I don’t care about the non stick property of a non stick pot. Is there any harm in washing it in a dishwasher

How old is the piece? Is the piece actually rated for the dishwasher?

I don't know what the latest stuff is rated for, but I've always been under the impression that non-stick coatings are pretty fragile, and that while they are better today than ever before, I just assume that I'm not supposed to dishwasher them.

Assuming that it is rated for the dishwasher, this seems odd, unless the pan was a bit old, and the coating had degraded somewhat, allowing it to fail in this way.

I REALLY think you should contact the manufacturer about this - they should have some clue what happened, and should be able to give you hints on prevention.

I tried seasoning an aluminium kawali and was pretty successful doing this. I cleaned it very well and then layered it with a bit of oil (use peanut or canola) and then baked it outside on the bbq (or oven) for 30mins each time and then reapplying oil when it’s cooled down to touch. Important and ensure your kawali is upside down when baking and remove any handles. I repeated these steps 5 times ( see pics attached for result). Before using the wok properly, I sacrificed onions and ginger and burnt it for seasoning and then did the same thing with chicken pieces. To clean I used warm water, wipe it paper towel and dry it on stove top to fully dry the kawali. I then, apply some oil on it before storing on paper bag until next use.
