Possible Causes
Faulty temperature sensor reading low, Pressure not fully achieved due to minor leaks, Incorrect altitude settings (if available), Weak heating element
How to Fix / Troubleshooting
Safety first: Verify food safety by ensuring meats reach safe internal temperatures.
- Check for leaks: Observe during cooking for small steam leaks around the lid or valve. Replace sealing ring or valve gaskets if needed.
- Run water test: Time how long it takes to reach pressure with 2–3 cups of water. Excessive time may indicate weak heating or leaks.
- Adjust recipes: Increase cook time slightly to compensate while diagnosing hardware.
- Inspect sensors and heater: Test the bottom NTC sensor and heating element for proper resistance. Replace any component out of spec.
