E7 appears during preheat or pressure build and the cooker aborts the program.

Safety first: Do not move or force open the cooker if it may be under pressure. Unplug the unit.

• Allow natural cool-down: Let the cooker sit until the float valve drops and the lid unlocks normally.
• Inspect fill level: Ensure you are not exceeding the MAX line, especially with beans, grains, or foamy foods. Reduce volume for these recipes.
• Clean steam components: Remove the steam release valve, anti-block shield, and float valve. Clean all parts thoroughly to remove starch buildup or food particles.
• Check valve movement: Confirm the steam release valve can move freely between sealing and venting positions and is not gummed up with residue.
• Retry with water: Run a pressure test with only water to confirm that E7 does not recur under normal conditions.

If E7 occurs even with water-only tests and clean components, the pressure sensor or control logic may be misreading pressure and should be evaluated by a technician.
