E5 error code appears and the cooker will not build pressure or complete the cycle.

Safety first: Unplug the cooker and allow it to cool. Avoid touching hot steam areas.

• Check lid gasket: Remove the silicone lid gasket from the inner lid. Inspect for cracks, warping, or food buildup. Wash thoroughly and reinstall, ensuring it is fully seated in the groove.
• Verify valve position: Ensure the steam release valve is in the Seal position (not Vent) when starting a pressure program.
• Inspect for steam leaks: During a test run with water, watch for continuous steam escaping around the lid, from the float valve, or from the release valve. Persistent leaking indicates a bad gasket or valve seal.
• Clean float valve and cap: Remove the float valve and silicone cap (if removable). Clean both and reinstall. A stuck float can prevent proper pressure buildup.
• Advanced: If the cooker heats but never reaches pressure and E5 appears even with a new gasket and clean valves, the pressure sensor may be out of calibration and require replacement.
