How to Open and Disassemble Jura Impressa S9 Coffee Machine 

+Dezmo101 Glad we could be of help!

+Jay Brady Hi, the loud sound could be the pump or the brew group solenoid valve. Please make the ground coffee is not too fine. It should be fine like table salt grain. Please adjust the fineness and retry

Error 8 is permanently by replacing the brew group piston o-rings and seals in the drainage valve. You will need to remove the brew group from the machine, take it apart and replace the seals to fix Error 8. It is a common problem in all Jura espresso machines.

Parts Guru Thanks - do you have a video about taking apart the brew group?? It's sounding pretty complicated, but I'm sure you're right about the problem, since more superficial fixes are not working.

+Judy Harmon Hi Judy: we have almost all the parts available for S9. I suggest you order the oval head tool to open the machine. Inspect couple of parts such as multiway valve, PTFE tube connection to isolate the issue. Also, you want to check the solenoid valve while you have the machine opened.

+James Macauley Hi James, the machine's water passages are blocked with calcium sediments. Please stop using Clearyl water filters. They're expensive and more importantly ineffective and doesn't function as advertised. Jura recommends using the filter without the need to descale the machine. That's an effort to sell and promote Clearyl filters. Despite using the filter, these machines need to be descaled regularly every six months. Failure to do so leads to the accumulation of calcium deposits inside the water passages overtime and blocks the water flow. If you're able to get hot water through the water outlet then I recommend you descale the machine thoroughly. You can use Jura Descaling tablets, if you have them, or purchase our descaler. While you have the machine opened, please operate the machine and monitor the water flow from pump to boiler and so forth. See if you can find the blockage where water stops flowing. Please check the steam solenoid valve, membrane regulator, dispensing valve, and water pump. The filter removes other minerals from water but fails to remove calcium sediments. Jura primarily is a marketing company that gets these machines manufactured by Swiss company that also makes coffee machines for Siemens, AEG and other popular European brands. They're not technically familiar with the internal schematics and parts of these machines. They have outsourced a repair business in the US to a third party that repairs home appliances for Delonghi. This is a primary reason their US office won't sell parts to customers. The above is just to give you a brief background about Jura users. Hope it helps you make educated decision when looking to purchase coffee machines in future.

Hello Evan, The brew group water inlet is clogged or blocked. If the water in the drip tray is warm then you'll need to check the water inlet on the drainage valve. Replace the drainage valve or the brew group seals and thoroughly clean out the brew group by disassembling it. We have a video posted on our channel that demonstrates how to rebuild the brew group. Also, check the magnetic valve metal needle that push opens the spring loaded valve with white actuator for allowing hot water into the brew group. If the metal pin is not aligned with the spring loaded actuator then hot water is also directed to the drip tray. Hope the above helps!

+Joel Salter Yes, we are in Lansdale, PA

Hi Andrew. Please give us a call and we will be more than willing to remedy the issue.

I just sent the above message to partsguru by mail as well and instantly got a message back. Their service is amazing... Here is PartsGuru's response: Buying a used or broken machine inherits its own past life secrets. The secret being you do not know details on the maintenance of the machine.Your efforts to revive appear to be very proper and made some functions re-start.Almost all Jura machines suffer from the use of expensive & ineffective Filter cartridges which do not prevent accumulation of Calcium deposits in the hydraulic system. Please know this and at some stage you have to manually descale the machine for aggressive & comprehensive descaling. Manually descaling instructions are on our website.The fill beans error means the beans are not fed into the grinder because the setting is too fine or the burrs are worn out and not grinding within time limit of 17 seconds. You may have to check & fix these. Very fine powdery grind does not make strong coffee. For adjustment of grind fineness, do not rely on the position of the knob. Feel the used coffee between the thumb & finger. It should not be finer than table salt Grain.To bypass the fill beans error, try pre-ground coffee and use slightly coarser coffee powder than table salt and see if brew group completes the cycle & makes espresso. This will localize the problem to the grinder. The grinder definitely needs good cleaning and possibly replacing the grinding burrs.Conclusion:1- Manually descale the machine to clean the system and2- Fix the grinderLet me know the results.Sincerely Edward - Technician Parts Guru

Also - it only trips the circuit breaker once (usually - occasionally it happens twice). I wait about 30 seconds, push the reset button on the GFCI, turn the machine back on, and that's it. It works fine the rest of the day.

