To address your initial question, if it's installed correctly, the panel will power off anytime the pump isn't running. This is a critical safety function; if the cell operates without proper water flow, it can explode. When you notice the lights off, is the pump also off? Honestly though, it really doesn't matter whether the lights stay on at the panel of your salt cell. The only thing that matters is whether it's putting the correct amount of chlorine into your water. You probably don't need to buy another one, and even if it was under warranty, the people at Pentair are going to ask you exactly the same questions that have already been asked in this thread. We recommend getting a reliable test kit and using the app to track progress and calculate chemicals. There's dozens of threads about panel glitches and how to program the system. We can try to explain it to you, but we can't understand it for you. And we DEFINITELY can't push buttons and set up the system. That's got to happen where you are.
To address your second issue with the fellow members of the website, well that might be a little different process. I've been here about a year now and definitely had some issues getting into the flow of how things work here. I've personally had strong words and disagreements with both Jim and Marty on occasion, and it was almost entirely due to my own ego and ignorance. That being said, I'd put just the two of their collective knowledge and willingness to teach above all the other DIY internet pool forums combined. If Reddit gives you more responses and that's what you need, you're welcome to try that website, and we'll happily welcome you back if they don't help you keep your pool water clear. Consider two users in this thread have over 70,000 posts among them, and it's just amazing watching them and the rest of the dedicated members of this site help time and time again. It'd make sense that with all the work they do here and on their own pools that they'd be asleep after midnight. We don't do conflict here, we don't do drama. We do easy, clean pool water. Join us when you're ready. Seriously, the only thing anybody here gives a darn about is helping folks keep their pool water clear. It's a little bit spooky.
