I'm a newbie and trying to diagnose problems with my AquaPure 1400/PureLink RS system. Upon seeing gen. fault warning, on my interior panel, I went to outside panel and found fault codes 170/187. The only lights on were power, cell reversing and service.
I then took readings on back board as follows: 1-8 = 80
2-7 = 69
3-6 = 21
4-5 = 0
Going further, I did the diagnostics on the front board: Salinity & R temp + Key C = 00
Salinity & R temp + Key D = 66
H temp + Key C & Key A = 66
From what I can gather, my front board is JUNK, but before I invest I thought I'd get some other opinions. I'm also questioning the wisdom of continuing with this system (it's about 6 years old) as I my also have cell and sensor problems. Any recommendations are greatly appreciated, as I read that this is not the most reliable system.
