E7 error appears intermittently; cooker may overheat or underheat.

Safety first: Unplug the cooker and allow it to cool. Do not immerse the lid in water unless the manual explicitly allows it.

• Inspect lid underside: Open the lid and examine the underside where the temperature sensor is located (often near the steam vent). Check for cracks, corrosion, or burnt spots.
• Clean gently: Wipe the sensor area with a slightly damp cloth to remove grease or residue. Avoid soaking the sensor or letting water enter the lid.
• Check hinge area: Move the lid slowly and look for pinched or frayed wires near the hinge where the lid harness passes into the body.
• Dry thoroughly: If the lid was recently washed, let it air dry completely for several hours before reuse to ensure no moisture is shorting the sensor.
• Test: Plug the unit back in and run a non-pressure program to see if E7 reoccurs.

If E7 persists, the lid temperature sensor or lid harness likely needs replacement, which typically requires disassembling the lid and should be done by a service technician.
