You might need the tri-sensor adapter. If you have one already installed, it might not have been installed correctly. Google for the installation instructions.

If the adapter is installed correctly, then you might need a new tri-sensor.

I opened the sensor, cleaned and replaced, worked not for long and revered back to same codes.
Still get good salt readings, 2.6.
My thought is just to replace cell and sensor.
One question though, on new sensor I noticed a small circuit board connected on the cable, this is for??

That's the tri-sensor adapter. That's probably all you need. It's sold separately.

Follow the instructions to make sure that it is installed correctly.
