How to Fix / Troubleshooting
Safety: Always unplug the unit before inspecting the power connections. Do not bypass fuses or safety devices.
- Check outlet: Verify the wall outlet voltage is within specification using a multimeter or by testing another appliance. Avoid using extension cords.
- Inspect power cord: Look for cuts, kinks, or burn marks. Ensure the plug fits firmly in the outlet.
- Access main PCB: Remove the rear lower panel and inspect the input terminals and fuse on the control board. Replace a blown fuse only with the same rating and investigate the cause of failure.
- Look for shorts: Check wiring harnesses for pinched or exposed wires that could short to the chassis.
- Replace PCB: If the power supply section of the board is visibly damaged or E9 persists despite stable mains and intact wiring, replace the main control board.
