E7 appears and the cooker will not enter or maintain pressure; may beep repeatedly and cancel the program.

Safety first: If E7 appears during cooking, unplug the unit and allow it to depressurize naturally. Do not force the lid open.

• Inspect and clean pressure components: Once fully depressurized and cool, remove the steam release valve, anti-block shield, and float valve. Clean all parts thoroughly, removing any food, starch, or mineral deposits. Ensure the float valve moves freely up and down.
• Check sealing ring: Remove the silicone sealing ring from the lid, wash it, and inspect for deformation, cracks, or food trapped in the groove. Reinstall it evenly and firmly.
• Verify correct valve position: Ensure the steam release valve is set to the correct position for pressure cooking (usually "Seal" or similar). An incorrect position can confuse pressure readings.
• Test with water only: Add 2–3 cups of water, close the lid, set the valve to seal, and run a short pressure program. Observe whether the float rises and if E7 reoccurs.
• Sensor/board issues: If all mechanical parts are clean and moving freely but E7 persists, the pressure sensor or control board may be faulty and require replacement.

Warning: Never attempt to defeat or block the safety valves to avoid E7. This can create a dangerous overpressure condition.
