If cook time begins on the Instant Pot begins but the float valve has NOT popped up, the Instant Pot is not sealed.
Thereof, how do you set pressure release to seal Instant Pot?
You can either release the pressure immediately by doing a quick release (as we mentioned above) or let the Instant Pot complete a natural release on it’s own. Give it about 10 minutes and then push the vent valve before opening the lid to ensure there is no more pressure in the pot.
Similarly, should Instant Pot valve be up or down? Don’t open the lid until the float valve is down i.e. the Instant Pot is depressurized. Keep hands and face away from the steam release mechanism. Don’t obstruct the steam release handle when pressure is being released. When quick-releasing frothy foods such as applesauce, oatmeal, pasta, etc.
