Aquarium Advice Addict

Liverpool, UK.
I've had this FX6 set up for around 6 months now. It has always been reasonably silent (as silent as a filter that size will ever be).

However, I've just given it a clean and decided to check the pump out of curiosity.
I got out the manual and followed the instructions on taking apart and putting together the pump unit.

I set it back up on the tank and now the pump is making a HORRENDOUS buzzing noise.
What might I have done wrong?

One thing I did notice was that the O-ring between the impeller itself and the red housing isn't actually doing anything?
It's completely loose with no obvious groove to put it in.

Please help me someone!

Oh never mind...

I got it working...

It seems that you need to do everything twice before it works with this FX6...
