E5 error appears during pressure build-up; cooker stops and may release steam prematurely.

Safety first: Do not attempt to open the lid until all pressure is released and the float valve has dropped. Unplug the unit.

• Check fill level: Ensure you are not exceeding the maximum fill line, especially with beans, grains, or foamy foods. Reduce quantity and retry.
• Clean steam release valve: Remove the steam release knob/cap and wash it thoroughly. Ensure the vent hole is clear.
• Inspect safety valve: Locate the secondary safety valve on the lid (often a small metal or silicone plug). Make sure it moves freely and is not blocked by dried food.
• Clean lid interior: Remove the inner lid plate (if removable) and clean all channels and holes with warm soapy water. Rinse and dry completely.
• Check gasket: Inspect the main silicone sealing ring for deformation or food buildup. Clean or replace if worn.
• If E5 continues with proper fill and clean valves, the pressure control system (valves and sensor) may need professional inspection to ensure safe operation.
