Hi,

Yesterday my 2233 (I believe) started to make a rattling noise. At first it sounded like there was some debris in the pump interfering with the impeller.

After opening it, I saw, what turned out to be, a spikey, white rubber ball in the outlet pipe. I ignored it at first (and accidently let it fall into the garbage disposal :( ).

The shaft and impeller seem to be in good condition, but the impeller has a lot of axial play on the shaft and seems to jump around when the power is turned on, causing the rattling noise.

When I looked at the parts schematic, I saw the ball and a cage shown (#7481020). Mine is obviously worn (I didn't see the cage), but I don't know where they go, or if they are causing the problem.

Perhaps there is another part missing.

Anyone have any experience with this filter.

Thanks for your help,

Tom
 
Partly solved

Found the manual which has a much clearer schematic than the one on the internet. Now I know what the ball is for and where it goes -mine is extremely worn.

Now, will changing the impeller and/or shaft fix this thing?

Thanks

Tom
