E7 appears on the display, often accompanied by no heating or erratic temperature control.

Safety first: Unplug the cooker and ensure it is cool before handling the lid or internal wiring.

• Clean lid components: Remove the lid and clean around any visible sensor housings, especially near the steam vent and inner lid plate. Food buildup can affect sensor readings.
• Inspect lid wiring (if applicable): On models with a wired lid, check the flexible cable or connector between lid and body. Look for kinks, cuts, or exposed conductors.
• Check connectors: Open the base and locate the lid sensor connector on the main PCB. Reseat the connector and inspect for corrosion or bent pins.
• Test operation: After reassembly, plug in and try a non-pressure mode. If E7 appears immediately, the sensor or board is likely defective.
• Replacement: Replace the lid temperature sensor or complete lid assembly if the sensor is integrated. If replacing the lid does not resolve E7, the main control board may require replacement by a technician.
