The Instant Pot has revolutionized home cooking, offering a convenient, multi-functional solution for preparing meals quickly and efficiently. However, despite its many benefits, reports of Instant Pots “exploding” or malfunctioning have sparked concern among users. While such incidents are rare, understanding what causes an Instant Pot to malfunction is essential for ensuring safe and stress-free cooking. In this article, we’ll explore the science behind pressure cooker function, the potential reasons for explosions or dangerous incidents, and how to use your Instant Pot safely.
How Does an Instant Pot Work?
Before diving into the reasons an Instant Pot might malfunction, it’s important to understand how it works. The Instant Pot is a modern electric pressure cooker that uses heat and pressure to cook food faster than traditional methods. It has several built-in safety features, including pressure sensors, overheat protection, and a locking lid mechanism to prevent premature opening during a cooking cycle.
Key Components of an Instant Pot
- Inner Pot – Usually made of stainless steel or ceramic-coated material, this is the container where food is placed.
- Lid with Steam Release Valve – Designed to regulate pressure, the lid has a valve that can be turned to vent steam manually.
- Float Valve – This mechanical indicator rises when pressure builds up inside, locking the lid to prevent opening until it’s safe.
- Pressure Sensors (CPU) – These detect internal pressure levels and maintain safe limits by controlling heat output.
- Safety Mechanisms – Instant Pots come equipped with over 10 different safety features, including anti-blockage vents and automatic shut-off systems.
These components work in unison to maintain safe pressure levels and ensure a secure cooking environment. However, when something goes wrong, the risk of an explosion or steam burst can occur.
What Does “Exploding” Really Mean?
When people say their Instant Pot exploded, they often refer to sudden bursts of steam, food erupting through the valve, or, in rare cases, a lid failure that compromises the seal and causes pressure to release rapidly. Actual explosions involving structural failure of the pot are exceedingly rare, especially with modern Instant Pots that are equipped with advanced safety features.
Common Misinterpretations of “Explosions”
Some scenarios that feel like explosions include:
- Steam Burst – When the steam valve is suddenly opened, hot steam can release quickly.
- Food Eruption – Using the quick release too early with foods like soup or beans can cause them to foam rapidly and eject from the pot.
- Lid Failure – In older or faulty models, the lid seal or locking mechanism may fail, leading to pressure leaks.
Primary Causes of Instant Pot Malfunctions or Explosions
While Instant Pot explosions are rare, there are specific issues and misuse patterns that increase the risk. Below, we delve into the most common causes that can lead to dangerous pressure releases or accidents.
1. Blocked Steam Release Valve
One of the most common reasons for pressure-related incidents is a blocked steam release valve. When food particles, thick sauces, or grains clog the valve, pressure cannot vent properly, potentially leading to dangerously high pressure buildup within the pot.
How to Prevent This:
- Close the steam release valve only during cooking. Open it manually when releasing steam after the cook cycle.
- Use a strainer or trivet to keep food away from the venting system.
- Check the vent regularly for food residue buildup and clean it after each use.
2. Improper Lid Sealing or Opening
The Instant Pot lid must be properly sealed before pressure can build up. However, one of the most dangerous misuses occurs when users try to open the lid before the internal pressure has fully dissipated.
Key Points:
- The float valve must be down before opening the lid. If it’s up, pressure is still inside.
- Never force the lid open; doing so can result in a rapid release of accumulated steam and cooking liquid.
- The lid locking mechanism is mechanical, not electronic. Malfunctioning or worn locking arms can increase risk.
3. Overfilling the Instant Pot
A frequently overlooked safety rule is the importance of not overfilling the Instant Pot. When too much food or liquid is added, there’s a greater chance of sudden foaming and pressure buildup that can overwhelm the vent system.
Safety Guidelines:
- Follow the 2/3 max fill rule for most foods.
- Use the “fill line” etched onto the inner pot as a guide.
- For foods that foam (like beans or rice), ensure the pot is filled no more than halfway.
4. Faulty or Aging Sealing Ring
The sealing ring, typically made of silicone, is a crucial component of the Instant Pot. If it becomes old, cracked, or improperly seated, it can fail to maintain pressure, leading to excess buildup or uncontrolled release.
