How to Fix / Troubleshooting

Safety first: Disconnect power before accessing internal wiring.

Step-by-step checks:

1. Re-seat connectors: Remove the bottom cover and, if needed, the top cover to access all sensor connectors (lid switch, pressure sensor, NTC). Unplug and replug each connector to wipe oxidation from contacts.
2. Inspect harness routing: Check the flexible harness that runs through the lid hinge area. Look for pinched, cut, or broken wires caused by repeated lid movement.
3. Check for moisture: Look for signs of condensation or liquid ingress around the control board and connectors. Dry gently with a hairdryer on low (no overheating) and allow to sit before reassembly.
4. Test operation: After reassembly, run a simple program and gently move the lid to see if E9 reappears. If movement triggers the error, the harness is likely damaged internally.

Note: If wiring and connectors are intact, the fault may be on the main PCB, requiring board replacement.

E9 appears intermittently; cooker may stop mid-cycle and reset.
