This is prob a really dumb question, but bear with me.

I had no idea I was even meant to back flush the machine.  That is a huge reason we had to pretty much take it apart to thoroughly clean it.

Anyway, all the YouTubes I am watching have a 3rd area for water to come out while back flushing.  The KA does not.  It has the portofilter area and the steamer wand.

How do I do this?

Not a dumb question.

AFAIK, Proline espresso machines lack three-way valves and cannot be back-flushed.

Hmmm....
This is a truly terrible graphic, but it looks to me as if the KA Proline does have a 3-way

Edit...

And, in fact, you can see it at least one of them in a picture the OP posted of her KAP

And maybe this second picture is of the one on the boiler....

As I understand it, the KA does have the 3-way and I have read of people actually back flushing, however, they haven't actually posted HOW to do it.

Unless I have missed something altogether, and admittedly I have never seen a Pro-Line, but I think the backflushing would be the same as for any Gaggia which has a 3-way solenoid (the Classic and some Babys).

This should give you what you need:

No, I am the one missing something.  I am reading that and it says to back flush until it is free of residue.  How do you know?  Where does it come out to see what is coming out?

Aren't you using that flat basket with no holes (blind filter), so there is nothing coming out in the portafilter area, so where is it back flushing to?

Okay, go to PartsGuru (http://www.partsguru.com/KitchenaidGaggia.html) and look at the parts diagram (it is much more readable than the one I linked you to before) and also read the directions for backflushing.  They should be more accurate than the ones I linked you to before, as they are specifically for the KA.

I think the discharge from the solenoid on the KA may be hidden in the housing.  I suspect that it goes from the solenoid through part #66 on this diagram and then flows into the back of the drip tray.  There should be some pressure exhausted there at the end of each shot if the solenoid is working.

And that is way more than I actually know about KAProlines, so I am going to sign off of this thread and hope someone who actually knows something to chime in.  

Good luck.

Sounds like you solved it, but at page end on the parts diagram

http://www.partsguru.com/user/kitchenaid-espresso-artisan.pdf

Parts 24, 26, 41, 30, and 29 seem to connect.  It appears that 29 is passed to the drip pan 50, in front of the tank in the upper diagram.  When I back flush with cleaner the first return or two are very dilute coffee color. If I empty the tray and repeat, the water in the drip tray will then be colorless.

Sorry if redundant information.

THANK YOU!

Now I get it.

It is rather hidden.
