My Emperor 400 has been unusually loud lately. I broke it down and cleaned it out the other day and it is still just as loud. the major source of noise is coming from the impeller- it just makes this constant loud vibrating sound. When i first got it, it would make this sound on and off, when it wasn't it was very quiet. I assumed as it broke in that it would improve and it definitely hasn't. Anybody have any suggestions?
