Our washer is working except that it has started to buzz during aggitation cycles. It does not do it all the time and it hasn't interfered with any of the cylces. I read a post that sounded similar and it was a tooth in the pump, but the video link was down and it was not the same washer. Could this be our problem as well (unlikly it is a tooth, but I can imagin other small things could have made their way in :) )? I have never done anything handy with the washer before, so any tips would be very helpful! Thanks!
