Steam escapes continuously from the safety valve even at rest, not just during cooking.

Safety first: Never block the safety valve. Allow the cooker to cool and depressurize before servicing.

Step-by-step checks:

• 1. Clean valve seat: Remove the safety valve (if user-removable) and clean both the valve and seat thoroughly.
• 2. Inspect gasket: Check the rubber gasket for cracks or flattening. Replace if damaged.
• 3. Check spring tension: If the valve uses a spring, ensure it still provides firm closing pressure. Replace the valve assembly if weak.
• 4. Inspect lid surface: Ensure the area around the valve seat is not warped or cracked.

Note: Always use a genuine Saturn safety valve; incorrect valves can be dangerous.
