Aquatrol Display 0

[grenona60]

Hi, since 2 days it't display 0 for the Salt, here is the detail of all setting on it.

Could it be more the cell T-5 or the Thermistor (current limitator) that causing this issue.

	Test 1	Test 2
Display show	0	0
Temp	72	72
Voltage	30.2	29.7
AMP	0,00	0,03
Output Salt	100P	100P
Salt Instant	-0	-0
Product Number	AL-7	AL-7
Firmware	1.11	1.11
return to beginning	0	22

thanks

Eitehr the thermistor or a burnt connection on the board.

Have you removed the board and examined the thermistor and the solder joints on the back of the baord?

Not yet, a reseller told me if I have no AMP readout on the display , it’s for sure the cell is dead

first I order thermistor to replace it, second I will clean the cell and see what going on

First you should examine the board and see what its status is.

You should only clean the cell with acid if it has visible scale on it that cannot be cleared with water spray and a Popsicle stick. Every acid cleaning will reduce the life of the cell.

Thanks I will let you know the result

For AquaRite, move the switch from auto to off and check all of the readings.

Move the switch back to auto and recheck the readings.

Move the switch to off for a minute and then back to auto and recheck the readings.

Switching the unit off and then back on makes the unit reverse polarity.

Report all readings.

What are the first seven characters of the cell and box serial numbers?

What is the actual salinity and how are you measuring it?

What is the T-cell size?

Is the T-cell size set correctly in settings?

To get the performance percentage of the cell in each polarity, divide the instant salinity reading in each polarity by the actual salinity reading.

For example, if the instant reading is 3,300 ppm and the actual salinity reading is 3,300 ppm, then the salt cell is working at 100%.

However, if the actual salinity was 3,800 ppm, then the performance percentage is 86.8%.

Anything over 75% is acceptable.

At75%, or lower, in either polarity, it's time to consider replacing the cell.

The instant salinity in both polarities should be about the same (+/- about 200 ppm).

You need to be really sure about the actual salinity reading.

You need to use a K-1766 salt test kit or a calibrated meter.

K-1766 Taylor Salt Test

Note that ProLogic, AquaLogic and AquaPlus use the Hayward T Cell.

However, the procedure to get the diagnostic readings is different.

Here is the procedure for ProLogic, AquaLogic and AquaPlus:

Go to the diagnostic screen, note the readings and then press the + button to reverse the polarity.

When the new numbers appear, see what they are.

Then, press + again and note the new readings.
