Jandy Aquapure problems

I replaced my flow sensor recently and cleaned the cell grids. I replaced the sensor because after a few minutes of running, i would get no flow. The board tested fine per the test instructions from jandy. Even after replacing the sensor, I still get no flow after a few minutes of running. This is with a clean DE filter and adequate flow to run suction side vacuum and spa spillover.

The pool is about 3 years old. I live in the CA high desert and have high calcium levels. Right now, 650ppm. I don't want to drain the pool every year and have read that higher calcium levels are OK so long as ph and alkalinity are well managed, and negative csi is sustained. I monitor water chemistry religiously and pool is always balanced.

The grids show some corrosion, but it doesn't seem excessive to me. The few minutes when the cell is running, i see bubbles from the returns as i normally would, so I believe it is working.

My questions:
1. Is it possible that the cell has failed and needs to be replaced? I don't imagine that a failing cell would cause no flow, and I assume it would throw error codes of some sort?
2. It also seems as if the pool builder wired the aquapure system to be always on. I have a current generation jandy VS pump with the PUMPIQ01 controller. I assume that the aquapure system should be wired to the pumps auxiliary. There are no relays in the aquapure electrical box.
3. The pool was built just three years ago. If it's supposed to be wired so that the aquapure system is completely off when the pump isn't running, I intend to reach out to the builder and ask that the problem be corrected.

Oddly, I'm able to sustain adequate chlorine levels with pump running 8 hours per day on high and the cell set to 50%, which makes me believe it is cycling between flow and no flow throughout the day. I haven't had hours to sit and watch the system as it runs as i work full time, have young kids, and am trying to wrap up a masters degree at the moment.

I appreciate any help that can be provided. I love this site and the TFP method has helped me have an algae free crystal clear pool since the day we first filled it. I'm just at my wits end with the generator. I'm tempted to throw in the towel and just use liquid chlorine at this point as it would be easier than spending hours fooling around with the generator that doesn't work dependably.

Help me TFP, you're my only hope... Other than paying a pool company way too much money to come figure this out for me! LOL
 
Flow reading okay for a while then going to zero makes me suspect an air bubble accumulating over the sensor. Is your installation cell position one of those shown in the manual? If horizontal, the sensor plug must be down. nb: I'm just a fellow Aquapure owner. If one of the experts chimes in, please trust them over me.

I appreciate the reply. It is in horizontal configuration with the sensor on the bottom side, so it shouldn't have any air bubbles.

Running your Aquapure at 50% for 8 hours will generate 1.1 ppm of chlorine a day.

It sounds to me like your cell is working fine.

If you need more chlorine, you need to run the pump longer or the cell at a higher %.

What is your CYA?

I would think you need more than 1.1 ppm of chlorine per day in the high desert of California.

Levels attached.

I keep the solar cover on when not in use. I think that minimizes chlorine loss.

My concern is that the SWG controller keeps randomly showing no flow when there is flow present and I have no idea why!

If you run the pump and SWG for 8 hours and get sufficient chlorine, I would not worry about it.
