I have the Ultraflex 2 version of the caretaker in floor system. Tonight I noticed the red LED light on the UltraFlex 2 box blinks nonstop and the stations are not rotating. There is nothing in the manual regarding the LED lights and why they are blinking nonstop. I checked the motor and it is free of debris. I also checked the voltage on the controller side via terminals 1 and 2 (Brown, Green wires) and I am getting a burst of power every 15 seconds to the motor or the sensor. Pressure gauge is at 20 and goes to 0 when filter is off. Also, when I cycle the power on and off the LED stays solid red for 10 seconds and the motor spins and cycles past a station. The motor doesn't feel too hot either. I replaced the entire motor housing 2 years ago with new sensor, PCB and plate. We also put new gaskets under the plate at that time. All of this work was done by a great man who passed away and now I have to attempt a repair myself. Could this just be a sensor issue? Any help is appreciated.
