If your instant pot does not have the option of letting you get high pressure, you will need to set it yourself with the manual or pressure cook button. High pressure is a default setting for both these buttons. Once you have pressed either of them, check the display on the pot to make sure it says high. In case it doesn’t, press the same button again until it shows high. The plus and minus buttons will allow you to set your cooking time and let the pot work its magic.
