My ultra flex 2 system won't rotate between stations. All I get is the rapidly blinking red LED light. I have the grey sensor.
I came across your post in the trouble free pool forums regarding the ultra flex 2 pool cleaning system. Mine is acting up as you described in the past. I have replaced the motor and the control box including the wiring between them. I am at a loss to figure out what else could be wrong. Do you still have the trouble shooting guide and would you be willing to send it to me?
