Update: I replaced the cell with a brand new one, and the unit is working properly now.

I have been following the troubleshooting in this guide and would welcome feedback on the results that I am getting. https://www.troublefreepool.com/wiki/index.php?title=Hayward_Aquarite_SWG#LOW_SALT_Message_.26_0_Salinity.2C_0_Amps I have verified the voltage across pin 1and 2 to the cell as...

I have a Hayward Aquatrol that was working well up until today. Suddenly, the unit is reporting 100 ppm salt when previously it was 3000 (I have also independently verified the salt content). If I try to reset the salt content, the instantaneous salt value is 0. I haven't cleaned the cell with...

I disconnected/reconnected the pilot tube and relit the pilot this morning and now it is generating 650 mV and the heater fires.

Hi, I have a Hayward H250 Millivolt heater that is around 9 years old. I can get the pilot to light and stay lit with a nice blue flame and it is generating around 600 mV. When I turn the heater on and turn the thermostat up, the heater won't fire. If I jump across the TH terminals the...

Do you have a suggestion for how to verify that? Checking the voltages coming into the LCD?

Are there any components on the DSP that could be bad causing the issues? I am not adverse to swapping out some resistors if needed.

I got it used with the pool - I think it is 7 years old.

This is exactly what I am wondering. Are there any more diagnostics that I can run? In the diagnostics manual where it says to check the voltages on pin 2 and pin 4, do they mean check the voltages between pin 2 and pin 4, or the voltages from a reference to 2 and from a reference to 4? When...

I also followed the steps in this post, with no change. https://www.troublefreepool.com/threads/aqua-rite-display-issue.145855/ One more detail - I had to replace the current limiter on the main board. After replacing the current limiter, more cells were being displayed on the LCD than before...

Hi - my Aqua Trol LCD is not showing all of the digits that it is supposed to. I have worked my way through the trouble shooting manual to test voltages and resistivities and everything seems OK. The one part that I am not sure about is the last voltage test - am I testing the DC voltage...

Thanks for the info in this thread - I found that my current limiter is also cracked and have ordered a new one to replace it. My LCD display is also malfunctioning - it does not display all of the digits for the various diagnostic information. Could this be linked to the current limiter?
