Saeco Espresso machine - Empty drip tray (all the time)

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:)

Clarification: It complains constantly. Even when I empty the drip tray, which is already empty, put it back in (empty) - it still wants me to "empty the drip tray" again. Sometimes - if I'm lucky - I can brew 1 espresso before it wants me to empty the drip tray.
Thank you for your assistance!

You can also pull the drip tray out like 5 mm, and wait a couple of seconds. Then the display goes back to normal. But you'll have to check the tray manually, else you get overflow. The 'empty dreg' message is a good indication as to when to empty the tray.
