Why Is My Pressure Cooker Not Whistling? (Read This First!)

A whistling pressure cooker is a common picture if you use a pressure cooker. Generally, a pressure cooker creates pressure converting water and steam.

So, when the expected pressure is achieved, the weight lifts the excess pressure. The releasing of this excess pressure causes whistling.

So, whistling is a sign of the proper functioning of the pressure cooker. If you notice the pressure cooker is not whistling, there might be some problems with the cooker.

The problem might be related to the pressure cooker or the food. However, let’s see what can be the reason that your pressure cooker is not whistling.

Why is my pressure cooker not whistling?

In general, when the cooking process is over, the pressure cooker will not whistle anymore. But some other technical issues are related. For example, the position of the lid and gasket might not be correct. A dirty and stuffed pressure cooker valve, damaged gasket might also be the reason.

Pressure cookers generally stop whistling when the desired pressure is achieved. If the pressure cooker is okay and whistles regularly at the initial stage of cooking, maybe the cooking is complete. So, the pressure cooker is not whistling.

But sometimes, the gasket is damaged, so the whistling might not happen while cooking.

Does a pressure cooker whistle?

Yes, a pressure cooker whistles if the cooker works properly. Generally, the whistle is located on a spring on the lid of the pressure cooker. So, when you start to give heat to the pressure cooker, the food inside starts to boil and creates pressure.

But the pressure can’t go away easily. It has to pass through the pressure vent of the lid. So, the increased pressure forces the gasket to raise and release the pressure.

While releasing the pressure, a whistling sound comes out. So, it’s a common function to whistle the pressure cooker.

What does it mean when a pressure cooker whistles?

When a pressure cooker whistles, it means the desired pressure is achieved. Generally, when we cook in a pressure cooker, the pressure cooker creates maximum pressure in it so that the heat can rise.

So, whistling means the excess pressure is released from inside. Moreover, the food inside is getting more temperature. So, whistling also means the inside temperature is too high. If the pressure cooker is whistling more than once, that means the food inside is ready.

Pressure cooker whistles are a common function of pressure cookers. So, if the pressure cooker is whistling, you have to know that the cooking process is continuing or the cooker is working properly.

Why is my pressure cooker not whistling and what to do to fix it?

If your pressure cooker is not whistling, there must be some problems. If you cook in a pressure cooker that doesn’t whistle, you can’t know when the cooking is over. So, there is a chance of burning or overcooking the food. So, let’s see the reasons why your pressure cooker is not whistling and how you can fix it.

Displaced lid position:

The pressure cooker releases extra pressure from the pressure vent. The pressure vent is located on the lid of the pressure cooker. So, if the position of the lid is not correct, the heat and the pressure will not pass through the pressure vent.

Moreover, if the lid is not sealed well, the heat and pressure will leak and the pressure will not build up properly. So, the pressure cooker will not whistle.


You have to tighten the lid again. So, if you notice the whistle is not working, you have to turn off the heat. Then let the pressure cooker cool down.

Open the lid and fix the lid to the right position. Again start the pressure cooker to check whether it is whistling or not.

Damaged and dirty gasket:

Sometimes, the gasket of the pressure cooker gets damaged or worn. So, the excess pressure will not release properly.

Moreover, sometimes the dirty gasket gets dirty and stuffed. If you don’t clean the gasket after every cooking, the gasket might get dirty and will not work properly.


If the gasket gets to wear on it, you can try to clean it. If it is still not working properly, you have to replace the gasket. The damaged gasket must be removed.

Moreover, you have to clean the gasket after every cooking and re-fix it again. Besides, if the pressure cooker worked for many days, you have to replace the gasket with a new one.

Extra liquid:

While cooking, adding too much liquid might cause a problem. Generally, a pressure cooker converts water or liquid into steam.

So, the steam goes out if the pressure is too high. When you add too much liquid to the pressure cooker, the pressure cooker takes too much time to release pressure or whistle. Even the pressure cooker might not whistle at all.


