How to Fix / Troubleshooting
Safety: Unplug the cooker before further steps.
- 1. Power reset: Unplug for 10–15 minutes, then reconnect and test with a simple program.
- 2. Drying period: If the cooker was exposed to heavy steam or liquid spills, allow it to dry for 24–48 hours in a dry environment.
- 3. Test multiple modes: Try Saute, Slow Cook, and Pressure Cook. If E12 appears across modes, suspect internal electronics.
- 4. Professional inspection: A technician can open the housing, reseat internal connectors, inspect for corrosion, and test the PCB. Replace the main control board if communication faults persist.
