In my case the brew group is jammed in the down position - so I could not remove the grounds bucket. I think error 8 may be when the motor is stuck (over taxed) or the brew group is out of position. I opened up the right hand side after removing the back with the jura oval key tool https://www.jura-parts.com/ then removed the metal panel with a tiny torx head screwdriver I could manipulate the cog on the screw thread with my hands - it was very tight. Lubricated this and it seems to be working now.

its a grinder group fault , the seal on the internal group head (the part that compresses the ground before brewing) has stuck or gone dry from lack of use. if u gain access to the internal of the machine( may need a special tool, oval head srews) grease with food grade lube, the red/orange seal on the long 45 degree cylinder inside. u can manually turn the gear by hand once inside. If still a problem check the motor that drives the same unit.

Malfunction 8 means that the brew unit can not get in the right position in the right time. This is usually because the brew unit is full of old coffee grounds. Try to shut down the machine for one day. The next day, take out the tray and clear out all coffeegrounds inside the brewunit. Use your fingers and maybe a small towel. You can do this right away, but it is easier when everything`s dried up. When all this is cleaned up, start manually a Cleaning program. This should solve your problem.
If it doesen`t, i could be that the o-rings inside the brew unit is defective and needs to be changed.

Error 6 means that the automatic ceramic valve having a problem reaching the right position. This is usually related to the main electronic board and there is a chance that this needs to be changed. There could be a possibility that the multivalve is broken, but if you can hear it turning when you start up the machine, it`s probably ok.

Hi, if you havn't already solved this one, it has been caused by pulling the drip tray/ dump box out while the brew unit was still active. Switch off the machine and insert the drip tray without the dump box. Turn the machine back on and the brew unit should re align itself.

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! I was instructed to remove the whole 'drawer assembly' and remove the grounds bucket. Insert the assembly without the bucket. Wait a minute, take it out again and replace the bucket. Then you're ready to go. Hope this helps.
