Possible Causes
Steam leak from sealing ring, Steam release valve not fully closed, Cracked lid or lid plate, Faulty float valve seal
How to Fix / Troubleshooting
Safety first: Allow the cooker to depressurize naturally or via the valve before opening.
- Observe for leaks: During a test run with water, watch for continuous steam escaping around the lid or valve.
- Replace sealing ring: If steam leaks around the lid circumference, install a new genuine Tefal sealing ring.
- Check float valve: Remove and clean the float valve and its silicone cap. Replace the cap if hardened or cracked.
- Inspect lid plate: Look for cracks or warping in the inner lid plate. Replace the lid assembly if damaged.
- Re-test: Run another pressure cycle with water only. If P1 still appears, the pressure sensor or control board may be misinterpreting pressure changes.
