The wash pump, wash pump motor or drain pump all make noise when they're broken. You may hear a loud buzzing noise from the wash pump or drain pump. The wash pump motor often squeals or whines when its bearings go bad.
Try to clear the dishwasher chopper blade area:
A kernel of popcorn or a similar foreign object can drop into the chopper blade area of the dishwasher, causing a loud grinding noise when the pump runs. Remove the lower spray arm and the upper part of the dishwasher sump to access and clear debris from the chopper blade area. If the chopper blade is damaged, replace it.
