Possible Causes
Corrupted firmware on control PCB, Failed relay or driver on main board, Loose connector between display board and power board, Power surge damage
How to Fix / Troubleshooting
Safety: Disconnect from mains before any disassembly.
- Basic reset: Unplug the multicooker for at least 10 minutes. Plug into a different outlet (avoid power strips) and try again.
- Check for moisture: Inspect the control panel area for signs of condensation or liquid spills. If moisture is present, leave the unit unplugged in a dry, warm room for 24 hours before retrying.
- Inspect internal connectors (advanced): With the unit unplugged, remove the outer housing screws and carefully lift the top cover to access the control PCB and display PCB. Reseat all ribbon cables and plug connectors firmly.
- Look for burn marks: Examine the control board for burnt components, cracked solder joints, or bulging capacitors. If found, the board should be replaced, not repaired at home.
- Conclusion: E6 usually indicates a board-level fault. If reseating connectors and drying do not resolve it, replace the main control PCB with a ProfiCook-compatible spare or contact an authorized service center.