+R Scheibner Hello: there is couple of electrical components that you can inspect. Check the thermal fuse (blue wire with fuse) mounted onto the steam boiler. The other part to check is the transformer. It's located beside the pump on the inside. Please operate the machine with the rear panel removed. Ensure there's no water leaking from the steam solenoid valve or any other part on the transformer. Please operate it carefully. If you're not comfortable, you may send the machine to us for repairs.

Hi J Smith, is this a manual steam wand or the professional frother that draws milk from the milk container?

Hi Thank you for taking time out to reply. Its these parts I need? Regards twitter.com/Bumpydog3/status/869300715952508928

+vkturbo176hp Hello, Please clean the milk frother thoroughly. You can use the Jura cappuccino cleaner or RINZA to flush out any dried milk deposits that could be blocking the air intake into the frother.

Please email or call us to talk to Edward. He'll suggest the best option.

Thanks! I will call next week. What is the best time & number to call. Regards, -russ

+Parts Guru , Wanted to update you on the issue with my unit. The more I thought about it, knowing that everything was actually working, but just taking a lot longer to produce the cup of coffee, and the pump being a lot louder, I wanted to look to see if something was hindering the water from getting into the machine. Although I have only used purified RO water, and did the clean cycles, keeping the water tank clean, I removed the tank and looked closely at the place where the water flows from the tank into the machine. I saw a few tiny debris, so took my vacuum to such the dirt from the small screen. Well, the dirt did not move. I took a small plastic tool and when I tried to scrape the debris, it was stuck and gunky on the screen. I then proceeded to scrape it all together and using the vacuum, was able to get it off the screen. I then took hydrogen peroxide and put a little on the screen to help clean it. I waited a few minutes and them vacuumed it again. Lastly, I took my compressor and blew forced air onto the screen to make sure it was completely free of obstruction. I then put the water tank back on and ran a cup of coffee. WOW! The pump was very quiet and the coffee flowed nicely. No where in the maintenance instructions does it say to clean the screen. I do not know how to remove it, or would have done it differently. Also, the technician at Jura never mentioned that it could have been the reason. He just wanted me to send in the unit and charge me $265 to repair it. So, please make note of this very simple preventative maintenance step that can greatly improve the performance and help it run much longer w/o problems. If you have the procedure to remove the screen at the water intake, please let me know. Thanks! Final note, my wife said that she would recommend white vinegar to clean with instead of the peroxide, so that is what I will use from now on.

+valerie Squire if you instert the new filter and then press the center button on the rotary dial, it should run through the sequence and reset the message. i think it only works with the blue filter

+Dennis Dowhy Hi Dennis: Typically when there's an issue with temperature sensor, it displays error code such as Error 4. The other reason for HEATING could be due to lack of Descaling the machine. When was the last time you descaled it? What Descaling product did you use? The calcium sediments in water accumulates at the fittings, connections and inside the boiler. As a result, the boiler fails to reach the desired temperature and thus displays HEATING. Please try to descale the machine first. Run multiple cycles using the authentic descaler to ensure its thoroughly descaled.

wow, now thats a fast response :) we use the authentic 'Jura Decalcifying/Descaling Tablets' for descaling but this doesn't solve the issue. like i said this has been going on for years, I bought the machine back in 2013 and it only worked properly for a few months I think, so basically for almost 3.5 years now we've been playing this game of racing to make our cups of coffee before it gets stuck in HEATING mode. this happens 100% of the time, regardless of how many times we have cleaned and descaled the machine. it would be nice to finally figure out how to fix this one for for all. it's especially troublesome when we have guests over and then we get stuck in this mode and can't make coffee for them. I have never seen an error code shown on the display. It'll just get stuck on 'HEATING' and stay that way until you turn the machine off, and even then if you turn it baack on too soon it'll just go right to HEATING and still not let you make coffee.

