Coffee too weak

Hello all,

have for about 1 year now my De'Longhi Magnifica S ECAM 22.110.B. I'm still pretty much a layman on the subject, but I just do not get my coffee strong enough.
The coffee is usually really watery.

The grind is already set to the finest degree and have cleaned the machine several times.
I have bought different coffees and always the one that is supposed to be the "strongest".

It is now so that I have to let out a double espresso, with a shot of milk so that the coffee tastes like what.

I hope you can help me further:rolleyes:

How many ml do you have in the cup?
A guideline for 6-7g ground coffee is a maximum of 125ml of water.

Espresso 40ml und Tasse 120ml

But what brand of coffee do you use? Try maybe a medium grind.
