How to Fix / Troubleshooting
Safety: Disconnect power before any disassembly.
- Basic reset: Unplug the cooker for 10–15 minutes, then reconnect and try a simple program like "Keep Warm" or "Reheat".
- Check lid and pot: Ensure the inner pot is installed correctly and the lid is fully closed and locked.
- Inspect internal connectors: Remove the outer housing as needed and reseat all connectors: bottom NTC sensor, lid sensor, pressure sensor, heating element, and control panel ribbon.
- Check for trapped moisture: If the cooker was recently washed or exposed to steam inside the housing, allow it to dry completely for 24 hours before retesting.
If the generic error remains after these steps, a detailed diagnosis of the main control PCB and sensors is required; replacement of the main PCB is often the most practical solution.
