Replaced gear case and wash plate and tested unit; dspstn on spec-tagged invntry: 1 W11449840 GEARCASE

Customer says unit is having intermittent issue with not finishing cycles. I could not get unit to have this issue and there are no error codes stored. Customer also states that the squealing is still there and when I checked underneath and rotated the cam I noticed the sound of loose change underneath the washplate that is getting caught in the grarcase underneath the wash plate and possibly grinding the gears causing the noise. I tried to remove wash plate and clean out underneath but the wash plate would not come up so I ordered a new washplate and gearcase. will have to break the old one off; ordrng 1 W10902814 (Washplate) and 1 W11449840 (Gearcase)
