Why does my Instant Pot IP-DUO80 display 'noPr'?
- BBeth HarrisonSep 10, 2025
The 'noPr' message appears because the working pressure wasn't reached during the pre-heating cycle. If the lid is leaking steam, refer to problems 3, 4, 5, and 6 for solutions. If there are no steam leaks and you're cooking frozen food, try running the current program again.
