heat deformed oven outer shell?

I think you are having trouble with my words.

Yes.

Correct. I’m having trouble with your words and logic. You saw the pan in the manual being used for descaling and assume it’s a descaling pan. There isn’t enough there to make that claim yet you stand firm that it’s a pan intended for descaling only. It’s flawed logic. And you speak condescendingly affirming that it’s as you interpret it and that it’s fact. You rub me the wrong way brah. I’m not the only one in here frustrated right now.

I think you are mistaken.
