Possible Causes
Mismatched sensor pair, Incorrect sensor type installed, Control board firmware expecting different sensor, Sensor out of calibration
How to Fix / Troubleshooting
Safety first: Disconnect power before changing sensors.
- Verify sensor type: Ensure that replacement sensors are genuine or Aquavia-approved NTC sensors with the correct resistance curve.
- Replace both sensors as a pair: On systems using dual sensors, replace both the temperature and high-limit sensors together to maintain calibration.
- Check firmware compatibility: If the control pack was replaced, confirm that the firmware version matches the sensor set installed (consult Aquavia documentation or support).
- Power cycle: Restore power and reset the spa. Confirm that the SE error is cleared and that temperature control is stable.
