Dishwasher g5600sc Miele stop mid-cycle with water intake error

Hi

I have a dishwasher g5600sc Miele that stop working for the last 45 minutes (on a cycle of 2h45).
When it stops it displays a message about the water intake (I’m french and I don’t know the exact translate of the message).
The dishes are more or less clean but not perfect.

I checked the filter in the dishwasher and the filter on the water supply. Both are fine.

It seems that next steps to try to fix it requires to open the machine but while I’m not use to it I would appreciate to have to check the less elements as possible.
Does anybody has an idea of the element(s) that might cause the issue ?
Thanks for your help and sorry for my english
