How to Fix / Troubleshooting
Safety First: Unplug the pump before any inspection.
- Power reset: Unplug the pump for at least 5 minutes to allow capacitors to discharge. Plug back in and attempt to restart.
- Surge protection: If the error appeared after a storm or power outage, connect the pump to a surge-protected outlet to prevent further damage.
- Inspect housing: Check for burn marks or melted plastic around the control area. If present, discontinue use immediately.
- Service or replace: If E9 remains after a full power reset and there are no external wiring issues, the control PCB is likely damaged and should be replaced as a complete assembly.
