Could be bad grinder or no 12v. The display/control runs on 5v and there is a transformer (supplying 5/12vdc) where the a/c cord comes in. Mine was blown from lightening.
Try these guys... they have parts, trouble shooting and videos on youtube.

My Jura 5 was only pouring coffee from one spout, the other was blocked. I fixed it by removing the cover from the spout (see photo) it clips off with pressure applied to the sides on the dimpled part, then removing the brown reservoir inside after disconnecting the brown tube. Right enough, one side of the reservoir was full of coffee residue. I cleaned this with hot water and a tooth brush before re-assembling it all. The machine now pours perfectly from both spouts.
From your description I would say a broken O ring seal in the brewing chamber. You will need to remove the brewing unit and clean, replace seals and lubricate the sliding guides.
My guess would be that your water tank float is trapped.
The remidy would be to descale the watertank itself.
If you use the Calris filter cartridge. remove it before descaling with a mild commercially available descaler. Don't forget to rinse thorrowly afterwards and reinsert the filter. Always use cold water to fill the watertank.
Hope this helps
Sounds like you might have more than one problem.
From page 12 of the manual... NOTE THE LAST LINE.
"8. ADJUSTING THE GRINDER
......
• Open the lid of the bean container.
• While the grinder is running turn the grind selector switch to
the desired position (Fig. 6).
-The smaller the dots, the finer the grind.
-The bigger the dots, the coarser the grind.
Important:
The grinding grade can only be adjusted while
the grinder is actually grinding."
It is probably because the brewing unit has not stopped in the correct at rest position. I'm not familiar with your brand but sometimes if you remove the bin from the tray you can slip the bare tray back in under the brewing unit enough to activate the machine so it can reset itself.
Unfortunately the error message 5 indicates that the thermal block and/or thermal sensor and possibly a control board need to be tested, and likely one or more, possibly all, replaced. My recommendation is to send it to Capresso ask what it will cost first. M
So did you empty the grounds?
Pull the plug and plug it back in.
There is an encoder disk that spins around to control the mechanical movements inside the unit. Some mechanical piece is not where it is supposed to be and the circuit board it waiting for a sensor to clear. Cycling the power will normally make all the mechanics reset to the start position and clears errors/jams etc.
Check to see if there is a lever that may need pushed in as you put the tray bad in...not sure as many of the machines are different...but it's worth a try! :)
Have you tried completely powering it down, as far as unplugging it from the wall? Sorry if that's stating the obvious, but I'm a computer guy and 9 times out of 10, a 'reboot' fixes the problem.
