How to Fix / Troubleshooting
Safety: Unplug the unit. Power supply components can store charge; avoid touching capacitors.
- Check power source: Verify the outlet voltage is stable and within specification using another appliance or a meter.
- Inspect power cord: Look for cuts, kinks, or burn marks on the Pevino power cord. Replace if damaged.
- Check mains connections: Remove the rear panel and inspect the mains input block and wiring to the main control board. Tighten any loose screws and reseat connectors.
- Board inspection: Examine the main control board for burnt components, cracked solder joints, or bulging capacitors in the power supply area.
- Replace main board: If the E9 persists and no external wiring issues are found, replace the main control board with an exact Pevino part number match.
