When I looked inside the motor housing I did not see any wear marks on the impeller & the impeller and motor housing felt smooth. If it were a 100% sure thing that sand that caused the issue(i.e. rough or scratched up impeller) then I would replace it myself, but it's not. When I cleaned the impeller and motor housing no sand came out, sand only came out of the canister itself. It seems to be being noisy for no real reason that I can find, and this is why I bought one with a warranty so that if something ever did happen to it, I could get it fixed. Possible that it's sand, yes. However I'm not positive that is what's causing the problem, because everything in motor assembly looks and feels fine.
Hell, if I had the money I would just replace it myself as it would be easier and faster than dealing with customer service.
I do own up to my mistakes, I'm not one of those people you guys seem to think I am, however I'm not sure it was actually ME that caused the issue with the filter because, like I said, it all looks and feels normal, doesn't look damaged. And it ran just fine the same day AND the day after the sand was taken out, so I don't know what's going on with it, it only started having the problem a few days back.
