No, it doesn't need washing again- just make sure the intake is not close to the sand, stab a hole in a piece of coarse sponge to cover the intake, and ensure the sand has settled after pwcs before turning the filter back on.
I have a couple of HOBs which I use purely for back up BB, and sometimes they have trouble starting back up. Sometimes jiggling the bit that sits over the impeller works, other times I have to get very technical and bang the whole thing a couple of times. :Hide: I probably should clean the impellers more frequently, but unlike my canisters, where I can just shut the valves and take the lid off to clean the impeller (without disturbing the media or the tank) with the HOB
I always end up making a mess inside AND out of the tank, and have to disturb the media to get at the impeller. Then I have the problem of fitting it back together so that the impeller can spin freely (the screeching noise when i get it wrong cuts through me!)
I have to say- you've got me worried because I'm about to set up a tank with sand!
