ic40, Flashing lights and No flow Light

[LFC97pool]

I have a Pentair IC40 Salt Cell and went to check things out this morning as the pool looked a little cloudy and the flow was a bit bubbly. The pool is an inground, Vinyl, about 32,000 Gallons, located in Eastern VA. I saw that the IC40 had the RED No Flow indicator on and the salt level indicators were flashing (red & green). I took this as a chance to clean it and see what that might do. IT WAS FILTHY.

I did the diagnostic check and it showed the cell to be at about 60% life but all other items cleared (besides the known current issue)

However, when I put it back in the system, plugged everything in, and turned it on the flow light almost immediately went to green and then back to red. And the Salt level indicators never stopped flashing. For now I am putting the winterizing pipe back in and taking the Salt cell out of line so I can maintain flow and keep cleaning the pool through the skimmers and filter.

But does this sound like a Flow Switch replacement should work? or should I put in a call to my Home warranty so they can send out a pool repairman to do the deep dive into the repairs?

LF,

1. Nothing works if the flow light is not green.

2. When the cell initially starts up it does a salt test. During this test, the red and green salt lights will flash like a railroad crossing, until the test is done. This test will never work if there is no flow.

3. When you have a low flow light, the first thing to test is the actual flow. Does the water coming back to the pool seem to be strong or weak. If you have a strong flow, then the flow switch may be bad. If you have weak flow, then most likely your filter is dirty.

Thanks,

Jim R.

I definitely have good flow. I initially performed a Backwash & rinse to ensure that nothing was blocking the lines. Then I pulled the Salt Cell from the whole equations and there is still plenty of flow.

Is there a way to test the flow switch other than simply replacing it?
