Water Test: Initial Walk Through with Your Instant Pot / Electric Pressure Cooker

Don’t be intimidated by your pressure cooker! If you’re new to pressure cooking and want to start slow, I recommend doing a Water Test. This is a no-worry way to familiarize yourself with your machine. 

How do to a Water Test in your Electric Pressure Cooker / Instant Pot

A water test is a great way to learn hands-on how your pressure cooker comes to pressure. It will also help you get used to the steps of pressure cooking. 

I’ve written out a lot of specific details here—you’ll repeat the steps in this water test every time you cook at pressure. However, most of these details won’t be specifically written out in the recipe. They’re just good habits to get into from the beginning.

Setting Up the Pressure Cooker for the Water Test

First, choose a place to plug in your electric pressure cooker. You’re looking for a place where the steam will vent away from cabinets and walls.

Some people choose to place it on or right next to their stovetop; however, I don’t recommend this due to the potential to accidentally turn on the stove and melt the pressure cooker. (It really happens!)

Many brands of electric pressure cookers recommend placing your cooker on a heat-resistant counter mat, especially if you plan to use your pressure cooker on a wood table. 

Check that the pressure cooker lid is properly assembled with the sealing ring in position and the float valve in place. Run your finger along the sealing ring to ensure that there are no bulges or gaps.

Double check that the inner pressure cooking pot is inside your housing. You can seriously damage your electric pressure cooker if you try to cook without the cooking pot in place inside the housing. 

Be sure to put your inner pot inside your housing when doing the Water Test in your Instant Pot / Electric Pressure Cooker

Bringing the Pot to Pressure

Add 1 cup water to the inner pressure cooking pot. (Don’t forget—the pressure cooker doesn’t work without the water!)

Close and lock the lid. Make sure the pressure release switch is in the Sealed position. Sealed is the term I use in my recipes; the exact terminology will vary by brand.

  • Instant Pot Duo: Turn the pressure release handle from Venting (steam icon) to Sealing (triple-S icon). 
  • Ninja Foodi: Turn the pressure release valve from Vent to Seal.
  • Crockpot Express: Turn the steam release valve from the Open/Release position (steam icon) to the Closed/Seal position (X over the steam icon).
  • Power Pressure Cooker XL: Turn the pressure valve from the Open position (steam icon) to the Lock position (bulls-eye icon).

Select the Manual/High Pressure setting and set 5 minutes for the cook time. Again, Manual/High Pressure is the term I use in my recipes; the exact terminology will vary by brand.

  • Instant Pot Duo: To select High Pressure, use the Pressure Cook button, then use the plus and minus buttons to set the cook time to 5 minutes. (Older models of Instant Pot should use the Manual button in place of the Pressure Cook button.) No need to press start—after a few seconds, a beep will sound and it will start cooking according to your selections.
  • Ninja Foodi: To select High Pressure, press the Pressure button, then use the up and down Temp arrows to choose High. Then, use the up and down Time arrows to set the cook time to 5 minutes. Then press the Start/Stop button to begin the cooking process.
  • Crockpot Express: This pressure cooker doesn’t allow you to set a Manual cook time; therefore, you’ll need to choose the button with the closest cook time. For this recipe, select the Steam button and use the plus and minus buttons to adjust the cook time to 5 minutes. Press the Start/Stop button to begin the cooking process.
  • Power Pressure Cooker XL: Since this pressure cooker doesn’t allow you to set a Manual cook time, you’ll need to choose the button with the closest cook time. For this recipe, select the Rice/Risotto button and, if necessary, use the Time Adjust button to set a 6 minute cook time.

Now, sit back and let the pressure cooker do all the work. It takes about 5 minutes for the water to heat up and build pressure.

Different brands of pressure cookers show the pressure building in different ways—some just read on, some have dots or lines that indicate it’s building pressure. During this time, you may see or hear steam coming from the float valve while the pressure is building.

Eventually, the steam will build up enough pressure to push the float valve up, which will seal the lid. The timer will start to count down as soon as the machine reaches full pressure inside the cooking pot.

Releasing the Pressure

When the cook time ends, turn off your pressure cooker.

Now we’re ready to release the pressure. You can choose to do nothing and let the pressure release on its own. This is called a natural pressure release, and it’s pretty anticlimactic. Just walk away until you hear the float valve drop and you can unlock the lid.

However, I’d recommend trying out the quick pressure release. On this step, it is SO important to keep your arms, hands, and face away from the valve—the steam is very hot and can burn. You can use a wooden spoon to turn the valve if you’re nervous.

To do a quick pressure release, carefully turn the pressure release switch to the Venting position so that the steam can escape. 

  • Instant Pot Duo: Turn the pressure release handle from Sealing (triple-S icon) to Venting (steam icon).
  • Ninja Foodi: Turn the pressure release valve from Seal to Vent.
  • Crockpot Express: Turn the steam release valve from the Closed/Seal position (X over the steam icon) to the Open/Release position (steam icon).
  • Power Pressure Cooker XL: Turn the pressure valve from the Lock position (bulls-eye icon) to the Open position (steam icon).

As soon as you turn the switch, you’ll see and hear a loud jet of steam coming from the pressure release switch.

Once the steam is completely dispersed, you should hear the float valve drop. When this happens, the lid unlocks. Carefully remove the lid, tilting it so that the steam vents away from you. The metal parts of the lid will be hot and may have hot droplets of water. Be sure to place the lid somewhere safe.

Use hot pads or silicone mitts to remove the cooking pot to cool.
