I would recommend that you don't... even though dishwasher detergents are less harsh than they once were, aluminum will still get dull and discoloured.  I have a beautiful set of Club Aluminum (turquoise, natch) and I won't put them in even one of the short-cycle dishwashers.  Hubby put a mint Presto pressure cooker in the Maytag in St-Lib once and that was all it took to mess it up but good!

I wouldn't, but I always hear aluminum mentioned as either a "no no" or "very problematic". I personally might gamble with a well worn pot of no value, especially if I were feeling lazy that day...but something like this that's in mint condition would not see a dishwasher, ever.

Stuff cooks really well and is easy to clean. SOS pads work great. I recollect an American aunt with Club cookware who sprayed the inside with PAM before cooking - it really helped on clean up.
