Question about Jura Capresso Impressa F9 Espresso Machine

7 Answers

Malfunction 8 When the unit is turned on, the mechanism for dumping and smoothing out grounds in the waste bucket starts. It runs three cycles of this, and ultimately ends with the warning "Malfunction 8." It cannot proceed to making coffee. When I remove the tray and bucket (holding in the white lever so the "Tray missing" warning does not go on, I can see the grounds-smoothing levers moving. Might something be caught in the mechanism, keeping these levers from finishing their job?

    I had the same problem this tuesday. Basically all I had to do was to empty the tray and grind container as well as unplug and plug the unit then run a rinse cycle and everything is back to normal.



    Hope this helps.

I just fixed it. I saw some info from a Doctor in Hawaii who described reaching up inside the machine with some success and this inspired me (Thanks!). I had been getting Malfunction 8 for some time, and letting the machine cool (turning it off) for 15 minutes was the only way to not get the error. It always sounded like it was "straining" to make coffee. It would generally try 3 times to clear itself before the Malfunction 8, I'm sure those with the problem will recognize the symptoms. All the rinse/ decalcify/on/off stuff was temporary. We lived with this for 5 months or so. Finally, it would only get a Malfunction 8, and so became unusable, and we were considering sending it in for repair. This was the second round of Malfunction 8 problems; the first seemed to fix itself for an unknown reason. On to the fix: Unplug, remove the water tank, pull out the bucket and tray, and allow to cool if necessary. Now - smaller fingers are better - reach into the machine, palm up. Feel as far back as you can, then work your way forward, toward yourself. As you move toward you will feel a flat area about an inch wide (measuring front to back). Just back of this (away from yourself), you'll feel a crack about 3/8" to 1/2" wide. Push your fingers up into this area and feel around. You will probably feel stuff that feels like light, chunky rocks. Break these up and they should fall out. Again, small fingers are better and once I got an idea of what I was doing, I described it to my wife and she did it. There is a tendency to not feel far enough back in the machine, so be sure to find the flat place at the lowest point of the mechanism then go just past it and up to find the crack. Pulled out about five crusty chunks of burned, almost charcoal like compressed coffee. I also got about a foot of plumber's tape (the metal stuff with holes in it that's useful for just about everything) bent it with a 4" radius, and worked it up into the crack to break up any stuff we couldn't reach. Work at this until no more stuff is in there. Now, tilt the machine toward you and "pat" firmly all over to jog anything left into the crack area, and check for chuncks again. When that's done, put everything back together, move the machine to where you can work from the top. Don't start it up. Get a flashlight and a wooden spoon. Open the top "pre-ground" door and peer in. With the wooden spoon handle, poke in there and tap everything to break up any stuck things. I thought a shopvac with a small tube might work here, too, but wasn't sure whether something bad might happen. Anyway, tap tap tap about 100 times. Now start up the machine. Keep peering in; watch how the mechanism works, and don't trap the spoon handle! Now, try to brew some coffee. While it's actually squeezing out the coffee, tap some more on the "closed" mechanism to free up any more stuck coffee. Do this whole procedure 3-4 times to be sure, but don't drink any of the coffee it brews: The first ejected puck looked really aweful - it looked like about 1/3 moldy coffee; of course the machine had been sitting for 3 weeks, probably stuck in the middle of a puck ejection cycle. Anyway, the machine should run good as new. Good luck and please comment as to whether it works for you. - Woody

    Really helpful, thought I was going to have to send my F9 to Jura. I was afraid I was going to have coffee withdrawal. One thing I would add, we pushed the white button inside that senses the tray to access the front of the tamper to clear the compressed coffee. Machine working great again.

  • Doug Nelson Oct 13, 2012

    I didn't have to go through the whole process but working with my fingers I was slowly able to break down the "hardened" chunks. Thanks!

  • B. Cole Jul 04, 2013

    Thanks! I was ready to order a new machine. In addition to the above suggestion, I took the machine to the sink and used the spray nozzle and thoroughly cleaned out the bottom part. Works perfectly now.

  • Chris Aug 07, 2013

    It worked!!! Great advice and description. I used q-tips instead of my big fingers. No rocks, just a lot of goo and loose grounds. I was able to finally run the cleaning cycle. Thank you so much for your post.

Just called capresso and spoke to customer service rep. He had me take the bucket off the tray and then run 'maintence.' That resulted in a coffee 'puck' being dropped into the tray. He then had me reach behind the plastic part that hangs down and clean the metal disc that tamps the coffee. Finally, he suggested that we run a cleaning cycle using one of the tablets as Malfunction 8 indicates a clog in the system. So far, so good.

