I bought an eheim 2217 for my tank and set it up and I cannot stop this annoying rattling sound. I have spent about 3 hours on this thing and still no solution.
I have tried:
- tilting making sure there are no air bubbles
- taken the filter apart and cleaned the impeller etc
- made sure there are no kinks in the hoses
- made sure the taps are fully open
- Made sure the media and plastic parts are positioned correctly
- left it running for an hour and still noise
I have had an aqua one cf-1200 for this tank and it's so quiet so I hope that I can fix this as I have heard good things of eheim
Thanks

Any help greatly appreciated

Did you try gently shaking it while it is running to ensure all air is out of it?

[slink]

Did you buy it new? I agree with werdna it's happened a few times with me and I just give it a really good shake.

[smirq]

Not sure it's the best solution, but sometimes I'll turn it on & off a few times to force out trapped air. 

[DavidK]

Yep have given it a good shake to the point where no air bubbles come out of the outlet
And turned it in and off to be sure as well

Is it 2nd hand or new?

[DavidK]

2nd hand

[TheTexasCichlidMasacre]

did you buy it off someone on here?

[Kleinz]

Clean it or at least the hoses.

 

Check the ring magnet in the impeller is not cracked or chipped. Same with impeller housing. Could be hairline crack.

 

Also may not be correct impeller.

[silverscreen]

check the rubber gromets where the impeller shaft pushes into...they might be worn or not there at all...should be one in the motor and one in the locking cap on top....i have lost one before and the pump rattled.

[DavidK]

Yeah, but in guessing its just something I've done wrong as this is my first eheim
I'll give it a good look tomorrow and let you know
Thanks all

When you place the impeller back in after cleaning should it be dead center? Because mine is slightly off

[Robbotheyobbo]

if its not in the centre, then i woluld say your missing the little rubber cap from the end of the impeller shaft

[DavidK]

I have both rubber caps, but it's not center when I put the impeller over the ceramic rod
Once I put the plastic part on top I think it moves to the center

[DavidK]

Should I try some aqua safe or something around the impeller?

[JackMack]

I am yet to buy an eheim but I suggest shining a light into the impeller holster and seeing if there is anything preventing the rubber cap from sitting straight.

Good luck

[Kleinz]

sounds like if it is not centred by the arbor, it may be too small. Should be too snug in there to be anywhere else but centre.

Hello DavidK,

 

I had the same issue with my 2217.

 

If you look at your impeller you might notice that there is a gap between the magnet and the white cap, this can cause it to rattle, the magnet should not be able to move (up and down).

All you need to do is replace the Impeller and your problems should be all fixed.

 

Regards,

Leif.

Okay, i'll buy a new impeller  

What do you mean by the white cap? I don't know which part you are referring to sorry 

[waxy]

Yep I had the same issue a while back. The impeller looked fine but I replaced it as a last resort and it was fixed. Quiet as a mouse.
