How to Disassemble and Open Jura Z5, Z7, Z9 Coffee Machine 

The best video on how to dismantle a z5.Great explanation easy to follow and no technical garbage.Explains what does what excellent thank you.

Thanks for the great video, I took the brew group appart, cleaned it and changed all gaskets according to your instructions. Worked like a charm!

Wonderful video

Hi..when i make a cappucino there seems to be steam coming out before the pressure builds up...could this be a faulty ceramic valve

This is a great video! Thank you! My machine is intermittently brewing coffee, and then at other times passing water right to the tray. Sometimes it makes a partial cup of coffee and just filter the rest of the water to the tray. Do you know what needs to be looked at or replaced? Starting to take the machine apart now using your video.

Those Torx screws on my machine are T15

Any chance posting Jura Z8 complete disassembly? Having hard time to remove the front panel. Thanks

Can you please tell me which oval head screw driver i must buy to open the machine? Thank you very much sir!

I have a Z6. Does anyone what is the MOSFET located on the PCB, Q49, is? Mine blew off.

The logo will not rotate. Any advice about how to get it to open?

Thanks! I have a problem that the Z5 don't fill up with water (fill system) pump activates and humms for ~10seconds and then stops, stills showing Fill system after that. I think all water ends up in the tray Is that pump membrane or valve problem you think? /Stefan

Thanks, keep the Z5 videos coming!!!

Wonderful explanation . Thank you for taking time for making and uploading this Video.

Thank you. Very informative

très bonne vidéo, merci

Thanks guys great video it helped me fix my problem and now I am enjoying a sweet flat white. Cheers.

great video

that was fascinating!

Just to follow up in case anyone has similar problems in the future, I borrowed a portable appliance tester (plugging the machine into an RCD socket will do, to save you tripping your mains supply repeatedly). I was able to see that the machine was failing insulation check. With the machine dissasembled , sides, back and top removed, I systematically unplugged the obvious items...heater units, transformer etc, checked the mains cable was not shorting etc. Then looked at the power pcb on the back of the machine and disconnected the molex connector with the heaviest gauge wires, as I assumed these would be the ones carrying current, not just over or signals(to isolate all feeds out from the pcb). The unit then did not trip the mains supply, so I followed each of the 7 couloured wires from the plug to each device on the machine. Finally stripped down the grinder assy and disconnected the grinder motor - bingo! The motor assy and wires were coated in a film of coffee oil after years of grinding, so I wiped off the oil from the motor assy, used an airline to blow out any debris from the motor windings (and gave the grinder assy a good wash down while I was in the area). I had the motor insulation tested and it was found to be fine after it had been decontaminated. Reinstalled the grinder assy,plugged in and machine powers up as it should. I just need to recalibrate the grinder now with a few sample cups, but so far it’s looking good. Z5 is back alive!

Hi Parts Guru, very helpful video stripdown. I have recently replaced the 3 way pressure check valve (between pressure relief assy and boiler) due to a leak on Z5. Machine was all dried out and repair carried out fine, machine used for the last 3 days and all fine until tonight when the machine tripped out my RCD. Suspecting another leak I have disassembled the machine again to inspect it internally, but it’s 100% dry, no leaks, now pooling of water. I’d just had a good coffee from the machine when a few minutes later the power in the house tripped out (possibly coincides with 10 min delay before milk nozzle rinses?). The machine will not even power up now to get it to a start cycle, immediately trips out the 240v. I have inspected the mains power cord for any damage and internally machine is clean, dry, no obvious overheat marks, transformer looks like new, did not hear any loud bangs and cannot smell anything that suggests component damage....any suggestions on where to start fault finding? Thanks you in advance, keep up the good work!

Now that we know how to remove the brewgroup, can you make a video on how to clean and oil it without taking it completely apart into a million pieces. Just for basic maintenance. Perhaps soak it in sudsy water , and then oil certain sections??

thanks, this assisted me in getting into the boiler area

very helpful video. Is there a special tool for removing and installing metal hose clamps and collars?

Thanks for your great videos. We have a Z5 that has recently started tripping the circuit breaker. It will do it only after completing a cycle of making coffee. No leaks anywhere and after resetting the breaker it will work for another coffee. Doesn't trip the breaker every time only about half the time. Any thoughts would be appreciated. thank you

I suspect the heat exchanger is clogged is clogged in my Z5. During rinse cycles a lot of hot water ends up in the drip tray. How do I clean this? Does it need to be removed and cleaned manually?

Hello There Mr Guru! Thanks for the great videos! My Jura Z5 made a popping noise from inside now will not power up at all. Tried the the plug but no luck. If the thermal fuse to the main thermoblock. will that cause a total machine power failure? Andrew B

what is the trick to removing the jura emblem on the back of the Z7 to get to the screw underneath? Pressing and turning clockwise did not work for me. Really enjoyed the video!

