Once again my fx-5 is acting up. It wont pump water out into the tank now. I cleaned the impeller sunday and all the media. It was working last night and this morning but i hooked my spray bar back up and now it wont start. It tries to run and then stops. Any suggestions would be awesome.
 
Is it kinda new? When I got my two, on two seperate occasions they both wouldn't start up after I turned them off. I cleaned the impellers after those two times, and they started back up. Those were the only two times that that happened, and now they start up every time.

Another thought - do you fill it with 2.5 gallons before you plug the power in?
 
This is the first time ive had a problem with it not starting and its pretty new maybe two years. I just cleaned the impeller a few days ago also. It is filled water also so I ran out of ideas, i guess i can try to clean the impeller again.
 
It tries to run and then stops.

This confuses me. Does it pump water normally and then stops pumping although the pump is on? can you hear the pump?
 
Is the return line submerged? I know my one Eheim wouldn't start unless the return wasn't submerged. Haven't had any issues with my FX5 so I'm throwing out guesses here.

If the fx5 is filled with water, you can leave the intake out of the tank and the pump will empty the canister of water while still producing a lot of flow
