Why does my pot just say on?!? Once you program the Instant Pot to begin pressure cooking, the display panel of the Instant Pot will say On. It will remain On until the Instant Pot is pressurized. Once the float valve comes up, it may take a few minutes for the Instant Pot display to change from On to counting down the pressure cooking time. The instant lot will count down from the time you set it to. When the time is up, the pot will automatically turn over to keep warm and will display an L0:0
