Delonghi Magnifica rapid Cappuchino

Hi all
,have a 04.320 s.It had the error message grinding quantity too fine.
After an intensive descaling and maintenance of the machine everything worked again.
The coffee puk in the pulp container is thin and watery.
Have the reed board, power board and the grinder renewed.
Unfortunately no improvement.
Only when I fill the brew group with powdered coffee and then draw a coffee with grinder, the brew group breaks off, so I force this to reset.
It comes then of course the error message coffee quantity too fine.
The following coffees are perfect also from the size of the coffee pouch.
As soon as the machine is switched off and on again, everything is thin and watery again.
I hope someone here knows some advice.
