So, carrying over from the last time these were offered, it looks like the handles and rivets on these pans might be aluminum, and yet they claim to be dishwasher safe.
If so, that dishwasher-safe claim might now be obsolete. Aluminum is no longer considered dishwasher safe without special considerations, which I'll discuss below.
I haven't confirmed 100% that the handles of these pans are brushed cast-aluminum and the rivets are aluminum, but they certainly seem to be (if anyone has information to the contrary, feel free to correct me). They are good quality pans though; heavy and well made.
EDIT: A later comment points out that the description of the everyday pan indicates it's handles are stainless so there might not be any need to worry about the handles on those and possibly the others, just perhaps the rivets and the outside edge where the aluminum core is slightly exposed.
Additional background, which you can feel free to skip if not interested:
For those who haven't noticed, dishwashers used to be able to clean aluminum just fine, up until a couple years ago when they mysteriously started ruining aluminum pans, making them pitted, and leaving them covered in a gray or black substance that gets on everything and generally makes a mess. Not only that, it seems like even without aluminum, dishwashers just don't work as well as they used to in general.
So what changed? It was actually the detergent! Dishwasher detergent manufacturers reformulated their products nationwide to comply with new regulations in several states that banned phosphates from dishwasher detergent.
The problems with this are twofold. Firstly, the replacement chemicals simply don't work as well. Food is more likely to remain stuck on dishes, often requiring a second washing. Secondly, the new formulas wreak havoc on aluminum, which means no more washing aluminum pans or baking sheets in the dishwasher unless you want them ruined.
You can work around the first problem (not cleaning as well) by actually adding supplemental phosphate to the detergent yourself, but that still won't make the new detergents aluminum-safe.
The only real solution I've found is to go back to the old formula, and luckily, the regulations apparently don't apply to commercial dishwashers, so all you have to do is buy commercial dishwasher detergent.
If washing a particularly dirty load of dishes, or if there is anything aluminum in there I use "Cascade Professional Line" which is available at warehouse clubs or online. It cleans better and doesn't ruin aluminum. I even tried putting in an already black (from washing with phosphate-free detergent) baking pan, and after washing a couple times with the old-style detergent, the pan is actually usable again. The only real drawbacks are that it's potentially worse for the environment (though that's somewhat debatable since I often had to run dishes through twice with the new phosphate-free stuff versus once with the old style detergent), and that you sometimes have to buy 26 lbs of the stuff at a time since it's mostly intended for commercial use.
I think keeping both types around and using "the good stuff" only when necessary is a reasonable compromise between showing some concern for the environment and actually getting dishes clean (and avoiding ruining them).
