Sometimes, your Instant Pot may show a Burn signal. There are many reasons why you are getting it: The pot is too hot from sauteeing, should this happen in the future simply turn off the pot and wait a few minutes. It could be that the gasket in improperly inserted. Open the lid and fix it properly. The pressure relief valve could also be stuck and release steam. Check that. There are bits stuck to the bottom of the pot. Always give the ingredients a stir after adding water to prevent anything from sticking at the bottom. But don't mix after adding the salsa or tomato puree.
