How to Fix / Troubleshooting
Safety: Turn off power at the GFCI before unplugging the topside panel.
- Step 1 – Inspect cable: Remove the topside panel bezel and gently pull the ribbon cable. Check for corrosion, kinks, or cuts. Reseat both ends at the panel and control pack.
- Step 2 – Dry moisture: If condensation or water is present under the topside overlay, dry the area thoroughly. Persistent moisture usually requires panel replacement.
- Step 3 – Substitute panel: If available, test with a known-good Vita Spa topside panel to determine whether the fault is in the panel or the control pack.
