The Instant Pot, that magical kitchen appliance promising perfectly cooked meals in record time, can sometimes… disappoint. One of the most common frustrations is when your Instant Pot simply refuses to reach pressure. You set everything up, hit start, and wait… and wait… only to be met with a lukewarm pot of food and a nagging feeling of culinary failure. But don’t despair! This comprehensive guide will walk you through the most common reasons why your Instant Pot isn’t pressurizing, offering detailed troubleshooting steps and expert tips to get your cooking back on track.
Understanding How the Instant Pot Works: A Quick Primer
Before diving into troubleshooting, it’s helpful to understand the basic mechanics of how an Instant Pot achieves pressure. The Instant Pot, at its core, is an electric pressure cooker. It works by trapping steam inside the pot, increasing the internal pressure and raising the boiling point of water. This higher boiling point allows food to cook much faster.
When you start an Instant Pot program, the heating element at the bottom of the pot begins to heat the liquid inside. As the liquid heats, it produces steam. This steam is trapped inside the pot by the sealing ring and the lid. As more steam is produced, the pressure inside the pot increases. Once the pressure reaches the set level for the chosen program, the float valve rises, sealing the pressure inside, and the cooking countdown begins.
If the pot cannot create and maintain this pressure, it will not reach the set pressure, and the timer will not start. The Instant Pot is designed with safety in mind, so it will automatically stop the cooking process if it senses a problem preventing the buildup of pressure.
Common Reasons for Pressure Problems: A Detailed Breakdown
Several factors can prevent your Instant Pot from reaching pressure. Let’s explore the most frequent culprits and how to address them.
The Sealing Ring: Your Pot’s First Line of Defense
The sealing ring, the silicone ring that sits inside the lid, is crucial for creating an airtight seal. If the seal is compromised, steam will escape, preventing the pot from reaching the necessary pressure.
Checking for Damage and Proper Placement:
Remove the sealing ring and inspect it carefully for any cracks, tears, or deformities. Even a small imperfection can disrupt the seal. Ensure the sealing ring is properly seated within the wire ring on the lid. It should fit snugly and evenly. If the ring seems loose, try stretching it slightly to restore its elasticity. Wash the sealing ring with soap and water after each use to remove food particles and grease that can interfere with the seal.
Addressing Odors and Replacing the Ring:
The sealing ring can absorb odors from the food cooked in the Instant Pot. If you frequently cook dishes with strong smells, such as chili or curry, consider having separate sealing rings for savory and sweet dishes. A lingering odor is also a sign that the sealing ring might be porous and needs replacing. A damaged sealing ring is the most common cause of the problem and typically an easy and cheap fix.
The Float Valve: Ensuring a Proper Seal
The float valve is the small, metal pin that pops up to indicate the pot has reached pressure. It plays a crucial role in sealing the lid.
Checking for Obstructions and Proper Movement:
Make sure the float valve can move freely. Food particles or debris can sometimes become lodged around the valve, preventing it from rising and sealing properly. To clean it, remove the valve (consult your Instant Pot manual for specific instructions) and wash it thoroughly with soap and water. Ensure the silicone gasket under the float valve is also clean and properly seated. The float valve should sit down when the pot is not under pressure, and pop up when it is under pressure.
Verifying Correct Assembly:
Ensure all parts of the float valve assembly are correctly installed and in the right order. Incorrect assembly can prevent the valve from sealing. Consult your Instant Pot manual for a diagram illustrating the correct assembly of the float valve.
The Lid: Ensuring a Snug Fit
A properly sealed lid is essential for pressure to build inside the pot.
Checking for Debris and Damage:
Inspect the rim of the Instant Pot liner and the edge of the lid for any food particles or debris that could prevent a tight seal. Even a small crumb can create a gap. Also, check the lid for any dents or damage that could compromise its ability to seal correctly.
Ensuring Correct Lid Alignment:
Make sure the lid is properly aligned and securely locked into place. The arrows on the lid and the base of the Instant Pot should line up correctly. Listen for the characteristic “click” that indicates the lid is securely locked. If the lid is not properly aligned, the Instant Pot will not pressurize.
