Why is my AIS Water Filtration System chlorine generator not producing enough chlorine?
- B
  Brandi ThomasAug 12, 2025
  If your AIS Water Filtration System's chlorine generator isn't producing enough chlorine, there are several potential causes. First, the chlorine production level might be set too low; try adjusting the control knob clockwise to increase production. Second, the generator may not be running for a sufficient amount of time; increase the operation running time. A calcified electrode can also reduce chlorine output, so you should clean the electrode. Finally, incorrect water chemistry can impact chlorine generation, so ensure your water chemistry is properly balanced.

What to do if the low salinity light is on or flashing on my AIS Water Filtration System?
- R
  Rachel BoydAug 15, 2025
  If the low salinity light is flashing on your AIS Water Filtration System, it typically indicates that the water salinity is too low. Have the salinity level tested by a pool professional and increase it if necessary. Another possible cause is a calcified electrode, which requires cleaning. A faulty electrode may also be the reason, so have it tested and replaced if necessary.

Why are there no lights on my AIS Water Filtration System chlorine generator and the pump is not running?
- B
  billyfordAug 20, 2025
  If there are no lights on your AIS Water Filtration System's chlorine generator and the pump isn't running, the first thing to check is the power supply. Unplug the chlorine generator from the power and test the outlet with another working appliance to ensure there is power. Another possibility is that the time clock is in a designated off period, or the switch is in the OFF position; switch to BYPASS to circumvent TIMER or OFF functions.

What to do if Status Light (3) is flashing and the generator is beeping on my AIS Water Filtration System?
- D
  Dylan JacobsAug 23, 2025
  If Status Light (3) is flashing and the generator is beeping on your AIS Water Filtration System, it could be due to a few reasons. One possibility is that the pump isn't running, the filtration is blocked, or there's an air lock. A large air bubble in the electrode housing can trigger this alarm, so clean out the skimmer box, check and clear any blockages, and re-prime the pump. Another potential cause is that the electrode lead isn't properly plugged in; double-check that the electrode lead plug is securely connected to the electrode.

Why is the high salinity light on or flashing on my AIS Water Filtration System?
- S
  samantha63Aug 27, 2025
  If the high salinity light is on or flashing on your AIS Water Filtration System, it typically means the pool salinity is too high. Have the salinity level tested by a pool professional and decrease it if necessary. If the salinity level is within the correct range, the chlorine generator may be faulty. In this case, contact your dealer or AIS Water for assistance.

Why is the circuit breaker tripping on my AIS Water Filtration System?
- H
  hleAug 30, 2025
  If the circuit breaker is tripping for your AIS Water Filtration System, it could be due to several reasons. A mains power surge may be the cause; set the machine to off and push the circuit breaker. A fault with shorted electrodes could also be the problem; visually inspect the electrode and check for foreign or conductive surfaces. If found, remove and clean the cell. If neither of these resolves the issue, there may be a fault with the power supply, in which case you should contact your dealer or AIS Water.

Why is Status Light (3) on and the pump is running, but no other lights are on, on my AIS Water Filtration System?
- M
  Michael DukeSep 3, 2025
  If Status Light (3) is on and the pump is running, but no other lights are on, on your AIS Water Filtration System, it could mean that the chlorine generator production is turned off. To resolve this, adjust the control knob clockwise to increase production.

What causes white powdery material on the pool bottom with my AIS Water Filtration Systems?
- J
  Jonathan JonesSep 7, 2025
  If you notice a white powdery material on the bottom of your pool when using the AIS Water Filtration System, it's likely due to excessive water hardness. Test the water chemistry and adjust accordingly to resolve this issue.
