E8 error appears during pressure cooking; cooker may overheat or fail to regulate temperature correctly.

Safety: Do not attempt to open the lid while the unit is under pressure. Allow full natural release if unsure.

• Clean steam valve: Remove the steam release valve and anti‑block shield. Soak in warm soapy water and clear any food particles from the small holes.
• Check float valve: Ensure the float valve moves freely up and down. Clean around the valve seat and replace the small silicone gasket if worn or deformed.
• Inspect safety valve: Examine the secondary safety valve on the lid for signs of clogging or corrosion. Replace if it does not move freely or appears damaged.
• Test with water only: After cleaning, run a short pressure program with only water to verify normal pressure build and release.
• Replace components: If E8 persists, replace the steam release valve assembly and float valve kit. If the mechanical parts are new and the error remains, the pressure sensor/control PCB may require replacement.
