Jandy Aquapure 1400 - salt cell not getting any power

[scottdhead]

I have a Jandy Aquapure 1400 system and the cell is not getting any power. The Sensor Indicator Module shows no lights on. I am also getting error codes 172, 183, and 184. I replaced the Power Interface Board and I still have the same issue. What I think it could be...

• Bad DC cord - What voltage should I be reading off the Power Interface Board?
• Maybe it's an issue with the power getting to the Power Interface Board - How would I test that?
• Maybe something just needs to be reset after the board replacement

If it's relevant, the tri-sensor was replaced about 3 months ago. About a month later, the cell lost power. Any ideas on what to try next? Thanks in advance.

Hi there, Like many of the similar threads I am a new owner to this pool. I assume this equipment is several years old and the previous owner claims to have had no issues ;). When I fired up the SWG I was getting several error codes (FWIW they were 172, 173, 186, 187, 188). I followed the...

Thanks for the help. I have a different board though.

I think the proper name for my SWG is Jandy AquaPure PLC1400 (R0452400). Sorry for the confusion.

AFAIK there has been only one model Aquapure system.

I think I recall reading that there was a newer Power Interface Board (R0467600) made at some point. I have the R0467600 board

I found the Jandy Workbook and the specific board I have: Troubleshooting - Transformer Voltage - Jandy AquaPure Workbook [Page 17] | ManualsLib
I'll check voltages and report back.

OK I tested all test points called out in the workbook...

75 VAC Test Points: 85 (Range is 67-87) - OK
65 VAC Test Points: 73 (Range is 60-75) - OK
VAC1 / VAC 2 Test Points: 21 (Range is 17-24) - OK
+12 VDC Test Points: 11.7 (Range is 11.8 to 12.2) - Slightly out of range but probably OK?
+5 VDC Test Points: 5.0 (Range is 7.8-5.2) - OK

The +12 VDC test was technically out of range but only by .1 V. Since I already replaced the board and still have the same issue I'm thinking the board is OK. But please verify that for me. Here are the problems:

Cell connection test points: 0 V (Range is 22-28)
120mVDC test points: 0 mV (Range is 100-145)

So it would seem that there is no power being sent to the cell at all. Could be a bad DC cable? Or is the tri-sensor the problem? That was replaced 3 months ago but I guess it could have gone bad. To me, it seems that the board is not sending power because it's getting bad readings from the sensor. I should also mention that the salinity reading from the sensor is way out of wack. It's currently reading 12750 PPM. I have tested the water myself and it's at 3900 ppm. Try a new sensor?

Power is not going to be sent to the cell if the TriSensor does not have water flow.

If you don't have good water flow through the sensor then it will not get a good salinity reading.

183 & 184 codes point to Tri-Sensor problems.

Looks to me like there is a problem with the Tri-sensor.

Did you try to calibrate the salinity? Maybe because it is reading so high, it will not switch on. I have had the Aquapure for only one season, and had to calibrate the salinity to be in line with my TF-100.

 

[scottdhead]

It was calibrated after the tri-sensor was first replaced 3 months ago. I have not calibrated it recently. Seems odd that it would just all of a sudden, one month after replacement start getting such wacky salinity readings if it was reading it properly before that. I can try that though before replacing it.
