Well, just had my first hiccup with my new Coralife Wavemaker DC5800. One of the pumps just suddenly stopped working. At least the controller handled it well, by shutting down with a flashing red light. Then just by unplugging one pump at a time, I quickly isolated which pump wasn't working. But there was no prior warning, like noise or vibrating, just a sudden stop and shut down.
I took the pump out, pulled out the impeller assembly, and had a good look. Couldn't see anything wrong. I then cleaned it, and put it back together. Everything seemed to fit tight, and no sign of any wear. I plugged it back in and it worked again, just fine, as before, and no noise.
So not sure what was wrong with it. The only theory I have is that maybe the shaft worked its way out of one of the rubber ends, and just jammed then and stopped. I have it on the Turbulence Mode, and this pump was set for 10 seconds. Maybe that is too hard on it with the constant ramping up and down, and may have caused the shaft to shift to one end. Just my theory...
I will continue to keep an eye on it, to see if it happens again. Coralife gives a lifetime warranty, so if anything is wrong, I would expect a replacement of the defective part.
If anyone else has had any problems with these, would like to hear about it. I know they are still fairly new. But I know there are some out there, judging from the back order statuses of the retailers that sell them.
