Why is my unit taking so long to come to pressure? How long does it take to come to pressure?

Cooking times may vary based on the selected temperature, current temperature of the cooking pot, and temperature or quantity of the ingredients.Check to make sure your 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.

Why is the time counting down so slowly?

You may have set hours rather than minutes. When setting time, the display will show HH:MM and the time will increase/decrease in minute increments.

How can I tell when the unit is pressurising?

The rotating lights will display on the screen to indicate the unit is building pressure. Lights are rotating on the display screen when using the Pressure or Steam function.This indicates the unit is building pressure or preheating when using STEAM or PRESSURE. When the unit has finished building pressure, your set cook time will begin counting down.

There is a lot of steam coming from my unit when using the Steam function.

It’s normal for steam to release through the pressure release valve during cooking. Leave the pressure release valve in the VENT position for Steam, Slow Cook, and Sear/Sauté.

Why can’t I take the pressure lid off?

As a safety feature, the pressure lid will not unlock until the unit is completely depressurised. Turn the pressure release valve to the VENT position to quick release the pressurised steam. A quick burst of steam will spurt out of the pressure release valve. When the steam is completely released, the unit will be ready to open. Turn the pressure lid anticlockwise, then lift it up and away from you

Is the pressure release valve supposed to be loose?

Yes. The pressure release valve’s loose fit is intentional; it enables a quick and easy transition between SEAL and VENT and helps regulate pressure by releasing small amounts of steam during cooking to ensure great results. Please make sure it is turned as far as possible toward the SEAL position when pressure cooking and as far as possible toward the VENT position when quick releasing.

The unit is hissing and not reaching pressure.

Make sure the pressure release valve is turned to the SEAL position. If you’ve done this and still hear a loud hissing noise, it may indicate your Silicone seal is not fully in place.

Press START/STOP to stop cooking, VENT as necessary, and remove the pressure lid. Press down on the Silicone ring, ensuring it is fully inserted and lies flat under the ring rack. Once fully installed, you should be able to tug lightly on the ring to rotate it.

The unit is counting up rather than down.

The cooking cycle is complete and the unit is in Keep Warm mode.

How long does the unit take to depressurise?

Quick release is about 2 minutes or less. Natural release can take up to 20 minutes or more, depending on the type of food and/or the amount of liquid and food in the pot.
