I have this T-Fal non stick pot, and really I don't have any use for the non stick coating. I'm wondering if there's any harm in washing it in the dishwasher aside from the non-stick coating wearing off. In particular I am wondering about food safety.

  • Hello Mike, the health effects of ingesting PTFE are not something we can discuss here, see cooking.stackexchange.com/help/on-topic. Instead of closing, I removed the part about health effects, as it is possible that it will have culinary effects. But if answers veer into health claims, they will have to be removed. – rumtscho Aug 22 '16 at 8:03
  • @rumtscho the help article you linked doesn't clearly indicate that health effects of this sort are off topic. The closest example of an off-topic question describes a health question about a specific food. And an on-topic bullet point notes cooking equipment questions. – Mike Eng Aug 22 '16 at 11:17
  • You have misunderstood it. Health effects of any sort are off topic, described as "general health [...] issue". This is one of the strictest rules here. We cannot evaluate whether what you are putting into your body deserves the label "healthy". – rumtscho Aug 22 '16 at 11:21
  • Please do not edit to turn this into a health question. If you do, we will have to close it. – rumtscho Aug 22 '16 at 11:24
  • How is a potential safety issue arising or not arising from continued use of damaged equipment not a food safety issue? – rackandboneman Aug 22 '16 at 16:51

According to this manual, it is actually dishwasher safe

It already looks like the coating has worn off significantly. Without making any health claims (as I don't know what the impact of ingesting particles of T-fal coating), I don't think the dishwasher is going to do more damage, or release any more coating, than your use of inappropriate non-stick utensils already has. ...maybe, just time for a new pot.

Most non-stick can survive dishwashers anyway. If it's already scratched the scratches might get bigger but not necessarily. Depending on the metal underneath, there's a chance of it starting to flake off. Once that happens, it's pretty much gone.

The downside of the coating coming off is that food sticks worse than it would to a pan that was bare metal to start with. This may have something to do with intermediate surface treatments, and isn't a problem if you're using it for just boiling things in water.
