Eheim noise/ low flow

[Seweryn]

Hello peoples!

Got a question about my 4 month old Eheim 2213...
After running silently for a while, it has developed a rattly hum when
running. I cleaned the canister out, squeezed the filter pads, rinsed the
substrate, made sure the tubes were clear, and disassembles the outer pump
components and cleaned them. But it still rattles! And it seems that the
flow rate has decreased. The only addition to the filter media was to add a
thin extra layer of floss right before the white pad. Any ideas what's going
wrong?
Along the same lines...
- When (if ever) should I replace the coarse and fine substrate??
- Do I have to replace the white pad every few months, or can I just give it
a good rinse? Could I use some generic floss instead?

Thanks for any advice,

- Seweryn

Are you sure you haven't got air in it?
Make sure the canister is absolutely full of water before turning it on.

Make sure the rubber gasket around the top is intact and sealing. Sounds to
me like you are taking in air around the top, and that also causes the leaks
you describe.... You can get replacement gaskets easily

Shake it a little to see if there is alot of air close to the
impeller. USUALLY Eheims are great @ removing air though.
Also ty removing the floss and see if that fixes it since that is the
only other change you have done.

We give our pads rinses

My guess is that the impeller has worn down around the shaft. I have
a Fluval with a worn impeller that acts likes yours does. Open it up
and pull the impeller out. If it seems loose around the shaft, then
you should buy a new one. The cost is about $13.

Here are a couple of links. I can't vouch for either, but they have
the information you would be looking for:
