The Instant Pot, a modern kitchen marvel, has revolutionized cooking for many, promising speed, convenience, and consistent results. However, even the most reliable appliances can occasionally throw a curveball. One common issue that frustrates Instant Pot users is the dreaded “On” display, where the pot simply displays the word “On” instead of counting down the cooking time. This seemingly simple message can be surprisingly complex, pointing to various underlying causes. Understanding these causes and their potential solutions is crucial to getting your Instant Pot back on track and enjoying hassle-free cooking.
Understanding the “On” Display: More Than Just a Waiting Game
When your Instant Pot displays “On,” it generally indicates that the appliance is in a preheating phase or is actively maintaining a specific temperature or pressure after the cooking cycle is complete (Keep Warm mode). However, if the Instant Pot remains stuck on “On” for an extended period without transitioning to the countdown timer or if you didn’t intend to use Keep Warm, there’s likely a problem that needs addressing.
The key to resolving this issue lies in accurately diagnosing the reason behind the prolonged “On” display. Is it a simple user error, a minor mechanical glitch, or a more serious malfunction? Let’s delve deeper into the most frequent culprits.
Insufficient Liquid: The Foundation of Pressure Cooking
Pressure cooking relies on steam, which is generated from liquid inside the pot. Without enough liquid, the Instant Pot struggles to reach the necessary pressure, preventing the timer from starting. This is arguably the most common reason for the persistent “On” display.
Different recipes and models of Instant Pots require varying amounts of liquid. Always consult your recipe and Instant Pot manual for specific instructions. Generally, most Instant Pot models require at least one cup of liquid to function correctly.
If you suspect insufficient liquid, carefully release the pressure (using the quick release or natural pressure release method), open the lid, add more liquid, and restart the cooking process. Ensure the liquid is appropriate for the recipe – water, broth, or sauce are common choices. Avoid using thickeners like cornstarch or flour before pressure cooking, as they can impede steam generation and potentially burn.
Incorrect Sealing: A Leak in the System
A proper seal is paramount for pressure to build up inside the Instant Pot. Any leak, however small, can prevent the pot from reaching the required pressure, causing it to remain stuck on “On.”
Several factors can contribute to a faulty seal.
Checking the Sealing Ring: The First Line of Defense
The sealing ring, typically made of silicone, is responsible for creating an airtight seal between the lid and the pot. Over time, the sealing ring can become worn, cracked, or stretched, compromising its ability to seal effectively.
Inspect the sealing ring for any visible damage. Remove it from the lid and clean it thoroughly with soap and water. Ensure it’s properly seated in its groove on the lid. If the sealing ring appears damaged or doesn’t fit snugly, it needs to be replaced. Many Instant Pot users recommend having a spare sealing ring on hand, especially if they use their Instant Pot frequently.
The Steam Release Valve: Open or Closed?
The steam release valve, also known as the pressure release valve, controls the release of steam from the Instant Pot. For pressure cooking, this valve must be in the “Sealing” position (or “Pressure,” depending on the model). If the valve is left in the “Venting” position, steam will continuously escape, preventing pressure from building up.
Double-check that the steam release valve is correctly positioned for pressure cooking. Some valves are loose-fitting and can be easily bumped out of place, so make sure it’s securely in the sealed position.
Debris and Obstructions: Keeping Things Clean
Food particles and debris can accumulate around the sealing ring, the steam release valve, and the rim of the inner pot, interfering with the seal.
Thoroughly clean all components of the Instant Pot, paying close attention to the sealing ring, the steam release valve, and the rim of the inner pot. Use a soft sponge or cloth to remove any food residue. Avoid using abrasive cleaners, as they can damage the sealing ring and other parts.
Food Blocking the Steam Release Valve: A Pressure-Building Impairment
Sometimes, food particles can splatter and block the steam release valve, even when it’s in the sealing position. This blockage can cause inconsistent pressure and prevent the Instant Pot from transitioning to the cooking timer.
Ensure the steam release valve is clear of any obstructions. A simple test is to gently poke the valve with a toothpick or small skewer to ensure it moves freely. If there is any blockage, carefully remove it before restarting the cooking process.
Float Valve Issues: A Pop-Up Problem
The float valve is a small pin that pops up to indicate that the Instant Pot is under pressure. If the float valve is stuck or malfunctioning, it can prevent the pot from reaching pressure or falsely indicate that pressure has been reached when it hasn’t.
