My Fluval 405 Filter won't turn on when it's plugged in

    This filter is about 3 years old. Worked fine in my last home. We moved, set up the tank. Once the water was manually being pushed through both hoses, I plugged it in and nothing no hum, nothing at all. I plugged in something else to make sure the plug was working and it is. Any idea? Could it be something easy or do you think it's dead for good?

    Thanks!

    Welcome to the forum

    Mine goes dead from time to time. I fool with the wire and shake the filter to get it going.

    Never had that with my 405. If its not running properly then its usually a broken part, or i've not got it seated properly.

    Check the ceramic impeller shaft. They a hard as nails but they do break for some reason. And be careful removing the well cover and don't pull it out using the tabs. Push the tabs in and hold, then lift the cover with a screwdriver or something.

    My 405 does that - it'll just stop working, then it will resume on its own some time later.

    I have a Fluval C4 filter, and it often will not come back on after I unplug it to feed my fish. You have to detach the impeller casing from the filter, mine just twists and pulls out, not sure how yours is, and just plug it in while it's not attached (do this over a bucket, as water WILL come out), it should work just fine. You could even try taking the impeller out of the case and cleaning the inside of the impeller housing with a q-tip... When you twist the impeller housing back onto the filter housing, be ginger with it, and do it carefully, or it could get jammed again. Fluvals are known for this kind of behavior, something I wasn't aware of before purchase... my next filter investment will be an AquaClear!
