Water temp is 88. I have had a rag over the clear plastic of the cell.I doubt you are running the heater but what's the actual water temperature?
Using a multimeter, open the T-Cell and test the resistance of the T-Cell thermistor. Or cut either the Red or Blue wire and test to see if the Temperature display is 77.
Reference the T-Cell pinout here > Hayward T-Cell Pinout
I'm sure other experts will not hesitate to point you in the right direction on how you can jury rig a thermistor replacement.
Is this what you have?I just installed a new T9 Calimar cell.
Is this what you have?
Does the cover plate pop off?
If yes, can you pop it off and show the wires?
The 3 year warranty should cover the defect.

Holding the plug vertically with the cord going down and looking at the connection points. 1 is top left, 2 is top right, 3 is second down left and so on with 9 being lower left and 10 being lower right.
To test the thermistor test between points 6 and 10 using a multimeter, the resistance should follow a 10k thermistor chart.
- 1) Black - Power to cell
- 2) White - Power to cell
- 3) Black - Power to cell
- 4) White - Power to cell
- 5) Brown - Not used
- 6) Red - Goes to thermistor
- 7) Orange - Not used on older models, used for cell ID chip on new models.
- 8) Yellow - Not used on older models, used for cell ID chip on new models.
- 9) Green - Not used
- 10) Blue - Goes to thermistor.
LCD display will read “HOT” when the water temperature is above 140 F.
140 degrees is 2,489 ohms and the ohms go down as the temp goes up, so the resistance (Ohms) must be below 2,489 ohms.

If you can access the thermistor wires, you can wire in a new thermistor with an external thermistor installed near the cell.
Red and Blue are the thermistor wires for Hayward.
Hayward added the orange and yellow wires for an ID chip that identifies authentic Hayward cell for the newer systems.
The Calimar might use different color wires, but they will be the ones that go to the thermistor and to points 6 and 10 on the plug.
Don't start a new thread.I will post a thread on here to see if this is a know problem with a specific component, like a resistor or something, that I can swap out with a soldering iron, instead of a whole new board. thx !
How will anyone see it ? lolDon't start a new thread.
Keep everything here.
I did not know that, so nothing to "see".You don't need a new thread because you already have the preeminent expert helping you already. I don't understand how you don't see that.
I took this video. I have a brand new spare cell, but I suspect it is the SWG, so do not want to mess with cell unless it is the best next step. What do you think? Many thx ! Google PhotosBasic AquaRite Diagnostics.
This is the basic information we need to know in diagnosing a problem:
- Report all diagnostic readings when you..
- 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.
- What are the first seven characters of the cell and box serial numbers?
- What is the actual salinity and how are you measuring it?
Cell Diagnostics.
Pressing the diagnostic button sequentially will display:
- Default salt display
- Pool temp
- Cell Voltage - When not generating, the voltage is about 30 to 32 volts dc. When generating, the voltage drops about 1 volt per amp of current.
- Cell current
- Desired output (% of the knob)
- Instant salinity
- Product name
- Software revision (r.XX)
- Cell type
Thx. That worked in terms of getting rid of the "hot" on the display. However, the salt countdown is only starting at 2500 and my level is 3000 ( using Taylor test kit). Appreciate any next steps you can recommend. cheers !Try the new cell.
Hi, the salt readings done manually with Taylor test kit were 3200,3400,3200.Basic AquaRite Diagnostics.

To estimate the performance of the Aquarite cell, divide the instant salinity reading by the actual salinity. If the performance is less than 75%, the cell is failing and it's time to consider replacing the cell. You need to be sure about the actual salinity by using a salt test like the Taylor K-1766.

Check the instant salinity reading and then cycle power to reverse polarity and recheck the instant salinity reading. The numbers should be about the same +/- 200 ppm.
You can get the age of the cell from the serial number. It will be 3Exx, where xx is the year it was made.
Get at least 3 independent salinity readings to be 100% sure about the actual salinity.
