Welcome to the site T4Duzan. When you are cleaning, pay particular attention to cleaning the intake tube and when it is going back together, make sure the intake tube is seated properly in the impeller connection. While the filter is apart for cleaning, remve the impeller itself and clean the hole it came out of with a bottle brush. If there is any buildup at all in that area, it can really affect the impeller's performance. Naturally, when putting the impeller back in, make sure that it is seated properly in the little rubber bearings on both ends of the impeller and that it turns freely in place before you assemble any further.
