I know there's a high chance that the cell is dead but it is currently hard/very expensive to find a new one so I wanted to see if there are any troubleshooting options left. A couple of days ago, my saltwater pool became cloudy. The cell light flashes green (but salt and all other indicators are good on the IC40). Opened up the IC40 and it appears to be clean (no calcium buildup that I could see). Put it back together and started the pump. After about 5 minutes or so the cell light flashes green again. I did the diagnostic mode, and I should have 60% life left (the 40% was illuminated) even though the unit is 5 years old. I pressed mode again, and noticed the temp reading is roughly 10 degrees higher than the thermometer is reading from the pool (not sure if this means the thermistor is bad). Also, when in diagnostic mode, the LOW stayed red. When leaving the mode and back to normal, it cleared.
I ordered some test strips to check the phosphate levels (won't arrive till tomorrow). And I have a salt tester that reports almost 4000 PPM (which seems high) so the tester could be bad but the IC40 doesn't complain about low salt so I wasn't worried about it. When we opened the pool (a month ago), it was reading low salt which made me put too much salt in so I back washed the filter to remove some (adding in fresh water with a hose). I'm hoping that maybe the thermistor was going bad which is why we had the low salt issue at beginning of the season and potentially why the cell light is flashing. I'm not sure if 10 degrees off is a big deal or not though.
Any other ideas or things I can try? Thanks!
