Instant pot Hissing while cooking (How to fix?)

Instant pot Hissing while cooking – Everything You Need to Know

If you’ve just got an instant pot and wonder what’s happening when it makes that noise, wonder no more. Today, we will cover everything you need to know about the hissing sound your instant pot makes while cooking. We’ll answer everything from what it means to how to fix it.

So, keep reading to learn more.

Is It Normal for A Pressure Cooker to Hiss While Cooking? 

Yes, it’s normal for your instant pot to make a hissing sound while cooking. When the pot is heating up, the moisture in the air turns to steam and escapes through any opening–including the valve. This is what makes the sound. As the pot continues to heat up, the pressure inside will continue to build until it’s at the set level, at which point the hissing will stop.

Your instant pot has a release valve that releases steam and makes a hissing sound. When the pressure cooker is turned on, the release valve pops up and makes a hissing noise. The purpose of the release valve is to let steam escape so that the pressure cooker doesn’t explode. When the food is cooked, the hissing stops.

If the hissing sound bothers you, you can turn off the pressure cooker and let the steam escape before cooking the food. Or, you can place a towel over the release valve to muffle the sound. Either way, there’s no need to worry about the hissing sound—it’s normal.

Instant Pot Won’t Stop Hissing; What to Do?

If your instant pot won’t stop hissing, turn it off, unplug it, and plug it back in. Many times, when an electronic device (like an Instant Pot) starts making a noise, it’s because something is blocking its fan from running properly.

If unplugging and re-plugging the device doesn’t work, you may need to separate it and clean out any blockages. Also, if your instant pot’s lid gasket is not correctly sealed, remove the lid and tightly close it to ensure the steam doesn’t have leeway.

Why Do Instant Pots Make Hissing Noise?

Your Instant Pot emits an occasional high-pitched hissing noise when it’s operating. But have you ever wondered what causes that sound and whether it’s normal or not?

Let’s take a look at some of the possible reasons for the Instant Pot’s hissing noise to understand this problem better: 

  • Instant Pot not Properly Sealed

The hissing and rattling sounds can be alarming, but they’re usually nothing to worry about. Usually, these sounds indicate that the pot is not properly sealed.

To seal the pot properly, you’ll need to make sure that the lid is on correctly and that the sealing ring is in place. If the pot is not sealed correctly, steam can escape, which can cause the pressure to build up and make the pot noisy.

  • Insufficient Amount of Liquid

Have you ever put too little liquid in your Instant Pot and had it start hissing at you? If so, you’re not alone. The Instant Pot is a popular kitchen appliance, but it can be finicky if you don’t use it correctly. One of the most common mistakes is not adding enough liquid.

The Instant Pot relies on steam to build pressure and create heat, so it will start to hiss if there’s insufficient liquid. In addition, the food can start to stick to the bottom of the pot and burn. To avoid this, always add at least 1 cup of liquid (preferably water) to your Instant Pot before cooking.

By following this simple rule, you can help ensure that your food turns out delicious every time.

  • High-Pressure Build-Up

One thing you need to watch out for is the instant pot’s pressure. If there’s too much pressure in the pot, it will start to make a hissing sound. This is your cue to release some pressure before it gets too high. Otherwise, you risk the food exploding and making quite a mess.

So, if you hear that telltale hissing sound, be sure to manually release some of the pressure before it builds up too much.

How do you Stop an Instant Pot from Making Hissing Noise?

If that constant hissing sound from the instant pot disturbs you, fret not because some easy tips are enough to resolve this issue. Here’s what you can do to stop your instant pot’s hissing sound:

  • Carefully Seal the Lid Gasket 

The hissing sound is caused by a poor seal between the pot’s lid and gasket. Steam builds up inside the pot when the pressure cooker is turned on. If the lid is not properly sealed, the steam will escape through any gaps, causing a distinctive hissing sound.

In addition to being annoying, the hissing sound can also be dangerous. If too much steam escapes, it can cause the pressure cooker to become unstable and possibly even explode.

Therefore, it is important to ensure that the gasket is carefully sealed before turning on the Instant Pot. You can help prevent accidents and ensure that your food is cooked evenly.

  • Don’t Overfill the Pot

The instant pot’s hissing sound can be startling and even a bit off-putting. But there’s no need to worry – the sound is simply caused by steam escaping from the pot. However, if the pot is overfilled, the steam will build up pressure and cause the lid to blow off. To avoid this, make sure not to fill the pot more than two-thirds full. Additionally, release any built-up pressure before opening the lid. 

  • Add the Optimum Amount of Liquid

If you’ve ever used an instant pot, you know that adding the right amount of liquid is essential. If you don’t, the pot will rattle and make a hissing noise. This can be extremely annoying, and it can also lead to your food not cooking properly.

So how much liquid should you add to your instant pot? The answer depends on what you’re cooking. You’ll need at least 1 cup of liquid for rice or pasta. You’ll need 2-3 cups of liquid for stews or soups. And for meat or poultry, you’ll need at least 1 cup of broth or water.

So next time you use your instant pot, make sure to add the right amount of liquid for perfect results.

Final Thoughts

The pressure cooker is one of the most versatile kitchen appliances, cooking food quickly and thoroughly while preserving nutrients. However, if the pressure gets too high, the cooker will release steam through a valve to prevent an explosion. While this safety mechanism is important, it can be frustrating if you’re trying to cook a meal and the pressure cooker keeps releasing steam.

One way to prevent this is to ensure that the venting knob is in the correct position. If it’s turned to “venting,” the pressure will be released too quickly and cause the hissing sound. However, if it’s turned to “sealing,” the pressure will build up properly and won’t hiss. Another tip is to check the gasket around the lid to ensure no cracks or gaps. A well-sealed pressure cooker will prevent steam from escaping, preventing the hissing sound.
