How to Fix / Troubleshooting
Safety: Turn off power at the GFCI breaker before inspecting electronics.
- Hard reset: Turn off power for at least 5 minutes, then restore. Observe if the error returns immediately.
- Disconnect peripherals: With power OFF, unplug non-essential components from the control board (ozone, auxiliary panels, stereo interface) and restore power to see if the error clears.
- Inspect for damage: Look for burn marks, swollen components, or water intrusion inside the control pack.
General error codes often indicate a failed control board; replacement of the Artesian control pack is usually required.
