COR 20 Failed

[redpine42]

So after feeding today my COR20 reports an overvolt. I pull it out see nothing in the inlet or outlet and the impeller spins freely. I put it back in the tank and now I get a Volt error.

Any suggestions?

LED 3 is flashing. Power brick LED is green. Good thing I have a backup pump.

The COR-20 driver is connected to an APEX system but it has no 24VDC input power (LED #3 will be flashing)
The input power voltage is low (LED #3 will be flashing)

Take the pump apart, reseat the o-ring, as well as clean the impeller....

Did all that working with Neptune. Looks like it's dead.
