Multicooker shows E6 and will not start or aborts pressure programs during preheating.

Safety first: Unplug the cooker and ensure it is fully depressurized and cool.

Basic checks:

• Clean lid and valves: As with E5, ensure the steam release and safety valves are clean and moving freely. A stuck valve can cause abnormal pressure readings.
• Dry the unit: If the cooker was recently washed or exposed to steam around the control panel, allow it to dry for several hours unplugged.
• Check for error on non-pressure modes: Try a non-pressure program (e.g., bake or sauté). If E6 appears even without pressure, the pressure sensor circuit is likely faulty.

Advanced (for technicians): The pressure sensor is usually mounted on the main PCB or connected via a small silicone hose. Inspect for cracks in the hose and reseat the connector. Replacement of the sensor or PCB should be done by a service professional.
