OvHt
Instant Pot Pressure Cooker
Severity: ModerateWhat Does This Error Mean?

Frequently Asked Questions
Does OvHt mean my Instant Pot is broken?
Not necessarily. OvHt is a protective shutdown, not a hardware failure. If the error clears after cooling and the unit functions normally, the cause was environmental — not enough liquid or poor ventilation. Only repeated OvHt with correct liquid levels suggests a sensor fault.
Can I reset OvHt by unplugging?
Yes. Unplugging for 10 minutes resets the thermal sensor. Before plugging back in, make sure the root cause has been addressed — add liquid, clean the valve, and ensure good airflow around the unit.