Check if the float valve moves freely. Sometimes, food debris can prevent it from popping up or down properly. Clean the float valve and the area around it thoroughly. You may need to gently push the float valve up from the underside of the lid to loosen it.
Burn Error: The Silent Saboteur
Although it might not display a specific “Burn” message immediately, a developing burn error can manifest as the Instant Pot staying on “On” indefinitely. This happens when food is stuck to the bottom of the inner pot and begins to burn, triggering the Instant Pot’s safety mechanisms to prevent overheating.
If you suspect a burn error, immediately release the pressure and check the bottom of the inner pot for any signs of burning. If food is stuck and burning, carefully remove the burnt food and clean the pot thoroughly. To prevent future burn errors, ensure there is enough liquid in the pot, avoid using thickeners before pressure cooking, and consider using the pot-in-pot (PIP) method for delicate recipes.
Delayed Start: A Pre-Programmed Pause
Some Instant Pot models offer a delayed start function, allowing you to program the appliance to begin cooking at a later time. If you accidentally set a delayed start, the Instant Pot will display “On” until the programmed start time arrives.
Check if you have inadvertently activated the delayed start function. If so, either wait for the timer to expire or cancel the delayed start and begin cooking immediately. Consult your Instant Pot manual for instructions on how to cancel the delayed start.
Keep Warm Function: Maintaining the Heat
The Keep Warm function automatically activates after the cooking cycle is complete, keeping the food warm until you are ready to serve it. While useful, it can sometimes be mistaken for a malfunction if you are expecting the Instant Pot to turn off automatically.
If your Instant Pot is displaying “On” after the cooking cycle, check if the Keep Warm function is activated. If you don’t need to keep the food warm, simply press the “Keep Warm/Cancel” button to turn off the function.
Electrical Issues: A Power Play
Although less common, electrical issues can sometimes cause the Instant Pot to malfunction and display “On” indefinitely. These issues can range from a simple power outage to a more complex problem with the Instant Pot’s internal circuitry.
Ensure the Instant Pot is properly plugged into a working outlet. Try plugging another appliance into the same outlet to verify that it is providing power. If you suspect an electrical issue, it is best to consult a qualified electrician or contact Instant Pot customer support for assistance. Do not attempt to repair the Instant Pot yourself, as this could be dangerous and may void the warranty.
Control Panel Problems: The Brain of the Operation
The control panel is the central nervous system of the Instant Pot, responsible for controlling all of its functions. If the control panel is malfunctioning, it can cause a variety of issues, including the persistent “On” display.
Try resetting the Instant Pot by unplugging it for a few minutes and then plugging it back in. This can sometimes resolve minor glitches in the control panel. If the problem persists, the control panel may need to be replaced. Contact Instant Pot customer support for assistance.
A Deeper Dive into Specific Instant Pot Models
While the general troubleshooting steps outlined above apply to most Instant Pot models, there can be subtle differences in functionality and error messages between different models. Consulting your specific Instant Pot model’s manual is always recommended.
For example, some models have more sensitive sensors that are prone to triggering burn errors more easily. Others have different pressure settings that require careful adjustment depending on the recipe. Understanding the nuances of your specific model can help you diagnose and resolve the “On” display issue more effectively.

The Instant Pot, with its myriad functions and cooking capabilities, can be a valuable asset in any kitchen. While the “On” display can be a source of frustration, understanding its underlying causes and implementing the appropriate solutions can help you get your Instant Pot back on track and enjoy all of its benefits. By following the tips and advice outlined in this article, you can master your Instant Pot and become a confident pressure cooker. Remember, a little troubleshooting can go a long way in ensuring that your Instant Pot remains a reliable and efficient kitchen companion for years to come.
Why does my Instant Pot display “On” but not the cooking time, even after pressing start?
The “On” display indicates the Instant Pot is powered and in standby mode, waiting for the pressure to build or the cooking program to begin. It’s a preliminary stage, not necessarily an error. Often, the pressure cooker is simply taking time to heat the contents of the inner pot and build pressure. This is especially common when cooking with cold ingredients or larger quantities of food.
If the “On” display persists for an extended period (longer than 20-30 minutes, depending on the recipe and the model), several factors might be at play. Check that the sealing ring is correctly installed on the lid. Ensure that the steam release valve is in the “Sealing” position. Also, confirm there is sufficient liquid in the inner pot; most Instant Pot recipes require a minimum amount of liquid for proper pressure cooking.
