Jandy Aquapure Issue. Front Board Or Sensor?

[ryanbt]

I have a 6 year old 20,000 gallon pool with the Jandy AquaPure 1400 system.

Last year the salt cell failed and I had the 2 port one replaced with a 3 port cell. In August of last year the sensor failed and I replaced that as well.

About two weeks ago, the system was throwing codes 172, 180 and 181 and also displaying 25500PPM on the main display.

This past weekend I did my big spring pool pump cleaning and also cleaned the cell and the sensor. After I put it all back together it is only throwing one code, 144 for low salinty. I checked the salinty manually and it is fine. I did some online research and also tested the front board of the AquaPure wall unit. All tests of the front board were off by one number (which I read somewhere was OK).

Does anyone know if the problem is my sensor, or is the front board the problem?

Thanks in advance for your help!

My tester has never given me a salinity reading of "fine". What is the number? Also, what is the color of the epoxy on the sensor? it will be either white, or black.

Hi Pool Clown,

I have the same problem and my redings of the test

Disconnect the flow salinitytemp sensor

from the front board. Press and hold the test buttons marked salinity and R-temp. While still pressing the test buttons press the ‘Salinity’key (‘C’) on the front cover of the unit. The LCD should read 2.8 gpl*. While still holding the two front board test buttons press the ‘Pool Temperature’key (‘D’). It should read 75°F or 24°C. Next, press and hold the board ‘H-Temp’test button, and at the same time press the ‘Salinity’key (‘C’) together with the ‘Chlorine Production Rate’arrow down key (‘A’) on the front cover of the unit. The LCD should read 91°F or 33°C. If the readings are correct then the front board is O.K. and the problem is with the flow sensor.On the other hand if the readings are different then it indicates that there is a problem with the front board.

1. 2.8 gpl
   
2. 74 F in stead of 75
   
3. 90 F in stead of 91
   

Can you let me know if it is the front board, Sensor or both hope not!!

Thanks in advance.

Saludos

I have changed maybe 3 front boards on these units since they went on the market.

I cant count the amount of sensors i have changed.

Try this.

My Jandy 1400 system is producing chlorine. The flow light is not on and the salinity reading is --. The service light is on and codes 172 and 185 are displayed. The cell is clean and I have cleaned the sensor per Jandy instructions. How do I know if it is the sensor or the board?