Insufficient Liquid: The Steam Engine’s Fuel
The Instant Pot needs liquid to create steam and build pressure. Without enough liquid, the pot will not pressurize.
Understanding Minimum Liquid Requirements:
Most Instant Pot models require at least 1 cup (8 ounces) of liquid to function properly. Some recipes may require more, depending on the ingredients and the cooking time. Always refer to your Instant Pot manual and the specific recipe for the recommended amount of liquid.
Using the Right Type of Liquid:
Water, broth, and stock are all suitable liquids for the Instant Pot. Avoid using thick sauces or purees as the primary liquid, as they can scorch and prevent the pot from reaching pressure. If a recipe calls for a thick sauce, add it after the food has been cooked under pressure.
The Burn Error: A Sign of Trouble
The “Burn” error message indicates that food is sticking to the bottom of the pot and overheating. This can prevent the Instant Pot from reaching pressure.
Preventing Food from Sticking:
To prevent the “Burn” error, ensure there is enough liquid in the pot and avoid using thick sauces as the primary cooking liquid. Use the “Sauté” function with caution, as it can easily lead to food sticking to the bottom. Deglaze the pot after sautéing by adding liquid and scraping up any browned bits from the bottom before pressure cooking.
Using the Pot-in-Pot Method:
The pot-in-pot (PIP) method involves placing the food in a separate, oven-safe dish that sits on a trivet inside the Instant Pot. This method prevents food from directly contacting the bottom of the pot, reducing the risk of burning.
Food Volume: Too Much or Too Little
The amount of food in the Instant Pot can also affect its ability to pressurize.
Avoiding Overfilling:
Do not overfill the Instant Pot. Overfilling can prevent the pot from reaching pressure and can also be dangerous. Never fill the pot beyond the maximum fill line, which is typically marked inside the pot. When cooking foods that expand, such as rice or beans, fill the pot even less.
Addressing Insufficient Food Volume:
While overfilling is more common, sometimes too little food can also be a problem. If you’re cooking a very small amount of food, the Instant Pot may not be able to generate enough steam to reach pressure. In such cases, consider doubling the recipe or using a smaller Instant Pot model.
Instant Pot Settings and Program Selection
Selecting the wrong program or settings can also prevent the Instant Pot from reaching pressure.
Verifying the Correct Program:
Ensure you’ve selected the appropriate program for the food you’re cooking. Some programs, such as “Sauté” or “Yogurt,” are not designed to build pressure. Always use a pressure cooking program like “Manual/Pressure Cook,” “Meat/Stew,” or “Bean/Chili” to achieve pressure.
Adjusting Pressure Levels and Cooking Time:
Some Instant Pot models allow you to adjust the pressure level. Make sure the pressure level is set appropriately for the recipe. If the cooking time is too short, the pot may not have enough time to reach pressure.
Power Issues and Malfunctions
Sometimes, the problem isn’t with the Instant Pot itself, but with the power supply.
Checking the Power Cord and Outlet:
Ensure the power cord is securely plugged into both the Instant Pot and the electrical outlet. Try a different outlet to rule out a faulty outlet. If the power cord is damaged, it needs to be replaced.
Identifying Potential Malfunctions:
If you’ve tried all the troubleshooting steps and the Instant Pot still isn’t working, there may be an internal malfunction. In this case, contact the manufacturer or a qualified appliance repair technician for assistance.

Why is my Instant Pot showing the “Burn” message, and could this prevent it from reaching pressure?
The “Burn” message on your Instant Pot indicates that the food at the bottom of the inner pot is overheating and potentially scorching. This often happens when there isn’t enough liquid, the liquid is too thick, or there’s food stuck to the bottom. The Instant Pot’s safety mechanisms will often halt the pressure-building process to prevent further burning.
