Possible Causes
How to Fix / Troubleshooting
Safety first: Turn off power at the service panel before adjusting any wiring or settings.
Steps to check:
- Verify frequency and voltage: Confirm your local mains frequency (50/60 Hz) and voltage, and compare with the Jacuzzi pump nameplate.
- Check configuration switches: Open the control box and locate any dip switches or jumpers labeled for voltage/frequency. Set them according to the installation manual.
- Inspect line wiring: Ensure line and neutral (for 120V) or both hot legs (for 240V) are connected to the correct terminals as marked in the Jacuzzi wiring diagram.
- Disconnect automation: Temporarily disconnect any external automation or RS-485 control to see if the error clears when the pump is standalone.
If E07 persists with correct wiring and configuration, the control board may be misprogrammed or defective and require replacement.
