Possible Causes
Steam release handle not in correct position, Blocked steam release valve, Faulty steam release position sensor (if equipped)
How to Fix / Troubleshooting
Safety first: Ensure the cooker is fully depressurized before touching the steam release components. Use a utensil to move the handle if hot.
- Check handle position: Verify the steam release handle is set to the correct position (SEAL or VENT) as required by the program.
- Clean valve: Remove the steam release valve and cap. Clean thoroughly to remove starch or food buildup. Ensure the valve moves freely.
- Inspect sensor: On models with a position sensor, access the top housing and check the steam release position switch or magnet. Adjust or replace if it does not change state when the handle is moved.
