How to Fix / Troubleshooting
Safety: Disconnect power before accessing any internal components.
- Extended power reset: Unplug the unit for at least 30 minutes to fully discharge internal capacitors. Plug back in and test.
- Surge protection: If E9 occurred after a storm or power event, connect the unit through a properly rated surge protector to prevent future damage.
- Factory reset: If the user manual describes a factory reset key combination, perform it to reload default settings.
- Visual inspection: Remove the front panel and inspect the main PCB for burn marks, cracked components, or bulging capacitors. If present, the board must be replaced.
- Board replacement: EEPROM or firmware issues are not field-repairable. Replace the main control board with the exact Black+Decker part. This is typically a technician-level repair.
