How to Fix / Troubleshooting
Safety first: Unplug the cooker before opening any covers.
- Power cycle: Unplug the unit for at least 10 minutes to discharge internal capacitors. Plug back in and test a simple program.
- Check outlet: Plug the cooker into a different outlet, preferably on a different circuit, to rule out power issues. Avoid using extension cords or power strips.
- Inspect internal connectors (advanced): If out of warranty and qualified, remove the bottom or rear cover to access the main control board and display/control panel board. Reseat ribbon cables and multi-pin connectors.
- Look for damage: Examine the board for burnt components or corrosion. If present, the board must be replaced.
Persistent E9 errors usually require replacement of the main control board or display board. This is a complex repair best left to a technician.
