As pressure builds in the unit, the control panel will display moving lights and the word PRE. The timer will begin counting down once the unit reaches pressure.
The time to build pressure can take up to 20 minutes. The amount of time varies based on the selected pressure, current temperature of the cooking pot, and temperature and quantity of the ingredients.
Check to make sure the silicone ring is fully seated and flush against the lid. If installed
correctly, you should be able to tug lightly on the ring to rotate it.
Check that the pressure lid is fully locked and the pressure release valve is in the SEAL
position when pressure cooking.
If you want to shorten the time it takes the unit to build pressure, use hot liquid.