What does the “On” display mean on my Instant Pot, and is it a cause for concern?
The “On” display on your Instant Pot is a normal indication that the appliance is powered on and ready to begin the cooking process. It’s essentially a standby mode. This display will remain until the pressure inside the pot reaches the required level or the pre-programmed cooking cycle is initiated, such as with non-pressure cooking functions like sauté.
While seeing “On” is generally not a cause for immediate concern, it’s important to monitor the situation. If the display remains unchanged for an unusually long time, especially after selecting a cooking program, then troubleshooting is necessary. This prolonged “On” state might indicate an issue with pressure build-up, heating element, or sensor malfunction.
How long should my Instant Pot stay on the “On” display before it starts counting down the cooking time?
The time your Instant Pot remains on the “On” display varies based on several factors. These factors include the initial temperature of the food and liquid, the quantity of food being cooked, and the specific Instant Pot model. Typically, it can take anywhere from 5 to 20 minutes for the pressure to build sufficiently for the timer to begin counting down.
If your Instant Pot takes significantly longer than 20-30 minutes, consider checking for common issues. Ensure the sealing ring is properly seated and undamaged. Make sure the steam release valve is closed. Verify there is enough liquid in the pot, as insufficient liquid can prevent pressure from building. Also, ensure that the heating element is functioning correctly.
My Instant Pot is stuck on “On,” and I’ve already checked the sealing ring and valve. What else could be the problem?
If you’ve already confirmed the sealing ring is correctly installed and the steam release valve is in the “Sealing” position, the next step is to investigate the amount of liquid in the pot. Insufficient liquid is a common culprit for the “On” display persisting. The Instant Pot needs enough liquid to generate steam and build pressure. Refer to your recipe to ensure you’ve added the correct amount.
Another potential issue could be the heating element or the pressure sensor. A faulty heating element may not be generating enough heat to create steam, while a malfunctioning pressure sensor might be inaccurately reporting the pressure levels. In these cases, contacting Instant Pot support or a qualified appliance repair technician is recommended.
Can using the wrong settings cause my Instant Pot to stay on “On” indefinitely?
Yes, incorrect settings can definitely cause your Instant Pot to remain on the “On” display for an extended, perhaps indefinite, period. Selecting the wrong pressure level (e.g., using “Low Pressure” when “High Pressure” is required) can significantly lengthen the time it takes to build pressure, giving the impression that the Instant Pot is stuck.
Furthermore, using a non-pressure cooking setting by mistake (such as “Sauté” or “Yogurt”) instead of a pressure cooking setting will prevent the Instant Pot from ever reaching the necessary pressure to start the timer. Always double-check your selected cooking program and settings before initiating the cooking cycle to ensure they align with your recipe and intended outcome.
Is it possible that my Instant Pot is defective if it consistently stays on the “On” display?
While the “On” display usually signifies the preheating stage, a persistent “On” display, despite troubleshooting the common issues, might indicate a defect. If you’ve checked the sealing ring, steam release valve, liquid levels, and settings, and the problem continues, there could be a problem with the appliance itself. Components like the heating element or pressure sensor could be faulty.
If you suspect a defect, the best course of action is to contact Instant Pot customer support. Explain the troubleshooting steps you’ve already taken and the symptoms you’re experiencing. They can offer further guidance, and if the unit is still under warranty, they can arrange for a replacement or repair. Do not attempt to repair the Instant Pot yourself, as this could void the warranty and pose a safety risk.
My Instant Pot sometimes displays “On” and other times starts counting down immediately. Why is this?
The inconsistency you’re experiencing likely relates to the factors affecting pressure build-up time. A warmer starting temperature of your ingredients will naturally lead to a quicker time to pressure. For example, using room-temperature broth versus refrigerated broth will shorten the “On” phase. Similarly, the quantity of food and liquid directly impacts the time it takes to reach the required pressure.
Another influencing factor is the specific cooking program selected. Some programs are designed to preheat more intensely than others. Also, the age and condition of the sealing ring can affect how efficiently pressure builds. An older, slightly degraded sealing ring might allow a small amount of steam to escape, prolonging the “On” display phase. Try replacing the sealing ring to see if that addresses the variability.
