Well, I've been pretty happy with my Pureline SWG until this week...it has just started shutting down on Low Salt (after running for a few minutes once switched on and presumably generating chlorine, based on the appearance of bubbles at the pool jets prior to shutdown).
I checked salt levels with the TFLPool Kits salt kit and with the AquaChek strips that came with the SWG - both were in agreement at ~2900-3000ppm.
I added 120 lbs of pool salt and ran the pump overnight, now I'm getting ~4000ppm with the AquaChek strips. But the SWG behavior is unchanged - still shuts down on Low Salt after a few minutes. Cycling through the menu, I see it's reading 2000ppm instantaneous salt and a very high water temperature of around 120 degrees (vs actual of 80 degrees per Aqualink). In the past, the cell temperature readings were in line with the Aqualink readings. Amps and volts are normal. I checked resistance across the temperature sensor pins and got 3750 ohms (in line with 120 degrees).
The cell only has 1000-1500 hours on it ("check cell" light flashes every 500 hours and has only flashed twice). I've never observed any scale or build-up on the plates, and have never cleaned them with muriatic acid or vinegar. I tried scraping them off with zip ties this morning but nothing came off. My calcium hardness has always tested in the 250-300ppm range.
I'll be calling InyoPools today to see what they suggest, but thought I'd check with the TFP community as well. Unfortunately the system is about 1 month out of warranty, but if my cell has failed prematurely I hope they'd at least offer a discount on a replacement.
