What to do if Zodiac Lighting Equipment displays 'pH REGUL. STOP'?
- D
  debraturnerSep 2, 2025
  If the Zodiac Lighting Equipment shows 'pH REGUL. STOP', the pH setpoint hasn't been reached after 5 hours of injection. This could be due to a faulty connection, calibration error, a failure or dirty pH sensor, an empty pH minus container, a pump that isn't primed, or high alkalinity. Check the pool's pH using a photometer or test strip. Inspect the pH sensor wiring, clean and calibrate the sensor, and replace the pH container if empty. Test the peristaltic pump, reduce the alkalinity level, and consider replacing the pH sensor.

What to do if Zodiac Dual Link is 'OVERHEATING'?
- M
  Mr. Arthur Park PhDAug 31, 2025
  If your Zodiac Lighting Equipment is overheating, it means the temperature inside the control box is too high. Chlorination will slow down above 85°C and stop above 90°C. If the box is installed outdoors, protect it from direct sunlight. Chlorination will resume automatically once the temperature falls. If the problem persists, there may be an issue with the appliance.

What should I do if my Zodiac Lighting Equipment displays 'CONDUCTIVITY' error?
- C
  chenryAug 30, 2025
  If your Zodiac Lighting Equipment displays a 'CONDUCTIVITY' error, it may be due to low water conductivity (low minerals), especially in models with a temperature sensor. This can also be caused by low water temperature or low mineral levels due to water loss or dilution. The cell could also be worn, scaled up, or broken. Check the water temperature and the condition of the cell plates. Measure the mineral concentration in the pool water using a salinity tester or test strip, and add minerals to maintain a level of 4 g/L. If unsure, contact your retailer.

What to do if Zodiac Lighting Equipment displays 'PROD. ERROR'?

  Julie HarrisonAug 29, 2025
  If your Zodiac Lighting Equipment shows a 'PROD. ERROR', it could be due to a poor connection of the power supply cord from the cell or inside the appliance, worn, scaled up, or broken cell plates, or an internal electronic problem in the control box. First, switch off the appliance and the power supply, then check all cable connections (mains power supply, cell, etc.). Second, consider replacing the cell. Third, check the power supply board by contacting your retailer.

What to do if Zodiac Lighting Equipment shows 'NO FLOW CHECK PUMP'?
- M
  Megan MurrayAug 28, 2025
  If your Zodiac Lighting Equipment displays a 'NO FLOW CHECK PUMP' error, it could be due to several reasons. First, the filter pump might have failed. Second, the filter or skimmer(s) may be dirty. Third, the by-pass valve(s) might be closed. Fourth, there could be a disconnection or failure of the flow switch. To resolve this, check the pump, filter, skimmer(s), and by-pass valve(s), cleaning them if necessary. Also, inspect the wire connections of the flow switch and ensure the flow switch is working correctly; replace it if needed.

What to do if Zodiac Dual Link Lighting Equipment displays 'ACL ERROR'?
- J
  jonesjasonAug 27, 2025
  If your Zodiac Lighting Equipment displays an 'ACL ERROR', it means the ACL regulation authorized chlorine production for over 30 hours without reaching the ACL set point. Check the pH in the pool. Clean and calibrate the sensors. Replace the buffer solutions if necessary and replace the sensors.

What to do if my Zodiac Dual Link Lighting Equipment shows 'ACL HIGH'?
- T
  Tyler SmithAug 27, 2025
  If your Zodiac Lighting Equipment displays 'ACL HIGH', it indicates that the measured Redox potential is more than 150 mV above the set point, suggesting excessive chlorine levels. Clean and calibrate the sensors. Wait until the error message disappears, which indicates no chlorine production. Ensure the stabilizer level is below 30 ppm, the water's alkalinity is OK (avoiding well and rain water), and reduce the ACL set point.

What to do if Zodiac Dual Link Lighting Equipment displays 'PH ERROR'?
- B
  Bobby SchneiderAug 26, 2025
  If your Zodiac Lighting Equipment shows a 'PH ERROR', it means the pH adjustment has performed 5 cycles without reaching its set point (more than 10 hours). Check the pH in the pool. Also, verify that the pH minus container is not empty and replace it if it is. Test the peristaltic pump to ensure it is primed. Clean and calibrate the pH sensor, or replace it if necessary. Replace the pH7.5 buffer solution if necessary. Check the selected pool size. If the peristaltic pump has not been operated for a total of more than 72 hours, it may mean that the pH in the pool does not need to be corrected.

What to do if my Zodiac Water Filtration Systems shows 'NO FLOW CHECK PUMP'?
- M
  mccalladrianAug 23, 2025
  If your Zodiac Water Filtration System displays 'NO FLOW CHECK PUMP', it indicates a problem with water circulation. This can be due to a filter pump failure, dirty filter or skimmer(s), or closed by-pass valve(s). Inspect the pump, filter, skimmer(s), and by-pass valve(s), cleaning them as needed. Also, check the flow switch wire connections and ensure the flow switch is working correctly; replace it if necessary.
