Sounds like the knife fell out of the rack onto the heating element.
Personally, I don't even put my knives in the dishwasher. Too much chance for them to be damaged or damage something else.
Edit: I guess redditors have never seen a fucking ceramic knife before? Or am I missing something here?
Could also just be a painted blade knife, which are also common.


You're aware no child left behind was literally that, and it's a big reason for schools declining as they are right now, right? Because the standards it set were poorly thought out, and the execution of said standards was also terrible. And that was when the US government was still even mildly coherent.
The educators - the people who actually gave enough of a fuck to go through years of college and take a dirt poor job because they believed in teaching - should be setting the curriculum. Not some bullshitting politician on the hill.