When to Replace the Sealing Ring:
| Condition | Action |
|---|---|
| Cracking or hardening | Replace immediately |
| Unpleasant odors that won’t fade | Replace for hygiene and sealing integrity |
| Improper fit or alignment | Adjust or replace for safe unit operation |
5. Defective Pressure Sensors
While electric pressure cookers are built with internal CPUs to regulate pressure levels, hardware defects or manufacturing flaws can result in sensor malfunctions. These may lead to overpressurization or incorrect pressure readings.
Signs of Pressure Sensor Issues:
- Failure to respond to pressure adjustments
- Slow or erratic pressure buildup
- Unusual beeping or error messages
6. Using Incorrect Accessories or Aftermarket Parts
Adding third-party or non-Instant Pot approved attachments can interfere with safe operation. This includes after-market lids or pressure release valves that don’t match the original specifications.
Safe Accessory Use Tips:
- Stick to factory-recommended accessories.
- Verify compatibility of third-party items with your specific Instant Pot model.
- Avoid modifying or altering any part of the pressure system.
7. Leaving the Pot Unattended
While the idea of “set it and forget it” cooking is appealing, leaving a pressure cooker running without monitoring can increase the risk of unexpected malfunctions. In rare cases, the internal mechanisms can fail, leading to pressure issues or overheating.
Real Case Studies and Consumer Reports
Consumer watchdog organizations and product safety boards have documented cases involving electric pressure cookers, including the Instant Pot. While the majority of these incidents involve user error or mismanagement, a small percentage have been linked to factory defects or aging units.
Notable Examples:
- A 2017 report noted that some early models of the Instant Pot had issues with seal failure, leading to small steam bursts.
- There have been rare cases of faulty pressure regulators causing overheating and steam release accidents.
- Over time, older non-certified pressure cooker designs have had incidents similar to Instant Pot malfunctions reported under different brands.
Legal Recalls and Product Safety Warnings
As of the latest data, no major recalls have targeted the Instant Pot due to explosions. However, Instant Pot has issued minor advisories for replacement of sealing rings or latch components on certain older models. Always check with the manufacturer and register your product for safety alerts.
Built-In Safety Mechanisms: What Instant Pot Does to Prevent Explosions
Instant Pot has been specifically designed with advanced safety protocols that far exceed older stovetop pressure cooker technology. These mechanisms minimize the risk of explosions and uncontrolled pressure release.

By adhering to manufacturer guidelines, maintaining the appliance, and thoroughly understanding how pressure cooking works, users can enjoy the convenience and versatility of the Instant Pot without worry. With the right education and safety-conscious habits, the modern pressure cooker remains a powerful ally in the kitchen—not a hazard.
What causes an Instant Pot to explode?
One of the most common reasons an Instant Pot may explode is due to a failure in the pressure release system. If the steam cannot escape properly because the pressure valve is blocked or improperly positioned, pressure can build up beyond safe levels, leading to a sudden and dangerous release of steam and contents. Food debris, thick sauces, or overfilling the pot can contribute to this blockage, increasing the risk of a malfunction.
Additionally, mechanical failure or user error can also contribute to explosions. Faulty safety mechanisms such as a damaged lid, worn-out sealing ring, or issues with the internal sensors can prevent the Instant Pot from functioning as intended. Users who ignore manufacturer guidelines—for example, by using modified parts or disregarding recommended fill levels—may also unknowingly create hazardous situations. These factors combined can cause the Instant Pot to behave unpredictably, leading to a serious accident.
How do safety features prevent Instant Pot explosions?
Modern Instant Pots are equipped with multiple built-in safety features designed to prevent dangerous accidents. These include mechanisms such as overpressure protection, lid lock systems, anti-blockage vents, and automatic shut-off functions. These features work together to regulate internal pressure, ensuring the lid cannot be opened while the pot is pressurized and that steam is safely vented throughout the cooking process.
