Krups EA 9000 control panel does not respond

- Machine turns on.
- at the "Rinse Menu" the control panel responds.
- at the main menu the control panel stops responding. However, the clock is running properly, so it seems that the control panel is not frozen.

I would appreciate any help!

With the EA I would reset the whole system times. There are 2 different service menus on the Krups EA9000.
Since I would delete everything and set up again.
The member Rudi72 has once posted:
"The first menu is accessed by tapping the four corners of the screen immediately after switching on, within 3 seconds. The order is:
Top left, bottom right, bottom left, top right.

You can get to the second service menu as follows:
After switching on, while the screen is still white, press the powder button three times.
Then after the greeting, press the powder button again 3 times."

I hope it helps you. Try the points in the service menus. The Google translator helped me with the French menu.
