I bought a used magdrive from a fellow reefer here. For some reason it sticks when you first plug it in and I have to manually spin it to get it going. Once I spin it..it's fine. But if I unplug it or if the power goes out I have the same problem. I've read where this was a common problem across the board with Magdrives. And due to my sump design this is going to be a pain to deal with, if I target feed etc. I contacted Danner, and they said since I bought it used, it's no longer under warranty. They refused to even give me a "well it's most likely this...???" I even offered to pay to have it serviced/repaired, since it wasn't under warranty.....and again they refused. I figured with 50 years of experience as they claim to have that they would at least stand behind their product, but it doesn't seem that way. After a few heated emails back and fourth and the lack of customer service, I now will not buy anything that Danner makes from now on. I've cleaned the impeller really well and inspected the shaft for cracks and found nothing. Anyone have this experience and how did you fix it? It's 35 bucks for a new impeller, but I don't want to buy if that won't fix the problem. That's 35 bucks I could put towards a new better pump.
