To start pressure cooking, add liquid, lock the lid, turn the steam valve to Sealing, press the Pressure Cook or Manual button, and set your time.
Many new owners stare at the control panel and feel unsure. The buttons look different depending on the model, and the fear of doing it wrong is real. Getting the pot to actually pressurize involves a specific sequence of steps.
If you miss one detail, such as the valve position or the liquid minimum, the pot will not work. It might burn your food or just sit there heating up without ever counting down.
This guide breaks down exactly how to get your machine running safely. We cover every button press, the noises you will hear, and what the display shows while the machine builds pressure.
Understanding The Basic Buttons Before You Begin
You need to know which key triggers the standard cooking cycle. Instant Pot models use different labels for the exact same function. This causes confusion for people reading recipes that say “press Manual” when their pot does not have that button.
Pressure Cook vs. Manual — These are identical. Older models like the IP-DUO60 usually say “Manual.” Newer models like the Duo Nova or Pro say “Pressure Cook.” Both buttons tell the machine to heat up the heating element at the bottom until the internal pressure reaches a high level (usually 10.2 to 11.6 psi).
The +/- Keys or Dial — Once you hit the main button, you adjust the cook time immediately. On button-based models, you tap the plus or minus keys. On models like the Ultra or Pro, you spin a central dial and press it to confirm.
Pressure Level — Most recipes assume you are cooking at “High Pressure.” Some models allow you to toggle this to “Low.” You usually press the “Pressure Level” button to switch between them. If your model does not have this button (like the Lux), it likely cooks at High Pressure by default.
How To Start Pressure Cooker On Instant Pot
This section covers the standard operating procedure for almost any meal. Follow these steps in order to avoid the dreaded “Burn” notice or a lid that refuses to lock.
- Check the stainless steel liner — Make sure the inner pot is inside the base unit. Never pour ingredients directly into the black housing, as this will destroy the electronics.
- Add your ingredients and liquid — You must have at least 1 cup of thin liquid (water, broth, thin sauce) to generate steam. Without liquid, the sensor cannot build pressure.
- Inspect the sealing ring — Look at the silicone ring inside the lid. It should be seated continuously behind the metal rack. If it is loose or popped out, steam will leak from the sides.
- Lock the lid in place — Set the lid on the pot and turn it clockwise until you hear a chime or feel it click shut. The machine will not start the pressure cycle if the lid is open.
- Set the steam release valve — Locate the weighted valve on top. Turn it to the “Sealing” position. On some newer models like the Duo Nova, this happens automatically when you close the lid.
- Select your cooking program — Press “Pressure Cook” or “Manual.” The display will likely show a default time, such as 00:30.
- Adjust the time — Use the +/- buttons to set your desired cook time. This is the time the food cooks after pressure builds, not the total time.
- Wait a few seconds — Stop touching the buttons. After a brief pause, the pot will beep, and the display will verify the cycle has begun. It usually says “On.”
Visual Cues During The Startup Phase
New users often think the machine is broken immediately after setting the time. The screen displays “On,” but the timer does not count down. This is normal behavior.
The “On” message means the heating element is active. The water inside is boiling to create steam. You generally do not see the countdown timer until the float valve pops up and the internal sensor detects full pressure. This pre-heating stage takes anywhere from 5 to 20 minutes depending on how full the pot is.
The Essential Safety Checks Before Starting
Pressure cooking is safe if you respect the mechanics of the device. A few quick checks prevent the majority of kitchen accidents and messes. Do this every single time you cook.
Clear the anti-block shield — This is the small round metal cap inside the lid. Food particles can get stuck here, blocking steam from regulating correctly. Pop it off and rinse it if you cooked something frothy like oats or beans recently.
Check the float valve movement — The small metal pin (red or silver) next to the steam handle must move freely. If it is stuck with dried food, the lid might not lock, or the pot might not seal. Wiggle it with your finger to confirm it is loose.
Clean the rim of the base — Crumbs or rice grains often fall onto the rim of the plastic housing. If debris sits there, the lid creates a gap. This prevents the pot from reaching high pressure, and you will see steam escaping from the rim instead of the valve.
Setting The Time And Pressure Level
Recipes often give you a specific time and pressure setting. Entering these correctly determines if your meat comes out tender or tough. The interface changes slightly between models, but the logic remains the same.
Adjusting Time
The time on the display refers to “time under pressure.” If a recipe says “Cook for 20 minutes,” it means 20 minutes at high pressure. It does not include the time required to heat the water.
- Use the Plus/Minus keys — Tap repeatedly to change minutes. Holding the button down usually makes the numbers scroll faster.
- Check the minutes range — Most pots allow you to set pressure cooking time from 0 minutes up to 4 hours.
- “0 Minutes” function — You can set the pot to 0 minutes. This is useful for blanching vegetables. The pot builds pressure, then immediately stops and beeps, cooking the food gently with just the heat of pressurization.
Switching Pressure Levels
High pressure is the standard. It cooks food at roughly 240°F (115°C). Low pressure cooks at a lower temperature, around 229°F (110°C), and is better for delicate foods like eggs or fish.
To change this, press the “Pressure Level” button repeatedly. You will see indicators on the LCD screen switch between “Hi” and “Lo.” If your button layout does not have this option, your pot likely only supports High Pressure.
What Does The Display Mean While Cooking?
