Ovens don’t have a bunch of high pressure water sprayers in them. They just leak hot air at worst.
‘Just hot air’ is a bit of an understatement. Mine goes to 500°C during a cleaning cycle. It physically locks the door so you can’t open it when it does this. My dishwasher I can open at any time.
Fun fact you can hack a self-cleaning oven to use the hellfire temperature of 500 ° F to make good ass thin crust pizza!
you have to figure out how to bypass the door lock, use a pizza stone, and put the pizza as high up in the oven as possible. but you can get a damn good thin crust pizza with enough creative engineering and some experimentation.
recommended to try this project in winter as it dumps loads of heat in the house lol
