Last step is to make sure the Instant Pot is depressurized before opening the pot. We will be using NPR - Natural Pressure Release method. After the cooking cycle of the Instant Pot Spaghetti is finished, there are a couple of things that need to be done prior to opening the lid.
First, wait until the Floating Valve (metal pin) completely drops before opening the lid (about 10 minutes).
Second, turn the Venting Knob from "Sealing" to "Venting" to ensure all the pressure is released before opening the lid (about 5-10 minutes).
Third, open the lid.