+Dennis Dowhy You can try to replace the temperature sensors on each boiler. XS90 has two boilers/thermoblocks each uses a different sensor. The other issue could be with thermal fuse that's also clamped onto the boiler. But, at this point, it's hard to tell whether it's a sensor or fuse.

Hi Marios: Sounds like there are broken components that are preventing you from removing the drip tray. Are you able to partially open the tray? You can remove the top cover to see what's causing the blockage in the brew group area. Let us know what you find.

Hi, it sure is repairable. Is the ground coffee wet or dry? You can either fix it yourself or ship your S8 to us for repairs.

+Ian Brock What was the original malfunction with the grinder? What exactly did you fix? Did you remove the grinder burrs?

+Ian Brock Please check if motor is getting power. The converter AC to DC may be not working (power board problem).

Hi, many thanks for the swift reply. It gave the beans empty light though it was half ful,l it stopped mid grind, so I took the grinder apart and pulled the burrs out. I then cleaned out the chamber and coffee port into the brew unit and re assembled. Test ran with and without beans and the motor still didn't run. How would I test for power at the motor? I have a multi meter, but is it a 12v motor or is it mains voltage?

***** What model is your Jura machine? Sometimes replacing the drip tray helps as the metal contacts get worn out over time and fails to fully engage with the metal sensors located at the back of the machine.

Parts Guru it is the S9 - same machine as in your video. Thank you for your feedback and direction.

Hello Marina, There is a solenoid valve in S9 that controls the flow of steam to the front steam wand. The solenoid valve is probably leaking. I suggest you order the oval head tool, to remove the rear panel and inspect the solenoid valve. You can also check other leaking components inside the machine while you have it open. You can order the oval head tool by clicking the link below: www.shopjuraparts.com/products/jura-oval-head-tool

How much is the tool? I think it's worth checking out. Do you? And FYI, the machine is almost 12 years old, not 10, I didn't realize just how long we've owned it.

Hi Seema, You sure can send your machine in for repairs. Our customer service staff will email you the shipping instructions.

The electronic board could be faulty. We have seen numerous cases where S9 model gets stuck in cleaning mode. Unfortunately, the power board is quite expensive. Would you be willing to trade in your machine for another one touch cappuccino machine?

+Kyla Farmer Hi Kyla: your S9 needs thorough descaling. Descaling removes the calcium sediments from water passages inside the fluid system. The calcium sediments accumulated over time and restricts the water flow. That in turn displays FILL SYSTEM error. When was the last time you descaled your machine? How long have you owned it?

My Jura S9 is doing this. Did you ever find a fix for it?

Hello Ali, the XS9 model has a muliway valve that controls the steam and hot water flow. Also, the steam boiler could be partially clogged with calcium sediments. Please check both items.

+Parts Guru Thank you very much for the fast reply! I opened the machine and realized that the steam boiler was leaking from both inlet and outlet parts! I ordered few O-rings and will change it and see if that will fix it. Thanks again.

+Deone120 Hi, this part is not available. What's the malfunction with your machine?

Hi, are you able to remove the used coffee grounds container?

+Parts Guru No I cannot remove the tray or used coffee grounds container. Otherwise it seems fine. Removed the top cover, but that doesn't seem to be helping me any.

+Parts Guru Okay, I got the tray out. Removed the trim tray in front and nearly had to force it. Now I'm getting an empty grounds empty tray message even though it's been emptied.

+Brad Willis Nevermind, fixed it. Had to clean and dry the metal strips at the rear of the tray. The moisture was fooling it into thinking that the tray was full.

