How to Fix / Troubleshooting
Safety first: Allow the cooker to depressurize fully before inspection. Unplug from power.
- Clean pressure path: Remove and clean the steam release valve and anti-block shield. Ensure the steam path from the pot to the sensor is not obstructed.
- Check gasket and float: Inspect the lid gasket and float valve for proper movement and sealing.
- Test with water only: Run a short pressure cycle with only water to see if C2 reappears.
- Sensor inspection (advanced): Access the pressure sensor (often mounted on the main PCB with a small hose or port). Ensure the hose is not kinked and the connector is secure.
