Is the Instant Pot® Sealing Ring safe?
The Instant Pot® sealing rings pass UL, FDA and LFGB tests for safety, including food safety. The Instant Pot® sealing ring is an integral part of the Instant Pot® safety features. The sealing rings have been designed, engineered, and built with the optimal material to achieve the hardness and strength required to withstand high-pressure force during electric pressure-cooking.
How do I remove the food odor from the Sealing Ring?
The Instant Pot® sealing ring is made from food grade silicone. Silicone may pick up food odors during cooking. To remove the odor, try the following:
Steam Clean – add 2 cups of water or white vinegar and cut-up lemon rind, run the Steam program for 2 minutes with the sealing ring in position. Then, allow the sealing ring to air dry.
Place the sealing ring in the dishwasher. High temperature and strong detergent will usually remove the majority of smells.
Soak the sealing ring overnight in white vinegar, lemon juice, tomato juice, or bleach. Then, run it through the dishwasher.
Store the sealing ring in a plastic bag with ground coffee or baking soda.
Or, you may wish to have one sealing ring for savory and another for sweet foods.
How often should the Sealing Ring be cleaned?
It is not necessary to remove the sealing ring after each use. One should remove the sealing ring and clean following every 5-6 uses or if preparing foods that splatter.
How often should the Sealing Ring be replaced?
The sealing ring is made from food grade silicone and is extremely durable. Under normal conditions it should be fine for 18 – 24 months. If you notice cracks, leaking or deformation in the sealing ring, it should be replaced. However, the sealing ring is porous and may absorb odors and become discolored. To avoid discoloration and odors, one may wish to change the sealing ring every 6 – 12 months.
Can I use a different brand of Sealing Ring?
Unapproved and unauthorized sealing rings are not manufactured, tested or certified by Instant Pot®; as such, we are unable to confirm if they meet Instant Pot® established standards. The use of third party sealing rings may have unexpected effects on your Duo Plus, and will void the Instant Pot® warranty. Instant Pot® recommends only using Instant Pot® branded sealing rings.

How much liquid is required in the inner pot to Pressure Cook?
To pressure cook always add at least 1.5 – 2.5 cups / 355 – 473 ml (depending on quart size) of water or other liquids with a thin, watery consistency so enough steam can be generated to cook under pressure. These liquids include cooking sauces, wine, beer, and stocks.
Note: Oils and oil-based sauces do not have sufficient water content and do not account for the required liquid volume.
Pressure is not building why?
To build pressure it requires at least 1.5 – 2 cups (355 – 473 ml) of water or liquid.
Note: The amount of liquid is dependent on the quart size.
Not setting the steam release valve/handle to the Sealing position for pressure cook and steam. If it is not Sealed pressure will not build. For additional troubleshooting: https://instantpot.com/troubleshooting/
Are there any foods one must be cautious, or cannot be prepared in the Instant Pot®?
Yes, we recommend caution with foods such as applesauce, cranberries, pearl barley, oatmeal or other cereals, split peas, noodles, macaroni, rhubarb or spaghetti as they can foam, froth or sputter and can clog the anti-block shield, steam release valve/handle, float valve or steam release pipe. When preparing these types of food the inner pot should not be more than ½ full and a trusted recipe should be followed.
Note: Regular cleaning of the Steam Release Valve/handle, Float Valve and Anti-Block Shield is important to avid food debris from interfering with their function.
What do I do if the Float Valve is stuck during de-pressurization?
Move the Steam ReleaseValve/handle to the Venting position. Once all the steam is released, push the float valve down with a pen or long stick.
The float valve has not risen, why is pressure not building?
To build pressure please ensure your Instant Pot® has the necessary amount of water or liquid;
Note: Regular cleaning of the Steam Release Valve, Float Valve and Anti-Block Shield is important avoid any food debris from interfering with their function.
What does “Ov Ht” mean?
Instant Pot® is built with a burn-protection mechanism. When a high temperature 140C/ 284F is detected on the bottom of the inner pot, the burn-protection mechanism suspends heating to avoid food burning. This is reflected by the code “Ov Ht”.
The only exception to the burn-protection mechanism is with food that has a very high starch content. For instance, if you add flour in your chili, the flour will sink to the bottom, solidifies at low temperatures and can block heat dissipation. In this situation, we suggest you add flour to the chili after initial cooking and perhaps cooking it for an additional one to five minutes to allow thickening of the chili.
How do I know when it is Safe to open the lid?
Start by pressing Cancel. The LCD will display OFF. Before opening the lid, make sure the float valve has dropped. Do not open the lid if the float valve has not dropped. Do not open the lid if it is locked and cannot be opened. Do not force the lid open at any time.
Note: When opening the lid, the inner pot may adhere to the lid. This is caused by vacuum due to cooling. To release the vacuum, move the stream release button to the Venting position.
Why is there an occasional clicking sound when using my Instant Pot®?
The clicking/cracking sounds in the Instant Pot® comes from the following possible sources:
Water or moisture on the bottom of the inner pot
Instant Pot® power switch turning on and off during operation
Friction between the lid and the housing created by expansion and contraction due to changing internal pressure and temperature
The flat flexible pressure board under the heating element bending under pressure (the board is designed to last over 100,000 uses)
Food such as dry beans popping open during cooking
Can I place the Instant Pot® on the stovetop while a burner is in use and/or close to a Heat source?
Do not place the cooker on or near a hot gas or electric burner, or in a heated-oven, as this will damage the cooker.
Note: Intended for countertop use only.
What accessories are recommended for use with Instant Pot®?
Instant Pot® recommends to only cook in the Instant Pot® stainless steel or ceramic non-stick inner pots for best results. Other brands may not have the correct curvature to match the heating element. Accessories and parts not branded Instant Pot® or recommended by Instant Pot® may cause the cooker to malfunction.
My Instant Pot® has stopped working, what do I do?
