E6 appears on the display and the cooker does not heat or stops mid-cycle.

Safety first: Unplug the appliance and let it cool. Do not open the lid if under pressure.

• Visual inspection: Open the lid and inspect the inner stainless-steel lid plate. Look for signs of water ingress around the sensor area (often a small bump or screw in the center).
• Clean and dry: Wipe condensation from the inner lid and hinge area. Allow the cooker to air dry for several hours with the lid open.
• Check lid movement: Gently move the lid through its full range to ensure the hinge cable (if visible) is not pinched or damaged.
• Reset test: After drying, plug in and run a non-pressure program (e.g., sauté) with the lid open if the model allows. If E6 appears immediately, the lid sensor circuit is likely defective.
• Repair: The lid temperature sensor or complete lid assembly may need replacement. This involves disassembling the lid and dealing with wiring; recommended for professional service.
