Interactive diagnostic wizard for Jandy TruClear salt chlorination system issues including low output, no flow, check cell alerts, and salt level problems.
Select the symptom your TruClear is displaying to get step-by-step troubleshooting guidance.

This interactive troubleshooting wizard is designed specifically for the Jandy TruClear salt chlorination system. Whether you are a pool homeowner troubleshooting a display message or a service technician running a structured diagnostic, the wizard adapts to your role and provides the appropriate level of guidance.
Select the "Homeowner" role for safe, practical checks you can perform yourself, or switch to "Technician" mode for detailed diagnostic procedures including cell current measurements, polarity reversal checks, and flow sensor testing. Each symptom card links to a comprehensive written guide when you need to go deeper.
The table below summarizes the most common Jandy TruClear issues and their meanings. Click the troubleshooter above for step-by-step diagnosis of each problem.
| Display / Symptom | Description |
|---|---|
| Low Output | Cell not generating adequate chlorine — check salt level, output percentage, and pump run time |
| No Flow | System not detecting water movement — verify pump is running, filter is clean, and minimum 20 GPM flow rate |
| Check Cell | Cell performance degraded — scale buildup on plates requires acid wash cleaning |
| Salt Level Error | Display reading does not match independent salt test — clean cell or verify water chemistry |

Turn off the pump, remove the cell from the housing, and visually inspect for white calcium scale on the plates. If scale is present, soak the cell in a 4:1 water-to-muriatic acid solution for 5 to 10 minutes. Rinse thoroughly before reinstalling. Check cell age before cleaning — if the cell is near end of life, cleaning may not restore performance. Measure cell output after cleaning to verify improvement.
The "No Flow" display means the TruClear is not detecting water movement through the cell. First, verify the pump is running, check for blockages in suction and return lines, and clean the filter if pressure is high. The system requires a minimum of 20 GPM flow rate through the cell. If flow is adequate but the error persists, a technician should check the flow sensor and its wiring.
Low chlorine output from a TruClear can be caused by several factors. Check the salt level with an independent test kit — low salt means less chlorine production. Increase the output percentage on the control panel if needed. Verify the pump is running long enough for your pool's chlorine demand. A technician can inspect the cell for scale or worn plates, check polarity reversal, and measure DC current during generation to determine if the cell needs replacement.
The Jandy TruClear and AquaPure are both salt chlorination systems made by Jandy (Fluidra). The TruClear is the newer model with a simplified interface and easier installation. The AquaPure is the legacy model with numbered error codes (120-145 series). Both work on the same principle of electrolytic chlorine generation from dissolved salt. Cell cleaning and maintenance procedures are similar for both models.
A Jandy TruClear salt cell typically lasts 3 to 5 years depending on usage, water chemistry, and maintenance. Regular cleaning and keeping your pH and calcium hardness in the recommended range will maximize cell life. When the cell is near end of life, you will notice declining chlorine output even after cleaning, and the system may display "Check Cell" persistently.
Yes. Select the "Homeowner" role and the wizard will show only the checks that are safe and practical for a non-professional to perform. Technician-level steps such as cell current measurements and flow sensor testing are hidden unless you switch to Technician mode. Always follow the safety warnings on screen, and consult a licensed pool service professional for any repair you are not comfortable performing.
