How to Fix / Troubleshooting

Safety first: Unplug the spa before opening any covers.

  • Extended power reset: Disconnect power for at least 30 minutes to fully reset the electronics.
  • Stable power source: Avoid sharing the circuit with devices that cause electrical noise (e.g., welders, large motors).
  • Inspect internal connectors: If allowed, open the control housing and gently reseat all plug-in connectors on the PCB.

If E14 recurs frequently, the control board firmware or hardware is likely compromised. Replacement of the main PCB or entire control unit is recommended via an authorized service center.
