Possible Causes
Out-of-range sensor reading, Sensor not fully immersed, Control pack firmware issue, Loose sensor connector
How to Fix / Troubleshooting
Safety first: Turn off power at the GFCI breaker before handling sensors or the control pack.
- Check sensor seating: Ensure both temperature and high-limit sensors are fully inserted into their wells or clamped securely to the heater tube.
- Inspect connectors: Unplug and replug sensor connectors at the control pack, checking for corrosion or moisture.
- Compare with external thermometer: Measure water temperature with a separate thermometer. If the displayed temperature is significantly off, replace the water temperature sensor.
- Firmware reset: Power cycle the spa. If SE persists, consult Passion Spas documentation for any specific reset procedures for your control pack.
Ongoing SE errors after sensor replacement suggest a control pack issue that requires professional service.
