Instant Pot: Steam Release While Cooking, Safe Or Not?

Instant Pots are a popular choice for home cooks due to their versatility and convenience. However, some users have reported issues with steam leaking from the pot during the cooking process, which can affect the pressure cooker's functionality. While a small amount of steam escaping during the initial warming-up phase is normal, continuous steam leakage during pressure cooking indicates an issue that needs to be addressed. This guide will explore the possible causes and solutions for this common problem.

A small amount of steam leaking is normal

A small amount of steam leaking from the Instant Pot is normal. However, if there is a lot of steam coming out from the release valve during the pressure-cooking step, then there may be an issue with the sealing mechanism.

Firstly, ensure that the lid is firmly closed and the clasp is in place. If the pot is sealed correctly, then the issue may be with the valve. Take the valve out and clean it, checking for any dirt or grime that may be preventing it from sitting properly. It is recommended that you regularly clean and readjust the valve to prevent damage and ensure correct functioning. If cleaning and readjusting the valve does not work, then you may need to replace it.

Another potential cause of steam leakage is the sealing ring. The sealing ring may not be fitted on properly, or it may have enlarged due to excessive heat. Try placing the sealing ring in a cool place and seating it on the Instant Pot again.

If you have tried these methods and are still experiencing steam leakage, then it may be best to take the Instant Pot to an expert for repairs.

Check the valve is set to Sealing

Checking that the valve is set to "Sealing" is an important step in ensuring your Instant Pot functions correctly. The "Sealing" position captures all the pressure inside the pot, which is necessary for pressure cooking.

To set the valve to "Sealing", first, make sure the lid is locked. There is a triangle mark on the lid, which should be aligned with the "unlocked" mark on the side of the rim. Then, turn the lid 30 degrees clockwise until the triangle mark aligns with the "locked" mark. Now, turn the pointed end of the pressure release handle (also called the steam release handle, venting knob, or pressure valve) on top of the lid to the "Sealing" position.

If your Instant Pot is not sealing, there are several possible reasons for this, many of which are related to the valve position. First, check that the lid is locked correctly, as described above. Next, ensure that the pressure release handle is properly seated. If it isn't, push it in all the way and move it from "Sealing" to "Venting" a few times so it sits properly. If the steam release handle is missing, you will need to replace it.

Another possible issue is that the steam release handle is in the "Venting" position. Different models of Instant Pot have different pressure release mechanisms, but in general, the venting knob can be turned from "Venting" to "Sealing". If the steam release button is up, it is in the sealing position, and if it is down, it is in the venting position. If the steam release switch is in the "Vent" position, slide it into the "Seal" position.

If your Instant Pot is still not sealing, there may be another issue. Check out this troubleshooting guide for further help.

Check the sealing ring is fitted properly

If your Instant Pot is releasing steam while cooking, it could be due to an issue with the sealing ring. Here's how to check if the sealing ring is fitted properly:

First, ensure that the sealing ring is attached correctly. There should be silicone visible both above and below the metal ring. Check that the silicone ring is installed properly and aligned with the metal ring in the centre groove. If the sealing ring is not fully aligned, the lid will not seal properly. Use a dull-ended object, such as a wooden spoon or plastic utensil handle, to gently press the sealing ring down if necessary. Do not use anything sharp that may damage the ring.

Next, spin the sealing ring around on the rail that holds it onto the lid. If it spins freely, it is fine and will seal. If it comes off the rail, it was not attached correctly. This check must be done before cooking, as it will be difficult to spin the ring once it is hot.

If you notice steam escaping, turn off the Instant Pot, release the pressure, and check the silicone ring again. If it has shifted, it is time to replace it. If the ring is still attached correctly, double-check that the small silicone disc underneath the steam valve is attached correctly.

Additionally, check that the lid is locked before starting pressure cooking. There should be a triangle mark on the lid that aligns with the "unlocked" mark on the side of the rim. Turn the lid 30 degrees clockwise until it aligns with the "locked" mark. Also, ensure that the pointed end of the pressure release handle on top of the lid is in the "sealing" position to capture all the pressure inside the pot.

Finally, if you have recently purchased your Instant Pot, it may be a good idea to perform a "water test" to familiarise yourself with the appliance. Close the lid and ensure the knob is in the sealing position. Use the manual or steam function and set the time for 2 minutes. You will notice the floating valve pop up when the high pressure is reached. Once the screen turns to "warm/cancel" mode, you can release the steam naturally or perform a quick release before opening the lid.

Clean and readjust the valve regularly

It is important to regularly clean and readjust the valve of your Instant Pot to ensure it functions properly and safely. Here is a detailed guide on how to do this:

Locate the float valve, which is the red or silver pin on the lid of the Instant Pot. It is important to know what this looks like in both the up and down positions. When the float valve is up, the pot is pressurised, and when it is down, the pot is not pressurised.

To clean the float valve, first, remove the silicone cap from the end that is inside the lid. Wash both the float valve and the cap in warm, soapy water. Reattach the float valve to the lid and secure it with the silicone cap. Ensure that the float valve can move up and down easily without obstruction.

If the float valve gets stuck in the up position after releasing pressure, gently tap it with a wooden spoon or chopstick. This can happen if food particles get stuck to the valve. In this case, be sure to remove and clean the valve. It is also a good idea to remove and clean the float valve regularly to prevent it from getting stuck.

Additionally, the steam release handle, anti-block shield, and float valve should be checked regularly for residue or food particles. These parts may need to be cleaned or unscrewed for proper maintenance. The anti-block shield, for example, should be unscrewed and cleaned if you use the quick-release function regularly or cook sticky foods.

By following these steps, you can ensure that your Instant Pot's valve is clean and functioning properly, which is essential for safe and effective pressure cooking.
