What should I do if my Zodiac pH Link displays 'CONDUCTIVITY' error?
- R
  Rachel YoungAug 31, 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 pH Link Lighting Equipment displays 'PROD. ERROR'?
- M
  Margaret GillespieAug 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 pH Link shows 'NO FLOW CHECK PUMP'?
- A
  Amanda WilkinsAug 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 Lighting Equipment displays 'ACL ERROR'?
- N
  Nathan AndersonAug 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 Lighting Equipment shows 'ACL HIGH'?
- A
  Alejandro CruzAug 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 Lighting Equipment displays 'PH ERROR'?
- T
  Terri ClayAug 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 pH Link Lighting Equipment shows 'PH LOW'?
- D
  Douglas ReedAug 25, 2025
  If your Zodiac Lighting Equipment displays a 'PH LOW' error, it indicates the measured pH is 0.8 units or more below the set point. First, check the pH in the pool. You should also check the set point and the selected pool size. Clean and calibrate the pH sensor, or replace it if necessary. Finally, replace the pH7.5 buffer solution if needed.