Had the same problem - reached into the unit from below as you described and did get some crumbled coffee "rocks" out. But it seemed strained to move the parts and got stuck with "malfunction 8" even after multiple rinse cycles. So I decided to lubricate - with water that I poured slowly into the "ground coffee" opening. About half of a small espresso cup. That did the trick. Repeated that a few times and more old grounds were flushed out.

    Here's my fix after many months of the machine 'groaning' and many 'Malfunction 8' codes and associated shut downs.
    I removed the 4 oval head screws from the back (replaced with stainless Phillips head), the 2 torx screws under the water and bean lids, and lifted off the top. Vacuumed the insides as much as possible and even used a plastic tube attached to the vacuum to get into small corners. Then I lubricated the moving parts. I used "Petrol Gel", a sanitary, food service suitable lubricant, on the large plastic screw, gears, and the rails that the unit moves up and down on. The reduction in noise was immediate. If you leave the collection tray in place you can operate the machine and watch the mechanism working. You can even unplug the machine in the middle of an operation (rinse or grind) and it will stop to allow you access to places to lubricate that you can't reach with the mechanism in its' normally 'parked' position.
    After many months of listening to the machine groan and strain to make coffee and often times just stop with the 'Malfunction 8' code, the machine now operates quietly and smoothly. I feel this has solved my problem and hope it works for you as well.

  • bassamb Jul 24, 2011

    Pouring a glass of hot water into the "ground coffee"/tablet compartment while the machine is trying correct itself definitely works! Nothing else needed in my experience.

  • Ferris2612 Aug 03, 2011

    The hot water poured into the ground coffee funnel also worked for me. The machined moaned and groaned and then spit out a puck of grounds that evidently was binding the grounds ejection mechanism.

  • beansNwetvac Aug 07, 2011

    We also had a "Malfunction 8" error and was able to get the machine back in working order. We unscrewed the 4 oval head screws using vice grips from the back and the 2 torx screws from under the lids covering the water fill and bean fill. Then we washed the gears from the top with the lid removed and washed the front from below through the entrance tray area with the entrance tray removed with a hot water sprayer.

  • nanart236 Aug 09, 2011

    Due to a Malfunction 8 error and unable to get our machine running, I found your comments about pouring the hot water into the ground coffee compartment. It worked beautifully and I finally got my morning cup of coffee!! It was amazing how many old grounds came spewing out.

I got a Malfunction 8 during tablet cleaning.
I unplugged the machine for a few minutes, then plugged it back in.
I started the cleaning cycle again, by pressing and holding the Maint button.
It began the cleaning and at one point asked to empty grounds. I removed the tray, discovered that I had not put the grounds bucket in the machine. I put it in and the machine completed the cleaning cycle.
my machine is 3 years old; I had a malfuction once before and the tech rep that I called told me to unplug and plug the machine back in, then go through rinsing. It cleared up the problem.
I could not find any malfuction error message documentation, it is Sunday morning, the help desk is closed, so I tired the same unplug/replug. It worked.
good luck.

Twice now this has happened to me - probably cycling more than three times but as you say it eventually ends with a Malfuntion 8.

I believe the mechanism for dumping grounds becomes stuck as is evidenced by my being unable to remove the tray (the mechanism is down and the grounds bucket snags on it.) I am unsure if the mechanism is down when the malfunction message shows up on the display and the cycling quits.

Often I get worried that something is going to burn out with the constant cycling and I unplug the unit before it gets to Malfunction 8.

Both times my F9 has exhibited this behaviour I have found that (being careful to unplug the unit first) if I pull the tray out from under the grounds bucket and then remove the grounds bucket, a combination of dry and warm air from a hair dryer on low and some gentle tapping around the case will cause some moist puck of coffee grounds to eventually crumble and drop out.

I reassemble the unit (it takes some time to get the grounds bucket into position since the mechanism is down and then to slide the tray underneath it) and then plug it back in and the problem is gone. The first time I did this the fix lasted for at least six months. The second time only just occurred, but a larger amoung of old grounds came out.

    I have a 10 year old F9. During the cleaning cycle I did not push the door all the way in during the cycle and it pushed the door out and had the Malfunction 8 appear. I followed the advice below for unplugging and then starting without the grounds tub. I re-ran the complete cycle to make sure all was functioning properly and just ran a few cups.. all good! really glad I found this forum.

Malfunction 8 is related to the brew unit typically. It is usually an indication of the brew unit motor having to work too hard to move the brew unit up and down. This is usually cured by disassembling, cleaning, replacing any o'rings that may be bad, and lubricating the unit, then reassembly.
I have had to do this twice on an an E75 and an E8. I finally broke down and bought seal kits and food grade lubricant for doing this. (I have only been able to buy parts from Europe online) One could by a new brew unit off of e-bay and change out the whole thing. But a simple cleaning or rebuild will typically suffice. One note. The cleaning tablets tend to strip the lubricant from the inside of the brew unit over time. Ocassionaly the seals in the brew unit will fall apart and bind up the unit. Either of these is usually accompanied by a sound of the brew unit motor straining to cycle the machine.

