I have a Swim Pure Plus with a T Cell 15 going into it's seventh season. I've noticed it only seems to generate chlorine when it is first turned on, either via the timer or flipping the switch Off then to Auto. After it stops, if I switch to Super Chlorinate or turn to 100% it does nothing. All lights on the panel and display show normal operation (Power and generating light are on, no flashing no other lights on) and the cell was clean when checked two weeks ago. I'm wondering if I have the thermistor issue but my symptoms do not seem to be consistent with what I've read. Below are the operating and non operating numbers when scrolling through the display button. Taking the panel off the insides look very clean, fuse is fine and no bulging of any capacitors. The thermistor does not seem to be cracked or burned but I'm not exactly sure what to look for either. Any ideas???
