Keeps saying empty tray

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 ?

try taking the tray out and leaving it out for like 2 hours with the machine still in the on position. mine has done this before, when i reinsert the tray it will go back to select coffee on the menu. FYI - there is like a built in timer for the tray removal - I believe it will tell you what the timing is in the booklet - howver it works best to do what is stated above.

alignment error usually means that one cartridge is not printing, or paper tray is empty.
try removing both cartridges then stamp each printhead on some folded tissue paper. You should get one solid strip of black ink with the black cart and 3 colour strips with the colour cart.
If you don't...there is your problem.

good luck

Open the preground coffee lid, drop a cleaning tablet in it, let it do it's tablet cleaning cycle. After cycle empty water out of tray and clean.

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

Shut down everything, printer and computer and try again.

I think the microswitch that sensors the front door is not activated. Try to find it and "give it a massage" The machine resets the counter for the grounds container every time the door switch is activated.

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 skanky!.

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!! :0)

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:)