Error 8 is a general error for not being in sync. There is a encoder disk that tracks where all the mechanical pieces are during the process. When they are not where they are supposed to be its an Error 8. This can be caused by a jamb, being dirty, faulty sensor... lots of stuff. Probably means your unit needs to be cleaned.
The quick way to fix this is pulling the cord out of the wall and wait a few seconds and plug it back it. This will cause everything to reset and usually clears the error... until you can clean it.
If you need help, parts guru has videos on youtube, parts and will rebuild you brew group for you. I have repaired mine 2x.

Jura Capresso Impressa F9 'malfunction 8' fit without dismantle


Malfunction 8 is related to the brew unit typically. It is usually an indication of the brew unit motor having to work too hard to move the brew unit up and down. The mechanism for dumping grounds becomes stuck from coffee grounds not properly waste out. This is usually cured by disassembling, cleaning all the coffee remains behind group, replacing any o'rings that may be bad, and lubricating the unit, then reassembly.

Also some coffee might be on the opt sensor that senses the up/down position of the brewing unit which when it's switched on the mechanism is not synchronizing and it will go all up or all down and show Malfunction 8.

Here is how to fix it without completely dismantle the machine:
Unplug, remove the water tank, pull out the bucket and tray, and allow to cool if necessary. Now - smaller fingers are better - reach into the machine, palm up. Feel as far back as you can, then work your way forward, toward yourself.

As you move toward you will feel a flat area about an inch wide (measuring front to back). Just back of this (away from yourself), you'll feel a crack about 3/8" to 1/2" wide. Push your fingers up into this area and feel around. You will probably feel stuff that feels like light, chunky rocks these are dry “coffee ground”. Break these up and they should fall out.
Again, small fingers are better and if yours are not once you got an idea of what you are doing, you can described it to someone with small ones and can do it. There is a tendency to not feel far enough back in the machine, so be sure to find the flat place at the lowest point of the mechanism then go just past it and up to find the crack.

Pulled out all compressed coffee “coffee grounds” you can fill. You can also get about a foot of plumber's tape (the metal stuff with holes in it that's useful for just about everything) bent it with a 4" radius, and worked it up into the crack to break up any stuff you couldn't reach. Work at this until no more stuff is in there. Now, tilt the machine toward you and "pat" firmly all over to jog anything left into the crack area, and check for chucks again. You can use a vacuum cleaner with slim tube so you can remove as much as possible with it also.

When that's done, put everything back together, move the machine to where you can work from the top. Don't start it up. Get a flashlight and the vacuum cleaner with the slim tube. Open the top "pre-ground" door and S**K everything out.
Now start up the machine, watch how the mechanism works, now, and try to brew some coffee. While it's actually squeezing out the coffee, tap some more on the "closed" mechanism to free up any more stuck coffee. Do this whole procedure 3-4 times to be sure, I suggest don't drink any of the first coffee it brews. Anyway, the machine should run good as new.

Good luck and please comment as to whether it works for you and vote for it.

This is the 2nd time in a month since I've had this machine that I had to call support for the same problem. An easy fix!

The tray will not fit back in the machine, its jammed and I don't know how to reset the machine on a Jura F9


This happens when the try is removed before the brewing unit resets fully.

To fix is easy.
  • Remove tray,
  • Lift off grinds bin from the tray
  • Return tray to the machine with out the grind bin
Now you need to reset the brewing unit this is done by either
  • Starting a rinse cycle
  • Powering off and then on
Once you have don that return the grinds bin to the tray and it will go in.

Malfunction 8 On Screen


Likely cause of this is a blocked worm drive. The worm drive takes the coffee in and then, after brewing, ejects the used grounds into the Dump box. Over time, coffee grounds accumulate on the worm drive and eventually jam it. This is Malfunction 8. Machine will need to be stripped and cleaned. Hope this helps.

Malfunction code 8 on Jura Impressa s8


To fix this problem you need to clean the layers and layers of coffee mud off the plates that dispense the spent grounds into the hopper. My suggestion is to do this major muck cleaning before you even put the cleaning tablet in.
Get a flashlight and pull the trays out and have a look at the mechanism that dumps into the hopper. You will see the layers of gunk that need to be scraped off. Easiest thing to get in there is a finger to start, then place it next to your sink and clean it with a water jet from your kitchen faucet, provided your faucet will allow you to do that. Let the runoff go into the sink of course. After you get it cleaned up, then put the machine through the cleaning cycle.
If you can't get the problem solved, the fix is a flat $200 from Capresso.
Call the number above to get set up with a service shipment, done in PA.
