Possible Causes
Failed microcontroller on PCB, Power supply section fault on control board, Corrupted firmware, Shorted component on board (triac, regulator, capacitor)
How to Fix / Troubleshooting
Safety first: Unplug the multicooker before opening any covers. Electronic board work should be done by qualified persons.
- Power cycle: Disconnect power for 10–15 minutes to allow capacitors to discharge. Plug back in and test a simple program. If E6 returns immediately, the fault is likely persistent.
- Check for moisture: Inspect the control panel area for signs of liquid spills or condensation. Allow the unit to dry in a warm, dry place for 24 hours and retest.
- Visual PCB inspection (advanced): Remove the top control panel or bottom cover (depending on model) to access the main PCB. Look for burnt components, bulging capacitors, or cracked solder joints.
- Connector check: Ensure all harnesses (heater, sensor, pressure sensor, lid switch) are firmly seated. A shorted peripheral can sometimes trigger board errors.
- Board replacement: If no external cause is found and E6 persists, replace the main control board with a Gourmia-compatible PCB for your exact model. Transfer any wiring one connector at a time to avoid miswiring.