Hi our old Z5 is no longer filling with water. It was getting very slow and when we replaced the filter cartridge now no water goes through at all. We can't get to the manual decalcifying function. (Under "Maintenance" everything except "decalcify unit" shows up on the panel.) Now it only shows "system fill" every time and does not make coffee.

Hi David...Thanks for the awesome video! I heard a loud pop from my Z6 this morning. Turns out I have a blown hose from the pump to the steam boiler. Is this just a symptom of something else, or is it common to see a blown hose? Also, my machine has 5000 espressos with steamed milk, 3000 pre-ground espressos with steamed milk, and 3800 steamed milk only. Should I be replacing any parts? much appreciated.

probably need parts ! my Z5 is only making 1 tablespoon of coffee for single, but double is fine . I regular get parts and keep my machine clean. The spout on left has been spitting 1 tablespoon of coffee for a while. Need some help please

I have a 2007 Jura Capresso Z5 is there a way to see how many cups I have made to date?

Your site is very helpful. Plus with the order of the Jura service tool I was finally able to make a repair with the parts I ordered. The grounds scraper replacement from brew group. Now all is working but a new sound has come up. At the beginning of a cup brew cycle the is a load buzzing that goes away half way through the cup. I can hear and feel its coming from the lower right side rear of unit. Is it the pump or diaphragm?

Where can I get the oval torque screw tool? Thanks T

If the water is not constantly flowing from the water tank to the pump, the pump makes the loud noise. You should also descale the machine.

My Z5 was leaking water and now it trips the breaker when making a cup of coffee. Where do I start to look for the problem?

What home top end completely automatic (auto grinding and auto milk steaming) latte machine would you recommend for least maintenance and best use? We have Jura and have had trouble and would like to have easier time in future -- thank you for your help!

Thanks for posting this video. I'm considering buying either a J6 or C9 machine. Any particular concerns about either of these machines in terms of them being problematic? Can you comment about the quality of the Jura products compared to any of the other companies that make these style of units? Thanks, David

Hello! How to adjust manually inside (without top on machine under cover) grinder? Because it makes not fine. Thank you.

Hi, when the z5 throw water out after not being used for a while, what can it then be ? cappuccino side ok, but espresso etc is problem and it will throw the water. Hope you can tell me ;)

Hi David. We don't recommend Jura machines as the brew group in these machines is not accessible unless you take the machine apart. Over time, the brew group gets dirty and clogged due to used coffee grounds and cause brew group malfunction.

My Z7 will not power on at all. I checked the plug-in and it works. Any suggestions?

Hi guru, I have a Jura z5. It’s 10 years old. It’s been working good over last decade. But now sudden it stop working. There is no power at all.

hello, on the new Z6 model making a hot milk cup is coming out warm/cold even if i set the temp to 10(max) , Jura says this is normal as the milk temp controlled to 140 max. but i find this disappointing for a 4000$ machine, do you have a trick to increase the milk temp or make the thermoblock heat the milk further ?

Hi, can you tell me, what's the right thermal sensor indication, when the coffe machina is off and after that when the coffe machine is on a work position (can you measure the resistance).

I heard a loud Poof sound while making a latte this morning and then water went all over my counter. I watched this wonderful video and im thinking it would be a pump issue. What do you think? I know you haven’t look d at it but since youve worked on so many of them- just curious. Btw- i just ordered the special Jura tool to remove some of the screws- so hope to be able to open my machine up soon and get it fixed. The next machine I get is going to be the one you guys designed!!!!

I have jura giga x7c.today give error 14.what does it mean please?

I am having the exact same problem with my Jura Z5 that Frederic Valiquette mentions in his post from a year ago. My milk froth button and cappuccino button only make two beeps when I push them, but don't do anything else. The rest of the machine works fine. I have decalcified the machine twice and cleaned it with tablets twice, but nothing has worked. Help! Please!

Hello sir, kindly look at my video and share your ideas, what could be wrong. My Jura Capresso Z5's milk frother doesn't work. When I press the milk button, all I get are two beeps and nothing else. Other functions work well: Espresso, Coffee, Water and even Capuccino rinse. There are no error codes. I tried to reset the computer by changing the language, 30 minutes power unplug. Any comments or suggestions would be appreciated. Thank you!

I had exactly same problem as Michael George described. I couldn't make cappuccino/late. The machine would start pumping milk then stop after couple of second with "SYSTEM FILL" message. As long as I could make regular coffee - I didn't attempted to fix it. After a couple of month I started to get "SYSTEM FILL" when trying to make regular coffee. At the beginning machine tried to pull some water and after several attempts it just stopped. I changed the filter, pressing button for System Fill, get message System is filling. The machine doesn't make a sound and "SYSTEM FILL" shows up again. Please help. What could be broken? Where can I get the parts to replace. Thanks in advance
