James Hoffman (Jimseven) wrote a blog post on this in 2009. I have it printed in his "Best of Jimseven" book, but I could not find it online anymore. The title was seasoning a machine / grouphead (or something to that effect). Here is the only reference I could find on his article.

Essentially his theory has no, he was not convinced that you need to and had a compelling breakdown of why. Perhaps you can find his original blog post somehow.

Not sure why, but the old stuff is hard to find without knowing that the old posts are now on jimseventemp.wordpress.com

I always thought those directions sounded like a load of crap and never bothered with it personally. And I never had a shot that tasted like detergent.

I'll go out on a limb and assert that lawyers were behind this recommendation. :lol:

I'd say it's advisable if you're Cafiza's primary audience: commercial cafes. Having tasted that first shot after an auto-backflush before, I know there's a realistic chance that it has an aftertaste of soap. For that reason I'll always pull one into the drain pan just for some extra assurance than I'm not tainting the flavor with detergent.

At home? Just rinse a bit longer. Taste a drop of water from the group if you want to be sure it isn't soapy.

I've got a bag of old grounds that I'll use post detergent to purge/clean before I put the good beans in. The bag is just a collection of beans gone stale when switching to a new batch
