Instant Pot Lid Releasing Steam: What's The Deal?

Instant Pots are a popular choice for home cooks due to their versatility and convenience. However, one common issue that users often encounter is steam leakage during cooking. While a small amount of steam release is normal, especially during the initial warming-up phase, excessive steam escape can indicate a problem with the pressure cooker's functionality. This could be due to various factors, such as an improperly sealed lid, a faulty valve, or a damaged sealing ring.

The lid may not be on tight enough

If your Instant Pot is leaking steam, it may be because the lid is not on tight enough. This could be due to a few reasons. Firstly, the lid locking pin may be stuck in the retracted position, preventing the lid from closing properly. To fix this, push on the pin from the inside and outside of the lid, or gently jiggle it to reset the spring mechanism. Secondly, check if the steam release handle is missing or not properly seated. The steam release handle needs to be pushed in all the way; if it isn't, steam will leak from the valve or handle. To fix this, push in the steam release valve and move it from the sealing to the venting position a few times so it sits properly. Thirdly, ensure that the sealing ring is properly seated. An unevenly set ring can create a partial seal, allowing steam to escape from the edges of the lid. Check that the sealing ring is evenly seated under the wire all the way around the edge of the lid and try to turn it in place. If the sealing ring is damaged or torn, you may need to purchase a new one. Finally, make sure that the lid area and liner are clean and free of food debris. If food is stuck to the rim of the inner pot, the seal will not be tight when you close the lid, allowing steam to escape. Use a cloth or clean toothbrush to wipe around the rim of the lid and the base unit, and thoroughly clean the inside, outside, and rim of the inner pot.

The valve needs adjusting

If your Instant Pot is leaking steam during the pressure-cooking stage, the valve may need adjusting.

First, check that the pressure cooker has been tightly sealed and the lid has been firmly closed. Ensure the clasp is in place. If this doesn't solve the problem, the main reason for the steam leak is likely that the valve needs to be adjusted properly. Take the valve out and place it in properly. It's also recommended that you clean the valve whenever you remove it.

You should regularly clean and readjust your Instant Pot's valve, even if there isn't any steam leaking. This will ensure that the valve doesn't get damaged and become faulty. Over time, dirt and grime will build up around the valve, so it's important to clean it with a toothpick or something similar to get the grime out before placing the valve back in. If you don't clean it properly, it won't sit correctly, and there will be a tiny gap that could cause steam to leak out. This could also negatively impact the performance of your Instant Pot.

If cleaning and adjusting the valve doesn't solve the problem, you may need to replace the valve entirely. You can find replacement valves online or in specific stores.

The valve needs cleaning

If your Instant Pot is leaking steam during the pressure-cooking stage, it could be because the valve needs cleaning. It is recommended that you clean the valve properly whenever you remove it. This is because, over time, dirt and grime will build up around the valve, and there are tiny gaps and nooks where dirt can get stuck. You can use a toothpick or something small to get the grime out before you place the valve back in. If you don't clean it properly before reinserting it, it won't sit properly and there will be a tiny gap that could cause steam to leak out. This could also negatively impact the performance of your Instant Pot.

You should regularly clean and readjust your Instant Pot valve, even if there isn't any steam leaking. This will ensure that the valve doesn't get damaged and become faulty. Valves tend to become faulty over time, so you'll have to replace them every few months. You can find replacement valves online or in specific stores.

The sealing ring is not fitted properly

If your Instant Pot is leaking steam, it could be because the sealing ring is not fitted properly. This is a common issue with the appliance and can be easily fixed.

First, check if the sealing ring is damaged. If you notice any holes, tears, or cracks in the silicone, you will need to replace it. The sealing ring is responsible for creating an airtight seal, so any damage can result in steam escaping.

If the sealing ring appears intact, ensure it is properly seated. It should be placed snugly under the wire rack, allowing it to move or rotate with a bit of effort. If the ring is not seated correctly, it may cause steam to leak from the sides of the lid. Try pushing the sealing ring down all the way around the ring rack and then turn it to ensure it is properly seated.

Additionally, make sure the sealing ring is not too dry. Before placing the lid on the Instant Pot, turn it upside down and fill it with water just above the bottom of the sealing ring. Manipulate the ring slightly to ensure water runs underneath, then pour out the excess water before placing the lid on the pot.

If you have recently cooked something, the sealing ring may be expanded due to heat exposure. In this case, try placing the sealing ring in the freezer or running it under cold water to contract it before reseating it.

Finally, check that the sealing ring is free of debris and food particles. Clean it with soap and water, ensuring no food is stuck to the ring. A dirty sealing ring can prevent a proper seal from forming.

The sealing ring is damaged

If your Instant Pot is leaking steam during the pressure-cooking stage, it could be because the sealing ring is damaged. The sealing ring is the plastic ring that fits around the inside of the lid. If it is cracked, leaking, or deformed, it will need to be replaced.

Sealing rings are not expensive, and it is recommended to have more than one, as they can be difficult to clean and may retain odours even after cleaning. You can buy packs of two sealing rings in different colours, allowing you to keep one for savory dishes and one for sweet.

To clean a sealing ring, you can put it in the dishwasher, wash it with warm soapy water, or use the steam-cleaning method. To steam-clean, fill the Instant Pot insert with two cups of white vinegar or water and a lemon rind, seal the lid, and run the appliance on the "steam" setting for two minutes. Then, remove the ring and let it air dry.
