I have an active 20 thats just over 3 years old, its will turn on normally and start its forward and backward movement with the light blinking then just starts going in reverse forever. the impeller motor never turns on during this process, but the motor is not the issue. when the driver motor and LED is unplugged from the motherboard the impeller motor turns on for a few seconds before turning off. I am assuming a motherboard issue since each individual thing will turn on but it going into reverse forever instead of turning off like a normal failsafe has me hesitant.
