Possible Causes
One or more temperature sensors out of range, Mixed sensor types installed, Loose sensor connectors on control board
How to Fix / Troubleshooting
Safety: Turn off power before accessing the control pack.
- Identify sensors: RivieraPool spas typically use a pair of matched sensors (water temp and high-limit). Verify both are the correct type for your control pack.
- Check connections: Unplug and replug each sensor at the control board, ensuring a snug fit. Inspect for corrosion or bent pins.
- Replace as a pair: If one sensor has been replaced recently with a non-matching part, replace both with a matched RivieraPool sensor kit.
- Power-cycle: Restore power and see if SE clears. If not, the control board's sensor circuit may be damaged and require replacement.
