The Pentair IC40 (Intellichlor 40) is a chlorine generator that was designed to maintain optimal levels of chlorine in your swimming pool around-the-clock. It uses electricity to achieve this task but can occasionally run into different types of problems. Therefore, we want to look at the common Pentair IC40 problems and how you can resolve them.
Remember: You should note that you can troubleshoot most of the smaller issues that may come up with your Pentair IC40 but some might require the help of a professional, especially the complex ones.
Pentair IC40 Problems and Solutions
Some of the most experienced problems with Pentair IC40 include:
1. Life Light Flashing
That means that the Pentair IC40 life is running out – limited life remaining. Under proper operation, the intellichlor should provide at least 10,000 hrs. of operation, which is 3-5 years of service. In many instances, you can extend the life if you monitor the level of chlorine properly and the salt and chemical balance level.
You can manually check life and cell usage at any moment. Just press and grip the “More Button” for 3 seconds and the device will go into “Status Check Mode” and show on the bottom 5 output percentage LEDs in 2000-hr multiple, the amount of time your gadget has operated (20 percent represents 2000 hrs. of use, 60 percent represents 6000 hrs. of use, and so on.
2. Flow Light is Red
The light should be green under normal operations. That means that proper flow is passing via the cell. If the light is red, that means that there is insufficient flow via the cell for the right operation.
Check to ensure that the pool pump is switched on and the water is flowing freely. If you detect insufficient flow, then uninstall the cell and inspect the flow switch situated in the front part of the cell to guarantee proper operation. In case the switch can no longer work, it’s time to replace it.
3. Salt Levels are Repeatedly Flashing
The 3 salt levels LED’s Red, Yellow, and Green are designed to repeatedly flash for the about 2 minutes after every startup. Hence, wait for about 2½ minutes to allow the Pentair IC40 to properly sense the level of salt.
After that, 1 of the 3 LED’s will be illuminated displaying salt level.
a. “Good” Salt Light (Green)
This doesn’t mean that your pool has the proper level of salt. In fact, the salt level might be excessively high. Inspect the level of salt in your spa or pool. If the level is pretty high, reduce it by draining some of the water out of your pool and add fresh water.
Repeat the process until you get the desired concentration. Leave your pool for one day to allow the pump to circulate and mix the water and then allow your IC40 to check the level of salt again.
b. “Add” Salt Light (Yellow)
Yellow means that the level of salt is slightly low. Check the level of salt in your facility and add the right amount salt according to the size of your pool or spa.
Wait for at least one day and then recheck the system to ensure that the IC40 is reading good salt or green.
c. “Low” Salt Light (Red)
The salt level is extremely low and your device is no longer releasing chlorine. Check the level of salt in your Spa or pool. Add the right amount of salt according to the chart in your manual.
Note: Before you add a huge amount of salt, have a professional inspect your facility.
Wait for about one day to recheck the IC40 to ensure that it is reading good or green salt.
4. Possible Cause of No or Little Chlorine Residual
- The pump is off or power is off.
- Output set 0%.
- Filter pump time is short.
- High level of nitrogen.
- Lower stabilizer level.
- Excessive scaling on the cell.
5. Other Issues
Cold Water Light (Red) – Water is below 52 degrees F. Adjust the temperature accordingly.
No Power – Fuse is open, no AC power, or issues with wiring. Diagnose the problem and rectify accordingly.
Pentair IC40 problems come in the above nature and can be solved through the solution provided.
