Pressure cooker error codes
Instant Pot messages like Burn, Lid and NoPr are usually about the food, the liquid or the lid, not a broken pot. The C codes that point at a faulty sensor are a different story.
Every Instant Pot code
Each code opens its own page with the maker's checks and a verdict.
Burn Too hot at the bottom of the pot
The bottom of the inner pot got too hot, so the cooker cut the heat to stop the food burning.
C1 Faulty sensor
The cooker has found a fault with one of its sensors.
C2 Faulty sensor
Like C1 and C6, Instant's manuals list C2 simply as a faulty sensor, with no home fix.
C5 Too hot: no inner pot or no liquid
The base got too hot, either because the inner pot isn't in the cooker or because there's no liquid in it.
C6 Faulty sensor
The cooker has found a fault with one of its sensors.
C7 Heating element or not enough liquid
The cooker couldn't heat as expected.
C8 Wrong inner pot
The cooker has detected the wrong inner pot.
NoPr Not coming up to pressure
The cooker couldn't build pressure.
Lid Lid not in the right position
The lid isn't where the chosen programme needs it: not closed for pressure cooking, or on the pot during Sauté.
