why does my cosori pressure cooker keep showing the 'Food burn' error code?

Diagnosis

The "Food Burn" error (often displayed as "burn" or "burn food") on your Cosori Pressure Cooker is a safety feature. It triggers when the cooker's internal sensor detects the bottom of the inner pot is overheating, which usually happens before food actually scorches. The primary causes are: 1) Insufficient liquid or thin sauces that evaporate or get absorbed too quickly. 2) Thick, starchy, or dense foods (like tomato sauce, oatmeal, beans, or thick stews) settling and sticking to the pot bottom, creating a barrier that causes hot spots. 3) A blocked or stuck float valve preventing the pot from sealing and pressurizing correctly, which alters the cooking process.

How to Fix It

1. Immediately turn off and unplug the cooker. Carefully perform a Quick Pressure Release following the manufacturer's safety instructions.
2. Once safe, open the lid. Check if the food is dry or stuck. For soups and stews, add at least 1 cup of warm liquid (water or broth) and stir thoroughly, scraping the bottom to loosen any residue.
3. For problematic foods, use the "Saute" function to thin sauces before pressure cooking, or layer ingredients: pour liquids in first, then add dense foods on top without stirring.
4. Ensure the inner pot is correctly seated and that the silicone sealing ring is properly installed and clean. Verify the float valve moves freely and is clean.
5. Restart cooking, typically using a gentler setting like "Slow Cook" if the error persists, or manually set a lower pressure.

If That Didn't Work

If the error recurs consistently, even with adequate liquid and proper technique, there may be a sensor issue or mineral scale buildup on the heating element. Descale the entire cooker, including the heating plate, with a vinegar solution. For persistent sensor errors, contact Cosori customer support, as the unit may require inspection or replacement.

Heads Up

Never ignore this error or try to continue cooking without addressing it, as it can lead to ruined food, damage to the non-stick coating of the inner pot, or in rare cases, a safety hazard from excessive heat buildup. Always allow the pot to cool before cleaning.
