E8 error appears during pressure cooking; unit may not reach or maintain set pressure.

Safety first: Allow the cooker to fully depressurize and cool before inspection.

• Clean pressure path: Remove and clean the steam release valve, anti-block shield, and any removable pressure channels in the lid. Blockages can cause abnormal pressure readings.
• Check lid seal: Inspect the silicone lid gasket for deformation, cracks, or food buildup. A poor seal can cause unstable pressure and confuse the sensor. Clean or replace the gasket as needed.
• Reset the unit: Unplug the cooker for 10 minutes to reset the control electronics. Plug back in and run a water-only pressure test.
• Observe behavior: If E8 appears even with clean components and water only, the pressure sensor or its circuitry is likely defective.
• Professional calibration/replacement: Pressure sensors on Wolf Gourmet multicookers are typically integrated with the control board and are not user-calibrated. Contact an authorized service center for board replacement.
