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 pressurizing? 

•   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 

depressurized. To release pressure, turn the pressure release valve to the VENT position 

to quick release the pressurized 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. To unlock the pressure lid, turn it counterclockwise. Lift the lid at an angle to prevent 

splatter. Do not lift the lid straight up. 

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 depressurize?

•   The time it takes to release pressure depends on the quantity of food in the system and 

can vary from recipe to recipe. Always ensure the float valve has dropped before trying 

to remove the lid. If the system is taking longer than normal to depressurize please 

unplug the unit and wait until the float valve drops before interacting with the product.

TROUBLESHOOTING GUIDE

“POT” error message appears on display screen .

•   Cooking pot is not inside the cooker base. Cooking pot is required for all functions.

“LID” error message appears on display screen and lid icon flashes .

•   The incorrect lid is installed for your desired cooking function. Place the pressure lid  

on the unit if you want to use the Pressure, Slow Cook, Steam, Sear/Sauté, or Keep  

Warm functions. Make sure the lid is in the closed position.

“SHUT” error message appears on display screen .

•  The crisping lid is open and needs to be closed for the selected function to start.

“VENT” error message appears on display screen .

•   When set to Slow Cook or Sear/Sauté, and the unit senses pressure building up, this 

message indicates the pressure release valve is in the SEAL position. 

•   Turn the pressure release valve to the VENT position and leave it there for the remainder 

of the cooking function.

•   If you do not turn the pressure release valve to the VENT position within 5 minutes, the 

program will cancel and the unit will shut off.

“WATR” error message appears on display screen when using the Steam function .

•   The water level is too low. Add more water to the unit for the function to continue.

“WATR” error message appears on display screen when using the Pressure function .

•   Add more liquid to the cooking pot before restarting the pressure cook cycle.
•   Make sure the pressure release valve is in the SEAL position. 
•   Make sure the silicone ring is installed correctly.

“HOT” error message appears on display screen .

•   This indicates the unit has overheated. Let the unit cool down.
•   Once unit has cooled down, ensure there is no food caked on the bottom of the pot  

and there is enough liquid in the pot for the recipe you are preparing.

“ERR” message appears .

•   The unit is not functioning properly. Please contact Customer Service at 1-877-646-5288.