If the “Burn” message appears frequently, it will definitely prevent the pot from reaching pressure. The Instant Pot will repeatedly try to build pressure, detect the burn, and stop, ultimately extending cooking time significantly or preventing cooking altogether. This is because the heating element is shutting down as a safety precaution, preventing it from achieving the necessary temperature for pressure.
I’ve made sure the lid is sealed, but the Instant Pot still won’t pressurize. What could be the issue?
While a properly sealed lid is crucial, other factors can still prevent pressurization. Check the silicone sealing ring for any cracks, tears, or deformities. A damaged sealing ring won’t create an airtight seal, allowing steam to escape and preventing the pressure from building up. Also, ensure the sealing ring is correctly positioned within the lid’s designated groove.
Another common cause is a malfunctioning or obstructed pressure release valve. Make sure the valve is set to the “Sealing” position and that it isn’t clogged with food debris. Even a tiny blockage can create a path for steam to escape, hindering pressure buildup. Periodically clean the valve to remove any residue.
How much liquid is actually needed for the Instant Pot to reach pressure?
The minimum amount of liquid required varies slightly depending on the Instant Pot model and the food being cooked, but generally, you need at least one cup (8 ounces) of liquid. This liquid is essential for creating the steam that generates pressure inside the pot. Without sufficient liquid, the heating element will struggle to produce enough steam.
It’s crucial to note that some recipes require more liquid than others, especially when cooking dense ingredients like beans or grains. Always refer to the recipe’s instructions for specific liquid requirements. Adding too little liquid not only prevents pressurization but can also lead to the dreaded “Burn” message.
Is it normal for steam to escape while the Instant Pot is coming to pressure?
Some minimal steam release is normal during the initial stages of pressurization, especially around the pressure release valve. This is because the valve needs to seat properly and the air inside the pot needs to be purged. However, excessive steam escaping, particularly from around the lid’s edge, indicates a problem.
If you observe significant steam escaping for an extended period, it suggests an issue with the sealing ring, the lid’s fit, or the pressure release valve. Monitor the steam carefully. If it continues unabated after a few minutes, there’s likely a problem preventing a proper seal, and the Instant Pot might not reach pressure.
Could the type of food I’m cooking affect the Instant Pot’s ability to reach pressure?
Yes, certain foods can indeed affect the Instant Pot’s pressurization process. Foods that release a lot of starch, like pasta or oatmeal, can thicken the cooking liquid excessively. This thick liquid can then splatter and clog the pressure release valve, preventing proper sealing and hindering pressure buildup.
Additionally, foods with a high sugar content can caramelize and burn easily on the bottom of the pot, triggering the “Burn” message and halting the pressurization process. When cooking these types of foods, it’s important to use sufficient liquid, deglaze the bottom of the pot thoroughly, and consider using the “Pot-in-Pot” (PIP) method.
I’ve checked everything mentioned, and the Instant Pot still won’t pressurize. What else can I try?
If you’ve verified the sealing ring, pressure release valve, liquid level, and food type, and the Instant Pot still fails to pressurize, there might be an issue with the heating element. A malfunctioning heating element won’t generate sufficient heat to create the necessary steam for pressure cooking.
Another possibility is a faulty pressure sensor. The pressure sensor monitors the internal pressure and signals the heating element to turn on or off. If the sensor is malfunctioning, it might not accurately detect the pressure, preventing the Instant Pot from reaching the required level. In either case, contacting Instant Pot support or a qualified appliance repair technician is recommended.
How do I clean the sealing ring to ensure it creates a good seal?
To properly clean the sealing ring, remove it from the Instant Pot lid after each use. Wash it thoroughly with warm, soapy water. Pay close attention to removing any food particles that may be trapped in the grooves of the ring.
After washing, rinse the sealing ring thoroughly with clean water and allow it to air dry completely before reinstalling it in the lid. Periodically, you can also soak the sealing ring in a mixture of water and vinegar to help remove stubborn odors and stains. Consider having multiple sealing rings, as they can absorb odors over time, and using different rings for different types of foods (e.g., savory vs. sweet).
