I'm sorry to hear that you're missing the manual for your Savourex Pro Line Pressure Cooker/Insta Pot. Since it's an off-brand model, finding specific instructions or resources for that exact model may be challenging. However, I can provide you with some general guidance on how to use a pressure cooker, which should be applicable to your device as well.
Here's a step-by-step guide on using a pressure cooker:
1. Read the safety precautions: Before you begin using the pressure cooker, it's essential to familiarize yourself with the safety precautions mentioned in the manual. This will help you operate the appliance safely.
2. Prepare the ingredients: Start by preparing the ingredients for your recipe. Whether you're cooking meat, vegetables, grains, or soups, ensure that everything is properly washed, chopped, and ready to be cooked.
3. Add ingredients and liquid: Place the ingredients into the pressure cooker pot. Most pressure cooker recipes require a minimum amount of liquid (such as water, broth, or sauce) to create steam and build pressure. Follow the recipe guidelines for the appropriate amount of liquid.
4. Close the lid: Ensure the pressure cooker lid is securely closed. Some models may have a locking mechanism or an indicator to confirm that the lid is properly sealed.
5. Set the pressure release valve: Pressure cookers typically have a pressure release valve that controls the pressure level. Refer to your specific model's instructions to determine how to set the valve for cooking.
6. Select the cooking time and pressure level: Depending on your recipe, you'll need to set the desired cooking time and pressure level. Most pressure cookers have preset cooking programs for different types of food. Alternatively, you may need to manually set the time and pressure.
7. Start cooking: Once you've set the cooking time and pressure, start the cooking process. The pressure cooker will heat up and build pressure inside the pot. The cooking time will begin once the desired pressure is reached.
8. Natural or quick release: After the cooking time is complete, you have two options for releasing the pressure: natural release or quick release. Natural release involves letting the pressure decrease naturally over time, while quick release involves manually venting the pressure using the release valve. Refer to your pressure cooker's instructions to determine the appropriate method for your recipe.
9. Open the lid: Once the pressure is fully released, and it is safe to do so, you can open the lid. Be cautious of the hot steam that may escape when opening the cooker.
It's important to note that these are general instructions for pressure cookers. Your specific model may have additional features or variations, so it's always a good idea to consult the manual if you can find one or reach out to the manufacturer for support.

Apparently the Cooks kitchen appliances are sold (new) exclusively by J. C. Penney. I still have not found a replacement lid for your pressure cooker. I suggest you call J. C. Penney Customer Service: 800-322-1189. Ask about the availability of a replacement lid for your pressure cooker.

Hello -

So you need to find and purchase a replacement lid for your pressure cooker. That pressure valve which broke off the lid is VERY IMPORTANT.

Do you perhaps mean it is a Cook's Essentials pressure cooker? Cook's Essentials cookware (new) is sold exclusively by QVC.

First, check the user manual for your pressure cooker. It may contain a phone number or web address for replacement parts or service.

If you have no manual or there is no information on a source for replacement parts or repair service, and if I am correct in thinking yours is a Cook's Essentials pressure cooker, then, I recommend you contact QVC Customer Service and ask about the availability of a replacement lid for your pressure cooker. This is the link to QVC Customer Service:

The company had a major recall and went out of business. No manuals appear to be available on the web.
Here are some general instructions you can use:

1 Set up your cooker. Place your Ultrex Pressure Cooker on the stove. Remove the lid and pour in no more than 2 inches of water. Depending on what you are cooking the amount of water will vary. More water will ultimately cook larger amounts of food, but you will need to refer to your specific model's instructions on this matter.

2 Put in the food you wish to cook. Close and lock the lid firm to the pot. Make sure it is locked securely so none of contents boil out of the top.

3 Turn on your burner to high heat for approximately ten minutes. Allow the water to boil.

4 Turn the stove down to a low setting after the water is boiling in the cooker. Flip the pressure valve closed and allow your food to simmer.

Set the pressure valve to ten pounds. For vegetables, cook 30 to 45 minutes. For meats, cook 45 to 60 minutes.5

6 Open the pressure valve and allow the pressure to discharge. Unlock and remove the lid to find your fully cooked meal.

Not sure which type of Tefal rice cooker you have received.
You may want to go to the Tefal website and pick the manual for the one that could be your model.

Though there is not much to it if you are cooking rice. Take the pot out and wash it as any metal utensil. Put as many cups of rice you want to cook in a separate bowl using the measure that would have come with it. Otherwise take a 150ml measure. Wash it the rice thoroughly with water and drop it into the pot. Fill water to the level of number of the cups you have put in. Wipe the pot dry from outside and place in the cooker jacket. Put lid on. Turn the power on and press the Cook button. Once rice is cooked it will switch to keep warm and leave it there for about 5 minutes before you use the cooked rice.

When the cooker is reaching pressure, the valve should point to the dot, and after pressure cooking, you turn the valve towards release. The valve will feel quite loose, but it if it's in the wrong position when the cooker is reaching pressure then the cooker cannot build, and consequently will not release, pressure.

Here is the manual if you need more information on how to operate the cooker:

The rice cooker lid has to be closed and the dial knob has to be in the lock position (turing on the pressure lamp) before cooking can start. There are two tiny wires sending signal to the main controller to indicate that the cooker is in lock position. The wires are vey tiny and they can break over the years as a result of opening and closing the lid many times. When these wires are broken, the main controller cannot detect the lock position and will give E01 Error.
