Hydor Koralia 240 question

[sansouci01]

My 240 is starting to make noise. If I unplug it and then plug it back in, it's quiet. Is this something that needs to be taken apart and cleaned. It's only 3 months old..

Id pull the impeller out and make sure theres nothing stuck in there

If its too close to the top of the water this can happen
