 Even though pressure cookers have come a long way – thanks to advanced technology and improvised mechanisms, the diverse usage of this creation is still endless.

On the other hand, although the safety proportions have boosted with pressure cookers immensely, often we find ourselves searching for answers to a question – why is pressure cooker steam coming out of safety valve and how to solve it?

Worry not; we have identified the issues and remedies to this frustration. Keep reading to know all about it.

Reasons Why Pressure Cooker Steam Coming Out Of Safety Valve

While some might say that this complaint isn’t exactly dangerous, it’s still an issue you need to fix immediately.

But, before you hop onto fixing this stressful malfunction, you must observe why it’s occurring. If the base of the problem is found, the solution will trigger effective results.

Let’s take a look at a few common reasons for this issue before explaining the remedies.

  1. The Basic Operation

Believe it or not, but while cooking as the pressure cooking goes through an immense amount of pressure circulating on the interior, it could often cause mishaps.

Even with the cover whistles and heavy steam releaser, seldom do these mechanisms fail with constant usage.

Thus, as the pressure stress on the inside keeps rising steadily, the safety valves on the other end of the pressure cooker will comprehend the risks and start functioning.

As the safety valves try to release some of this built-up pressure, you might witness the steam appearing out along with a hissing noise. This can also be accompanied by a wobbly cover lid of the pressure cooker.

  1. It’s Too Old!

If your pressure cooker is a good couple of years old, the safety valves will open up to release years of built-up pressure.

  1. Unknown Brand

You must carefully select the pressure cooker brand. Occasionally, in the midst of not wanting to spend an arm and a leg, we might put our eggs in the wrong basket with a pressure cooker with below-average features and quality.

Even within a budget, you can score branded pressure cookers that can eradicate safety and health hazards.

  1. Damaged Gasket

In a more technical sense, there could be damage in the gasket or beneath the rim, which causes the pressure cooker’s safety valve to start leaking.

  1. Poor Maintenance

Lastly, flunking off regularly, cleaning, and maintaining this device will come to an eventual downfall for the pressure cooker.

What might start with mere faulty safety valves can ultimately break down its full functionality.

Solution For Pressure Cooker Safety Valve Leaking

As pressure cookers have become intuitive, it’s safe to say the hands-off approach will clear up the coagulated steam all by itself, bit by bit.

Due to this exquisite experience, all you have to do is wait for the safety valve to clean up gradually.

In retrospect, even with the long waiting, there are certain benefits of this slow process as the pressure cooker cleans up itself from within.

Hence, if you see steam coming out of the valves during this course of time, do not panic.

Furthermore, before you start cooking, check the safety valves thoroughly to ensure that they can endure another batch of cooking food, creating pressure and releasing steam from the correct channels.

In this manner, even with the hissing sound and functioning safety valves, you will know if there’s a leak and if all the components are working as presumed.

Pressure Cooker Leaking Steam From Sides

Noticing a little steam escaping the sides of the pressure cooker while cooking is quite usual.

However, if steam comes out of the sides even after the cooker has released its pressure or completed cooking, it could be indicating an issue.

Why Is It Happening?

We could mostly sum up three reasons for this situation to take place. While this might seem genuinely troublesome, the remedies are pretty simple as well.

Keep reading to know why you could witness steam blowing out from the edges of your pressure cooker and what to do to fix it.

  • Probably Nothing!

If you witness steam coming out during the pressurization stage, do not panic!

While there’s a build-up of pressure within the pressure cooker, you can notice smoke blowing off from the pressure valve or sides of the cooker, which is normal.

As your pressure cooker finishes cooking and cools down, the steam blow-off should disappear entirely.

  • Forgetting To Turn On The Sealing Feature

A few pressure cooker models can set themselves to an option called “sealing,” whereas others could manually set them.

The most common mistake is when users forget to turn on the ‘sealing’ feature manually. This traps the steam in a manner that forces it to escape from the sides of the safety pressure valve channel.

  • Forgetting The Lid

Lastly, if you fail to seal or cover the pressure cooker adequately with the lid, you might face this scenario.

These mishaps could even lead to failure of the pressure cooker in building up pressure wholly or delayed timing in building pressure. And when it finally does, you might see steam coming off from the edges.

How To Fix It?

Here are a few tips to get rid of this issue with your pressure cooker. If you notice this issue amid cooking, we recommend you finish up and then try these techniques. Here’s what you need to do.

  • Pressure cookers are innovated with a silicon ring inside the seal. Check if the silicon is attached to the lid.
  • Next, check if the silicon seal is correctly placed around the ring. You should find it beneath the wire, covering the entirety of the lid’s edge. When the seal ring doesn’t cover the top appropriately, the steam might escape from the sides due to built-in pressure.
  • If even after placing the silicon ring correctly, you notice that the steam is still blowing out from the wrong places, you might want to go ahead and replace it with a new ring.

Cook Your Food Safely

Whether you keep your pressure cooker in tip-top shape depends on how you use and maintain it. Yes, cleaning goes a long way, but there’s a lot more to kitchen safety when dealing with intricate appliances such as pressure cookers.

Skim through to know how to safely maintain and cook in a pressure cooker for the long run.

  • Always add liquid into your cooker as advised in the pressure cooker manual. The minimum level of water and food items will ensure that the pressure build-up and releaser works promptly.
  • Remember to cover with the lid and position or close the safety valves as mentioned in the pressure cooker’s instructions.
  • Refer to the instructions manual before setting the pressure manually on the pressure cooker. Few electric pressure cookers have pre-determined and auto pressure function, which is a big-YES!
  • If you’re using a stovetop pressure cooker, we recommend cranking up the heat at the highest level. Reduce the heat as the pressure of the cooker reaches the optimum level.
  • If you’re not utilizing an automatic electric pressure cooker, ensure to turn on a digital timer to cook your food. Based on the recipe, the timer and pressure release will vary, so keep that in mind.

Pressure Cooker Maintenance Tips

Now that we know all about pressure cooker concerns and solutions, let us reveal some primary tips on maintaining your pressure cooker to boost its durability and lifelong assistance.

  • Cooker Gasket

While washing the appliance, never forget to pay attention to the gasket. The rubber ring that runs along the lid is called a gasket that most often goes without getting cleaned.

As this component stops from the steam and heat escaping, most of the dust, gunk, and oil gets accumulated here. Eventually, without sufficient cleaning, it will lose its elasticity and efficiency.

  • Vent Pipe

You need to unclog the safety pipe after each use. With releasing buildup pressure and steam, it can also get blocked with food and oil.

To clean the vent pipes, you can blow into them or grease the insides with vegetable oil instead of water.

  • Cleaning Agents

Utilizing benzene-based or chlorine cleaning agents are a big no-no. Instead, you can opt for plain water and vinegar.

Harsh cleaning agents and vigorous scrubbing can damage the pressure cooker’s top layer, electrical outlets, and rubbers.

A quicker and cheaper alternative is to use a mixture of vinegar and water. You can also supplement one tablespoon of baking powder to the mix and apply elbow grease afterward.

  • Proper Storage

It is recommended to store your pressure cooker in a clean and dry place. But here’s a secret that nobody lets out.

Open up a box of baking soda and place it inside the cooker before storing it. You might also sprinkle some soda inside that would soak up any remaining mold or moisture.

Frequently Asked Questions (FAQ)

How to know when the pressure cooker is done?

Answer: If the pressure release option is left in the sealed state, the cooking time ends there.
