‐ Troubleshooting Guide
1. No power to the Power Center, check breaker. If unit is wired to a time clock,
make sure it is turned on.
2. Transformer wiring is incorrect, check it is wired properly for incoming voltage.
3. Fuse (10A) may have failed, test and replace if necessary.
4. Transformer or Power Center circuit board has failed, replace the Power Center.
(p/n: PCR0002A or PCR0002J)
Check 4‐wire cable connecting the display to the power center.
Normal operation, unit is in BOOST mode. Press and hold both the Up Arrow and
Down Arrow simultaneously to activate/deactivate BOOST MODE.
Add Salt to achieve 4,000 ppm (mg/L).
Add Salt to achieve 4,000 ppm (mg/L).
Cell voltage is above 30. Check cell for scale, clean as necessary and balance water.
Chlorine is still being generated. The cell may be dirty or have calcium build up.
Inspect and clean the cell as needed.
Fresh salt may have not fully dissolved, or the salt level may be above 5000ppm.
The system will retest every hour. If the condition persists the system will lock out
and display a high current fault. A power reset will clear the fault.
1. Check / clean AutoPilot manifold union screen.
2. Increase variable pump speed if necessary.
3. Check pump for proper operation and service, as necessary.
4. Clean / service filter, as necessary.
5. Check system valve settings for proper flow to the unit.
6. Check for heavy scale accumulation on the cell.
7. Check for debris in manifold bypass check valve. Ensure valve is properly seated
when pump is off.
8. Check Tri‐sensor connection at power center.
9. Tri‐sensor may need to be serviced or replaced.
Confirm banana plugs are plugged in. Check for loose or damaged wiring inside
the power center. After correcting, power cycle the power center to clear error.
