OP300 FAQS
A rotating light will appear on the digital display to indicate the unit is building pressure. 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 the temperature and quantity of the ingredients.
If you want to shorten the time it takes the unit to build pressure, use hot liquid.
No, the crisping lid does not detach from the unit.
Yes. For best results when making a smoothie or drink, select the EXTRACT button and let the program run until it completes.
Pressure: Cooks food quickly (70% faster as compared to slow cooking) while maintaining tenderness.
Steam: Use the steam function to gently cook delicate foods at a high temperature.
Slow Cook: Cooks food at a lower temperature for longer periods of time.

To set the cook time, use the Time up and down arrows on the right side of the digital display (the clock will display HH:MM). You can change the time at any point during cooking.
To Quick Release pressure, turn the pressure release valve to the VENT position by using the tab on the end. Be sure to keep your face away from the release valve, as a quick burst of steam will spurt out of the pressure release valve. When all the steam is completely released, the float valve will drop down and the unit will be ready to open. Do not place your hand over the valve because hot steam will release immediately.
To Natural Release pressure, do not turn the pressure release valve to VENT. Instead, when cook time is complete, wait for the unit to naturally release the pressure on its own. This can take up to 20 minutes, depending on the amount of liquid and food in the pot. During this time, the unit will switch to Keep Warm mode and the clock will start counting up. When Natural Release is complete, the float valve will drop down and the unit will be ready to open.
To lock the pressure lid in place, align the arrow on the lid with the arrow on the front of the unit. Then turn the lid clockwise until it stops. There will be an audible chime when the lid is properly installed, and the top row of lights on the display screen illuminte.
As the unit pressurizes, the lid will lock as a safety measure, and it will not unlock until all pressure is released. If the red float valve on the lid is raised up, this indicates the unit is pressurized.
Preheating is recommended for best results. To preheat, simply add 5 minutes to the cook time and allow the unit to come to temperature before adding ingredients.
To install the condensation collector, slide it into the slot on the back of the cooker base. To remove it, slide it out and hand-wash it after each use in warm, soapy water.
No, once the unit has started pressure cooking, we do not recommend moving it.
To cancel, press START/STOP or the Power button.
Yes, you can use aluminum foil.
You can use oven-safe dishes or pans in the unit. However, you should NOT pressure cook using glass dishes.
Product care & maintenance
The unit should be cleaned thoroughly after every use. Unplug the unit before cleaning.
To clean the cooker base and control panel, wipe them down with a clean, damp cloth. Never immerse the cooker base in water or any other liquid, nor clean the cooker base in the dishwasher.
The cooking pot, reversible rack, Cook & Crisp™ Basket, and silicone ring are all dishwasher safe. To clean the pressure lid, hand-wash in warm, soapy water.
To clean the crisping lid, wipe it down with a damp cloth or paper towel after the heat shield has cooled.
Air-dry all parts after cleaning. If there is food residue stuck on the cooking pot or reversible rack, place the pot or rack in the sink, fill it with warm water, and allow to soak before cleaning.
Always use a non-abrasive sponge or cleaning tool when washing your unit.
To clean the silicone ring:
Remove the silicone ring by pulling it outward, section by section, from the silicone ring rack.
Wash the ring in warm, soapy water or on the top rack of the dishwasher to help remove any odor. To avoid odor, we recommend cleaning the ring after every use. It is common for the ring to retain the smell of acidic foods, even after cleaning.
The silicone ring can be installed with either side facing up. To reinstall it, press it down into the rack section by section.
Never pull out the ring with excessive force, as this may deform the ring or the rack, affecting the pressure-sealing function. If the rings has cracks, cuts, or any other form of damage, it should be replaced immediately.
Troubleshooting
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.
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.
The rotating lights will display on the screen to indicate the unit is building pressure.
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.
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.
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.
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.
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 cooking cycle is complete and the unit is in Keep Warm mode.
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.
Cooking pot is not inside the cooker base. Cooking pot is required for all functions.
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 and in the close position.
The crisping lid is open and needs to be closed for the selected function to start.
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.
The water level is too low. Add more water to the unit for the function to continue.
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.
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.
