Cast iron, enameled cast iron, non-stick, and most aluminum pots and pans should never be put in the dishwasher. The high water pressure, heat and detergent will remove the necessary oils from cast iron, damage or remove non-stick coatings, chip enamel, and cause discoloration on aluminum.
You should also avoid putting enameled cast iron in the dishwasher; the metal is mostly protected, but the enameled finish can still be damaged. Aluminum doesn't belong in the dishwasher, either.
If you are washing something made from metal or that has metal on it, use caution. Not all metal should be placed in the dishwasher. Below are some general guidelines; however, we recommend checking with the manufacturer of the item (if possible) to see if it can be washed in the dishwasher. Aluminum: Usually safe.
Aluminum is a very reactive metal, and the surface is rendered less active by the process of anodization. However, automatic dishwasher detergents are caustic and will attack the aluminum.
With stainless steel, acids, salts, dishwasher detergents - especially combined with heat - will cause it to rust. It should be noted that there's very few steels that are truly stainless and they all will eventually rust.

1. Never Place in the Dishwasher (& Avoid Abrasive Scouring) Copper is a soft metal that can be scratched easily, so you don't want them to clank against other items. It's also best to avoid abrasive scouring on the copper portion of your pan, though it is fine to use when cleaning a stainless steel interior.
Cast iron, steel and tin: Pots and pans made from certain metal materials, such as cast iron or steel, are susceptible to rusting and should typically not be cleaned in the dishwasher. Hand wash these items instead.
The high-pressure water jets and strong detergents used in dishwashers can scratch the surface of your pots and pans, especially those made of nonstick or coated materials. Over time, these scratches can compromise the nonstick coating or scratch off the enamel, leaving the underlying metal exposed.
First, never, ever put any Pyrex through a dishwasher. This is the fastest and most damaging thing that you can do. It will slowly etch the Pyrex, and probably will not even do a decent job cleaning it. I generally recommend that you never put any glass through a dishwasher.
In general, your pots and pans should stay away from the dishwasher. Non-stick, cast iron, and aluminum pots and pans should never go into the dishwasher.

"Like cast iron, you should not put aluminum in the dishwasher as the detergent, high heat, and minerals in your water can trigger a reaction that darkens the metal," says Peterson. Additionally, the jostling of items against each other can scratch the surface.
Handcrafted and hand-painted items are easy to damage as well. Likewise, one should steer clear of putting metal-rimmed or silver in the dishwasher, as these metals could deteriorate in the cleaning. For cast iron, copper, and non-stick equipment, it is best to follow the manufacturer's instructions carefully.
High-quality kitchen knives do not belong in the dishwasher.
Although the damage is often not immediately visible, the dishwasher will dull your knives over time. The detergents in the machine attack the blades. They contain salts that contribute to corrosion and thus to wear and tear on the knife blade.
While you're at it, avoid placing any cheese graters or vegetable peelers in the dishwasher for the same reason. A sharp knife in the dishwasher can also become a hazard if it shifts during the cycle or if you're being extra hasty when unloading the dishes.
Stainless steel is an alloy formed of iron and chromium. This alloy creates an inert surface which protects the underlying metal from corrosion. Not only does this make your favorite stainless steel cookware dishwasher-safe, it also renders it virtually rust-proof.
Handwashing is especially important with these items as the heat of the dishwasher can (and likely would) damage the ever-important seals on the cup, allowing air into that precious insulated airspace and compromising its ability to keep that which is cool, cool or hot, hot.
