Possible Causes
Blocked primary steam release path, Stuck or contaminated safety valve, Excessive food foaming blocking vent, Faulty pressure sensor over-reporting pressure
How to Fix / Troubleshooting
Safety first: Allow the cooker to depressurize naturally. Never cover or block the steam outlet.
- Clean all pressure components: Disassemble and clean the steam release valve, anti-block shield, float valve, and safety valve area thoroughly.
- Avoid overfilling: Ensure the food level does not exceed the maximum fill line, especially for foamy foods like beans or porridge.
- Test with water only: Run a pressure cycle with only water to verify normal operation. If P2 still appears, suspect a pressure sensor or control issue.
- Replace pressure sensor: Install a new Polaris pressure sensor module if overpressure is falsely detected.
