You are in fireman switch mode,which means pool timer is ready to shut down pump. clk shuts down heater approx 15 minutes before pump shuts down. this lets heater cool down before pump shuts off.
I keep reading about why this happens, but no details about how to correct it!
I had the same problem with CLK. I found the problem to be the PC board connector that holds the wiring from the Fireman's switch was loose or dirty, and it worked again after I mechanically agitated it.
2/27/18 I found the root problem and it was the solder joints on the control board for that long connector associated with the Fireman's switch. The solder had cracked on some of the connector pins possibly due to cold solder joints, high vibration, thermal cycling, or a combination of all three. I used a soldering iron and some solder to reseat the affected pins and the heater has not failed since.
In the control pganel only three ?etter show up tjat FFL