If any irregularity is detected—such as the pressure reaching unsafe levels—the Instant Pot will typically shut off automatically to prevent further buildup. These safety systems drastically reduce the risk of explosions, but they are not foolproof. Users must still follow safety guidelines and regularly inspect their unit for wear or damage. Only through proper use and maintenance can these safety features function as intended.
What role does overfilling play in Instant Pot accidents?
Overfilling an Instant Pot is one of the most preventable mistakes that can lead to a dangerous situation. When the inner pot is filled beyond the recommended maximum line (usually two-thirds full for most foods and half full for foods that expand, such as beans or rice), there may not be enough space for steam to circulate properly. This can cause pressure to build up too quickly, or the food can clog the vent, both of which are risk factors for an accident.
Moreover, overfilled contents can foam or expand during cooking and be pushed into the pressure release valve or sealing ring. Once a valve is blocked, the pressure has nowhere to escape, increasing the potential for a steam burst or lid malfunction. It’s essential to respect fill limits and use the appropriate inner pot size if using the pot-in-pot method, especially when cooking foods that foam easily. Practicing awareness of how much you load into the pot is key to preventing such incidents.
Why is proper venting important in avoiding pressure cooker mishaps?
Proper venting is critical for maintaining control over the internal pressure of the Instant Pot and ensuring a safe cooking process. The steam release valve and anti-blockage features are designed to allow continuous pressure adjustments. If the vent is closed when it should be open or becomes clogged, pressure can build up without an exit path, increasing the risk of a malfunction. This is especially dangerous during the natural release stage after cooking when users might mistakenly believe the pressure is gone when it’s still building inside.
To avoid such dangers, users should always ensure the steam release valve is in the correct position (venting or sealing) based on the recipe and cooking phase. After cooking, allowing the pressure to drop naturally (or doing a quick release as instructed) ensures the pressure doesn’t escape suddenly and uncontrollably. Educating oneself on how to safely operate these vents is essential to prevent accidents while using a pressure cooker.
How important is regular maintenance in preventing Instant Pot explosions?
Routine maintenance and part inspections are essential for ensuring long-term safety and functionality of your Instant Pot. Components like the sealing ring, lid, and steam release valve degrade over time due to wear and exposure to heat. A worn or misshapen sealing ring might not create a tight enough seal to regulate pressure, while a cracked lid could compromise the locking mechanism—both potentially leading to dangerous situations.
Common signs of wear include discoloration, stiffness, or warping in the sealing ring and residue buildup around the valve. Users should periodically clean all parts, replace them if they show signs of damage, and avoid using off-brand components that might not fit or function properly. Proper maintenance not only lengthens the life of the appliance but significantly reduces the risk of failure or improper pressure control.
Can using modified parts lead to Instant Pot explosions?
Using non-original or modified parts with an Instant Pot, such as third-party sealing rings, lids, or pressure valves, can be risky. While some users seek alternatives for convenience or cost savings, these parts may not be compatible with the appliance’s pressure control mechanisms. For instance, a third-party sealing ring might not fit properly around the steam release valve, which could lead to a delay in pressure regulation or improper sealing, both of which increase the likelihood of an accident.
Furthermore, modified lids or valves may lack the safety precision of the original equipment, and they might bypass the built-in fail-safes designed by the manufacturer. Always ensure that replacement parts are made by the original manufacturer or verified as compatible by experts. Avoid modifications that override the appliance’s safety systems, even if they seem practical for specific cooking techniques. Using unverified or non-standard parts is unnecessary and potentially dangerous.
How can users avoid accidents when using their Instant Pot?
To avoid accidents when using an Instant Pot, users should start by reading and following the manufacturer’s instructions carefully. Understanding how the device functions with regard to pressure settings, release valves, and heat distribution ensures users make informed choices when cooking. This includes learning how to use both steam release options safely and being aware of signs that something has gone wrong, such as unusual noises or pressure build-up.
In practice, users should also adhere to fill guidelines, ensure the vent is positioned correctly, and inspect all components regularly for wear or damage. Educating oneself by consulting the Instant Pot manual and watching step-by-step tutorials can further clarify best practices. Staying vigilant during the cooking process and avoiding distractions, especially when the pot is actively pressurized, is crucial in maintaining user safety and preventing potential accidents.
