I have to keep a towel under my machine, and it is consistently soaking wet. I know about the gasket change when brew does not fill the cup, and it is not that. I wonder if there is any connection to the time I could not get the tray back in and had to push and pull to get it into place. The tray works fine now, but could I have caused some displacement? I believe it only leaks when I make coffee and not when it is idle. The towel shows only water and not coffee. Any suggestions would be greatly appreciated.
Kat346 There are a number of places were the leak could be occurring. I can't pinpoint it without see inside your machine. I maybe something like a broken or dried out oring or a cracked fitting or heater cartridge. We repair E75 www.hotncold.com

Jura does not allow access to internal parts for cleaning. Brew group is the dirtiest part as it deals with complicated movements to make coffee.
Error 8 means the brew group is not returning to start position after it completes entire cycle to make coffee.
Jura recommends to remove drip tray. Using a thin cloth, insert the hand all the way under the machine. You will feel access to the bottom of the brew group. Wipe clean the bottom of brew group as best as you can. There will be lot of coffee powder (wet & dry) that is partially responsible to prevent brew group return to start position.
A better method is to open the machine using special key. Clean & lubricate the brew group. every two months. This will prevent Fungus and Bacteria growth. .

Hi More than likely its you brew head screen. Coffee will build up on the top surface and turn rancid after awhile. Remove the screen(its either a screw or bolt that holds it on). I like to remove everything and turn the machine upside down on a towel. That way I can see what I am doing. Clean everything even around the brew head gasket. This gasket needs to changed every year for best sealing of the portafilter. Buy 2 because they always fail on Friday when you have a party on Saturday. Soak you brew head screen in hot water with a pinch of automatic dish washing detergent or espresso machine cleaner. Use a tooth brush to remove the crusty burnt on coffee residue or just buy a new screen. Clean this screen every 6 months because they should last the life of the machine.
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.
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.
If you are not savy in repairing it you may want to send it in. I suspect they will tell you it needs a new brew unit aand quote about $300 USD for the repair. About two hours, much patience, and about $10 in parts is most likely all it may need.
