Just cleaned our Thermador BICM24CS Coffee maker but we get an error message "empty trays". I emptied them, cleaned the contacts, reset the start button. Still has that error msg. If I remove trays the msg says "trays missing" which is correct. Anything I can do to fix this?

This just came up on our Thermador Savor built in coffee maker. I put descale in tank but accidentally pushed Clean button, rather than Calcif!! So I hit the off button...but it stayed lit green...and EMPTY TRAYS would not stop!! The trays were empty!! And I could not hit the on off button...it stayed lit green and EMPTY TRAYS continued. I had rinsed contacts, even. I can't find original answer in here right now...but I thoroughly wiped the contacts that are in the back of the tray...but there are contacts in the "front" as well. DUH! They are on the sides of front of tray. Wiped them down..lo and behold, EMPTY TRAYS went away, and now I am descaling the machine!! Oh, I also do the clean/calcif myself monthly, and I don't wait for the machine to tell me! I received this advice from foxy also. Life is good again!! Thanks FIXYA!!
