I'm just putting my experience out there, as a warning to
others, to
make sure your filter is running immediately after power
outages. I
wonder of others have experienced this problem.
========================
I've had a few Aquaclears to not start after an outage but no
harm came
to the impeller well, the motor or the impeller itself. After
cleaning
the slime off the impeller magnet, and the well itself - they'd
start
right up again. My Fluval always started after a power outage.

This has been my experience as well (no damage), but I guess 30
hours
with extra heat from the magnetic field, and no cooling water to
flow
past caused the hot spot to warp the plastic, further seizing the
impeller.

This is worrisome for office tanks which are left alone for the
weekend,
and I don't see many practical preventatives (monitor electrical
current
to interrupt power, monitor water flow to interrupt power or clean

impeller well religiously). I suspect different filters will have

different susceptibilities to this failure mode.

I have heard/seen this before (rarely) so I too am curious on what

equipment this has been seen before.

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!
