Instant Pot Says "Burn" or Won't Come to Pressure
Two issues account for the vast majority of Instant Pot frustration: the "Burn" message, and a pot that never comes to pressure. Both are easy to fix once you know the cause.
The "Burn" Message
Burn means the bottom of the pot got too hot — the sensor detected scorching. Causes: not enough thin liquid (you need at least 1 to 1.5 cups), food or thick sauce stuck to the bottom, or a dairy/tomato/thickener layer that scorches. Cancel, release pressure, and check the bottom for stuck food.
Fixing and Preventing Burn
Deglaze the pot — add liquid and scrape every bit off the bottom with a wooden spoon before pressurizing. Layer thick sauces on TOP and do not stir them in. Make sure the inner pot sits flat on the element and the element/sensor area is clean and dry.
Won't Come to Pressure: Check the Sealing Ring
The silicone sealing ring must be seated all the way around the lid rim. A ring that is warped, torn, or not fully seated lets steam escape so it never pressurizes. Reseat it; replace it every 12-18 months (and keep a spare — rings absorb odors).
Won't Seal: Valve and Liquid
Set the steam-release valve to "Sealing," not "Venting" — the most common mistake. Confirm the float valve is clean and can rise. And make sure there is enough liquid; with too little, the pot cannot build steam.

FAQ
Food or thick sauce stuck to the bottom, or not enough thin liquid. Deglaze the bottom, add at least a cup of liquid, and layer thick sauces on top without stirring them in.
Usually the steam valve is set to Venting instead of Sealing, the sealing ring is not seated or is worn, or there is too little liquid. Check those three.
