Why is my Ninja Electric Pressure Cooker taking so long to come to pressure?
- D
  Dennis BartlettAug 19, 2025
  If your Ninja Electric Pressure Cooker is taking longer than expected to reach pressure, ensure the silicone ring is correctly installed and flush against the lid. You should be able to lightly tug and rotate the ring if it's properly seated. Also, verify that the pressure lid is fully locked and the pressure release valve is in the SEAL position when pressure cooking.

  If your Ninja Electric Pressure Cooker is hissing but not reaching pressure, make sure the pressure release valve is turned to the SEAL position. Also, press down on the silicone ring to ensure it is fully inserted and lies flat under the ring rack.

  As a safety measure, the pressure lid on your Ninja Electric Pressure Cooker will remain locked until the unit is fully depressurized. To release the pressure, turn the pressure release valve to the VENT position to quickly release the pressurized steam. Be aware that a quick burst of steam will come out of the valve.

Why is the time counting down so slowly on my Ninja Electric Pressure Cooker?

  The time may be counting down slowly on your Ninja Electric Pressure Cooker because you might have set hours instead of minutes. When setting the time, the display shows HH:MM, and the time increases/decreases in minute increments.
