Jandy aquapure SWG no flow

[biscuit4321]

Hi,
When my pool filter pump starts up the panel lights green saying there is flow through the salt cell. Then it turns off after less than a minute and the screen reads no flow. I have recently cleaned the salt cell with Muriatic acid and cleaned the 4 filters. Salinity is at 3.3 and current temperature should be sufficient. I have also tried to hit the reset button on the Jandy Aqualink panel above the Auto/Service/Timeout lights but the issue doesn’t resolve. Does the Jandy aquapure sensor need replacing? Any advice on troubleshooting?
Thanks for any help!

Welcome to TFP.

Read Jandy AquaPure SWG - Further Reading

Causes of NO FLOW can be:

• Actual low flow. VSP set too low? Make sure skimmers, pump basket, are filter is clean and nothing else clogged.
• Crust (like calcium) over the button. Water can't carry the heat away. Check by removing the sensor and looking for it. Clean gently as needed.
• Failing heater element. Can't draw expected current. Replace sensor.
• Sensor wiring problem. Check connections inside the box.
• Bad electronics in the box. Least likely, but if the flow and sensor are good, this is all that's left.

If you have a No-Flow error try resetting the circuit breaker and re-calibrating the tri-sensor before you consider replacing it.

You can find instructions for replacing and calibrating the tri-sensor in the AquaPure and PureLink Tri-Sensor Adapter Installation Kit Manual.

Disconnect the flow salinity temp 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.

When the testing and repair is complete reconnect the flow sensor and reset the internal computer (do this by restarting the unit).

*Note: If the the salinity reading has been recalibrated this reading maybe different.

Before condemning the board check salinity setting.
