Found these troubleshooting notes for an Instant Pot. People tends to lump two completely differently problems together under the "buttons not working" issue. Thought I'd bring it up for discussions since it comes up so often.
If ALL the buttons on the IP are unresponsive, it's the main PCB or the display module. Pop the housings and look for any burn mark on the PCBs. If found, replace the main controller (or the display module). If not, the buttons is OK.
Only the pressure cook button is broken. The pressure cook button is NOT a button. If the IP cannot build enough pressure to cook, it will not begin the cooking cycle. Fix the pressure seal/leak and it should work. Again, the unit is not broken, it's just following the build-in safety protocols.
How many of these instances have there been where the PCB has failed versus the pressure seal failing?
