Neff C7660N0/03 "Empty bowls" remains

Hello,

I descaled and cleaned my C7660N0/03 machine today (grease dissolving tablet) and now the last "empty trays" won't go away. I have completely cleaned and dried the drawer. Nevertheless, the display always jumps from "Trays missing" to "Empty trays". I don't know what else I can do. The instructions don't give any help either. The machine is no longer usable and is "virtually" defective.

Thanks for your help.

Could you shine a light from the front to see if the contacts are damp. I don't know the Neff, but the drip tray has two contacts, and if there is moisture inside the machine on the detection springs then the message will also appear.
