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.

The problem is the plastic arm that scraps the grounds off a flat round metal piece above the grounds tray. Contact customer service and they'll tell you how to clean it. Call Jura Capresso customer service at 800 220-5701.