+Anthony Murray - Hello, Anthony - When you replace the brew group, ensure the big white gear is at three to four notches down from the top of cylinder, and the coffee compacting cup is all the way down. That is considered a home position. When you start the machine, the encoder will reset the brew group itself. You should not experience any issues as long as the brew group is in home position.

+Parts Guru Thank you. I was afraid that since the encoder is now out of synchronization with the brew group due to the broken drive gear that it might not be able to be re-synchronized. How does the encoder find synchronization again? Just curious...

Hi Brad, what version of S9 do you have? Can you let me know the 5 digit article number printed on the white sticker inside the front control panel?

Part 13215. I did get it to stay for now. Drilled the hole slightly larger and used a bolt and washer. Not ideal but working for now. If there's an easy way to release the pour spout housing for future reference, let me know. Thanks in advance!

You will need to open the front door. Detach the coffee inlet tube from the brew group so the door can be opened easily. Then, you’ll need to remove the coffee spout by pressing the two tabs placed on the inside of the door to dismantle the spout.

Hello: a little bit of water (tea spoonful) is normal as the residual water from brewing coffee is drained. How much water do you notice in the pan?

Parts Guru thanks for the super quick reply it probably a couple of teaspoons nothing extreme. So when should I be worried about fixing it?

Hi Mark, there is a sensor mounted on the boiler that generates steam. The sensor gets corroded and does not measure the correct temperate. As a result, it shows the error you're seeing or display Error 4. You can replace the sensor yourself and have it replaced by an experienced technician. We have the sensor in stock.

+Parts Guru Thank you for the prompt reply, i've not done any replacement before. How much would the sensor cost? and if i were to employ your service, what would be the cost as well?

Replacing the sensor is not difficult but it depends on how mechanically inclined you are and your experience repairing the home appliances. The Video shows how to remove the rear panel using the oval head tool. Are you located in the US?

Hi Suzanne, the oval head tool is custom made in the U.S. to specifically remove the oval head screws without physically damaging them. You can order it from our Online Store.

Parts Guru Thank you very much

Did you ever find a fix for this? I am experiencing the same thing on my Jura S9.

Hello, The oval head tool is listed for purchase on our website www.shop.partsguru.com. Part number is 0010635.

@dhole177 ... Ditto that near Denver .... we're Vail, Colorado

+Rich Snyder Hello Rich: The frother needs cleaning (not just rinsing under water tap). The connections from milk container to the frother must be air tight. If any air is sucked then the milk will not pull from the bottle. The warm air or water is coming out because the milk is not pulled from the milk container. If you are using a Jura milk carafe, then disconnect that from the frother silicone tube. Take milk in a pitcher and dip the silicone tube in it. Let me know if that helps.

Thanks for your help, I found that above the frother nozzle, was clogged, it appeared that over time the mile had sucked up and into the fixed part above the removable milk frother and clogged over time, I used a paper clip to open and cleaned it well, working very well now.

+Rich Snyder Glad to hear that it works! Enjoy the latte's and cappuccino's.

Oscar Hernandez Hi Oscar, Please be as descriptive as possible. What happens when you press the coffee button? Does the grinder engage and grind the beans? Do you hear the brew group moving? Is there hot water in the drip tray? Does your machine go through the complete brewing cycle and still does not produce coffee from the front spouts?

Parts Guru Thank you for your prompt response. Then he explained what it does exactly my coffee machine. When I press the coffee button, starts working the grinder (grinding coffee without any problem), the group heard moving, the display screen shows all correctly, but the group does not come out coffee and the drip tray is completely dry . But the waste tray, throws dry and ground coffee. I hope this description helps you understand my problem, thank you Guru.

Is the ground coffee completely dry? If so, the hot water is not getting into the brew group. Can you please operate the machine with completely empty and dry drip tray? Press the coffee button to make coffee; Is the water in the drip tray hot or cold? If the water is hot, then either the brew group drainage valve or magnet valve are not working.

