Coralbox DCA4000 stops working without warning

[Stephen Glover]

I was walking by my tank when I noticed that the water level was low. My Coralbox DCA4000 return pump wasn't running and the blue lights were flashing. I reset the power and it came back on. I don't feel comfortable using this pump as I never had an issue with the Eheim it was replacing. Any one else having issues?

Hey Stephen,

Can you please tell me the specific error code that was displayed on your pump's controller? The controller will tell you what kind of error it encountered if the pump is off.

Please contact our support team if you need further assistance https://reefbreeders.com/contact/

If it happens again I will take a video of the flashing lights. I didn't think of doing it at the time.

I just looked at the error codes and I believe it was the abnormal input voltage code. What would cause that? I have the pump plugged in to a reefkeeper elite which is plugged into a GFCI outlet

It could be the power supply- or a power surge/voltage fluctuation. If it happens again please note the error code and contact us directly for support.

Sometimes gfci's go bad. May want to check that also.

I've tried reaching out to your support and I have not received a reply. The pump now doesn't even turn and is flashing a code not present in the manual. Luckily I still have an old Eheim which I was able to use to save my tank. The 3 left lights and the furthest right light blink

. Video attached.

Well after soaking it for 6 hours the pump started running again. I'm now assuming these pumps need to be cleaned much more than the old AC pumps. I'm thinking of setting a reminder to clean every 2 months.

Hey Stephen,

I searched your name and I do not see any emails in my system other than an email thread from 2019. If you don't mind PMing me your details I will look into that right away.

Also please do keep in mind that we are not open on weekends. I do pop into the office but it is outside working hours, so I may not be able to get back to you on a Sunday.

The error code you have is in the manual as "Pump Stuck- Unable to turn" which means the impeller may be calcified. I would check the bushings on the back of the impeller and make sure that they are not bound up. If you need new bushings we have them on hand.
