A BAD RECIPE
A lot of bloggers and cooks are inexperienced at using their Instant Pots. This has produced some recipes that haven't been tested as thoroughly as they should be.
TYPES OF INGREDIENTS
Take a look at what type of ingredients you were using. Some ingredients do not perform as well under pressure as others.
A STICKY FOND
This is the layer that might be created on the bottom of your Instant Pot liner after you brown or saute something. It's a small layer of caramelization that is created from the natural sugars in your food being exposed to high heat.
A NON-PERFORMING SEAL
The seal is the part of the Instant Pot lid that keeps the steam from escaping the pot. This allows pressure to build for cooking. However, there are a few things that might cause your sealing ring from performing correctly.
ISSUES WITH YOUR FLOAT VALVE
The float valve is the little button that raises and lowers to indicate whether your Instant Pot is currently under pressure. If it is not raising, the Instant Pot will give the Burn notification. This is a safety measure.
