The unit washes the dishes just fine - so if it is an easy fix - I'd just as soon fix it - then replace it.
I saw on this site another post talking about how the bearings could begin to leak and that would be seen by water found under the motor. I took the front kick panel off and saw no signs of water. I recorded the sound and can email it to you if you send me an email address (the file is too large to be attached to this post). Attached is a picture of the bottom of the unit showing no evidence of water.
I wanted to know how to take off the top filter screen as there was mention in another post that crud could get in the food chopper mechanism so I included a picture of the inside of the unit with the spray arm removed. I've felt all around the bottom and can feel no crud - but if I am supposed to remove the top I can do so - just let me know what screws to remove.
Thanks for the help.
Hmm -only the first picture got posted so here is the one of the inside of the unit
