the end of the cleaning cycle in any of the models, the machine will ask you to empty the waste container; when you remove it, you will see some water inside the drip tray, and inside the container itself, you have to remove it, empty it and put it back in its place. And that’s it! Your coffee maker is now completely clean and ready to use.
Descaling my Jura coffee machine:
The water tank of Jura coffee machines calcifies due to use; this calcification depends on the degree of hardness of the water. To ensure correct operation, the water tank must be descaled from time to time.
Softening products not recommended by Jura (such as vinegar) may contain substances that are harmful to your appliance or may leave residues. For this reason, we recommend using, if possible, Jura descaling tablets, which are specially made for use in these machines.
Here are the steps to follow to descale the tank of your coffee machine:
- Remove the water tank.
- If you are using a CLEARYL Smart filter cartridge, remove it as well.
- Dissolve 3 JURA descaling tablets in the filled water tank.
- Leave the descaling solution in the water tank for several hours (e.g. overnight).
- Empty the water tank and rinse it thoroughly.
- If you are using a CLEARYL Smart filter cartridge, reinsert it.
- Fill the water tank with fresh, cold water and reinsert it.
My Jura coffee machine froths too little milk
If, when frothing the milk, the machine does not foam sufficiently or the milk splashes out of the fine foam frother, this could be a problem caused by the frother not being cleaned.
So what you should do, is a thorough cleaning of the frother as follows:
- Remove the milk tube and rinse it thoroughly under running water.
- Carefully remove the professional fine foam frother from the Connector System with a gentle twisting motion.
- Disassemble the professional fine foam frother into its individual components.
- Rinse all parts thoroughly under running water. In case of stubborn milk residue, first, soak the components in a solution of cold water and a little dishwashing soap.
- Then rinse the removed components thoroughly.
- Reassemble the professional fine foam frother.
- Always check that all components are correctly and firmly assembled to work perfectly with the professional fine foam frother.
My Jura coffee machine is not brewing enough coffee
If you have a Jura coffee machine and during brewing, you notice that coffee only comes out drop by drop, this may be a problem because the coffee has been ground too finely and is clogging the system. In this situation, try adjusting the grind to a coarser grind on the grinder, as described below.
Please note that if you adjust the grind setting with the grinding mechanism stopped, damage to the rotary selector may occur. Therefore, we recommend that you adjust the grind setting only when the grinding mechanism is running.
- Place a cup under the coffee spout.
- Open the cover of the rotary selector for setting the consistency of the grind.
- Select the type of coffee preparation. For example, press the ‘Espresso’ button to start preparation.
- Turn the grinder adjustment knob to the desired setting (coarser than the one you have) while the grinder is operating. The preset amount of water flows into the cup. Preparation stops automatically.
- Close the cover of the rotary selector for setting the consistency of the grind.
If you have already adjusted the grind setting, but the problem persists, it is probably because the machine is calcified and therefore clogged; in this case, carry out a correct descaling, following the step-by-step instructions given in this article above.
No water comes out of my Jura coffee maker to make coffee
You have noticed that little or no water or steam comes out of the fine foam frother, and the pumping noise is hushed. If this happens, you should pay attention to the connection part of the fine foam frother because it may be clogged by milk residues or limescale particles that have come off during descaling.
By following these steps you will be able to solve this problem:
- Remove the fine foam frother.
- Unscrew the black connector using the hexagonal hole in the measuring spoon for ground coffee.
- Clean the connector thoroughly.
- Screw the connector back on by hand.
- Carefully tighten it with the hexagonal hole of the measuring spoon by no more than a quarter turn.
How to change the electric pump of my Jura coffee machine
The electric pump is an essential part of a well-functioning espresso machine. If it gets damaged or starts working with less pressure than it should, there will be no coffee, or at least not with the quality we expect from a real espresso.
So, if you’re having this problem, here’s how to change the electric pump, to fix it.
This procedure will take around 25 minutes.
- Spare pump
- Switch off and unplug the coffee machine.
- First, separate the parts of the machine that can remove manually.
- Loosen the screws at the back and also at the front.
- With the help of a flat-blade screwdriver, we remove the upper casing and remove the other casings.
- Be sure to loosen the pipe that is connected to the pump on one side.
- We can see that the pump is located at the bottom of the coffee machine. Now we gradually loosen each of the tubes and wires that connect it.
- We replace the pump with a new one and reconnect each of the tubes and cables we had removed (as you can see in the following video).
- Then we proceed to reassemble each of the parts that we had removed. While we put the rear casing back on, we must make sure to put the pump tube back on one side of the coffee machine; c can also put it on the other plate. Now we put on the upper casing and tighten all the screws on the upper rear part very well.
- Finally, we fit the remaining parts by hand.
If you still have any doubts about how to do this process, here is a video which, although it is not in English, is quite illustrative and will surely make everything clearer:
