E5 error appears during pressure cooking; unit may stop heating and release steam.

Safety: Do not attempt to open the lid while the cooker is under pressure. Allow it to depressurize naturally or via the steam release valve as per the manual.

Steps:

• Depressurize safely: Turn the steam release valve to the venting position using a utensil to avoid steam burns. Wait until all steam is released and the float valve drops.
• Clean steam path: Remove the steam release valve, float valve, and anti‑block shield from the lid. Wash them in warm soapy water, removing any starch or food buildup. Ensure all small holes are clear.
• Inspect sealing ring: Check the silicone sealing ring for deformation, cracks, or food stuck in the groove. A damaged ring can cause erratic pressure behavior; replace if needed.
• Check float valve movement: Ensure the float valve moves freely up and down and is not jammed by dried food.
• Test with water only: Reassemble and run a short pressure cycle with only water. If E5 recurs, the pressure sensor or control PCB may be misreading and require replacement.

Warning: Never block or modify the steam release valve. Overpressure can be dangerous.
