My experience last night was that after noticing reduced water
flow
with my fluval msf 404 I unplugged it and plugged it back in and
noticed no water flow at all. Then I took the impeller well cover
off
and discovered the ceramic shaft sticking to the cover instead
of
staying in the impeller well. So I corrected it by removing the
ceramic shaft from the cover and inserted it back into the tiny
hole
in the bottom of the impeller well - and now it seems to be
working
perfectly. I just thought I would share my experience with these
things too. Thank goodness they are as reliable as they are
(canister
filters). Good luck and later!



When installed, I think the 404 shaft is in both the well cover and
a
black rubber washer at the other end. Which end it sticks to
during
disassembly is not material to its operation. Your re-installing
it
probably dislodged any mulm which was preventing the re-start.

Interesting point netmax. I don't want to be picky but the hole in my
fluval impeller cover goes all of the way through it, so conceivably
gravity could easily pull the ceramic shaft down to the filter
chamber cover, probably removing the ceramic shaft most of the way
out. The only 2 things keeping my impeller in the impeller chamber is
1: the rubber hole now gripping the ceramic shaft, and 2: I lay my
fluval on it's side because the tank it filters is so low to the
ground and it doesn't hurt any, so gravity works differently for my
setup. Mulm in the impeller chamber can definitely be an issue at
times. The fluvals have self flushing impeller wells which probably
contribute to the fact that I can get away with not cleaning the
fluval often, but apparently mulm can definitely make hagen
powerheads unreliable at power on (start up). If the power goes out
and back on, occasionally the hagen powerheads will stick and do
nothing if they aren't kept clean, and there is a possibility that
cleaning it might not be enough (I don't know yet - still observing
my cleanings). Good luck and later!
