this is a diagram of the drip tray & drip tray contacts for the Jura S-Series S Series Impressa S7, S7 Avantgarde, S8, S9, S9 Avantgarde, S90, S95, C3000 capresso 153, X70, X90, and XS90 One Touch Models.
"EMPTY TRAY" or "EMPTY GROUNDS" (on other machines) is activated when the 2 metal contacts can complete an low volt electrical circuit through high waste water or wet caked-on coffee grounds. the area is marked in RED. careful examine this area and observe the obstruction and gunk and compare with bare clean black abs plastic. the gunk is dull and rough. use soft tools (toothpick, bamboo skewer) to scratch through the gunk. use warm water and soap and a low bristle height brush to thoroughly remove all buildup from this area. dry the metal contact and contacts area with a high percentage alcohol. visualize the insertion slots deep inside the machine (for the metal contacts marked 414) with a flashlight and verify that the female contact point pads have not been bent and are separate and distinct.
the GREEN arrow indicates a thin black plastic finger-like protrusion. this finger (when the tray is inserted) will press against the "TRAY MISSING" small white relay switch deep inside the machine. use a flashlight to visualize the small switch. verify that the switch is securely mounted and clicks when depressed (up) using a soft tool (bamboo skewer) and note the sound. verify the finger is not damaged or chipped off. listen for the sound very carefully when the tray is fully inserted into the machine. if it is not these preliminary factors, the relay switch should be replaced.
Hi all, I have the exactly same problem on my Gaggenau CM470 however the drip tray is clean and the contacts in the back is also 100% clean.. I wonder if its possible to disable the sensor/switch on a CM470 ?
There are two possible causes. One is easy the other is hard. So try the easy one first. Remove the grinds tray completely, and place you hand in the cavity that it normally takes up. moving you hand slowly in, feel towards the top. you will find a little flap, past that flap there is the tamper and coffee filter at a slight angle. This may be blocked, so clean with a cloth.
If that does not solve the problem (and 90% of the time it does) then you may have a small spec of dust that is stuck in the water system, this needs to be flushed and cleaned. The best place to do that is with a Jura approved center. Unless you are technically minded. Your local Jura chaps sound like they need a k!$k up their behind
Have you descaled it regularly? Do you have hard water?
Sounds like it's clogged with scale. Try running white vinegar and water through, see if that unclogs it.
Try using warm water in the watertank, important that the water is not too hot, it can cause leakage in the o-rings in the fluidsytem.
Repeat the procedure a few times, if nothing helps, turn off the machine and wait 1 hour and try again.
If you can`t get around this message, then the flowmeter needs to be changed.
Open the tap with frother spout off. This happened to mine and I took the frother tip off and opened tap with tip off. Water filled and I closed tap...Machine returned "Ready". I heated water in microwave for three minutes- placed frother tip in hot water and all kinds of gunk came out. Lesson learned- Do a thorough cleaning of frother by immersing it in very hot water at least once monthly- even if you don't use it
Remove the tray at the front of the machine.
Look inside and you will see a rubber flap which separates the right and left side of the machine.
Gently lift this to the right and look inside to the left (a small mirror like from a womans compact and a flashlight will help you see in there.) You will find a small circular screen (about the size of a half dollar.)
You need to wipe ALL the coffee grinds off of this screen. That should fix the problem.
If you use dark beans, you are probably grinding them to fine and some of the oily residue is sticking to this screen. Try grinding the dark beans more coarsely. Only change the grinder WHEN IT IS GRINDING by adjusting the litlle knob in the box where you place the beans.
If the problem started just after changing the filter you may have air in the water line and it needs to be flushed. Try running the tea portion hot water until it clears.
These suggestions were given to me by Capresso and actually worked for my machine.
Good luck.

First, I'm not JURA technician. But I have worked on similar table top "Super Automatics" You should call your vendor or the MFR for service. Especially if it's still under warranty. There are no customer serviceable parts in this machine.
*** the following is for information only ***
- Water not getting to machine or not sensing that the water tank is already filled.
* There usually some type of float near to middle of the water tank. It's usually white or colored plastic. This 'float' needs to move freely up-down to 'sense' the filled tank. clean the tank and shake it -note the movement of this float. It will need further cleaning if it's stuck (or you will have to replace tank if it's crudded up).
* Re-install tank and fill with filtered water. Turn machine off, count to 15 then turn on again. This usually turns on pump to add water to inner tank. If this does not happen then there is a CPU problem. If it does hums for 5-10 seconds then goes off but no heating then the pump may have an air bubble in line. Try the turn off and on method several times (up to 5) to get the water flowing. If it's still not working then there is a clog in the pump and will need service and/or replacement.
* Since this is a table top machine in which you fill the water tank. Try to use filtered (bottled ok) water. Do Not use Distilled or 100% pure water as this type of water will eat out the metals from your machine! Some places use a water softener as it tends to be better for the machine long term (years).
* Still got problems? Check with vendor or MFR for service or replacement. Most machines of this type do not have serviceable parts or adjustments.

PS: I've noted this tank also uses a water filter (which is probably dry after sitting around for a year as you mentioned.) you will probably have to flush out the air in the filter prior to this unit's pump to work properly. I found a youtube vid that may help:

I had this problem and fixed it. At the bottom of the bean container is a tab that extends about a quarter of the way around. This tab is designed to fit into the base inside a quarter-circle groove that rotates back and forth slightly when the bean container is installed or removed. In my case, the groove on the base was not aligned correctly, so I inserted a blade screwdriver into the groove and rotated it gently in a counter-clockwise direction until it stopped. After this, I could install the bean container as expected.
The first thing to check is the seating of your water tank. Just a few grains of coffee grounds or dirt underneath the tank are enough to break the watertight seal. Make sure the area under the tank is absolutely clean.
That's always worked for me when I've had the leaking problem.
