Hey guys just got my two 6025s back from warranty (They were the original batch). Construction looks great, very solid. However one of them works like a champ, the other's impaler is just hopping. I attempted to restart it a few times, no dice. I removed the impaler and put it back in, nothing changed. I even had it on and pulled it half out of the water and put it back in, that was the trick to get my old 6025 to work again. Still nothing. Any ideas?
