Hi. My aquarite Hayward t 15 isnt showing salt levels.. instant reading or otherwise. Temperature seems to be showing, at 23 Celsius (I think) currently, which relates to the reading on my heater, 73 degrees f.Could be the thermistor. Take the front cover off and it is a large black wafer the size of a quarter located on the upper right side of the main circuit board. If it looks like it is flaking apart, it might be bad. The part is cheap and if you have any soldering skills, it is an easy fix.View attachment 446198
I have checked the thermistor.. it's not chalky, or broken but the connectors to the board are ... rusty? I'll try to provide picture.
If the temperature is accurate.. can the thermistor still be the problem?