The digital display communicates exactly what the pot is doing. Learning this language stops you from guessing if the meal is actually cooking. Here is a breakdown of the standard display codes during a start sequence.
| Display Code | Meaning | Action Needed |
|---|---|---|
| On | Pre-heating. Water is boiling. | None. Wait for the float valve to rise. |
| Countdown (e.g., 00:15) | Pressure reached. Cooking has started. | None. The timer counts down by the minute. |
| L00:00 (counting up) | Keep Warm mode. Cycle finished. | Press Cancel to stop warming or release pressure. |
| Burn | Overheat detected at the bottom. | Press Cancel. Release steam. Check for scorched food. |
How To Stop Or Cancel The Cycle
Sometimes you enter the wrong time or realize you forgot an ingredient. Stopping the machine is simple, but opening it requires caution.
Press the Cancel button — Every model has a “Cancel” or “Keep Warm/Cancel” button. Pressing this immediately cuts power to the heating element. The display will go to “OFF.”
Do not force the lid — Even if you turned the machine off, high pressure remains inside. The lid is locked mechanically by the float valve. You cannot open it until you release the pressure.
Release the steam — If you just started and there is no pressure yet, the lid opens easily. If the pot was pressurized, turn the valve to “Venting” to release the steam quickly before opening. Keep your hand away from the steam jet.
Troubleshooting Common Startup Issues
You followed the steps on how to start pressure cooker on Instant Pot, but something went wrong. These are the most frequent barriers that stop a cycle from starting.
Steam Leaking From The Sides
If you hear a loud hissing sound coming from the rim of the lid rather than the valve, the seal is bad. The pot will never reach pressure this way. Press Cancel immediately. Open the lid and check the silicone ring. It might be wet, slipping, or damaged. Reseat it and try again.
Timer Never Starts
If the display stays on “On” for more than 20 minutes, you likely have a sealing issue or not enough liquid. Without enough steam, the sensor never trips. Check that the valve is truly in the Sealing position. If it is set to Venting, you are just boiling away your liquid.
Lid Won’t Lock
The locking mechanism requires the float valve to be down. If the valve is stuck in the up position, the locking pin hits it. Push the valve down gently with a utensil. Also, check that the sealing ring isn’t bunched up, preventing the lid from rotating.
Using Preset Buttons vs. Manual Control
Your Instant Pot panel is full of buttons like “Meat/Stew,” “Soup/Broth,” or “Rice.” Users often ask if they must use these specific buttons for specific foods.
They are just timers — Most of these buttons are simply presets for time and pressure level. For example, “Soup” might default to 30 minutes at High Pressure. You can achieve the exact same result by pressing Manual/Pressure Cook and setting the time to 30 minutes.
Exceptions to the rule — A few buttons do have special programming. “Rice” on some models uses low pressure automatically. “Yogurt” does not use pressure at all; it maintains a specific incubation temperature. For almost everything else, the Manual button is the most reliable way to cook because you control the variables.
The Cool Down Phase
Once the timer hits zero, the machine beeps. It does not turn off completely. It enters “Keep Warm” mode. The display changes to start counting up (L0:01, L0:02). This tells you how long the food has been sitting there since the cook cycle ended.
Natural Release — If you do nothing, the pot cools down slowly on its own. This takes 10 to 40 minutes. This is best for meats and soups to keep them tender and prevent foaming.
Quick Release — If you turn the valve to Venting immediately, steam shoots out. This stops the cooking instantly. Use this for vegetables or pasta so they do not get mushy.
Cleaning The Lid For Next Time
A successful start depends on a clean machine. The lid contains the most important safety mechanisms. After every cook, you should wash the silicone ring. It absorbs odors easily.
Remove the steam release handle and wash it. Run water through the steam pipe to clear any blockages. If the pipe is clogged, the pot cannot regulate pressure, which may prevent it from starting correctly the next time you use it.

➤ Minimum liquid requirement is typically 1 cup of water or thin broth.
➤ The steam valve must point to “Sealing,” not “Venting,” to build pressure.
➤ “Pressure Cook” and “Manual” buttons perform the exact same function.
➤ The timer only counts down after the pot pressurizes, not immediately.
➤ Inspect the silicone sealing ring for gaps before every single use.
Frequently Asked Questions
Can I use the Instant Pot without water?
No, standard pressure cooking requires thin liquid to create steam. If you use thick sauces or no liquid, the pot will overheat and trigger a burn error. However, you can use the Sauté function without water since it does not use pressure.
Why is steam coming out of the valve while cooking?
A small amount of steam escaping as the pot heats up is normal. However, once the float valve pops up, the steam should stop. If steam continues to hiss steadily from the valve during the cook cycle, verify the handle is fully turned to the Sealing position.
Does the timer count up or down?
During the actual pressure cooking cycle, the timer counts down to zero. Once the cooking is finished and the pot switches to Keep Warm mode, the timer starts counting up (shown as L0:00) to indicate how long the food has been sitting.
What happens if I forget to put the valve to Sealing?
The liquid inside will boil away because the steam is escaping freely. The pot will likely never reach high pressure, and the countdown timer will not start. Eventually, the liquid will evaporate completely, leading to scorched food or a safety shut-off.
Can I open the lid while it says On?
You can only open the lid if the pot is not pressurized. If the float valve is down, you can open it. If the float valve is up, there is pressure inside. You must press Cancel and turn the valve to Venting to release pressure before the lid will unlock.
Wrapping It Up – How To Start Pressure Cooker On Instant Pot
Learning how to start pressure cooker on Instant Pot models is the first step toward faster meal prep. The process is always the same: add liquid, seal the system, and choose your time. The buttons might seem intimidating, but they are just controls for a heater and a timer.
Trust the display to tell you the status. Remember that “On” means it is working hard to build heat, and the numbers mean you are cruising toward a finished meal. Keep the rim clean, watch your sealing ring, and you will get consistent results every time you lock that lid.
