Why is the water flow LED blinking red on my CAS Water Filtration System?

  The water flow LED might blink red on your CAS Water Filtration System due to low or no water flow. Ensure sufficient water flows through the chlorinator cell, verify that the pump is running, check for air pockets (perform backwash if needed), and inspect the skimmer and pump baskets to confirm they are clean and securely tightened. Also, check the cell and brass pins, and tighten the cell connections if necessary. Suction leaks could also be the cause.

What to do if my CAS Water Filtration System has power and direction lights on but no output lights?
- A
  Andrew MartinezAug 19, 2025
  If your CAS Water Filtration System shows power and direction lights but no output lights, there are several things to check: * Make sure the cell is connected properly by checking the brass pins and cell connections, tightening if needed. * Adjust the output using the Output (+) button to increase the lights. * If there's excessive buildup in the cell, cleaning it may resolve the issue. * Low salt levels can also cause this, so verify and adjust as needed. * The cell could be damaged or at the end of its life; damaged coating reduces cell life and output. If all else fails, the cell might need replacing.

Why is the chlorine output low or non-existent in my CAS Water Filtration System?

  Low or no chlorine output in your CAS Water Filtration System can stem from several causes. Start by checking the output settings to ensure they are correctly configured. Excessive calcium buildup on the cell plates can act as an insulator, so cleaning the cell electrode is important. Also, verify the salt level, pH, and stabilizer levels, adjusting them as needed. If the cell is old, it may be nearing the end of its life. If none of these steps resolve the issue, further troubleshooting may be needed.

Why is the output reading low on my CAS Water Filtration System?

  James GeorgeAug 28, 2025
  A low output reading on your CAS Water Filtration System can be due to several factors. First, ensure the output is not set too low by adjusting it with the (+) button. Low salt levels can also cause this, so check and adjust the salt level accordingly. Calcium buildup on the cell plates can act as an insulator, requiring you to clean the cell electrodes. Low water temperature and insufficient water flow through the cell can also reduce output; backwashing the filter may help.

How to fix a CAS Water Filtration System pool pump outlet if it's not working properly or the pump is always on?
- E
  Erin CarterSep 3, 2025
  If the pool pump outlet on your CAS Water Filtration System isn't functioning correctly or the pump is always on, ensure the pump is plugged into the bottom of the power pack and not directly into the wall outlet.

  If the warning LED is solid red on your CAS Water Filtration System, it indicates an internal temperature trip. This may be due to a salt level that is too high. Check the salt guide. The fault will reset once the transformer cools down.

What to do if my CAS Water Filtration System has no operation at all, and no lights are on?
- X
  xcombsSep 9, 2025
  If your CAS Water Filtration System shows no operation and no lights are on, first ensure that the unit's power cord is properly plugged into the wall outlet and that the outlet is turned on. If it's plugged in but still not working, test the wall outlet with another working appliance to rule out an issue with the power source.

Why is the cell not cleaning and there's excessive calcium buildup on the cell, or the power pack isn't changing direction in my CAS Water Filtration System?
- S
  Sheri RobinsonSep 12, 2025
  If the cell isn't cleaning, and there's excessive calcium buildup, or the power pack isn't changing direction on your CAS Water Filtration System, this could be due to excessively high calcium levels, a change of direction time set too high, or a faulty Main Power Supply PCB. Check the calcium hardness and adjust the water accordingly. Manually try to reverse direction. Decrease the cell cleaning time.