Ian Seed Yes, the brew group needs to be refurbished that requires replacing piston gaskets and drainage valve o-rings.

Hi Michael, It's probably due to an internal leakage or lack of descaling. When was the last time you descaled your machine? What is the name of product you used for descaling? Do you see any visible leakages outside of the machine or on the countertop?

Parts Guru hey guru, I am also having this issue. I descaled this morning. What would you do about an internal leak? Could this he a bad water sensor? Any help is appreciated thanks!

Hi Max: Please run multiple descaling cycles to ensure there's no blockage inside the hydraulic system. Calcium sediments build up overtime and starts to blocks water flow that results in Fill System error. If further descaling does not help, I suggest you open the machine to find any visible leaks.

We tried descaling again to no avail. The issue only happens if it has run out. If we don't let it run out it works fine however if it does then we have to wait for about a day to use again.

Do you see water leaking anywhere inside/outside the machine?

In S9 models, the angled silicone hose that connects flow meter to hot water pump often leaks. The flow meter is located to left rear of the machine. If you have the rear panel removed, please check the flow meter and pump connection.

Parts Guru Do I run the machine with the back open to check if the angled silicone hose is the problem? If so, can I purchase it thru you? Also, I need the oval head bit. Can I get that thru you as well? Thank you!!!

Here's the link to purchase oval head tool: shop.partsguru.com/Jura-Oval-Head-Key-Stainless-Steel-0010635.htm . Operate the machine with rear panel removed to isolate the source of leak.

Parts Guru Hi Guru. I opened the back up and you were right. The leak is from the diaphram regulator hose and the junction of the 3 way connector which is connected to the relief valve. But the leak is where the hose goes into the 3way connector. What do I need to do?

Marie S Chio Please email the picture of the leaking part. We have all parts (hose, regulator, relief valve) in stock. The picture will help us identify the leaking part. We will let you know the part you need to replace so you can fix your machine and get back to enjoying coffee!

+Eric Novikoff Hello, It appears to be the issue with the electronic module. What model Jura machine do you have and how long have you had it?

It's the z7, I've had it about 3 years.

+chessecake Morris Either replace the drip tray or replace the metal contacts on it. We have both items available.

+Parts Guru do u know how many contacts the machine should have for the sensors as ours only has 3 and wondered has one snapped off

I thought the same thing when trying to troubleshoot a problem. Ours has three contacts as well; two on the left and one on the right. If you look carefully at this video, the PartsGuru machine is the same.

We had this message recently. Our problem was that there was a compressed wafer of ground stuck to the back, stopping the tray from being inserted all the way. This made the problem even worse, as the counter for removing the tray when the ground tray was full kept getting reset, meaning even more grounds overflowed into the main tray. A good clean out made the whole tray fit snugly again and fixed the problem.

I have a s9 Impressa one touch started making a very small quantity of coffee and lots of water dripping in the pan then got stuck on empty tray any idea of what the problem could be? Thank you

Hi: There could be more than one item that would need to be inspected? Are you willing to fix the machine yourself?

Please email us with detailed issue to sales@partsguru.com

+Parts Guru I emailed you, but still no response.

Hi Russ, please describe your issue so I can assist.

+Parts Guru I have done this twice now, both as a reply (1 month ago) and as an email you asked me to send. I was giving you an update regarding the issue I was having. Please read and respond to my questions. Here it is again: Wanted to update you on the issue with my unit. The more I thought about it, knowing that everything was actually working, but just taking a lot longer to produce the cup of coffee, and the pump being a lot louder, I wanted to look to see if something was hindering the water from getting into the machine.

That's good to hear you were able to fix your machine. I don't know how to remove the screen but will explore it and document the steps so it can be shared with others. Thanks for sharing your experience.

Have you isolate the source of water leak? You’ll need to fix that to get rid of the Empty Tray error
