My filter is not pumping out - the top of the fluval is getting hot and it seems as though the impella is not turning

The mfgr forgot to install the impeller SHAFT on my new 306, so I had to mail the whole thing to them AFTER I contacted them (their parent Co.) so they could tell me that, and send it all back, with a shaft I had to install myself. No shaft means the impeller will catch sides or not even turn, causing overheat and no pumping... poor quality control!

Is this an initial set up?First thing to check is that you have the intake and discharge lines on the correct sides. Second is something clogging the intake.

I would try to disasemble the cover and impeller and reasemble make sure all parts are on correctly and make sure to prime.it correctly,DO NOT plug in the filter until all air is out of the system. Good luck!! Hope this helps!!

Hopefully there is no sand in your filter, that would mean it broke! There should be a screw to anchor it down with on the outside of your filter.

Make sure that when priming the filter, you need to fill it to the very top. Then turn the fill cap so it's snug. this should relieve the pressure, after about 3 minutes the buzzing/humming should stop. good luck

This has happened to me a few times. I couldn't figure it out at first, but then I realized that it was getting a little clogged. I think I'm due to change the filter, but today when I was cleaning it, I blew into the black hole so that water came out the other end and made sure I the motor really well. Put it back together and the bubbles started coming back up through the top. Ashtyn is right too -- you have to really make sure the two pieces line up perfectly together.

Hi Barbara, The only place these things will rattle is in the impeller assembly, it sounds like the impeller is not correctly seated in the housing and not making correct magnetic contact with the motor, as a result your impeller isn't turning enough rpms and not drawing water up through your intake. If the water level in your filter has dropped too far you may have lost your prime. Before taking the impeller apart, make sure you manually fill your filter with water, then turn it on and see if it draws water. If it doesn't, don't hesitate to take it to your local pet store and ask them to check the impeller assembly remember, they don't want to lose your business. Good luck.

You might have some Debris stuck in your impeller. You will have to remove the impeller from the motor section of the filter. Usually with a small twist and a pull, you should be able to access the impeller. Be sure to clean it and check for Debris or broken parts.

sounds like the motor is crapping out. i used this thing for a short time and didnt like it and went back to old faithful "whisper 60s", they last forever, work great, are mostly quiet, gotta pull em apart and clean up good every once and a while but they really are the best hang on filters u can get. ive been in saltwater forever and have used EVERYTHING you can imagine, stick with whispers..

I had that problem. There is a filter in line. Cleaned it and the flow was fine again.

Sounds like you got a defective one. Mine was easy to swap out, no issues. I made sure the center post was properly inserted into the bottom of the valve. I swapped out my old one because it was doing the same thing, letting water out of the waste when in filter mode. It seemed to be related to the lack of spring tension keeping the handle down vs anything else. Good luck.

This happened to me as well on the 2nd day. Initially, I soaked my filter many times and that didn't help. Eventually it finally stopped today after I shook the filter. It was so frustrating. I guessing maybe this has something to do with the fact that there are 3 layers of the filter materials. Perhaps the mineral particles shuffled to the very bottom but they're supposed to be at the top, according to the pic in the brochure. This is just a guess.

The valve has been in the open position long enough for sufficient filtered water to have flowed to suggest changing the filters (probably not the RO membrane, just the other three). Just pull the battery and put it back to reset.

You may need to flush the whole filter- run the black plastic part under hot water. Or... Is the black stuff the charcoal leaking? Or is someone over feeding the fish?

I have mine conected to Odyssea CFS 500 Canister Filter & it works fine. May have to get some different hose conectors. I think the Fluval has smaller hoses, no biggy. Also will need to get a shutoff valve to control water flow. That is something I did too. I really don't see any reason why it should not work. Good luck!! Linda

Have you cleaned the pump and filter after you do you need to plug the pump in and flush the rest of duribes out not in the tank but in a bowl or pan usually this will eliminate the problem I quite using the filters because of this problem

I that happened to me.. basically you over filled it and the pressure pushed the top tank up.... fill up to the top of filter, or just below. It's good to go

I had this problem as well, make sure the water tank is placed correctly. My tank wasn't pushed all the way down. I hope this solves your issue as well.

Make sure the pump is properly seated into its base and the suction cups are properly secured the back. Mine was a little loud as well until I did this. Also if it starts to overflow it's because the filter is dirty
