Display shows SEAL or a gasket icon and the cooker struggles to reach or maintain pressure.

Safety first: Ensure the cooker is cool and depressurized before removing the lid.

• Verify gasket installation: Remove the silicone gasket and reinstall it firmly into the lid groove, ensuring it is not twisted.
• Inspect gasket condition: Look for cracks, flattening, or hard spots. Replace the gasket if it does not sit snugly or shows wear.
• Clean sealing surfaces: Wipe the lid rim and cooker body rim with a damp cloth to remove oil and food residue that can prevent sealing.
• Test with water: Run a short pressure cycle with only water to confirm that the SEAL message clears and pressure is maintained.
