i have a three year old Aquapure 1400, cell reversing light steady - non operational with a 170 service code. 170 comes up as either a incoming voltage issue or a front board issue. I rewired the system completely recently adding in a heavy duty Intermatic pool timer, and it worked for two weeks fine, but after adding in a GFI outlet, it kicked in the error code after 24 hours. Nothing new has been introduced on the line in terms of load devices - operated for two years but rewired and all other devices are fine (heater, solar valve, pump, outlet).
normal operation has been 10-20% on 24/7 - cell was acid cleaned a month ago before season start, which barely needed cleaning. I've taken out the flow sensor and used a kitchen sponge to scrub - two of the sensors are bright and shiny, the third is a bit dull metal.
troubleshooting diagnostics:
Transformer Voltage
Backboard A to B: 77.4V (should be approx 75V)
Backboard
1-8 77.2V (should be 75V); 2-7 68.8V (should be 65V); 3-6 20.6V (should be 21V)
Front Board AC Voltage
A to C: 20.7V (should be around 21VAC)
Troubleshooting Front Board
Salinity 2.9gpl (vs 2.8gpl)
Pool Temperature: 74F (vs 75F)
H Temp: 90F (vs 91F)
I spoke to Jandy tech support and they said the board voltage all looked fine as did the three board diagnostics readings.
All indicators points to either replacing the front board or the flow sensor - the question is which. The reco was to get a tech and just start replacing boards - which of course is the expensive option at least in Canada, since parts from a pool store here are about double the U.S. online price ) - although you only pay for what you need, plus the $100 service call.
Does anyone in Canada know where to get Aquapure parts online from a Canadian source?
Any other recommended ways to clean the flow sensor other than the green kitchen sponge?
any other suggestions are appreciated.