You can read or follow the instruction manual of the pressure cooker. Then you will know how much water you have to add to a certain food. Don’t cook too much food on the pressure cooker.

If you need to cook a large amount of food, you can choose a large pressure cooker.

Too much food:

If you cook too much food at a time in the pressure cooker, the cooker might not raise the temperature and pressure properly. So, the excess pressure will not escape from the cooker. As a result, the whistle will not work.


Don’t put too much food in the pressure cooker. You can follow the user manual to have an idea about how much food you can add to the pressure cooker.

Moreover, don’t put frozen food directly for cooking in the pressure cooker. Defrost the food first, then start cooking.

Do all pressure cookers whistle?

No, all pressure cookers don’t whistle. Generally, whistling means the excess pressure from the pressure cooker is releasing. Sometimes, the valve of the pressure cooker is lightweight and doesn’t whistle. So, let’s see which pressure cookers are whistling.

Electric pressure cooker:

Electric pressure cookers don’t whistle. Generally, electric pressure cookers, commonly known as instant pots, create hissing or shushing sounds while releasing pressure.

The quiet sound doesn’t cause any whistling. Electric pressure cookers have a built-in mechanism that reduces sounds.

Futura pressure cooker:

Futura pressure cooker whistles generally. When you start the Futura pressure cooker, the steam vent doesn’t create so much sound or whistling.

But when the pressure and temperature increase gradually, the pressure on the steam vent also increases.

So, it will create a whistling sound. So, whether the Futura pressure cooker will whistle or not depends on the pressure on it.

Tefal pressure cooker:

Like the Futura pressure cooker, the Tefal pressure cooker also whistles while increasing temperature. Generally, when you start the cooker in the initial stage, the cooker will not make a harsh sound.

The sound is more like a hissing sound. But if the pressure and temperature are too high, the pressure release will cause whistling.

Presto pressure cooker:

Presto pressure cooker doesn’t whistle so much. This pressure cooker is considered one of the quiet pressure cookers. So, when the Presto pressure cooker cooks, it releases excess pressure quietly and with a hissing sound.

How long does it take for a pressure cooker to whistle?

Generally, a pressure cooker takes three minutes to whistle on average. The time might vary with the amount of food. If you add too many foods to the pressure cooker, the whistling might not start quickly.

Moreover, if the temperature is too low, the pressure cooker will start to create steam and pressure at a low rate. So, the whistling might be late. Sometimes, it can take five to ten minutes to start the whistle.

Can I use a pressure cooker without a whistle?

Pressure cookers are many types. Many pressure cookers can cook without whistling. For example, electric pressure cookers don’t whistle. But if you want to cook in a pressure cooker that whistles, you can’t cook without a whistle.

Cooking on a pressure cooker without a whistle isn’t safe. If you cook with a whistle, you will have an idea about the stage of cooking. But some pressure cookers release excess pressure without making a sound.

Many pressure cookers are considered quiet. So, you can use those pressure cookers to avoid whistling.

Why can’t I open my pressure cooker and how to fix it?

When you can’t open your pressure cooker, it’s pretty irritating. So, you have to fix the problem and open your pressure cooker easily. So, let’s see why you can’t open your pressure cooker and how you can fix it.

Trapped pressure:

Pressure cookers are related to work in high pressure. So, the excess pressure can be trapped between the cooker and the lid. So, when this excess pressure gets trapped, you might find opening the cooker difficult.


You can heat the pressure cooker for a while. After getting the heat, the excess pressure will go away through the steam vent. So, you will open the pressure cooker then.

Jammed pressure cooker:

After cooking for some time, the residue of the food or food elements can stick between the lid and the cooker.

So, the pressure cooker can get jammed. A jammed pressure cooker will stick the lid tightly to the cooker. You will find difficulty opening the lid.


You can pour some cold water on the pressure cooker to release the jammed elements. Coldwater will release excess pressure and make it easy to open the cooker.

Sometimes, the lid is jammed. You can heat the pressure cooker again for some time to release the jammed lid.
