How to Fix / Troubleshooting
Safety: Turn off power before opening the control pack. High voltage is present.
- Step 1 – Hard reset: Turn off the GFCI breaker for at least 5 minutes. Turn it back on and observe the startup sequence.
- Step 2 – Check supply voltage: Have a qualified electrician verify that the spa is receiving correct voltage (typically 240V for Catalina spas) and that the neutral and ground are correctly wired.
- Step 3 – Inspect for obvious damage: Open the equipment bay and look for burned components, melted wires, or water intrusion into the control pack.
- Step 4 – Note other codes: If Err alternates with another code (e.g., Sn1, FLO), address that specific fault first.
If Err persists with no visible damage and correct wiring, the control pack may need professional diagnosis or replacement.
