Jura XJ9 keeps saying Empty Drip Tray? I have cleaned/dried the metal sensors in the back and cleaned the metal sensors on the drip tray and switched the machine on and off?

If the machine says TRAY MISSING it's the contacts at the back so clean as other people have stated, you can also use a cardboard nail file to clean the contacts at the back if there really dirty!.

If the machine keeps saying EMPTY GROUNDS even though you have, pull out the tray, look just inside the aparture where the tray goes top right at the front there is a small slot where if you look closely you can see a small white micro switch. This will be probably gunged up with coffee and the switch will be stuck up, get a can of WD40 and squirt a small amount up into the switch then poke the switch with a small screwdriver up and down until it moves smoothly.

Then replace all the bits, sit down, look smug and have a coffee cos you've fixed it!!

1. Thoroughly clean the small overflow area in the drip tray. Once the drip tray gets full water flows over a small rim into this small separate part thus triggering the sensor that tells that the drip tray should be emptied. Its waals may get a bit fatty/dirty, and so remains wet and keeps triggering the sensor.

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 ?

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.

You should Clean and dry the metal contacts on the back of the drip tray, ensuring that the gap between the contacts is clean and dry (if present, contacts not on all JURA models) Make sure that the plastic in between the contacts is clean

I have a Jura Impressa 27. The tray, for some odd reason, was not going back in. I simply tried it without the top part - that receives the grounds - and was finally able to get it in. I pulled it back out and found some grounds that had been dumped. It seems something was stuck that wouldn't allow it back in with the top part. Then after I was able to put both pieces back in without a problem.

try this:clean with brus two metal contact on drip tray

aye that is true if you click the coffe making button directly after you have had it out you will be able to make a cup, as the machine has a 2 second response time.

Ok here is what i think:
As it registers the driptray I dont think its the sensor to it.
More i would think that its the CPU card that is not responding to that its clean.

I am sry but I have to ask this:
When it says emptie the driptray are you actually taking out the container that is located under the brewing unit, and not the "drip tray" were you put the coffe mugs?

Also when i think i have a sensor problem I allways take out everything. Brewing unit, dripwater container, dregbox, and the watercontainer. and have it out for atleast 2 minutes ( clean it under the mean time) and put it back again.

As I dont have the machine infront of me i cant be certain:)
