The outdoor patio is directly over the dining room and there has been some water coming though. The home was built about 30 years ago and there is NO rainscreen in place.
I cut open the inner wall today and they were dry inside. I think the problem is related to the patio floor (suppose to be concrete over some type of ashpalt pan) or maybe the water is coming through the wall, if that’s possible?
I was thinking I could block the drain, fill the pain up with water and see if there are any leaks.
Any ideas?

pain is an appropriate Freudian slip

Wow. Isn't there enough rot in these photos to already lead you to that obvious conclusion?
This project has a number of moisture related issues. Absence of a rain screen venting detail wouldn't top my list.
first off, what is the round thing in picture 7??? looks like it may jump down and bite.
Image #5 -the flashing at the base of the siding looks like it has had some touching up with tar, and matching sealers. How good is the slope on that slab?
-the water damage on the door looks to be from rain splashing on the slab, covering the patio with a simple roof may be something you need to look into and would give you a large leg up against water in the long run. you could continue the existing roof line, or do something below it.
Image #7 is that water damage the place where you notice water infiltration?
Where is image #2 in relation to the dark water damage shown in #7?
Sequel in the making

It looks like an oversized brain. Sigourney Weaver should becalled in to oust that resident alien.

Yeah, where is image 2, and where is image 5?
If image 2 is a shot under the planked deck then it appears likely (and consistent with 7 and 8) that water on the deck is essentially spilling over the edge of the concrete, right into the rim framing.
Weird design.
More Explanation
Pictures
#1 - Exterior view of patio
#2 - Looking at the corner where the drain is
#3 - Inside the dining room
#4 - Siding profile - channel type, the water pools
#5 - Door leading to bathroom, damaged by excessive water
#6 - Rail cap - Odd design, it actually has a flashing underneath it that goes over the edges of the siding. When removed it was either rotted or completely wet
#7 - Looking up to the inside corner. Yes there is a bee's nest.
#8 - Inside corner
#9 - Inside the wall of the patio, looks pretty dry
In speaking with someone from Schluter they think that the torch down membrane underneth the concrete drain pan has failed.
30 Years Ago Huh?
Looks like it's survived longer than the builder had intended. The rest of the structure date to the same era or was this porch / dining room an addition?
Failed torch-down membrane under concrete's the least of the likely problems.
You appear to think the interior wall cavity in #9 is pretty dry while that white stuff in the corners at the bottoms I suspect is some kinda fungus living off the cellulose in the adjacent wood components. It may look dry but how far into the wood can you push an ice pick?
You lucky enough to own this place free and clear? Otherwise it could cost you more than your equity to get it rebuilt to contemporary design standards.
A proper fix will most likely mean a gut job. You will have to remove cladding on the house wall abutting this deck in order to expose the deck's wall connections. These intersections must be flashed properly. Then the deck itself must be torn out and rebuilt. A membrane (epdm, tpo, etc.) can be installed along with all the associated flashings, drains, incantations to the weather gods, etc. The list goes on and is really impossible to say without actually being there to make a complete survey. After demo, expect a few more surprises.
If you try to skate by with caulk or roofing goo, you will only delay the inevitable. Things aren't going to get better by themselves.
