Hello all. I am have a bad sound on a normal cycle at like 45 minutes. Its like a loud grinding sound. i have take it apart as far as the chopper assembly. and cleaned out some gunk that was in there also. I happen usually at the 45 mark when i think it does a big drain of the water. cause when you start it like around 70 or so it does a drain there. it doesn't do that noise at that time. But at 45 minutes its making that loud grinding sound. Should i replace the drain motor or is there any other test i can do to fix this. Thanks.
