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.

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.

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.

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.

I had a similar problem. I took off the side and rear cover, followed the hose that comes from the steam wand to the rear of hte unit. It enters a solenoid made by ACL Italy. I dismantled the solenoid unit by disconnecting the two hose ends, removing the relay, and unscrewing the plunger unit (vertical pipe). The plunger unit internals should move freely up and down like a piston in a cylinder , powered by a small spring. In my unit, this plunger was calcified and seized. I soaked it in boiling water and pressed on it gently several times and it unstuck. I put it all back together again and presto! Good luck
