SilverBlade86 Posted July 14, 2008 Report Share Posted July 14, 2008 My CF1200 is making REALLY loud noises when running. Seems to me like there might be something clogging the motor, but I can't seem to find a way to open it up. Any ideas anyone? Quote Link to comment Share on other sites More sharing options...
Afrikan Posted July 14, 2008 Report Share Posted July 14, 2008 Have you checked the impellor? I take it you have, but thought I would just ask just incase 8) Quote Link to comment Share on other sites More sharing options...
SilverBlade86 Posted July 14, 2008 Author Report Share Posted July 14, 2008 Whats an impellor? I was testing it out just now and I took everything out, and just let it run without water and it still made the noise. Quote Link to comment Share on other sites More sharing options...
livingart Posted July 14, 2008 Report Share Posted July 14, 2008 as afrikan said it may be impellor has come loose on rubber mounts or impellor has come adrift on its magnet impellor is the little fan thingy that pushes the water through unclip top off filter and turn on you should be able to see impellor turning Quote Link to comment Share on other sites More sharing options...
Afrikan Posted July 14, 2008 Report Share Posted July 14, 2008 The part that spins around.... inside the head of the filter... Sometimes when they need replacing the filter starts making a horrible noise... or if something is caught up around the impellor... Quote Link to comment Share on other sites More sharing options...
SilverBlade86 Posted July 14, 2008 Author Report Share Posted July 14, 2008 Ok, I'm gonna go take a look at it again. I REALLY hate taking apart the filter though, water flies everywhere. Will be back in 5 minutes. Quote Link to comment Share on other sites More sharing options...
SilverBlade86 Posted July 14, 2008 Author Report Share Posted July 14, 2008 Interesting. I took out the top part, turned it upside down and turned the filter on and the fan wasn't moving. (I assume that was the fan I was looking at). Yet I know the filter works because I could feel the water pressure going against my hand when the filter is turned on. Whats going on? Edit - Sorry, I was looking at the wrong thing. Yes, the impellor is working and it's the one making the noise. How can I get to it and fix it?

Afrikan Posted July 14, 2008 Report Share Posted July 14, 2008 You should be able to remove the impellor and check it... sometimes they just break down and you need to replace impellors on canisters.... easy enough done and you can still get impellors for that model... Just check that there isn't something clogged up inside where it sits.... Quote Link to comment Share on other sites More sharing options...
SilverBlade86 Posted July 14, 2008 Author Report Share Posted July 14, 2008 Ok, I finally found out how to take it apart. Now, it seems to me that the noise is because the magnet isn't holding the impellor as hard as it could. Since it isnt as magnetic as before, when the impellor spins it rattles. Is there any way to fix this? Quote Link to comment Share on other sites More sharing options...
livingart Posted July 14, 2008 Report Share Posted July 14, 2008 sorry used the word magnet as it was easier you will probably find that the impellor plastic has worn down and won't drive the impellor properly they have a plastic piece to catch the "fan" and drive it round ask at local fish shop for replacement impellor, quoting brand and model nos should be delivered in a couple of days Quote Link to comment Share on other sites More sharing options...
Afrikan Posted July 14, 2008 Report Share Posted July 14, 2008 Yeah I would get replacement impellor, as livingart says 8) It sometimes pays to have a spare incase it needs replacing at anytime 8) Quote Link to comment Share on other sites More sharing options...
suphew Posted July 14, 2008 Report Share Posted July 14, 2008 It's not abnormal for the impeller to move a bit on the magnet, they usually spin 1/4 to 1/2 a turn. The movement you need to look for is sideways and up and down, or if it turns completely. But the most common problem is the impeller and magnet moving on the shaft. New impeller are pretty cheap so there is no harm in buying one, but you might just find it was air trapped in the canister making the noise.

SilverBlade86 Posted July 15, 2008 Author Report Share Posted July 15, 2008 Hmm, ok. I'll buy a new impeller tomorrow. How much do they cost? Quote Link to comment Share on other sites More sharing options...
suphew Posted July 15, 2008 Report Share Posted July 15, 2008 Check out a new shaft as well. Once you have replaced both parts it will basically be a new motor, there are no other serviceable parts (in the motor) Quote Link to comment Share on other sites More sharing options...
