help with octopus 160 skimmer/sicce pump please

[kasha]

So while I was away this weekend my wife calls me and tells me the skimmer has been making this knocking sound for several hours that is different from the start up sound. I asked her to unplug it and plug it back in at which point she says that it is silent.

I came back today and found the same result. It makes a very quiet humming sound but no real sound. I took it apart looking for an impacted snail or something of that nature but found nothing. Put t back together and still no start up.

Its only 3 months old.

Anyone have any suggestions? similar experiences? Can there be a problem with anything other than the sicce pump if the skimmer body looks grossly normal?

Thanks

try plugging it in and blowing into the air line, it might have burnt up not being able to spin but still running, how does the magnet look ?

I always had to blow air in to get it started. Now even that wont help.

So actually it still works fine with the regular white wheel. Its like suddenly the purple wheel is to bulky and it wont spin. But why would this have suddenly happened? There is no debris around the parts to cause problems.

mine rattle on start up but when i put my finger over the water intake for a sec, it seems to correct it.
i am using the supplied mesh wheels.
