What Does the "Burn" (or "OvHt") Warning Mean?
If you've seen "Burn," "OvHt," or a flame icon appear on your Instant Pot's display mid-cook, don't panic. This is a safety feature, not a failure. The Instant Pot's sensors detected that the bottom of the inner pot was getting too hot — usually because something is scorching on the heating element before enough steam pressure has built up.
Understanding why it happens makes it very easy to prevent in the future.
The Most Common Causes of the Burn Warning
1. Thick Sauces or Tomato Products Added Before Cooking
Tomato sauce, tomato paste, condensed soups, and thick BBQ sauces are the number one culprit. These thick liquids settle to the bottom, don't circulate well, and scorch before pressure builds. The fix: Always layer thick sauces on TOP of your other ingredients and do not stir them in before pressurizing.
2. Not Enough Liquid
The Instant Pot needs a minimum of about 1 cup of thin liquid (water or broth) to generate enough steam to pressurize. If you're short on liquid, the bottom overheats. The fix: Always ensure at least 1 cup of liquid is present, and make sure it's thin enough to create steam freely.
3. Food or Residue Stuck to the Bottom
If you used the Sauté function before pressure cooking, any browned bits stuck to the pot bottom can trigger the burn sensor. The fix: After sautéing, always deglaze by adding a splash of broth or wine and scraping the bottom with a wooden spoon before locking the lid.
4. Starchy Foods Without Enough Liquid
Pasta, rice, and other starchy foods thicken the liquid rapidly, causing it to stick. The fix: Use the recommended liquid ratios from tested recipes, and don't stir pasta into sauce before cooking.
What to Do When the Burn Warning Appears
- Don't open the lid immediately. Wait for the pressure to drop naturally or do a careful quick release first.
- Once pressure is released, open the lid and check the contents. Is anything actually burnt? Often the food is fine.
- Deglaze the pot: Remove the food temporarily, add ½ cup of broth or water, and scrape the bottom clean using a wooden spoon or silicone spatula.
- Reassemble: Layer ingredients properly (liquids on the bottom, thick sauces on top), then restart the cook.
- Reduce cook time slightly since the food may have partially cooked already.
How to Prevent the Burn Warning Every Time
- Always deglaze after using Sauté mode.
- Add thick/creamy sauces and dairy AFTER pressure cooking, not before.
- Ensure you have at least 1 cup of thin liquid before sealing.
- Don't overfill the pot — food should be below the max line.
- Keep your sealing ring clean and in good condition for proper pressurization.
Is Your Food Still Safe to Eat?
In most cases, yes. The burn warning is triggered early, before significant scorching occurs. The food in the center and top of the pot is typically fine. Check the bottom layer — if there's only minor browning, it's often edible; if something is truly burnt, discard just that portion.
Final Tip
The burn warning is actually a useful teacher. After experiencing it once or twice and applying these fixes, most Instant Pot users never see it again. It's all about layering your ingredients correctly and ensuring enough thin liquid is present.
