COR 20 not working

[mikus]

Hey all. I have a COR 20 that just stopped working. My Fusion dashboard is reading "VOLT" where it usually would display the operating %. Any ideas or experience??? Any help would be great! I am currently running air stone and a smaller, temporary pump for now.

Usually theres something in the impeller like a small snail. This has happened to me a few times. Once I took the pump apart and cleaned it it went back to normal operation. I've had mine for about 3 years now I think

Thanks for the reply. I took the pump apart completely and didn't notice anything visibly blocking or clogging the impeller. It was a bit slimy. I cleaned it in a bucket of rodi water, and reinstalled it. Same error reading.

Volt usually means the power brick is bad. I had 2 gone bad already with the same error message. Replaced it and it worked again. Very frustrating that the same thing broke twice. Many others have had similar issues. $50 for the brick unless you are still under warranty. Brs sells replacements for it.

The driver might be bad. If you're turning the pump off from an apex outlet frequently it will kill the driver. I learned that the hard way
