Jura Impreza E8 - only water comes out no coffee

2 things descale the unit as per user book or make the grind coarser. this is done in or near the coffee beans container. turn the knob in the direction of the larger dot or bean symbols

Too Much water , use less water .

Too much water .

this was absolutely the problem with my Jura Capressa E-8 machine. I followed instructions after changing the filter. I opened tap-machine stated that it was filling system- I closed tap when instruction. The open tap remained on because no water was filling system. I took the frother tip off and opened tap. Water filled system (container under frother). I closed tap without the frother tip. Machine Ready.... (I heated water in microwave for three minutes) I placed the frother tip in there and used a wooden skewer to ensure frother was clear of debris... Worked like a charm!

Usually water in the grounds container is caused by the coffee solenoid valve return side being blocked from dry coffee. Using cleaning tubelets to clean the coffee grounds out. If that doesn't work then you should remove the solenoid and clean it out with warm water. If that still doesn't rid you of the wet grinds you should have a certified repair tech take a look at it. You may end up having to replace the solenoid but that should be verified by a tech before you spend the money.

It seems withthis model you have a 1 year or 4000 cups warranty with this.
If you are within this, then give them a call - here is the Manual if you don't have it -

I suggest you start by removing the beans in the hopper and wiping around to remove oils.
Then refill with fresh dry beans.
Plug in and set up as normal
Set to brew a standard large cup - and adjust grinder to coarse setting while grinding.
Do not adjust with grinder quiet - it must be done while rotating.

Make at least 10 cups this way at the coarse setting.

I think what has happened is that damp beans (frozen or cold) have entered the unit and caused the coffee to gum up at the top of the burr.
This will just push fresh beans out of the way instead of starting to grind them.

If you use dry (light loast) beans, it doesn't seem to happen as much.

Just ake sure you refrigerate most of your stocks, but keep a small stock at room temperature in an airtight tin to prevent this kind of thing.

You can actually push down on the bean stack slightly with a wooden object while the grinder is running if nothing moves on the coarse setting to get things moving.

Did anyone find an answer to this - sadly we have the same issue.

Jura Capresso E8 Makes a cup of espresso then makes a gear grinding sound and then throughs an Error * on the screen. Machine was repaired by Capresso a year ago.

Do you seem to end up with more water in the tray now then you did before this problem started? Does your coffee seem weaker then before? If so I have some ideas for you.

Simple fix - got the machine serviced, needed a new thermoblock apparently, could also have been one of the couple of sensors they replaced. Total cost including box, bits and carriage - £180 plus change.
Expensive but now I have it back, it all seems worth it!
