So, I get home from work one day a week or so ago to find our brand-new 3 week old pool with the pump/chlorinator and the deep end LED not working, along with some other non-pool related stuff hosed up as well. Now I know what the likely cause is....but seeing as I wasn't there to witness it, I'm going with "who knows" as the official diagnosis. I called the PB and after a board swap in the ET4, we appear to be running aside from the light which is on order. My main concern is confirming that my chlorinator is still outputting correctly. Salt and all my other chems (salt, FC, and CC) are still within a pretty good range, but i'm having to run my IC40 at 90% to keep within the 4ish range. I haven't toyed with dialing it down and seeing how far it drops, seeing as I really don't have the time to get into a SLAM type situation at the moment. I mentioned it to the guy that came out, and he seemed tho think this is normal. He stated that with the ic40 producing 1.3 pounds at boost over 24 hours, that 1 lb should raise it by +1 on a pool roughly my size. That itself makes sense to me, but I'm still thinking that having to run a 40,000 gallon chlorinator at 90% just to keep up on a 23-24k pool with that seems out of line. Nothing is showing any errors that I can use as a negotiating point.....so am I crazy to be concerned?
