Possible Causes
How to Fix / Troubleshooting
Safety first: Disconnect power before opening the control housing or handling internal connectors.
- Power reset: Unplug the spa for at least 10 minutes, then plug back in and check if E07 clears.
- Inspect control panel:
- Check the top control panel for visible cracks, water under the display, or stuck buttons.
- Dry the surface thoroughly and protect it from direct rain or splashing.
- Check cable connection (if accessible):
- Open the control housing only if allowed by the user manual.
- Locate the flat ribbon cable from the keypad to the PCB and ensure it is fully seated and not corroded.
If E07 persists, the keypad assembly or main control board may need replacement. This typically requires disassembling the sealed control unit and should be done by a qualified service center.
