Common Reasons for Pressure Cooker Malfunction
Pressure cookers have gained widespread popularity for their ability to cook meals quickly under high pressure.
However, sometimes issues can arise where a pressure cooker fails to build the required pressure.
This malfunction can be due to several factors ranging from the pressure release handle’s incorrect position to a damaged sealing ring.
Understanding these common causes can help diagnose and resolve the problem, ensuring the pressure cooker is safe and efficient to use.
Pressure release handle position
The position of the pressure release handle, commonly referred to as the steam release handle or pressure valve, is crucial in pressure building.
For an Instant Pot, the handle must be turned to the SEALING position to allow the cooker to build pressure.
Conversely, moving it to the Venting position releases the pressure inside.
If the handle is not in the correct position, the internal pressure cannot be maintained, leading to failed pressure cooking sessions.
It is important to ensure that the steam release handle is in the SEALING position and functioning correctly to resolve this issue.
Sealing ring issues
The sealing ring, also known as the safety gasket, plays a vital role in creating an airtight environment within the pressure cooker.
If this ring is damaged, incorrectly placed, dirty, or has expanded due to heat exposure and not returned to its original size, it may prevent the unit from achieving a proper seal.
Regular inspection, cleaning with warm water and soap, and replacement when necessary are essential maintenance practices to ensure a proper seal and avoid pressure build-up issues.
Insufficient liquid level
Adequate liquid is paramount for a pressure cooker’s operation.
It is through the vapors of this liquid, typically at least one cup (200 to 220 ml), that the device generates the steam necessary to build the pressure.
Without sufficient liquid, the cooker may take an inordinate amount of time to pressurize or may not pressurize at all.
In stovetop pressure cookers, this can be observed when food spews instead of releasing steam.
Users must always ensure there is enough liquid in the pot based on the recipe and the size of their pressure cooker.
Overfilled inner pot
An overfilled pot is a recipe for a malfunction.
Most pressure cookers have a maximum fill line that indicates a safe level — generally no more than two-thirds full, and even less when cooking foods that foam or expand, like grains and legumes.
Overfilling not only creates the risk of clogging the steam vent but also can cause food to eject during a quick release, creating a messy and potentially dangerous situation.
Observing the proper fill level is integral to the prevention of pressure-related issues.
Cleanliness of the inner pot
The integrity of pressure cooking is also affected by the condition of the inner pot.
After each use, especially if a burn notice is received, the inner pot should be thoroughly cleaned to remove any burned or stuck-on food.
Foods that contain starch, like pasta or rice, tend to stick to the bottom, which can impede the cooker’s ability to generate and regulate pressure correctly.
By keeping the pot clean and ensuring any food particles or browned bits are removed, the appliance can function properly and safely.
Regular cleaning and checking of the sealing ring are also important steps to maintain a cooker’s ability to pressurize effectively.
By understanding and addressing these common issues with pressure cookers, users can ensure that their meals are cooked efficiently and safely under pressure.
Regular maintenance checks and adherence to proper usage guidelines can keep the pressure cooker running smoothly for a long period of time.

Checking the pressure release valve
Start by inspecting the pressure release valve, a vital component for maintaining internal pressure.
If it’s obstructed by food particles or residue, it can prevent the cooker from sealing properly.
When the steam release valve or button of a pressure cooker like an Instant Pot is stuck or clogged, it could hinder the lid from securing, as it relies on a complete pressure release to unlock.
Additionally, as steam escapes during the initial phase, it’s normal; however, once the pressure cooker reaches the SEALING position with no further steam release, it indicates a proper seal.
Be vigilant about not overfilling the cooker to avoid impeding pressure buildup and causing longer heating periods or undercooking issues.
Inspecting the sealing ring
The sealing ring creates an airtight lock critical for pressure building.
When the ring is out of place, dirty, or damaged, the lid won’t seal correctly.
A stretched or cracked ring won’t facilitate pressure buildup and should be replaced.
If the ring is simply dislodged, repositioning is often a quick fix.
If expanded from use, cooling it in a freezer can help it contract. Regular cleaning and inspection can prolong its life and performance, ensuring a continued proper seal.
Ensuring adequate liquid
The presence of a sufficient amount of liquid is fundamental for the pressure cooker’s operation.
A minimum of 200 to 220 ml is essential for pressure to build correctly, with one cup of liquid advised due to lower evaporation in pressure cooking compared to traditional methods.
Liquid in a pressure cooker means true liquid forms like water or broth; thickened sauces could hamper steam generation.
An overabundance of liquid can also be an issue, leading to potential steam vent blockage by food items and preventing necessary pressure achievement.
Cleaning the lid and float valve
Keeping the Instant Pot lid and matching base area clean is vital.
Starch-rich or messy dishes can cause obstructions in the anti-block shield and float valve, preventing correct sealing.
Remove and clean these components regularly with a toothbrush and soapy water to ensure their functionality.
Also, clean the float valve hole to eliminate blockages that could hinder pressure sealing.
Clearing the steam vent of any food buildup is equally important to avoid malfunctions and guarantee safe pressure cooking.

When it comes to pressure cooking, ensuring that your equipment is functioning properly is key to successful meal preparation.
One common issue that users might face is that their pressure cooker is not building pressure.
This malfunction can be attributed to various scientific reasons linked to the mechanics and operation of the pressure cooker.
At the heart of pressure cooking is the concept of sealed, high-pressure steam cooking.
When heat is applied to the pressure cooker, the internal temperature rises, causing the liquid inside to form steam.
This steam increases the internal pressure.
The pressure valve is a critical component that helps to regulate the internal pressure by releasing excess steam to maintain the desired pressure levels within the cooker.
If a pressure cooker fails to build pressure, it may be due to a compromised seal between the lid and the pot.
A proper seal is essential to prevent steam from escaping. The sealing position of the lid must be in the correct position.
The silicone or rubber gasket, which is responsible for creating an airtight and steam-tight seal, could also be worn out, improperly placed, or dirty, preventing a proper seal.
Moreover, adequate liquid is necessary for generating steam.
Always ensure a minimum of one cup of liquid is present in the cooker to build enough steam for pressure cooking.
If the contents are too dry or there is insufficient liquid to vaporize, pressure will not build.
Sometimes, the issue might be with the pressure valve or steam release valve itself.
If the valve is obstructed, for example, by food particles or residue from cooking tomato sauce or similar ingredients, it can prevent the vent pipe from properly releasing or containing steam.
An obstructed vent pipe will not allow the cooker to build the required pressure.
For electric pressure cookers, like an 8-quart Instant Pot or a 3-quart Instant Pot, ensure that the pressure cooking program is selected accurately and the countdown timer begins to ensure the internal pressure is being built.
Additionally, for stovetop pressure cookers, ensure a consistent heat source and that the cooker is placed on a flat surface to distribute heat evenly.
Lastly, always handle your pressure cooker with care, ensuring not to force-open the lid but to use the quick release or natural pressure release as advised by the manufacturer.
This preserves the integrity and safety mechanisms of the cooker.
Understanding these scientific principles and performing regular checks on the pressure cooker’s components can help troubleshoot and remedy situations where a pressure cooker is not building pressure.
Proper filling techniques
